China has set up its third planned state-backed investment fund to boost its semiconductor industry, with a registered capital of 344 billion yuan ($47.5 billion), according to a filing with a government-run companies registry. Reuters: The hundreds of billions of yuan invested in the sector puts into perspective President Xi Jinping's drive to achieve self-sufficiency for China in semiconductors. That commitment has taken on renewed urgency after the U.S. imposed a series of export control measures over the last couple of years, citing fears Beijing could use advanced chips to boost its military capabilities.

In 2011 Ross Ulbricht launched an anonymous, Tor-hidden "darknet" marketplace (with transactions conducted in bitcoin). By 2015 he'd been sentenced to life in prison for crimes including money laundering, distributing narcotics, and trafficking in fraudulent identity documents — without the possibility of parole.

Today a U.S. presidential candidate promised to commute that life sentence — Donald Trump, speaking at the national convention of the Libertarian Party as it prepares to nominate its own candidate for president.

Commuting Ulbricht's life sentence is "a top demand" of a political movement that intends to run its own candidate against Trump, reports Semafor: "On day one, we will commute the sentence," Trump said, offering to free the creator of what was once the internet's most infamous drug clearinghouse. "We will bring him home." His speeches more typically include a pledge to execute drug dealers, citing China as a model.

"It's time to be winners," said Trump, asking rhetorically if third party delegates wanted to go on getting single-digit protest votes. "I'm asking for the Libertarian Party's endorsement, or at least lots of your votes...."

"I've been indicted by the government on 91 different things," Trump said. "So if I wasn't a libertarian before, I sure as hell am a libertarian now."
More coverage from NBC News: At times, Trump turned on the crowd, criticizing libertarians' turnout at previous elections. "You can keep going the way you have for the last long decades and get your 3% and meet again, get another 3%," Trump said following jeers from the crowd.
Another high-profile supporter for commuting Ulbricht's sentence is actor-turned documentary maker Alex Winter. Best known for playing slacker Bill S. Preston Esq in Bill & Ted's Excellent Adventure and its sequels, Winter also directed, wrote, and co-produced the 2015 documentary Deep Web: The Untold Story of Bitcoin and the Silk Road (narrated by Keanu Reeves).

Writing earlier this month in Rolling Stone, Winter called Silk Road "inarguably a criminal operation" but also "a vibrant and diverse community of people from around the world. They were not only there for drugs but for the freedom of an encrypted and anonymous space, to convene and discuss everything from politics to literature and art, philosophy and drugs, drug recovery, and the onerous War on Drugs..." It's my firm opinion, and the opinion of many prison-system and criminal-law experts, that [Ulbricht's] sentence is disproportionate to his charges and that he deserves clemency. This case indeed reflects just one of the millions of unjust sentences in the long and failed War on Drugs... No matter what one thinks of Ulbricht, Silk Road, or the crimes that may have been committed, 10 years in prison is more than sufficient and customary punishment for those offenses or sins. Ross Ulbricht should be free.

China's rapid solar power expansion is slowing due to grid bottlenecks, market reforms, and diminishing rooftop space, with new solar builds dropping 32% in March year-on-year. Reuters reports: The country's solar power expansion is slowing due to tighter curbs on supplying excess power from rooftop solar into the grid and changes in electricity pricing that are denting the economics of new solar projects. Forecasts show China's solar build this year will be heavily outpaced by growth in its photovoltaic (PV) module manufacturing capacity, raising the prospect the country will export more solar panels despite a trade backlash in Europe and the U.S. The main factor slowing the expansion of distributed solar - installations built near the point of use, mostly on rooftops - is that there is not enough storage or transmission capacity to soak up the excess power generated when the sun is shining. That in turn is leading regulators to take away some of the price support that led to the rapid growth of distributed solar. "In the next couple of years, this is going to be a huge problem that all provinces will face as grids are oversaturated, the infrastructure is overwhelmed," said Cosimo Ries, an analyst with Trivium China, a policy research group. [...]

