Heard of mini neptunes and gasoline dwarfs? This is a brand new one: Decrease Earth

The planets in our solar system are roughly divided into two groups: small, rocky worlds like Earth and large gas giants. Before the discovery of the exoplanets, our solar system was believed to be very typical. The light and heat from a star push the gas towards the outer solar system, while heavier dust stays closer to the star. For example, a solar system has nearby rocky planets and distant gas giants. But we now know that planets and star systems are much more diverse.

The most common way to categorize exoplanets is by their mass or size. Jupiter worlds are the largest, then Neptunians, super-earths, earth-sized and lower-earths. Obviously, the greatest interest is in potentially habitable Earth-like worlds that would have similar mass and orbit as our planet. But there is still much we do not understand about other types of planets. For example, super-earths are slightly larger than Earth, but they are terrestrial planets or more gas-like. Because of this, the group is sometimes further divided into those smaller than about 1.6 Earth radii, which are likely rocky, and larger super-earths, often called mini-Neptunes, which are likely to have more in common with gas giants.

Since we cannot observe most exoplanets directly, one way to study them is to look at their statistics. For example, there is a statistical gap between the great earths and mini-Neptunes. This 1.6 earth radius gap indicates separate forms of formation. Things are less clear for lower-earths. Planets the size of Mars or Mercury are hard to find, which is part of the reason why there are so few known exoplanets underground. This makes it difficult to study their statistics. However, a new statistical study suggests an interesting origin for these little worlds.

Because the number of confirmed lower earths is so small, the team examined a collection of candidate planets. Observational data suggests they might be planets, but the data isn’t strong enough to be certain. They have filtered everything out of more than 4,000 candidate planets, except worlds with short orbital times (less than 16 days) and a size of less than 4 earth radii. That left 280 candidates, which is enough to compile some basic statistics.

One of the things they found is that the size distribution for these exoplanets follows a power law distribution. In other words, the statistical number of planets increases by an order of magnitude (or force) as they get smaller. The size of the asteroids in our solar system follows a power law distribution, and we know that the asteroids formed long after the classical planets captured much of the material of the early solar system. Since lower earths follow a similar distribution, it is very likely that they formed later as well.

The authors refer to this two-stage educational process as Generation I (large planets) and Generation II (terrestrial sub-earths). If this idea is correct, it could explain why super-earths are more common than truly earth-sized worlds. If planets like Earth were Generation II, they would be pretty rare. However, it is important to note that the sample used is quite small. While the study is interesting, we need more data before we can draw solid conclusions.

The promise and hazard of satellite tv for pc mega-constellations

Constellation satellites around the earthGenevieve Poblano / Digital Trends Graphics

If you’ve followed SpaceX’s Starlink project to create global broadband Internet, you’ve noticed that the company regularly launches not just individual satellites, but entire batches of 60 satellites at a time.

These stacks form a network in the sky called a satellite constellation, which provides near-global coverage in ways that a single satellite cannot. And not only SpaceX uses this approach – there are satellite constellations that companies from Amazon to its subsidiary Kuiper Systems to Facebook are working on as part of their Athena project.

But not everyone is on board to launch so many satellites into the night sky. Astronomers in particular have complained that such constellations jeopardize their ability to collect data with telescopes and hinder scientific progress.

To understand the pros and cons of this complex problem, we spoke to two experts: Olivier Hainaut, astronomer and lead researcher on how satellite constellations affect astronomical observations, and Brad King, CEO of a company that makes propulsion systems for satellites in the US -Military deployed in constellations.

The good thing: What satellite constellations can offer, individual satellites cannot

One of the greatest advantages of the constellation approach is that networks can easily be updated over time. If a system has a single large satellite, that hardware can take years to build and develop. Once started, it is extremely difficult to add features or improve the hardware.

With a constellation of satellites, you can gradually improve the hardware at startup. For example, if a company starts deploying satellites and develops more accurate sensors after a few years, they can easily install and deploy the new sensors in the next row of satellites. The existing satellites can continue to work together and the fleet can be gradually upgraded.

So the constellations are constantly being updated, said King, the CEO of Orbion, a small propulsion company that is currently providing the propulsion system for the Defense Advanced Research Projects Agency’s blackjack satellite constellation.

“If you fly 100 satellites, you don’t fly 100 satellites and wait 10 years and then launch 100 more,” King said. “They continuously update the fleet at around 20% of the fleet per year.”

It also means they can weather budget cuts on long-term projects by reducing the overall fleet, rather than scrapping a project entirely. This is important with government programs that may run for a decade and then cut their budgets.

There are additional specific benefits to using constellations for governments and the military. “The main benefit is resilience,” said King. “What you can do with a constellation, you can’t do with one [satellite] is that you can be resilient to attack. If you have a very large, very valuable satellite in orbit and you have an opponent who wants to refuse to use that satellite by damage or other means, it really only takes one bullet to take this entire ability off.

“When there are multiple internet providers in a region, people can access the internet more freely without government restrictions.”

“If you instead let 100 satellites share this functionality, your depth of attack would have to be much deeper to compromise functionality. So it protects against attacks. It’s not a big, thick, juicy target that will trick an enemy into attacking it. “

Once a constellation is in place, it can be used for all kinds of communication purposes. SpaceX’s Starlink program aims to deliver global broadband internet that has many potential benefits. In addition to the potential to provide internet access to poor or rural areas with little or no internet service, being able to track planes and ships around the world could also be invaluable for security reasons. The availability of multiple Internet providers in one region could enable people to access the Internet more freely and without government restrictions.

The bad: why constellations have some astronomers in their arms

As with all technological advances, the launch of satellite constellations is fraught with problems. Last year there has been a sometimes heated debate between SpaceX and the astronomical community over the launch of Starlink satellites.

