EU to carry again on China tech funding ban — for now

The day following US President Biden’s unveiling of an executive order designed to curb investments in certain tech sectors in China has been marked by tentative reactions from both policymakers and the business community. 

The UK government stated early on Wednesday that the decision provided “clarity” on the approach of its close ally. Furthermore, it said it would “consider these new measures closely” as it continued to evaluate any potential implications for national security. 

Meanwhile, the European Union was only marginally less ambiguous in its response. Later in the afternoon, the Commission said that it was “in close contact” with the White House. However, there was no indication that the bloc was looking to emulate the same measures any time soon. 

“We will be analysing the Executive Order closely,” the Commission said in a statement shared with Reuters. “We are in close contact with the US administration and look forward to continued cooperation on this topic.”

It further added it recognised the significance of the topic, and that the EU and its member states have a common interest in preventing capital and expertise from fueling military and intelligence capabilities of “actors who may use them to undermine international peace and security.” 

Balancing technological trade act

Brussels has been exploring its own ways to constrain flow of technology to China, adopting an economic security control with stronger export controls in June. However, with China constituting the EU’s largest trading partner, it is a tricky field to navigate. 

If the past years of back-and-forth over semiconductor technology have demonstrated anything, it is Beijing’s readiness to retaliate against what it perceives as “technological bullying.” China’s restrictions on rare earth exports threaten to derail not only the nascent chipmaking industry in Europe, but even the EU’s green transition as a whole. 

Markets do not seem to have been especially perturbed by the executive order, which bans new private-equity, venture-capital, and joint-venture investments in advanced semiconductors and microelectronics, quantum technology, and certain AI systems. 

Still, US investors have raised concerns specifically about a potential payback response from China. Indeed, the EU may choose to hold off on any concrete measures, waiting to see what the fallout of the latest move of the US in its complicated relationship to China will be.

Biden-backed electrical automobile firm recordsdata for chapter • Watts Up With That?

From NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Another Solyndra!

President Biden frequently extolled an electric vehicle company — in which his energy secretary heavily invested — before it declared bankruptcy on Monday.

Bay Area-based electric bus and battery maker Proterra filed for Chapter 11, with CEO Gareth Joyce citing “various market and macroeconomic headwinds that have impacted our ability to efficiently scale.”

The EV firm, which sold more than 1,300 electric buses to public transit systems in the US and Canada, was valued at $1.6 billion when Biden, 80, took office in January 2021 — but closed with a market value of $362 million, according to Reuters.

In 2021, the president pledged more than $10 billion from his $1.9 trillion bipartisan infrastructure plan toward zero-emission transit and school bus programs.

He has promoted Proterra several times since taking office, and once virtually toured a facility.

Energy Secretary Jennifer Granholm raked in $1.6 million in profit after selling hundreds of thousands of shares in May 2021, months after she had first pledged to do so.

“Right now we’re running way behind China, but you guys are getting us in the game,” Biden said in April 2021. “We’re going to end up owning the future, I think, if we keep doing what we’re doing.”

At the time of the tour, Energy Secretary Jennifer Granholm held between $1 million and $5 million in stock of the electric vehicle company, The Washington Free Beacon reported, prompting ethics concerns and calls for her divestment.

Granholm raked in $1.6 million in profit after selling hundreds of thousands of shares in May 2021, months after she had first pledged to do so. She served on Proterra’s board from February 2017 until just before her Senate confirmation hearing in January 2021.

Philadelphia purchased a fleet of Proterra buses in 2019 that had to be taken out of service in February of the following year due to defects, the local National Public Radio affiliate reported.

According to WHYY, sources familiar with the situation blamed a defect in the buses’ plastic chassis that led to cracking.

10 medicine which might be probably targets for fall Medicare worth negotiations

Merck & Co. Inc.’s Januvia brand medication, used to treat Type 2 diabetes.

Medicare is poised to directly negotiate drug prices with the pharmaceutical industry this fall for the first time in the program’s nearly six-decade history.