Renewable generators previously enjoyed a guarantee that grid operators would buy nearly all of their power at a rate tied to the coal index. That guarantee was lifted on April 1 and took effect earlier in some places, three industry experts said. Now, renewable generation is increasingly subject to less favourable market pricing. Shenhua Energy, a state-run coal and power firm, said in its first-quarter report that prices for its solar power fell 34.2% year-on-year to 283 yuan per megawatt-hour (MWh), while its coal power prices fell just 2.4% to 406 yuan per MWh. Wang Xiuqiang, a researcher at consultancy Beijing Linghang, attributed the lower solar prices and profitability to a higher proportion of market-based pricing. At the same time, grid companies are dialling back the 5% curtailment limit, "creating the risk for project owners that their generation might not be bought", said David Fishman of Shanghai-based energy consultancy the Lantau Group.

Curtailment for Huaneng Power International, a major state-owned generator, rose to 7.7% in the first quarter from 3.1% a year earlier, Jefferies analysts said in a client note, citing Huaneng management. In a further challenge, the easiest-to-site projects have already been largely developed, said Shi Lida, research manager at Yongan Guofu Asset Management. At sites still available, rooftops may need to be reinforced, grid connections may be limited, or hours of sunlight may be short. "If your costs don't continue to fall, the investment will not be cost effective," Shi said. Further reading: Germany Has Too Many Solar Panels, and It's Pushed Energy Prices Negative

The House Foreign Affairs Committee on Wednesday voted overwhelmingly to advance a bill that would make it easier for the Biden administration to restrict the export of AI systems, citing concerns China could exploit them to bolster its military capabilities. From a report: The bill, sponsored by House Republicans Michael McCaul and John Molenaar and Democrats Raja Krishnamoorthi and Susan Wild, also would give the Commerce Department express authority to bar Americans from working with foreigners to develop AI systems that pose risks to U.S. national security. Without this legislation "our top AI companies could inadvertently fuel China's technological ascent, empowering their military and malign ambitions," McCaul, who chairs the committee, warned on Wednesday.

"As the (Chinese Communist Party) looks to expand their technological advancements to enhance their surveillance state and war machine, it is critical we protect our sensitive technology from falling into their hands," McCaul added. The Chinese Embassy in Washington did not immediately respond to a request for comment. The bill is the latest sign Washington is gearing up to beat back China's AI ambitions over fears Beijing could harness the technology to meddle in other countries' elections, create bioweapons or launch cyberattacks.

An anonymous reader quotes a report from Krebs On Security: Apple and the satellite-based broadband service Starlink each recently took steps to address new research into the potential security and privacy implications of how their services geo-locate devices. Researchers from the University of Maryland say they relied on publicly available data from Apple to track the location of billions of devices globally -- including non-Apple devices like Starlink systems -- and found they could use this data to monitor the destruction of Gaza, as well as the movements and in many cases identities of Russian and Ukrainian troops. At issue is the way that Apple collects and publicly shares information about the precise location of all Wi-Fi access points seen by its devices. Apple collects this location data to give Apple devices a crowdsourced, low-power alternative to constantly requesting global positioning system (GPS) coordinates.

Both Apple and Google operate their own Wi-Fi-based Positioning Systems (WPS) that obtain certain hardware identifiers from all wireless access points that come within range of their mobile devices. Both record the Media Access Control (MAC) address that a Wi-FI access point uses, known as a Basic Service Set Identifier or BSSID. Periodically, Apple and Google mobile devices will forward their locations -- by querying GPS and/or by using cellular towers as landmarks -- along with any nearby BSSIDs. This combination of data allows Apple and Google devices to figure out where they are within a few feet or meters, and it's what allows your mobile phone to continue displaying your planned route even when the device can't get a fix on GPS.

With Google's WPS, a wireless device submits a list of nearby Wi-Fi access point BSSIDs and their signal strengths -- via an application programming interface (API) request to Google -- whose WPS responds with the device's computed position. Google's WPS requires at least two BSSIDs to calculate a device's approximate position. Apple's WPS also accepts a list of nearby BSSIDs, but instead of computing the device's location based off the set of observed access points and their received signal strengths and then reporting that result to the user, Apple's API will return the geolocations of up to 400 hundred more BSSIDs that are nearby the one requested. It then uses approximately eight of those BSSIDs to work out the user's location based on known landmarks.