When satellites are launched, they can leave trails of light in the sky, especially at dusk. While some may find these trails beautiful, they can affect astronomical readings because they’re much brighter than the stars or galaxies astronomers are trying to observe. There is also a question of whether Starlink satellites, which are in particularly low orbit, are visible to the naked eye and will affect readings once they are present.

Image showing the disturbance of astronomical observations caused by an earlier Starlink launchAround 19 Starlink satellites were imaged by DECam on the 4-meter Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO) shortly after its launch in November 2019, creating light pollution that negatively affected astronomers’ ability to observe the night sky . National research laboratory for optical infrared astronomy of the NSF / CTIO / AURA / DELVE

The International Astronomical Union issued a statement in the summer of 2019 and a follow-up in February of this year. Both expressed concern about the negative impact the proposed megaconstellations of communications satellites could have on astronomical observations, citing Starlink, the Iridium satellite constellation, OneWeb, and others.

SpaceX quickly addressed the problems Starlink was creating in optical astronomy and worked with astronomers to find a solution. First, they tried painting the satellites a darker color, which, while diminishing their appearance, was not enough to please astronomers. So they moved on to a new design that included a visor for sun protection.

“That’s really smart,” said Hainaut. “Because if the satellite is not illuminated, it is completely dark and invisible. This means that the visor can hide most of the satellite. The way the satellite is set up means you can have a sight where you can see the back of the sight when viewed from the ground so it’s dark and the entire bottom of the satellite is in shadow. This means that the satellite will be several orders of magnitude weaker. “

“The orbit overcrowding problem is becoming an increasingly important focus in the space community, with concerns about the amount of debris in orbit around our planet.”

SpaceX has also adjusted the angle of the solar panels attached to the satellite so that the illuminated part is not visible from Earth. Combined, these fixes should more or less solve the problem of the operational Starlink satellites interfering with ground-based optical astronomy.

There are also some problems with the satellites interfering with radio astronomy. There may be a problem called frequency bleeding, in which satellites emit small amounts of radio waves at frequencies above their primary operating frequency, which can cause problems for radio astronomers. There is generally a lot of background noise that radio telescopes have to deal with, and satellite constellations can help.

SpaceX is working with the astronomical community in this area too, and astronomers seem largely optimistic that a solution can be found.

The final problem with launching a large number of satellites is not an easy one to fix. The orbital overcrowding problem is becoming an increasingly important focus in the space community, with concerns about the amount of debris in orbit around our planet. Space debris can be extremely dangerous, threatening everything from the International Space Station to our potential ability to inexpensively launch satellites in the future.

Space debrisTHE

The main approach to this problem has been for companies to ensure that they can responsibly desorb their satellites when they are no longer needed. If a Starlink satellite is nearing the end of its life or a satellite is faulty, disposal is relatively easy because the constellation is in low orbit. The satellites just need to be maneuvered into a lower orbit and they drop into the atmosphere and burn.

Other constellations may be in a higher orbit. In these cases, it is easier to send them into something called a cemetery orbit than it is to get them into the atmosphere. However, if a satellite fails in a higher object, it can stay there for a very long time. Some satellites are now being fitted with features like hooks that make it easier for another satellite to acquire and dispose of them.

The ugly: what kind of constellations does the future hold in store?

Hainaut stressed that SpaceX has made efforts well beyond its commitments to address issues Starlink has caused for the astronomical community and it is confident that these issues can be resolved. The problem is, given the increasing popularity of constellations and the arrival of more companies in the future, these new players will consider the night sky as well.

“[SpaceX is] They are really doing everything, beyond what they are legally obliged to do, to solve the problems, ”said Hainuat. “Astronomers have a very good working relationship with Starlink, but it’s not clear we will have the same relationship with others [companies]because it’s just a good will. “

Can other companies be trusted to follow SpaceX’s lead? There are contracts and agreements in place on the uses of space, including issues such as the disposal of satellites at the end of their lives. However, many experts argue that these contracts need to be strengthened and that there must be consequences for companies that fail to adhere to them.

“The problem is, there is no governing body that can really apply penalties consistently,” King said. “There are strict guidelines and contracts, but enforcement is problematic.”

Satellite constellations like Starlink can enable fantastic new leaps in telecommunications, but we need to find a way to balance that ability with the need to study the night sky and understand the universe beyond our planet.

“Space is a public community that we all share,” said King. “As a society, a lot has to be worked out as the constellations multiply … Everyone and nobody owns space and we all want to share it.”

Hyundai purchased Boston Dynamics for almost $ 1 billion – construct a run automobile now!

Reports surfaced early last November that Korean automaker Hyundai was in talks to buy Boston Dynamics, the company that makes these robot dogs that are likely to lead charges when the machines boot up.

Various reports have now confirmed that an agreement has been reached, and Hyundai will acquire Boston Dynamics from its current owner, the Japanese conglomerate SoftBank, for $ 921 million.

As Gizmodo reports, this is the third time in seven years that the unprofitable Boston Dynamics has changed hands.

The company was spun off from a research unit at the Massachusetts Institute of Technology in the 1990s and operated independently until it was purchased by Google in 2013. In 2017, SoftBank strengthened the company and took it from the Big G.

[Read: Why AI is the future of home security]

Under SoftBank, Boston Dynamics began selling its four-legged robot to select organizations and individuals to collect more data and test it in a variety of scenarios.

At this point, it’s largely impossible to say what Hyundai would like to do with Boston Dynamics. There is some overlap between companies that can lead to product refinements on both ends.

As CNET’s Road Show points out, Boston Dynamics not only makes four-legged harbingers of the apocalypse, but also industrial robots designed for use in warehouses.

Do you remember Handle, the two-wheeled box mover that moves just like an armless velociraptor in terms of elegance? Perhaps Hyundai would like to bring these things to its cars’ production lines.

While Hyundai is best known in the consumer world for making cars, that doesn’t stop there.