The Centers for Medicare and Medicaid Services will unveil, no later than Sept. 1, the list of 10 drugs that it is targeting this year, an agency spokesperson said.

Though it is still unclear which 10 drugs Medicare will select, several pharmaceutical companies have already revealed in court filings that they expect four of their blockbuster medications to be targeted.

Merck‘s lawyers said the company’s Type 2 diabetes drug Januvia will be on the list, with its blockbuster cancer immune therapy treatment Keytruda to become a target in subsequent years.

Bristol-Myers Squibb and Johnson & Johnson, in separate filings, said their blood thinners Eliquis and Xarelto will be subject to the negotiations this year. Abbvie said in its own filing that the company expects its blood cancer drug Imbruvica will also be a target in the fall.

These are the other six drugs that will likely be subject to negotiations this year, according to an analysis by the Journal of Managed Care and Specialty Pharmacy published in March:

  • Jardiance, made by Boehringer Ingelheim, used to treat heart failure
  • Enbrel, made by Amgen, used to treat rheumatoid arthritis
  • Symbicort, made by AstraZeneca, used to treat asthma
  • Ibrance, made by Pfizer, used to treat breast cancer
  • Xtandi, made by Astellas Pharma, used to treat prostate cancer
  • Breo Ellipta, made by GSK, used to manage pulmonary disease

Surge in list prices

The historic negotiations, established by the Inflation Reduction Act, are the cornerstone of the Biden administration’s efforts to slash drug costs.

The list price of Medicare’s top 25 drugs has more than tripled on average since they first entered the U.S. market, greatly exceeding the rate of inflation, according to an analysis published by AARP on Thursday.

AARP is a powerful lobbying group that advocates on behalf of people ages 50 and older. The group strongly supports the Medicare drug-price negotiation program.

The list price of Januvia has surged 275% since 2006, according to the AARP. Eliquis has jumped 124% since 2012. Xarelto has increased 168% since 2011, and Imbruvica has risen 108% since 2013.

These price hikes were all significantly higher than the corresponding rate of inflation, which ranged from 31% in the case of Eliquis to 50% in the case of Januvia, according to AARP.

Merck booked $2.8 billion in revenue from Januvia in 2022. Bristol Myers Squibb generated $11.8 billion in sales from Eliquis last year. Johnson & Johnson reported $2.47 billion in revenue from Xarelto. And Abbvie posted $4.6 billion in sales of Imbruvica.

People enrolled in Medicare take an average of four to five prescription drugs a month and increasingly face out-of-pocket costs that many struggle to afford, according to AARP.

“More and more people face cost-sharing that is directly affected by drug price increases,” Leigh Purvis, who analyzes health-care costs for AARP, told reporters on a call Thursday.

One in 5 older adults cope with high drug prices by not filling a prescription or by skipping a dose to save money, according to a study published in Jama Network Open in May.

The industry lobby group Pharmaceutical Research and Manufacturers of America, or PhRMA for short, criticized AARP for using drug list prices in their analysis.

The list price is set by manufacturers before discounts and rebates on medications are taken into account. PhRMA said net prices, which take these discounts into account, are 50% lower than the list prices for brand medications on average. Net prices for brand medicines have been below or in line with the rate of inflation for the past five years, according to PhRMA.

Industry aims to block negotiations

The pharmaceutical industry has filed a torrent of lawsuits to block the negotiations, arguing that the program is an unconstitutional seizure of their property. Drugmakers view the negotiations as a major threat to their profits and argue it will jeopardize future drug development.

Bristol Myers Squibb, Johnson & Johnson, Merck, the U.S. Chamber of Commerce, and the lobby group Pharmaceutical Research and Manufacturers of America have all sued in separate federal district courts.

Legal experts say the companies are spreading their lawsuits across the country to increase the chances that one of the cases will ultimately end up before the Supreme Court.

While the list of 10 drugs will be published by September, there’s growing uncertainty over whether the negotiations will move forward on schedule.