In essence, Google's WPS computes the user's location and shares it with the device. Apple's WPS gives its devices a large enough amount of data about the location of known access points in the area that the devices can do that estimation on their own. That's according to two researchers at the University of Maryland, who theorized they could use the verbosity of Apple's API to map the movement of individual devices into and out of virtually any defined area of the world. The UMD pair said they spent a month early in their research continuously querying the API, asking it for the location of more than a billion BSSIDs generated at random. They learned that while only about three million of those randomly generated BSSIDs were known to Apple's Wi-Fi geolocation API, Apple also returned an additional 488 million BSSID locations already stored in its WPS from other lookups. "Plotting the locations returned by Apple's WPS between November 2022 and November 2023, Levin and Rye saw they had a near global view of the locations tied to more than two billion Wi-Fi access points," the report adds. "The map showed geolocated access points in nearly every corner of the globe, apart from almost the entirety of China, vast stretches of desert wilderness in central Australia and Africa, and deep in the rainforests of South America."

The researchers wrote: "We observe routers move between cities and countries, potentially representing their owner's relocation or a business transaction between an old and new owner. While there is not necessarily a 1-to-1 relationship between Wi-Fi routers and users, home routers typically only have several. If these users are vulnerable populations, such as those fleeing intimate partner violence or a stalker, their router simply being online can disclose their new location."

An anonymous reader quotes a report from Bloomberg: ASML Holding NV and Taiwan Semiconductor Manufacturing Co. have ways to disable the world's most sophisticated chipmaking machines in the event that China invades Taiwan, according to people familiar with the matter. Officials from the US government have privately expressed concerns to both their Dutch and Taiwanese counterparts about what happens if Chinese aggression escalates into an attack on the island responsible for producing the vast majority of the world's advanced semiconductors, two of the people said, speaking on condition of anonymity. ASML reassured officials about its ability to remotely disable the machines when the Dutch government met with the company on the threat, two others said. The Netherlands has run simulations on a possible invasion in order to better assess the risks, they added.

The remote shut-off applies to Netherlands-based ASML's line of extreme ultraviolet machines, known within the industry as EUVs, for which TSMC is its single biggest client. EUVs harness high-frequency light waves to print the smallest microchip transistors in existence -- creating chips that have artificial-intelligence uses as well as more sensitive military applications. About the size of a city bus, an EUV requires regular servicing and updates. As part of that, the company can remotely force a shut-off which would act as a kill switch, the people said, speaking on condition of anonymity. The Veldhoven-based company is the world's only manufacturer of these machines, which sell for more than $217 million apiece.

An anonymous reader quotes a report from Reuters: Europe's landmark rules on artificial intelligence will enter into force next month after EU countries endorsed on Tuesday a political deal reached in December, setting a potential global benchmark for a technology used in business and everyday life. The European Union's AI Act is more comprehensive than the United States' light-touch voluntary compliance approach while China's approach aims to maintain social stability and state control. The vote by EU countries came two months after EU lawmakers backed the AI legislation drafted by the European Commission in 2021 after making a number of key changes. [...]

The AI Act imposes strict transparency obligations on high-risk AI systems while such requirements for general-purpose AI models will be lighter. It restricts governments' use of real-time biometric surveillance in public spaces to cases of certain crimes, prevention of terrorist attacks and searches for people suspected of the most serious crimes. The new legislation will have an impact beyond the 27-country bloc, said Patrick van Eecke at law firm Cooley. "The Act will have global reach. Companies outside the EU who use EU customer data in their AI platforms will need to comply. Other countries and regions are likely to use the AI Act as a blueprint, just as they did with the GDPR," he said, referring to EU privacy rules.

While the new legislation will apply in 2026, bans on the use of artificial intelligence in social scoring, predictive policing and untargeted scraping of facial images from the internet or CCTV footage will kick in in six months once the new regulation enters into force. Obligations for general purpose AI models will apply after 12 months and rules for AI systems embedded into regulated products in 36 months. Fines for violations range from $8.2 million or 1.5% of turnover to 35 million euros or 7% of global turnover depending on the type of violations.