It has also developed a wearable robot that thinks of a more motorized exoskeleton to help people with lower extremity paralysis walk. Perhaps Hyundai could use Boston Dynamics technology to further develop these mobility tools.

Or maybe Hyundai wants to ditch Boston Dynamics’ sensor technology for self-driving or automated cars.

But let’s face it, assuming Hyundai doesn’t plan to take on the world with a fleet of robot dogs, we really want to see a walking car.

Back in 2019, Hyundai showed renders of its Elevate concept car at CES, which, as you guessed it, can drive and run.

In theory, it could function like a normal car, ride along and take care of its own business. Or the drivers could use their “legs”, lock the drive wheels and walk over rough terrain, just like the Boston Dynamics dog.

Coincidence? I do not believe that.

In September of this year, Top Gear reported that Hyundai is actively developing its running car, making it more than just a virtual concept.

This can be especially useful for emergency services who need to respond to disasters that normal wheeled vehicles cannot drive.

Hyundai’s “New Horizon’s Studio” is tasked with bringing this absolutely indispensable piece of technology to life. “We want to develop the world’s first vehicle in the transformer class,” said the then representative from Hyundai.

But I think we can all agree that absolutely, 100%, completely and completely everything it can must be devoted to this project. It has to be done.

Just like evil Overlords, Hyundai isn’t revealing its plans for Boston Dynamics, so we can’t know for sure if Elevate will become a reality.

The company’s global public relations director, Jin Cha, commented on a number of branches: “As a global company, Hyundai Motor is continuously exploring various investment and partnership opportunities. As a company policy, we do not comment on market speculation. “

Come on Hyundai, just do the walking car so we can at least fight the robot dogs in the war.

SHIFT is brought to you by Polestar. It’s time to accelerate the transition to sustainable mobility. That’s why Polestar combines electric driving with state-of-the-art design and exciting performance. Find out how.

NFL improves racial range however falls brief in some crew roles associated to racial and gender equality

Editor’s Note: Richard Lapchick is a human rights activist, racial equality pioneer, sports expert, scholar, and author. He is President of the Institute for Sports and Social Justice, Chairman of the DeVos Sports Business Management Program at the University of Central Florida, and Director of the Institute for Diversity and Ethics in Sport.

The National Football League’s Race and Gender Reports 2020 report, released Wednesday by the University of Central Florida’s Institute of Diversity and Ethics in Sports (TIDES), shows that while the NFL’s racial diversity continues to improve in certain categories, it continues to improve lag racial and gender equality in some key decision-making positions, particularly at team level.

When TIDES released the 2019 report card in October 2019, no one was prepared for the COVID-19 pandemic, the race bill, and the presidential election that would dominate 2020. In March and April, the world was locked in the early stages of the world pandemic. In May and June, a social and political outbreak exacerbated the already monumental year, supported by a polarizing presidential campaign that lasted until November. Up until that point, the words “social change” and “slowly” were considered inseparable. However, in the period between the 2019 and 2020 NFL Race and Gender Reports, we saw highly competitive change that accelerated in a year.

With the aim of raising awareness and reducing systemic racism, this national mobilization was supported and often led by sport. The largest mass demonstrations in American history included strong protests from athletes, bold initiatives from professional leagues, and huge financial pledges from teams, leagues, and athletes. Highlights included how the entire Jacksonville Jaguars organization marched into the local sheriff’s office during protests against police brutality in June. Many people disapproved of it when Colin Kaepernick first got on his knees in 2016. Now many sports fans support the activism of athletes against racism. Although promising, the sustainability of these efforts is not yet certain. The promise of change cannot satisfy us. It has to be lived.

Sport was a big changer. If it lives up to its ideals, it improves its platform. However, it can also be diminished if it does not live up to these ideals. The race and gender reports are a measure of this. The leagues’ support for player activism is another measure. The NFL obviously has a huge platform due to its historic fan base popularity.

TIDES noted that the NFL a B + For racist recruitment practices, the value rose significantly to 85.5% and was thus 3.2 percentage points above the previous year’s value of 82.3%. However, it is his C, At 73.0%, this was a decrease of 3 percentage points compared to the previous year. This gave the NFL a combined grade of a B-, at 79.2% a slight decrease compared to 79.3% in the previous year. It should be noted that this has been negatively impacted by the change this year to include a note for the CEO / President and for Team Vice Presidents. Without this change, there would have been an even bigger surge in the recruitment of races in 2020. Part of the decrease to 73.0 for recruiting practices is due to the change described above. The same applies to the overall grade of 79.2.

2 relatives

Even so, the NFL has seen improvements in several breed categories since last year’s report, such as: B. an increase from 10.9% to 13.9% for C-suite executives, 12.8% to 13.7% for team vice presidents and 28.0% to 30.5% for league office management . However, the under-representation of women and people of color in key decision-making positions at the team level remains an ongoing problem. For senior administration, the NFL achieved 23.9% compared to 24.4% in the previous year. Professional administration achieved 32.3% compared to 35.9% in the previous year. (The decline in gender grades has been a trend in professional sports for several years.)

For the second straight year, the NFL had just four color head coaches and only two color general managers at the start of the season. This is in stark contrast to the percentage of color players on the NFL rosters, which is 69.4%, and the record high of eight color head coaches and six color general managers just two years ago.

On a positive note, the Cleveland Browns announced in January the hiring of Andrew Berry as general manager and executive vice president of football operations, matching him with Chris Grier of the Miami Dolphins as the only two general managers of color in the NFL. Similarly, the Houston Texans and Atlanta Falcons sacked their head coaches and replaced them with black interim coaches through Week 6 of the NFL season. Bill O’Brien was replaced by Romeo Crennel in Houston and Dan Quinn in Atlanta by Raheem Morris. It’s worth noting that the Morris-led Falcons are 4-3 after starting 5-0 under Quinn and the Texans, led by Crennel, are 4-4 after starting 4-4 ​​under O’Brien.