The U.S. Chamber of Commerce has asked a federal judge in Ohio to block the program before Oct. 1. Kelly Bagby, vice president of AARP’s legal team, said the chamber faces a heavy lift to convince the judge that its interests outweigh those of Medicare beneficiaries.

“It’s so obvious that the pharmaceutical companies are not the victims that they are painting themselves to be,” Bagby said on Thursday’s call.

“We are trying to protect the integrity of the Medicare program for everybody,” she said. “But we are also trying to allow for older people and vulnerable people to not have to make horrible choices — do I get to pay my rent today or do I get to take my lifesaving drugs.”

A spokesperson for PhRMA, the industry group, accused AARP of overlooking the role that insurers and pharmacy benefit managers play in rising drug costs.

After the list of drugs is published, the manufacturers have to sign agreements to participate in the negotiations by Oct. 1. CMS will then make an initial price offer to the companies in February 2024. The manufacturers then have a month to make a counteroffer.

The negotiations end in August 2024, with prices published the following month. The reduced prices go into effect in January 2026.

Deploying a Large Antenna On The Moon May Research Its Insides

Understanding what lies under the lunar surface could be critical to future exploration efforts. A series of missions have already mapped some parts of the sub-surface of the Moon. Still, few have delved deep inside, where large lava caverns or potentially valuable water or mineral deposits may lie. But that might be about to change. NASA’s Institute for Advanced Concepts (NIAC) supplied funding to a novel technology developed by a team at its Jet Propulsion Laboratory (JPL) that could solve the long-standing problem of seeing what lies within the Moon.

The project, the Passively Expanding Dipole Array for Lunar Sounding (or PEDALS), uses a self-deploying technique to position a large-scale antenna on the lunar surface. Once deployed, it can collect data on the lunar sub-surface down to a few kilometers, comparable with the deepest data we have ever collected.

Currently, the deepest data was collected by the Lunar Radar Sounder on the SELENE orbiter (better known as the Kayuga). However, it was intentionally crashed into the Moon back in 2009, and, despite being able to monitor signals up to 5 km deep, it did not provide anything resembling a high-resolution image.

Lava tubes are one of the most intriguing parts of the lunar sub-surface. Fraser explains them here.

Other sounds, some of which date back as far as the later Apollo Missions, had a higher resolution but could reach the depth that would unlock a better understanding of the lunar surface’s structure. A presentation created by the JPL team notes five scientific objectives that can be solved by PEDALS, ranging from mapping the 3D interfaces of volcanoes to understanding rock density in a particular area.

So just how would the system achieve those objectives? PEDALS would land using the time-honored tradition of falling to the surface in an airbag. Once there, it will deploy a coilable boom, a concept that has been the focus of several years of NASA research already. In theory, there’s no actual constraint to the size of the boom PEDALS deploys, but the volume of the landing airbag and the surface area the antenna will need to cover will have an impact.

After deployment, PEDALS collects data using its antenna. What that antenna would look like remains a point of study, as the presentation details two potential configurations – a loop antenna or a coupled dipole. Both have advantages and disadvantages, but the JPL team needs to do more research to determine which would be more useful for the lunar use case.

Lava tubes are especially interesting on the Moon.

One obvious question is – where could you deploy this thing? Passive viewing of the Apollo missions shows that the Moon isn’t particularly flat, and massive boulders are randomly strewn. Calculating the large rock sizes (they estimate 50 cm max diameter) and how much room they would need to deploy to a field with many times the area of the deployed antenna as a “free path,” according to the JPL report.

That’s not necessarily a deal breaker, as there are areas on the Moon that meet the criteria – and maybe in a best-case scenario, they could get some help from an autonomous rover to move some of the rocks out of the way. But for now, the idea appears to be on hold, as it is unclear if PEDALS received a Phase II grant after being funded in 2021. However, it’s likely that deploying a large-scale antenna to the lunar surface will someday get its day in the Sun.

Supply — Florida State amongst four ACC faculties in opposition to including Cal, Stanford

  • Andrea Adelson, ESPN Senior WriterAug 11, 2023, 08:08 PM ET

    Close

    • ACC reporter.
    • Joined ESPN.com in 2010.
    • Graduate of the University of Florida.