An anonymous reader quotes a report from Medical Xpress: A team of medical researchers at the National Children's Medical Center, Children's Hospital, Fudan University, in China, has developed a technique to freeze and thaw brain tissue without causing damage. In their study, published in the journal Cell Reports Methods, the group tested bathing brain organoid tissue in candidate chemicals before freezing them using liquid nitrogen. [...] The work involved dipping or soaking brain organoids (brain tissue grown from stem cells) in candidate compounds and then freezing and thawing them to see how they fared. After many attempts, they found one combination of solutions that worked best -- a mix of ethylene glycol, methylcellulose DMSO and Y27632. They named the solution mix MEDY.

The research team then tested MEDY under a variety of conditions to see how well it prevented damage from freezing. The conditions involved changing variables, such as the age of the organoids prior to freezing and how long they were soaked in a MEDY solution. They then allowed the organoids to resume growing after they were thawed for up to 150 days. The researchers found little difference between organoids that had been frozen and those that had not -- even those that had been frozen for as long as 18 months. As a final test, the research team used their technique on a sample of brain tissue obtained from a live human patient and found that it worked just as well.

Apple is offering discounts of up to $318 on select iPhone models in China, hoping to "defend its position in the high-end smartphone market, where it faces increasing competition from local rivals such as Huawei," reports Reuters. From the report: The increased competitive pressure on Apple comes after Huawei last month introduced its new series of high-end smartphones, the Pura 70, following the launch of the Mate 60 last August. Apple's previous discounting effort in February appears to have helped the company mitigate a sales slowdown in China. Apple's shipments in China increased by 12% in March, according to Reuters' calculations based on data from the China Academy of Information and Communications Technology (CAICT). This marks a significant improvement from the first two months of 2024, when the company experienced a 37% slump in sales.

"China's navy has apparently tested out a hypersonic rail gun," reports Futurism, describing it as "basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds."

But "during a demonstration of its power, things didn't go quite as planned." As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful. This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have. This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt."
But what's more interesting is the project itself. "Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space.... which for the record did not make it all the way to space..." Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too.
Japan and France also have railgun projects, according to a recent article from Defense One. "Yet the nation that has demonstrated the most continuing interest is China," with records of railgun work dating back as far as 2011: The Chinese team claimed that their railgun can fire a projectile 100 to 200 kilometers at Mach 6. Perhaps most importantly, it uses up to 100,000 AI-enabled sensors to identify and fix any problems before critical failure, and can slowly improve itself over time. This, they said, had enabled them to test-fire 120 rounds in a row without failure, which, if true, suggests that they solved a longstanding problem that reportedly bedeviled U.S. researchers. However, the team still has a ways to go before mounting an operational railgun on a ship; according to one Chinese article, the projectiles fired were only 25mm caliber, well below the size of even lightweight naval artillery.

As with many other Chinese defense technology programs, much remains opaque about the program...

While railguns tend to get the headlines, this lab has made advances in a wide range of electric and electromagnetic applications for the PLA Navy's warships. For example, the lab's research on electromagnetic launch technology has also been applied to the development of electromagnetic catapults for the PLAN's growing aircraft carrier fleet...

While it remains to be seen whether the Chinese navy can develop a full-scale railgun, produce it at scale, and integrate it onto its warships, it is obvious that it has made steady advances in recent years on a technology of immense military significance that the US has abandoned.

Earlier this week the Washington Post reported that America's Defense department "is growing concerned that the United Launch Alliance, one of its key partners in launching national security satellites to space, will not be able to meet its needs to counter China and build its arsenal in orbit with a new rocket that ULA has been developing for years." In a letter sent Friday to the heads of Boeing's and Lockheed Martin's space divisions, Air Force Assistant Secretary Frank Calvelli used unusually blunt terms to say he was growing "concerned" with the development of the Vulcan rocket, which the Pentagon intends to use to launch critical national security payloads but which has been delayed for years. ULA, a joint venture of Boeing and Lockheed Martin, was formed nearly 20 years ago to provide the Defense Department with "assured access" to space. "I am growing concerned with ULA's ability to scale manufacturing of its Vulcan rocket and scale its launch cadence to meet our needs," he wrote in the letter, a copy of which was obtained by The Washington Post. "Currently there is military satellite capability sitting on the ground due to Vulcan delays...."