There is reason to be optimistic. Strong anti-racist protests led by players during Race Settlement, standard-setting hiring initiatives set up by the league office, and pioneering attitudes in cities like Washington, DC have paved a clear path for the NFL to improve.

Notable in 2020 were two groundbreaking hires by the Washington Football team. Jason Wright became the first black team president in NFL history. Washington also hired Jennifer King as the first black assistant coach in NFL history.

King’s hiring is testament to the NFL’s annual Women’s Careers in Football Forum, run by Samantha Rapoport. Despite its inception just four years ago, 118 women were hired through the program in 2017, including 15 who were hired by teams this season. Last year’s forum was held at the NFL Scouting Combine, just weeks before the pandemic forced a global shutdown. It’s important that the NFL find a way to refresh the forum for its fifth year in 2021, even if it’s virtual.

The league office headed by the commissioner was a bright spot in the report and comprised two large employees of colored people. The League hired Dasha Smith as chief people officer late last year, and she was recently promoted to chief administration officer. The league also named Jonathan Beane Senior Vice President and Chief Diversity and Inclusion Officer.

While these new hires underscore the league office’s focus on improving diversity and inclusion, the challenge of getting involved at the team level has long been felt. A reassessment and revision of existing policies, including the Rooney Rule, were required.

The guidelines were revised in November 2020, when a proposal from NFL membership teams developing colored people for the positions of primary football manager, general manager or head coach presented a compensation draft for the selection of drafts in the third round . If one of these colored and / or female candidates moves to the position of primary football manager or head coach, a team will be compensated with a future draft for the third round.

According to the Rooney rule, the clubs must now interview at least two external color candidates for vacancies as head coach, at least one color candidate for one of the three vacancies as coordinator and at least one external color candidate for a senior football company or general manager position. In addition, the Rooney Rule applies for the first time to a number of managerial positions as clubs must include candidates for colored and / or female applicants in the interview processes for high-level front office positions such as club presidents and officers in communication, Finance, human resources, law, football, sales, marketing, sponsorship, information technology and security.

It’s also worth noting that the NFL updated its media policy in 2020, which has resulted in more visibility and better career advancement for paints assistant coaches. The new policy requires clubs to provide regular and appropriate access to assistant coaches – coordinators / co-head coaches and all senior position coaches – through their public relations departments for media interviews that serve the best interests of the club and the league.

These changes have taken the Rooney Rule a long way since it was passed in 2003 when teams had to interview at least one color candidate for head coaching positions. However, it is evident that these modifications are not a complete cure. As NFL top executive Troy Vincent said in a 2019 Forbes interview, “Diversity is a fact. Inclusion is a choice.”

Between the Rooney Rule and several development programs, there is no longer any question of whether adequate procedures exist to encourage upward mobility of color candidates. These programs include the Bill Walsh Diversity Coaching Fellowship Program founded in 1987, the Fritz Pollard Alliance Partnership founded in 2003, the Nunn-Wooten Scouting Fellowship founded in 2015, and the Quarterback Coaching Summit, first held in 2018.

With the talent pool of qualified and diverse candidates present, it may be time that everyone realized that having an adequate talent pool of qualified color candidates may never have been the problem.

Perhaps the root of the problem was never down and more likely up. Hopefully the changes made this year at the team level and to the top.

Both Troy Vincent and Jonathan Beane shared their belief that this comprehensive approach will result in lasting real change. Beane told me, “The focus on head coaches, managers and owners gets the most attention, but it is very important to know that these diversity and inclusion efforts apply to all areas of the league: our people, the executive team. In order to promote diversity, equity and inclusion across the NFL in a sustainable way, we have developed a strategic plan that focuses on data so that we can see where the opportunities are. and to make sure we have a welcoming environment, in which everyone can be their authentic selves. We want to operationalize this work throughout the organization so that we can continue to grow and prosper as the best professional sports organization in the world. “

We’ve seen change can be real and quick after player activism surfaced this year with the passionate video message from NFL players to the league and commissioner. I am convinced that Commissioner Roger Goodell heard that message and was changed by it. With player activism turning to the hiring process, I am confident that the agenda will be brought even further to the fore.

I am confident of the changes that will be made in the coming year.

Residents love low-traffic neighborhoods — however are they right here to remain?

This article was originally published by Christopher Carey on Cities Today, the leading news platform on urban mobility and innovation, reaching an international audience of city leaders. For the latest updates follow Cities Today on Twitter, Facebook, LinkedIn, Instagram, and YouTube, or sign up for Cities Today News.

From Bogota to Bologna, the introduction of expanded pedestrian zones and pop-up cycle lanes has been a global trend during the pandemic, but with traffic levels rising and pushback from some motorists, are repurposed streets here to stay?

In October, the UK’s Transport Secretary Grant Shapps told London’s borough councils he was “not prepared to tolerate” badly designed road closures and new cycle lanes that impose “sweeping changes” to entire communities.

“No one should be in doubt about our support for motorists,” Shapps warned a stark reminder to those who have championed healthy street initiatives over the past six months.

London’s schemes, which sprung up across the city over the summer months after a £250 million (US$330 million) government funding boost, have included wider pavements, pop-up cycle lanes, and low-traffic neighborhoods (LTNs) where some residential streets are blocked to motor traffic.

The temporary measures have been introduced to help facilitate social distancing on streets and make walking and cycling a safer and more attractive option for trips previously made on public transport or by car.

While welcomed by most, some of the measures have proved highly controversial in parts of the UK capital, with local councils facing street protests from residents and in some cases attacks on city property.

Pushback

LTNs, which are characterized by giant planter pots and bollards strategically placed on roads in residential neighborhoods to restrict or block traffic, have been a particular sticking point for some residents.

“You have to be incredibly careful about imposing measures on local communities,” Lambeth Councillor Tim Briggs said.