Four ACC schools are opposed to adding Cal and Stanford, a source confirmed to ESPN, but expansion discussions are not completely over as of Friday evening.

Though there is no call currently scheduled for the presidents to talk about expansion again, the discussions continue in the hopes that perhaps they can get to 12 “yes” votes, the required number to add teams. Florida State, North Carolina, Clemson and NC State are opposed, a source said, confirming news first reported by Sports Illustrated.

One source described the expansion discussion as being “on life support,” two days after ESPN reported the talks among the presidents hit “significant roadblocks” following a call among presidents on Wednesday night.

Multiple sources indicated there is no deadline to make any decision for the ACC, and a presidents call could be scheduled at any time. A vote will be taken only if there are enough yes votes. One source believed a decision should have been made during the Wednesday call: “I would imagine that there’s not much more for them to discuss. I would think that the next item on the agenda is to make a decision.”

It should be noted the four schools that are opposed are among a group of seven schools that have had separate discussions among themselves looking at the ACC grant of rights and a path forward. The ACC grant of rights ties the league together through the end of its television contract with ESPN in 2036 and gives the conference control over member school’s media revenue and broadcast rights.

For Cal and Stanford, the clock is ticking as they evaluate their future options.

There is appeal among a majority of the presidents to add Cal and Stanford from an academic and Olympic sports perspective. There is not nearly as much appeal among athletics directors, however, for a host of reasons, including football, finances and West Coast travel.

The ACC is facing a $30 million annual revenue gap with the SEC and Big Ten, and the priority for athletics directors in the league is to try to significantly enhance revenue in the league. The ACC has looked at expansion options over the past two years but has not added any schools because they do not enhance the conference’s financial situation.

That is also the case with Cal and Stanford. Neither school would add to the financial bottom line, sources indicated. But there is another component at play here that might be more appealing than finances. With Florida State president Richard McCullough telling his board of trustees last week the university would have to “very seriously” consider leaving the ACC unless there is a radical change to the conference’s revenue distribution model, adding schools could help solidify the conference into the future.

Any team that wants to leave the ACC for next season must notify the league by Aug. 15. Perhaps that is why talks are not completely over, as there continues to be a waiting game to see what Florida State does. Though multiple sources indicated it appears unlikely the Seminoles will do anything by Aug. 15, there is a bit of a guessing game involved in what could happen.

With the prospect of adding no schools on the table, and understanding Florida State is serious about leaving, perhaps the Seminoles open more doors to getting what they want — a change in the way television revenue is distributed. Or perhaps their vocalness will not change anything. More clarity is expected once the deadline passes.

SEC investigating Illumina over Grail acquisition

A building on the campus at the world headquarters of Illumina is shown in San Diego, California, September 1, 2021.

Mike Blake | Reuters

The Securities and Exchange Commission is investigating Illumina over its controversial $7.1 billion acquisition of cancer test developer Grail, the DNA sequencing company said in a securities filing late Thursday. 

Last month, the SEC informed Illumina about the probe and requested documents and communications related to the deal. The agency also asked for statements and disclosures about the “conduct and compensation” of certain members of both Illumina and Grail’s management, according to the filing. 

Illumina, in the filing, said it is cooperating with the SEC. An agency spokesperson did not immediately respond to CNBC’s request for comment on the investigation. 

Shares of Illumina fell about 4% on Friday. 

The SEC’s probe only puts more pressure on Illumina, which has lost great sums of money since closing the deal in August 2021. The company’s market value has fallen to roughly $28 billion from around $75 billion the month the deal closed. 

Illumina’s Grail deal has also faced heavy scrutiny from antitrust regulators in the U.S. and European Union. 

The European Commission, the EU’s executive body, fined Illumina a record $476 million last month for closing the acquisition without first securing regulatory approval. 

The fine came after the commission blocked the deal in September over concerns it would stifle innovation and consumer choice in the emerging market for cancer detection tests. 