ULA originally won 60 percent of the Pentagon's national security payloads under the current contract, known as Phase 2. SpaceX won an award for the remaining 40 percent, but it has been flying its reusable Falcon 9 rocket at a much higher rate. ULA launched only three rockets last year, as it transitions to Vulcan; SpaceX launched nearly 100, mostly to put up its Starlink internet satellite constellation. Both are now competing for the next round of Pentagon contracts, a highly competitive procurement worth billions of dollars over several years. ULA is reportedly up for sale; Blue Origin is said to be one of the suitors...

In a statement to The Post, ULA said that its "factory and launch site expansions have been completed or are on track to support our customers' needs with nearly 30 launch vehicles in flow at the rocket factory in Decatur, Alabama." Last year, ULA CEO Tory Bruno said in an interview that the deal with Amazon would allow the company to increase its flight rate to 20 to 25 a year and that to meet that cadence it was hiring "several hundred" more employees. The more often Vulcan flies, he said, the more efficient the company would become. "Vulcan is much less expensive" than the Atlas V rocket that the ULA currently flies, Bruno said, adding that ULA intends to eventually reuse the engines. "As the flight rate goes up, there's economies of scale, so it gets cheaper over time. And of course, you're introducing reusability, so it's cheaper. It's just getting more and more competitive."
The article also notes that years ago ULA "decided to eventually retire its workhorse Atlas V rocket after concerns within the Pentagon and Congress that it relied on a Russian-made engine, the RD-180. In 2014, the company entered into a partnership with Jeff Bezos' Blue Origin to provide its BE-4 engines for use on Vulcan. However, the delivery of those engines was delayed for years — one of the reasons Vulcan's first flight didn't take place until earlier this year."

The article says Cavelli's letter cited the Pentagon's need to move quickly as adversaries build capabilities in space, noting "counterspace threats" and adding that "our adversaries would seek to deny us the advantage we get from space during a potential conflict."

"The United States continues to face an unprecedented strategic competitor in China, and our space environment continues to become more contested, congested and competitive."

America's Defense Department "is rushing to expand its capacity to wage war in space," reports the New York Times, "convinced that rapid advances by China and Russia in space-based operations pose a growing threat to U.S. troops and other military assets on the ground and U.S. satellites in orbit." [T]he Defense Department is looking to acquire a new generation of ground- and space-based tools that will allow it to defend its satellite network from attack and, if necessary, to disrupt or disable enemy spacecraft in orbit, Pentagon officials have said in a series of interviews, speeches and recent statements... [T]he move to enhance warfighting capacity in space is driven mostly by China's expanding fleet of military tools in space... [U.S. officials are] moving ahead with an effort they are calling "responsible counterspace campaigning," an intentionally ambiguous term that avoids directly confirming that the United States intends to put its own weapons in space. But it also is meant to reflect this commitment by the United States to pursue its interest in space without creating massive debris fields that would result if an explosive device or missile were used to blow up an enemy satellite. That is what happened in 2007, when China used a missile to blow up a satellite in orbit. The United States, China, India and Russia all have tested such missiles. But the United States vowed in 2022 not to do any such antisatellite tests again.