Briggs, a member of the London council’s Overview and Scrutiny Committee, is currently campaigning for the removal of his borough’s LTN, saying the lack of consultation is one of the main reasons for local opposition.

“I’m all for cycling and walking. For me, it’s the way it’s being implemented that is the issue.

“Councils shouldn’t use the funding they are given by the central government to bring in schemes without consulting properly first. For me, bringing in a scheme and then asking people why they don’t like it is a ‘cart before horse’ way of doing it.”

In September, London’s Wandsworth council removed its LTNs less than one month after their introduction following a furious local backlash. The response from residents and concerns around access for emergency vehicles were cited as the main reasons for the withdrawal, with videos of ambulances and fire engines struggling to gain access seen across social media.

London’s Ambulance Service has since raised concerns regarding a number of LTNs, with a spokesperson saying: “Changes to road layouts, traffic management schemes and road closures all have the potential to impede our response to the most critically ill people and could delay life-saving treatments or conveyance to the nearest emergency department.”

Several other London councils have since backtracked on their LTNs, and others have delayed or postponed their introduction.

Catch 22?

London’s borough councils face difficult choices. Having received a mandate from the government to implement measures rapidly, most councils have adopted an ‘act first, talk later’ approach, particularly since the interventions are temporary (meaning they don’t technically require a public consultation) and give some scope for experimentation.

To add to councils’ headaches is the complicated patchwork of London’s road network, and its governance. Transport for London (TfL) operates the primary artery roads in the city, while each of the 32 local boroughs are responsible for secondary roads. This means that there could be two entirely separate schemes operating in tandem – a scenario which, at times, has caused chaos for motorists.

“It can lead to some insane situations,” said London’s Cycling and Walking Commissioner, Dr Will Norman, the man tasked by the mayor with facilitating TfL’s active travel initiatives.

“There’s a road I know where one lane is managed by one authority and the other lane by another. Obviously, both authorities have competing interests, so this leads to challenges around the overall strategic direction.”

Will Norman, London’s Cycling and Walking Commissioner

Along with local councils, TfL has been installing its own “Covid spaces” through its Streetscape program – primarily through cordoned-off and protected cycle lanes on main roads.

But the disruption to motorists on these roads has meant that ‘rat-running’ – where motorists use residential side streets to avoid congestion – has become more frequent.

The addition of LTNs for residential streets, which are in part designed to prevent rat-running, has led to serious traffic chokepoints along some of London’s main arterial roads, as drivers face a double whammy of restrictions.

The bigger picture

Despite the negative headlines and council U-turns, Norman remains optimistic about the future. “Over the past five months, 92 LTNs have been delivered across the city. There has been some pushback around a few of those, maybe seven or eight, but any change to any road will always take a bit of time to bed in.”

“While there is a noisy minority [opposed to the measures] they are, in every poll I’ve seen, in the minority.”

The statistics support his argument. An October YouGov poll – commissioned by Greenpeace –  found that where UK residents had opinions on LTNs, positive views were three times more likely.

Of the 2,027 surveyed, 57 percent were in favor of the new measures and 16 percent against, while 32 percent had no opinion.

When asked if LTNs and other temporary measures are here to stay, Norman said: “I think many of them are. Obviously, we’ll have to go through local consultations but the conversations I’ve had with Downing Street and the Department for Transport tell me there is a continued commitment to this.”

And despite his scolding of councils in October, Grant Shapps has been one of the most vocal proponents of active travel, consistently emphasizing its importance.

In May, he stressed the government would be “speeding up the cycling revolution, helping individuals become fitter and healthier, and reducing air pollution, which remains a hidden killer.”

Then in November, after announcing a further £175 million of funding for active travel schemes, Shapps told councils: “Very few changes to anything will command unanimous support, and we do not ask it for these schemes. But there is clear evidence that for all the controversy they can sometimes cause, ambitious cycling and walking schemes have significant, if quieter, majority support.”

The link between active travel, health, and Covid-19 is also something which has increasingly come to the forefront of policy in recent months.

Rachel White, Head of Public Affairs at Sustrans, a UK NGO focused on active travel, said: “We think it’s really important the vast majority of these temporary measures are made permanent — physical inactivity already costs the National Health Service over £1 billion a year.

“We also know people’s resilience to Covid-19 is increased when you’re more physically active, which in turn further reduces the burden on the health service.”

Success story

To date, the most successful LTNs in London have occurred in boroughs that had taken proactive steps to increase cycling and walking before the pandemic. In the London borough of Waltham Forest, LTNs have complimented its ‘mini-Holland’ initiative, which was established in 2015.

The scheme – which introduced segregated bike lanes on main roads and other interventions such as making certain streets access-only for motor vehicles while maintaining through-routes for bikes and giving priority to pedestrians – was deeply unpopular when first brought in, seeing similar protests that other London boroughs face today.

But the reversal in public opinion has been staggering. When work started on mini-Holland, 44 percent of residents were opposed. Just 1.7 percent of residents would scrap the scheme now, according to council surveys.

Research also found that after one year, people were, on average, walking and cycling for 41 minutes a week more than those living in other comparable areas.

The borough has also taken credit for being an early pioneer of the 15-minute city – an idea developed by Sorbonne professor Carlos Moreno which allows residents to meet the majority of their needs within a short walk or cycle from their home.

The concept gained international attention after the Mayor of Paris, Anne Hidalgo, embraced it as part of her 2020 re-election campaign.

The view stateside

In the US, where the car is king, low traffic streets have historically been something of an anomaly. However, the pandemic has produced some bold initiatives by cities trying to change this mentality. An October study of ‘safe street’ initiatives by traffic analytics firm Inrix found city density and the overall purpose of the schemes to be key factors in how much people are likely to use them.

The firm analyzed trillions of location-based data points across five US cities – Washington DC, New York, Minneapolis, Seattle, and Oakland – collecting data anonymously via GPS probes on roads, vehicle navigation systems, and other devices.