Illumina has appealed the European Commission’s decision, arguing that the body lacks jurisdiction to block the merger between the two U.S. companies. 

Illumina expects a final decision on an appeal in late 2023 or early 2024. That’s also when the company anticipates it will hear an outcome of its appeal of a similar order by the U.S. Federal Trade Commission. 

Illumina has said it will divest Grail if it loses either appeal. 

Illumina’s determination to keep Grail sparked a heated proxy showdown with activist investor Carl Icahn, who holds a 1.4% stake in the company. Much of Icahn’s opposition stemmed from Illumina’s decision to close the acquisition without gaining approval from antitrust regulators.

Illumina believes it can expand the availability, affordability and profitability of Grail’s Galleri test, which can screen for more than 50 types of cancers through a single blood draw.

UK’s promise to guard encryption is ‘delusional,’ say critics

The British government’s promise to protect encryption has been pilloried by security experts and libertarians.

The dispute stems from a section of the Online Safety Bill. Under the legislation, messaging apps would be forced to provide access to private communications when requested by the regulator Ofcom.

Proponents say the measures will combat child abuse, but critics are aghast about the threat to privacy. They fear the plans will facilitate mass surveillance and damage the UK’s tech sector. Signal, Whatsapp, and five other messaging apps have all threatened to leave the country if the law is passed.

The British government has sought to allay their concerns. On Thursday, technology minister Michelle Donelan said the government is “not anti-encryption” and will protect user privacy.

The <3 of EU tech

“Technology is in development to enable you to have encryption as well as to be able to access this particular information, and the safety mechanism that we have is very explicit that this can only be used for child exploitation and abuse,” Donelan told the BBC.

Her remarks were quickly lambasted by critics. Matthew Hodgson, CEO of secure messaging app Element — which is used by the government’s own Ministry of Defense — described Donelan’s claims as “factually incorrect.”

“No technology exists which allows encryption AND access to ‘this particular information.’ Detecting illegal content means ALL content must be scanned in the first place,” he said.

In response to these concerns, the government’s cybersecurity chiefs argue they can protect both children and privacy. To do this, they propose using client-side scanning, which involves installing software that detects suspicious activity. Many experts, however, argue that this tech is impossible to build.

“You cannot turn scanning on and off,” Hodgson said. “The government still does not understand how technology or encryption works, despite numerous experts explaining this to them.

“Its own ‘Safety Tech Challenge Fund’ failed to deliver an impossible solution to scan messages without breaking encryption. What more will it take for the government to finally accept how encryption works?”

Tech firms are not alone in opposing the plans.  Civil rights groups and libertarians have also denounced Donelan’s comments.

Michelle Donelan was appointed Secretary of State for Science, Innovation and Technology on Thursday 20 July.Michelle Donelan was appointed to lead the new department for science, innovation, and technology in February.

Matthew Lesh, director of public policy and communications at the IEA, a free-market think-tank, described the government’s claims as “delusional.”

“There is no magic technological solution in existence or development that can protect user privacy while scanning their messages,” he said. “It’s a contradiction in terms.”

These arguments, however, have struggled to convince the general public.

According to a recent YouGov survey, there is strong support for the government’s plans. Almost three-quarters (73%) of respondents backed the requirement for tech that can identify child abuse in encrypted messages.

The NSPCC — which commissioned the research — said the critics are “out of step” with the public on the issue.

Defenders of encryption are running out of time to win more hearts and minds. The Online Safety Bill is expected to become law later this autumn.

Biden Says Victims Of Maui Wildfires Will ‘Get Assist Instantly’

As the death toll from the fires tearing through the Hawaiian island of Maui rises, President Joe Biden is announcing that federal help is on the way.

President Biden Says “Every Asset Will Be Available” To Victims Of The Ongoing Crisis

According to AP News, Biden acknowledged the situation while in Utah, and he declared, “Anyone who’s lost a loved one, or whose home has been damaged or destroyed, is going to get help immediately.”

He also relayed that, in addition to heartfelt prayer, he’s ready to provide Hawaii with “every asset” during its time of need.