The United States has also long had ground-based systems that allow it to jam radio signals, disrupting the ability of an enemy to communicate with its satellites, and is taking steps to modernize these systems. But under its new approach, the Pentagon is moving to take on an even more ambitious task: broadly suppress enemy threats in orbit in a fashion similar to what the Navy does in the oceans and the Air Force in the skies.
The article notes a recent report drafted by a former Space Force colonel cited three ways to disable enemy satellite networks: cyberattacks, ground or space-based lasers, and high-powered microwaves. "John Shaw, a recently retired Space Force lieutenant general who helped run the Space Command, agreed that directed-energy devices based on the ground or in space would probably be a part of any future system. 'It does minimize debris; it works at the speed of light,' he said. 'Those are probably going to be the tools of choice to achieve our objective." The Pentagon is separately working to launch a new generation of military satellites that can maneuver, be refueled while in space or have robotic arms that could reach out and grab — and potentially disrupt — an enemy satellite. Another early focus is on protecting missile defense satellites. The Defense Department recently started to require that a new generation of these space-based monitoring systems have built-in tools to evade or respond to possible attack. "Resiliency feature to protect against directed energy attack mechanisms" is how one recent missile defense contract described it. Last month the Pentagon also awarded contracts to two companies — Rocket Lab and True Anomaly — to launch two spacecraft by late next year, one acting as a mock enemy and the other equipped with cameras, to pull up close and observe the threat. The intercept satellite will not have any weapons, but it has a cargo hold that could carry them.
The article notes that Space Force's chief of space operations has told Senate appropriators that about $2.4 billion of the $29.4 billion in Space Force's proposed 2025 budget was set aside for "space domain awareness." And it adds that the Pentagon "is working to coordinate its so-called counterspace efforts with major allies, including Britain, Canada and Australia, through a multinational operation called Operation Olympic Defender. France has been particularly aggressive, announcing its intent to build and launch by 2030 a satellite equipped with a high-powered laser." [W]hat is clear is that a certain threshold has now been passed: Space has effectively become part of the military fighting domain, current and former Pentagon officials said. "By no means do we want to see war extend into space," Lt. Gen. DeAnna Burt, deputy chief of space operations, said at a Mitchell Institute event this year. "But if it does, we have to be prepared to fight and win."

The head of Canada's Security Intelligence Service warned Canadians against using video app TikTok, saying data gleaned from its users "is available to the government of China," CBC News reported on Friday. From a report: "My answer as director of the Canadian Security Intelligence Service (CSIS) is that there is a very clear strategy on the part of the government of China to be able to acquire personal information from anyone around the world," CSIS Director David Vigneault told CBC in an interview set to air on Saturday.

"These assertions are unsupported by evidence, and the fact is that TikTok has never shared Canadian user data with the Chinese government, nor would we if asked," a TikTok spokesperson said in response to a request for comment. Canada in September ordered a national security review of a proposal by TikTok to expand the short-video app's business in the country. Vigneault said he will take part in that review and offer advice, CBC reported.

Volkswagen has walked away from talks with Renault to jointly develop an affordable electric version of the Twingo car, Reuters reported Friday, citing sources familiar with the situation, in a setback for the EU carmakers' efforts to fend off Chinese rivals. From the report: The collapse of negotiations could mean the German carmaker may have to go it alone in developing its own affordable electric vehicle (EV). Renault will continue designing its electric Twingo, scheduled to hit the market in 2026. Both had hoped that sharing the work would cut costs that represent a key hurdle for European carmakers in the face of cheaper cars from China.

Volkswagen broke off discussions mainly because Renault had wanted to build the car in one of its plants at a time when VW is seeking to fully utilise its European production network, one of the sources said.

Microsoft is asking hundreds of employees in its China-based cloud-computing and AI operations to consider transferring outside the country, as tensions between Washington and Beijing mount around the critical technology. WSJ: Such staff, mostly engineers with Chinese nationality, were recently offered the opportunity to transfer to countries including the U.S., Ireland, Australia and New Zealand, people familiar with the matter said. The company is asking about 700 to 800 people [non-paywalled link], who are involved in machine learning and other work related to cloud computing, one of the people said.ÂThe move by one of America's biggest cloud-computing and AI companies comes as the Biden administration seeks to put tighter curbs around China's capability to develop state-of-the-art AI. The White House is considering new rules that would require Microsoft and other U.S. cloud-computing companies to get licenses before giving Chinese customers access to AI chips.