While the report did not draw conclusions on the successes of the schemes, Bob Pishue, a transportation analyst at Inrix, said the overall aims of each ‘safe’ or ‘slow’ street were crucial.

“The purpose of the street really matters. Whether it’s built specifically to increase walking and biking or for on-street dining and leisure.

“Looking at Manhattan, the densest part of New York, we saw very low levels of activity on new cycle lanes, primarily because people weren’t commuting, but further out, we saw activity pick up.”

The highest levels of activity were found in Seattle and Minneapolis’s initiatives, at 82 percent and 75 percent respectively, while in Manhattan activity levels were just 43 percent when compared to pre-pandemic levels.

Pishue noted that Seattle and Minneapolis had larger, better-connected networks of slow streets geared specifically towards recreation, rather than commuting.

Out of the five cities surveyed, Minneapolis – where officials designated over 25 kilometers of road for walking and biking as part of the city’s Stay Healthy Streets initiative – saw the largest increase in activity, with the usage of the restricted roads in July a third higher than pre-pandemic levels.

“A lot of this is tied to people’s desire to get outside. In Minneapolis, we often joke about people going into hibernation during the winter, and as the weather improves people awake from their slumber – our trails, lakes, and leisure spots are suddenly full,” Matthew Dyrdahl, Minneapolis’s Bicycle, and Pedestrian Coordinator, said.

“Based on this we partnered with the Minneapolis Parks and Recreation board and started thinking about what we wanted to achieve. One of those ideas was connecting city streets to the city’s park network.”

Despite withdrawing the scheme for the winter months, the city is planning to relaunch in spring.

“We are now considering how we can relaunch this initiative. We have a lot of these quick build safety improvements ready to go for the spring, so we’ll take what we have learned and apply that to future projects,” added Dyrdahl.

The future of healthy streets

While ‘safe,’ or ‘slow’ streets may yield positive environmental and health benefits, the role of the car is unlikely to be diminished overnight. Dramatic drops in car usage seen during the height of the pandemic have largely been reversed – or even surpassed – in most cities, and many people remain reluctant to use public transport. A recent report by UK automotive services group RAC found the pandemic may have set attitudes to public transport back by as much as two decades.

For the first time since 2002, fewer than half of drivers surveyed in its annual report (43 percent) said they would reduce car use even if train and bus services were improved – down from 5% in 2019.

It also found that more than half of UK drivers (5%) say having access to a car is more important now than it was before the pandemic.

“As cities seek to improve air quality and make urban centers cleaner places, it’s clear that low-cost, efficient alternatives to the car need further thinking and much greater financial investment,” said Rod Dennis, the RAC’s Data Insight Spokesperson.

“Even with lower traffic volumes, the pandemic appears to have reinforced the bond between drivers and their cars.”

Peter Ridd: It is science that is lazy, not the Nice Barrier Reef

Reposted by Paul Homewoods MANY PEOPLE DO NOT KNOW THAT

DECEMBER 7, 2020 Tags: Coral

By Paul Homewood

The International Union for Conservation of Nature has released its latest report on the condition of the Great Barrier Reef. It has turned the volume up one notch, claiming the threat to the reef has gone from “significant concern” to “critical”. It blames climate change, agriculture pollution, coastal development, industry, mining, shipping, overfishing, disease, problematic native species, and coal dust – you name it, it’s killing the reef.

However, the report is just a repetition of old, mostly false or misleading information produced by generally untrustworthy scientific institutions with an activist agenda and no commitment to quality assurance.

It is noteworthy that the world believes that one of its most pristine ecosystems is on its last legs. Part of the problem is that very few people visit the reef underwater and far from shore. The truth is hidden. Those of us in North Queensland who live next to the reef and tourists from elsewhere can report that the water is an iridescent clear blue and completely unpolluted. The fish and coral are fabulous.

The reef occasionally conspires to give the impression that it is dying. A coral area the size of Belgium can be killed by cyclones (hurricanes), native starfish plagues or bleaching. All of these events are completely natural and part of life on the reef. In fact, each of the 3,000 individual reefs along the entire 2,000 km length of the Great Barrier Reef is a 50 to 100 m high plateau of dead coral remnants that has built up over thousands of years. The living coral lives on the surface of this pile of dead ancestors.

Sixty years ago, when these cycles of death and destruction were first discovered by scientists, it was legitimate to worry about whether they were unnatural. But there is ample evidence now, almost completely ignored by the International Union for Conservation of Nature, that the reef is okay. The coral always recovers vigorously after severe mortality events. Corals are abundant on all 3,000 reefs. While the amount of coral varies dramatically from year to year, it is roughly the same today as it was when records began in the 1980s. Coral growth rates have not decreased – if at all, they have increased as one would expect given the slight increase in temperature over the past century. Corals like it hot and grow faster in warmer water.

Ignoring evidence of the reef’s apparently good condition is not the slightest problem with this IUCN report. Evidence that is obviously false is also used. For example, the report claims that blowing coal dust from ship loading facilities poses a risk to the reef that is 100 to 1000 km from the ports. This ridiculous claim is based on a report prepared by undisputed expert on the subject, Dr. Simon Apte and other scientists at CSIRO, who showed that the results were 3000 percent flawed. It is also highly doubtful that the original scientists actually measured coal dust. They measured polyaromatic hydrocarbons, which are common, naturally occurring molecules that are not specific to coal.

Unsurprisingly, the IUCN report made the mistake of using this discredited coal dust report. Other major Australian reports on the reef also cite it. It is noteworthy that Apte refused to do anything when they tried to get the scientific journal and the Australian Institute of Marine Science, which was responsible for the coal dust data, to correct the error. The scientific institutions are no longer trustworthy.

The IUCN makes other equally scandalous mistakes. It is claimed that despite all measurements showing pesticide concentrations so low that they are generally undetectable with the most sensitive scientific equipment, it is claimed that agricultural pollution is a problem. The effect of sludge washed from farms is also negligible.