“Our prayers are with the people of Hawaii. But not just our prayers. Every asset we have will be available to them.”

Adam Weintraub, a spokesperson for Hawaii Emergency Management, told AP News that the fires are far from fully-contained, though. In fact, he declared, “We are still in life preservation mode.”

“Search and rescue is still a primary concern. Our search and rescue teams from Maui and supporting agencies are not able to do their job until the fire lines are secure and they’re sure that they’re going to be able to get to those areas safely.”

Weintraub went on to acknowledge that, while people are already antsy to play the blame game, the current priority is helping out those who are still in danger.

“I think that there is a great temptation to shift immediately to what went wrong, who’s to blame. What we have here is a natural disaster. There may have been questions that need to be examined about whether it was handled in the right way. But we still got people in danger. We still have people who don’t have homes. We still have people who can’t find their loved ones.”

Check out footage of how the Maui wildfires impacted Lahaina, the one-time capital of the Kingdom of Hawai’i, and forced people to seek refuge in the Pacific Ocean.

The scene in Lahaina, Maui this morning is absolutely devastating.

The entire town is being destroyed by an intense wildfire, forcing residents to sheek shelter in the ocean.

Biden’s Pledge Comes As The Maui Death Toll Rises To At Least 36 People

NBC News reports that there are currently six fires raging through Maui, and Hawaii Emergency Management is cited as noting that around 2,000 acres have burned. Winds from Hurricane Dora helped fuel the conflagration, which began on Tuesday evening (Aug. 8).

The outlet also notes that, as of Thursday (Aug. 10), at least 36 people have lost their lives. However, officials reportedly warn that the number could rise even higher.

In light of the ongoing situation, Hawaii Gov. Josh Green (D) ordered that the state capitol fly the flags at half-mast.

New ‘Nature’ Examine Finds Very Little Hazard Of Methane Reaching Floor • Watts Up With That?

From the NoTricksZone

By P Gosselin

A Nature study finds there’s very little risk that global warming would lead to more methane escaping from the oceans into the atmosphere.

Hat-tip: EIKE here.

Global warming alarmists have often used the scenario of increased methane in the atmosphere accelerating warming and climatic change.

But a recent study appearing in Nature, Negligible atmospheric release of methane from decomposing hydrates in mid-latitude oceans, dumps a lot cold water on this scenario. This is good news, which unfortunately the media refused to report.

At the bottom of the sea, there are large deposits of naturally occurring methane hydrate. There’s a fear that these ice-like deposits could melt and be released into the atmosphere if the oceans warmed. Methane is a far more powerful greenhouse gas than CO2. The researchers looked at the concentration and natural radiocarbon content of methane dissolved in the water column from the seafloor to the sea surface at seep fields along the US Atlantic and Pacific margins.

No methane reached the surface

Their measurements revealed no evidence of seep CH4 reaching surface waters when the water-column depth is greater than 430 ± 90 m. “Gas hydrates exist only at water depths greater than ~550 m in this region, suggesting that the source of methane escaping to the atmosphere is not from hydrate decomposition,” the authors add.

Dissolves in the ocean

In 2016, a paper published in the Reviews of Geophysics concluded that the annual emissions of methane to the ocean from degrading gas hydrates are far smaller than greenhouse gas emissions to the atmosphere from human activities and that most of the methane released by gas hydrates never even reaches the atmosphere. The methane often remains in the undersea sediments, dissolves in the ocean, or is converted to carbon dioxide by microbes.

Oceans retain virtually all the methane

The authors explain how methane sinks are increasingly incorporated into numerical models of climate-hydrate-interactions as knowledge becomes better established.

“Models are beginning to acknowledge that most CH4 bubbles emitted at the seafloor at water depths deeper than a few tens of meters will retain little or no methane by the time they reach the near-surface mixed layer, meaning that the primary repository of methane liberated by gas hydrate dissociation within any deepwater marine reservoir will be the ocean, not the atmosphere [e.g.,Biastoch et al., 2011],” the authors summarized.