An anonymous reader quotes a report from New Scientist: Efforts to build a global quantum internet have received a boost from two developments in quantum information storage that could one day make it possible to communicate securely across hundreds or thousands of kilometers. The internet as it exists today involves sending strings of digital bits, or 0s and 1s, in the form of electrical or optical signals, to transmit information. A quantum internet, which could be used to send unhackable communications or link up quantum computers, would use quantum bits instead. These rely on a quantum property called entanglement, a phenomenon in which particles can be linked and measuring one particle instantly influences the state of another, no matter how far apart they are. Sending these entangled quantum bits, or qubits, over very long distances, requires a quantum repeater, a piece of hardware that can store the entangled state in memory and reproduce it to transmit it further down the line. These would have to be placed at various points on a long-distance network to ensure a signal gets from A to B without being degraded.

Quantum repeaters don't yet exist, but two groups of researchers have now demonstrated long-lasting entanglement memory in quantum networks over tens of kilometers, which are the key characteristics needed for such a device. Can Knaut at Harvard University and his colleagues set up a quantum network consisting of two nodes separated by a loop of optical fibre that spans 35 kilometers across the city of Boston. Each node contains both a communication qubit, used to transmit information, and a memory qubit, which can store the quantum state for up to a second. "Our experiment really put us in a position where we're really close to working on a quantum repeater demonstration," says Knaut. To set up the link, Knaut and his team entangled their first node, which contains a type of diamond with an atom-sized hole in it, with a photon that they sent to their second node, which contains a similar diamond. When the photon arrives at the second diamond, it becomes entangled with both nodes. The diamonds are able to store this state for a second. A fully functioning quantum repeater using similar technology could be demonstrated in the next couple of years, says Knaut, which would enable quantum networks connecting cities or countries.

In separate work, Xiao-Hui Bao at the University of Science and Technology of China and his colleagues entangled three nodes together, each separated by around 10 kilometers in the city of Hefei. Bao and his team's nodes use supercooled clouds of hundreds of millions of rubidium atoms to generate entangled photons, which they then sent across the three nodes. The central of the three nodes is able to coordinate these photons to link the atom clouds, which act as a form of memory. The key advance for Bao and his team's network is to match the frequency of the photons meeting at the central node, which will be crucial for quantum repeaters connecting different nodes. While the storage time was less than Knaut's team, at 100 microseconds, it is still long enough to perform useful operations on the transmitted information.

A bipartisan group of four senators led by Majority Leader Chuck Schumer is recommending that Congress spend at least $32 billion over the next three years to develop AI and place safeguards around it, writing in a report released Wednesday that the U.S. needs to "harness the opportunities and address the risks" of the quickly developing technology. AP: The group of two Democrats and two Republicans said in an interview Tuesday that while they sometimes disagreed on the best paths forward, it was imperative to find consensus with the technology taking off and other countries like China investing heavily in its development. They settled on a raft of broad policy recommendations that were included in their 33-page report. While any legislation related to AI will be difficult to pass, especially in an election year and in a divided Congress, the senators said that regulation and incentives for innovation are urgently needed.

The United States is heading to Geneva this week to start a series of diplomatic talks with the Chinese government about artificial intelligence safety and risk standards. From a report: The U.S. and China are in tight competition to dominate the AI market, both in the private sector and within their own governments. However, the two world powers have yet to agree on what it means to safely use the technologies they're developing.

The United States and China will meet in Switzerland on Tuesday, senior administration officials told reporters during a briefing Friday. Officials from the White House and State Department will lead the U.S. delegation in the talks, while China will bring a delegation co-led by its Ministry of Foreign Affairs and National Development and Reform Commission. The talks will primarily focus on AI risk and safety "with an emphasis on advanced systems," one official said. Officials from the U.S. and China also plan to discuss the work they're doing in their own countries domestically to address AI risks.