The fundamental problem with the IUCN report is that it is based on scientific knowledge, the quality of which is poorly assured. The scientific foundations are lazy and none of the science organizations want to solve the problem – also because the science organizations and the IUCN have long since stopped being scientific. They recognized their political power. We have to recognize that they have become political.

Until true quality assurance measures can be put in place in reef science facilities, the problem of untrustworthy scientific evidence being reported and replicated ad nauseam will persist. The only good news is that the next IUCN report on the reef in 2023 won’t be any worse than “critical” as that seems like the worst category they have.

May an infinite atomic bomb destroy the planet?

Chris DeGraw / Digital Trends

One of the most classic tropes in science fiction is the insidious plan to destroy the planet with a massive bomb towards the end of the world. You’ve almost certainly seen it before. The Trope has appeared in some of the world’s most popular film franchises, from Mission Impossible to Planet of the Apes. Sometimes the bomb in question ends all life on Earth, but in other cases it is powerful enough to blow the entire planet to pieces.

The mere ubiquity of this troop begs the question: are weapons of this size and power possible in the real world? Sure, nuclear weapons are deadly and dangerous, but do they have a realistic doomsday potential? Could someone build a nuclear weapon big enough to wipe out the planet? What would it take To get an answer, Digital Trends spoke to Brian Toon, an atmospheric researcher at the University of Colorado Boulder whose research led to the discovery of nuclear winter.

According to Toon, it is helpful to think about the asteroid that killed the dinosaurs if you want to know what force it takes to blow up the planet. The energy released by this collision was equivalent to an explosion of 100 million megatons. Toon says the chance that we will ever build an atomic bomb this powerful is practically zero.

How can he be so sure? Well, the largest atomic bomb ever detonated, the Tsar Bomba of the Soviet Union, had a yield of only 50 megatons. That is more than 1,570 times more powerful than the bombs the US dropped on Hiroshima and Nagasaki together. And while the explosion that caused Tsar Bomba was the largest human-made explosion in history, it was still only 0.0000001 percent as powerful as the asteroid that killed the dinosaurs.

Even if we could cobble together enough fissile material to create a bomb with the same destructive power as the asteroid mentioned above, it wouldn’t be enough to destroy the planet. “The asteroid that killed the dinosaurs didn’t do anything to orbit or blow up the earth,” says Toon. “It made a hole in the Yucatán Peninsula and covered parts of the United States with a pile of stones from the crater and [exterminated] A fair fraction of all the species on the planet, but it didn’t do anything serious to the planet itself. “

Not so sure of destruction

So apparently we can’t blow up the earth with a massive atomic bomb – but could we destroy the planet in any other way with such a bomb? Another popular movie proposition is that nuclear war leads to what is known as a nuclear winter. That’s the idea of ​​nuclear explosions that inject soot into the stratosphere and block the sun. Could a massive bomb do this all by itself?

According to Toon, the answer is no. One large bomb would not be enough to cause a nuclear winter. He says that for a nuclear winter to take place, dozens of bombs would have to be dropped in cities around the world at around the same time. Even if you were to completely decimate one of the largest cities in the world, it wouldn’t create enough soot to cause a nuclear winter.

“Toon says setting the Earth’s atmosphere on fire before the first atomic bomb exploded was a serious problem.”

“If you want a nuclear winter, you have to burn a lot of material, mostly in cities,” says Toon. “It’s a bit difficult to quantify, but it’s believed that if you used typical sized nuclear weapons in 100 cities – major cities – you would likely create a nuclear winter.”

So a nuclear winter with a single bomb is unlikely – but how about setting the earth’s atmosphere on fire like the bomb on the planet of the apes supposedly could? Surely a huge bomb could do that, right? As it turns out, that’s not particularly likely either.

Toon said setting the earth’s atmosphere on fire before the first atomic bomb exploded was a serious problem. At the time, physicists feared that detonating the bomb could start a chain reaction that would set the atmosphere on fire, but they decided to test the bomb anyway.

“People feared it would start a chain reaction in the atmosphere – a fusion reaction – and basically burn all the water on the planet and destroy the earth,” says Toon. “They needed to know how likely it was that the atoms in the atmosphere were actually absorbing the particles that came from the fusion reaction, and they weren’t 100 percent sure what it was, but someone said there was a one-in One – million chance of destroying the entire planet. “

According to Toon, these physicists decided that a million chance is worth the risk and they set the bomb off. This explosion did not set the Earth’s atmosphere on fire, nor did the many atomic bombs we have fired since then. So it seems pretty unlikely that our theoretical super bomb would do this.

What Toon fears about atomic bombs is less extravagant, but very dangerous. He says both the United States and Russia have worked to improve their nuclear weapons capabilities in recent years, and we could be approaching another arms race if things escalate further.

“It could become one, and it would be very expensive and worthless if you didn’t happen to be someone who works for companies that make weapons,” says Toon.

How AI will fully remodel training

Alistair Berg / Getty Images

Nothing seemed strange about the new teaching assistant, Jill Watson, who briefed students on assignments and due dates in Professor Ashok Goel’s Artificial Intelligence class at the Georgia Institute of Technology. Her answers were brief but informative, and it wasn’t until the end of the semester that students learned that Jill wasn’t a “she” at all, let alone a human. Jill was a chatbot built by Goel to offload his eight other human TAs.

“We thought that if an AI TA would automatically answer routine questions that usually have clear answers, the (human) teaching staff could win the students over to the more open questions,” Goel told Digital Trends. “It wasn’t until later that we were motivated by the goal of building human-like KI-TAs so that students couldn’t easily tell the difference between human and KI-TAs. Now we are interested in developing KI-TAs that will improve student engagement, retention, performance and learning. “

AI will change both the face and the function of education.