Brian Shelton's type 1 diabetes was treated with an infusion of insulin-producing pancreas cells (grown from stem cells). In 2021, the New York Times reported: Now his body automatically controls its insulin and blood sugar levels. Shelton, now 64, may be the first person cured of the disease with a new treatment that has experts daring to hope that help may be coming for many of the 1.5 million Americans suffering from Type 1 diabetes. "It's a whole new life," Shelton said. Diabetes experts were astonished but urged caution. The study is continuing and will take five years, involving 17 people with Type 1 diabetes.
"By fall 2023, three patients, including Shelton, had achieved insulin independence by day 180 post-transplant," MedScape reported (in January of 2024): In the phase 1/2 study, 14 patients with type 1 diabetes and impaired hypoglycemia awareness or recurrent hypoglycemia received portal vein infusions of VX-880 [Vertex Pharmaceutical's pancreatic islet cell replacement therapy] along with standard immunosuppression. As of the last data cut, all 14 patients demonstrated islet cell engraftment and production of endogenous insulin. After more than 90 days of follow-up, 13 of the patients have achieved A1c levels < 7% without using exogenous insulin.
Brian Shelton and another patient died, and while Vertex says their deaths were unrelated to the treatment, they have "placed the study on a protocol-specified pause, pending review of the totality of the data by the independent data monitoring committee and global regulators." (MedScape adds that Vertex "is continuing with a phase 1/2 clinical trial of a different product, VX-264, which encapsulates the same VX-880 cells in a device designed to eliminate the need for immunosuppression.")

And meanwhile, a new study in China (again using stem cell-derived islet tissue) has provided "encouraging evidence that islet tissue replacement is an effective cure for diabetic patients," the researchers wrote in Nature. The treatment was administered to 59-year-old, type-2 diabetic.

"Marked changes in the patient's glycemic control were observed as early as week 2," the researchers write, and after week 32, the patient's Time In Tight Range (TITR) "had readily reached 99% and was maintained thereafter."

Tim Levin reports via InsideEVs: Two things of note in the electric vehicle world happened today around the same time. First, the Geely Group-owned Chinese EV brand Zeekr debuted on the New York Stock Exchange today at a valuation of around $5.2 billion. Then, around 250 miles south in Washington, D.C., news emerged that the Biden Administration is set to quadruple tariffs on Chinese-made electric cars if they hit American roads. The timing may be purely coincidental. But after this week, one thing feels clearer than ever: the automotive Cold War between China and the West is fully underway, and EVs specifically are at the center of it all.

The Wall Street Journal got the scoop that the White House plans to announce higher tariffs on Chinese clean-energy imports in the coming days. Under the reported new policies, tariffs on Chinese EVs are set to quadruple, rising from the current 25% to a whopping 100%, anonymous sources told the outlet. In theory, that would substantially increase the cost of any Chinese-made EVs on our market, including, potentially, ones sold by known Western and other Asian brands. It's no secret why the U.S. is attempting to push back on Chinese EVs, to say nothing of other clean energy imports from that country like solar panels. China has spent years aggressively building up its capacity to manufacture electric cars. It's developed a stranglehold on the supply chains for lithium-ion batteries and the critical minerals they contain. It has lavished state incentives on both EV production and purchasing. In recent years, the country has emerged as a global EV powerhouse -- and, for the first time ever, an exporter on par with leaders like Japan and Germany.

Many still believe that China's cars are cheap and technologically subpar. But the truth is China has learned to build cars very, very well, as InsideEVs' own Kevin Williams discovered during a recent trip to the Beijing auto show. China's homegrown electrified vehicles range from the inexpensive -- some, like the BYD Seagull, cost less than $10,000 in their home market -- to higher-end, luxury-focused offerings like the Yangwang U8, a kind of plug-in hybrid competitor to the Mercedes G-Class that can "float" on water. From batteries to software, most are incredibly advanced. Car companies and policymakers in the U.S. (and Europe) say these cars pose a real threat to our nascent EV market, where many options still remain unaffordable and things like batteries and software are works in progress. In response, European Union officials have also launched investigations into Chinese imports that could lead to stronger tariffs. "In effect, the tariffs may end up buying the U.S. some time, rather than being a permanent solution here," concludes Levin. "After all, as Kevin Williams pointed out after going to Beijing: all of these crackdowns aren't guaranteed to yield better cars from Ford, General Motors and the rest."

According to the WSJ, the new tariffs on Chinese goods will also apply to solar panels, batteries and critical battery minerals. They're expected to be announced as soon as next week.