AI is quickly integrating into every aspect of our lives and like the students in Goel’s class, we are not always aware when we are dealing with it. However, the impact of AI on education will become apparent in the years to come as these systems make their way into classrooms everywhere.

Like computers and the internet, AI will change both the face and function – the what, why and how – of education. Many students are taught by bots instead of teachers. Intelligent systems advise, teach and grade tasks. In the meantime, the courses themselves will change radically as educators prepare students for a job market where millions of roles have been machine-automated.

AI-powered education may sound like something from the distant future, but it is already a topic of interest to both academics and businesses. AI-powered educational toys have flooded the market in recent years, many of them through crowdfunding platforms like Kickstarter and Indiegogo, where they often exceed their financial goals.

Professor Einstein, for example, teaches science kids with goofy facial expressions and a German robotic lilt. The company’s Kickstarter campaign, developed by Hanson Robotics and supported by Watson from IBM, raised nearly $ 113,000. Meanwhile, the startup Elemental Path is offering CogniToys, a range of educational intelligent dinosaurs designed to play games, have conversations, and help kids learn to spell. Their Kickstarter campaign raised a whopping $ 275,000 from backers in 2015.

“Big things are on the agenda for AI-powered educational toys,” Danny Friedman, director of curriculum and experience at Elemental Path, told Digital Trends. “I use them in every classroom as a complementary learning tool that is not only built into a teacher’s curriculum, but also tied to a student’s personalized data such as preferred learning methods and areas of interest. I also put them in every home, not just to answer questions, but also to encourage pro-social interactions. AI-powered toys will be just as ubiquitous in households as the cell phone. “

“Big things are on the agenda for AI-powered educational toys.”

A student’s engagement with AI only increases as they progress through the school system. Educational AI toys are being replaced by tutors, whose job it is to identify weak points and enable additional training.

Teachers are relieved of the simple task of grading papers in subjects ranging from natural sciences to social sciences. Systems like Wolfram Alpha can already answer complex math equations and questions in a language that is informative and accessible. Integrating such an engine into an automated rating system – especially with quantitative problems – would be a breeze. The educators will be happy to be able to focus on the more personal aspects of the education.

“When it comes to AI in teaching and learning, many of the more routine academic tasks (and those that are least rewarding for faculty) such as B. the grading of tasks can be automated, “write the researchers Mark Dodgson, director of the technology and innovation management center. University of Queensland Business School and David Gann, Vice President of Imperial College, in a report on AI and higher education for the World Economic Forum.

Pepper, a multipurpose human robot design from Softbank, is the first humanoid robot to be used in Japanese households.

Once a student reaches high school, she may well be entering freshman next to what AI education experts on a Pearson report refer to as a “Lifelong Learning Companion”. For the past nine years, this digital companion would have accompanied her in class, helped her with her homework and learned with her.

The learning partner – who may manifest as a robotic T-Rex, or more likely something more subtle like a smartphone application – even acted as a student on occasion, so the human student could teach them what they learned and deepen their knowledge.

“This companion would be accessible to the entire student [his or her education]”Wayne Holmes, co-author of the Pearson report and lecturer at the Open University’s Institute of Educational Technology, told Digital Trends.” It could always indicate that they are doing or helping them with work that is difficult for them It will also provide information for the teacher to engage. The idea is that over time the tutor can create this profile of the individual that can be used to assist them in their further development. “

These digital learning partners should support rather than replace teachers, emphasized Holmes. In fact, he expects educators to have their own AI assistants to make their jobs easier and more effective.

These digital learning partners are designed to support rather than replace teachers.

“Teachers would have their own companion, they would be their own AI teaching assistant,” he said, adding that a student’s companion and a teacher’s AI assistant would “communicate so that the teaching assistant knows what is going on with the profile of the individual student is going on and would be able to interact with it. “

When a student enrolls in a university, she will be, if you will, the product of two “heads”: the AI ​​in her brain and the AI ​​she developed as a learning partner. And at the university itself, AI will be everywhere – as TAs in the classroom, as support in the enrollment office, and even as academic advisors. This year the Technische Universität Berlin used a chatbot called Alex to help students plan their course calendar.

“I think the advantages of the chatbot system lie in the completeness and availability of the information,” said Thilo Michael, currently a doctoral student at TU Berlin, who designed the system as part of his master’s degree. “The chatbot tries to translate students’ questions into searchable queries just like a human advisor would, but has all the information available at once. Human advisors would have to search various online systems and might even provide incomplete information. “

Michael emphasized that the system is not intended to replace people. “The system is able to answer pragmatic questions about the courses and majors available, but it cannot answer questions on a broader level,” he said. “I think the system could very well be used in combination with advice to have the best of both worlds.”

Outside of traditional learning institutions, AI has the potential to make education accessible to more people. In developing regions where there are few teachers, a robust AI system can be used to teach students with minimal or no involvement of a human educator.

The XPrize Foundation, which develops Moonshot competitions to promote “Radical Breakthroughs for the Good of Humanity,” provides the team that will create the best basic learning application that can replace a teacher for children with access to a tablet but not a human currently US $ 10 million to educators. In June, XPrize selected eleven semi-finalists from nearly 200 teams to compete in the Global Learning competition. It is likely that the winning system will be assisted by the AI ​​to offer more personalized and dynamic lessons.

Still, there is no shortage of ethical issues that need to be addressed before AI is fully implemented in education, something Holmes and his colleagues are quick to recognize. For one, educators need to take into account the privacy and confidentiality of the data collected, especially when that data relates to children. For example, who does the information belong to? And who will have access to it?

“There is no obvious answer to this problem, but it is an issue that needs to be addressed,” said Holmes.

And before psychologists educate a generation with AI tutors, they should understand its developmental implications. Do students become addicted to technology? And what happens if the system works incorrectly or fails? Similar difficult questions, but those that are worth answering for the future of our greatest resource – the minds of the next generation of humanity.
