If state lawmakers have their way, you’ll have to get a license plate for your e-bike, and if you’re planning to buy one next year, it’ll be slower. Amid growing concerns about e-bike safety, particularly among children in Bay Area suburbs, two bills introduced this year aim to make it easier to ticket riders and reduce the top speed of some models. AB 1942 would require certain e-bikes to be registered with the Department of Motor Vehicles and display license plates, and AB 1557 would slow e-bikes that children are allowed to operate. Both bills are still being reviewed in committee. If either bill passes this year, it will take effect Jan. 1.

Surging concentrations of carbon in the atmosphere, caused largely by burning fossil fuels, have produced potent changes in the way plants grow — from increasing their sugar content to depleting essential nutrients like zinc. Experts fear the degradation of Earth’s food supply will cause an epidemic of hidden hunger, in which even people who consume enough calories won’t get the nutrients they need to thrive. “The diets we eat today have less nutritional density than what our grandparents ate, even if we eat exactly the same thing,” said Kristie Ebi, a professor at the University of Washington’s Center for Health and the Global Environment.

People in wealthy countries with strong health care systems will have many tools to cope with the change, experts said. But for the world’s poorest and most vulnerable, the consequences could be devastating. One study concluded that by the middle of the century the phenomenon could put more than a billion additional women and children at risk of iron-deficiency anemia — a condition that can cause pregnancy complications, developmental problems and even death. Meanwhile, some 2 billion people across the globe who already suffer from some form of nutrient shortage could see their health problems grow even worse. “The scale of the problem is huge,” Ebi said.

Plants depend on carbon dioxide to perform photosynthesis — but that doesn’t mean they grow better when there’s more carbon in the air, scientists say. A sweeping survey of changes among 32 compounds in 43 crops found that nearly every plant that humans eat is harmed by rising CO2 levels. […] For the past several years, [Sterre F. ter Haar, an environmental scientist at Leiden University in the Netherlands and lead author of the survey] and her colleagues have worked to compile a database of all existing research on nutrient changes linked to rising CO2. They tracked down hundreds of studies, ranging from tightly controlled lab experiments to sprawling global analyses of real-world crops.

Next the team used their dataset to calculate the nutritional densities of each crop under different carbon dioxide levels — and to predict how their composition could continue to shift in the future. On average, they found, nutrients have already decreased by an average 3.2 percent across all plants since the late 1980s, when the concentration of carbon dioxide in the atmosphere was about 350 parts per million. That figure may seem small, ter Haar said, but with so much of the world already living on the brink of nutrient insufficiency, a drop of just a few percentage points has the potential to push millions of additional people into a health crisis.

The move would reverse the phase-out of nuclear energy legislation approved in the early 2000s amid safety concerns prohibiting the building of new nuclear power plants and limiting the operating lifetimes of existing ones to 40 years. Only two of Belgium’s seven nuclear reactors are operational - located at plants in Doel and in Tihange - and their operating licenses were recently extended until 2035. The other five reactors were shut between 2022 and 2025 and plans to dismantle them will now be suspended.

Engie and the government said they aim to reach an agreement on the takeover of the nuclear stations by October 1st. In a joint statement with Engie, the Belgian government said the move also highlights its aim to extend operations of existing nuclear reactors and to develop “new nuclear capacity” in Belgium. “By doing so, the Belgian Government is taking responsibility for Belgium’s long-term energy future, with the objective of building a financially and economically viable activity that supports security of supply, climate objectives, industrial resilience and socio-economic prosperity,” the statement adds.

Elon Musk wrapped up his testimony on Thursday as the trial in his lawsuit against OpenAI CEO Sam Altman continued into its fourth day. OpenAI’s attorney, William Savitt, cross-examined Musk in the morning. He asked Musk about the capped nature of Microsoft’s investments in OpenAI, his involvement in negotiations about the company’s structure, and whether he knew about the OpenAI nonprofit’s recent initiatives. “I don’t know what’s going on at OpenAI,” Musk testified.

Savitt also asked Musk about his competing artificial intelligence startup, xAI. While not the main focus of the case, Musk said it is “partly” true that xAI used some of OpenAI’s models to train its own models, a process known as distilling. Musk also suggested that xAI has used OpenAI’s technology to help build the company. Musk sued OpenAI, Altman, and Greg Brockman, the company’s president, in 2024, alleging that they went back on their commitments to keep the artificial intelligence company a nonprofit and to follow its charitable mission. He claims that the roughly $38 million he donated to seed OpenAI, a company he co-founded, was used for unauthorized commercial purposes.

Once Musk wrapped up his testimony after roughly two hours of questioning on Thursday, his attorneys called Jared Birchall, who manages Musk’s billions at his family office, as their next witness. Birchall testified about his knowledge of Musk’s specific donations to OpenAI. Judge Yvonne Gonzalez Rogers oversaw the proceedings from federal court in Oakland, California. The trial will resume on Monday.

The move came amid rising concern about insider trading on prediction market platforms such as Kalshi and Polymarket, and about event contracts that can involve death or violence. On April 22, Kalshi said it had suspended and fined one U.S. Senate candidate and two candidates for the House of Representatives for political insider trading on their own campaigns.

Earlier on Thursday, a group of Democratic members of Congress called on the Commodity Futures Trading Commission to issue a rule “that prevents insider trading and corruption in the market and prohibits event contracts on the outcome of elections, war and military actions in the U.S. or abroad, sports, and government actions without a valid economic hedging interest.” Kalshi and Polymarket both praised the Senate’s action.

A newly disclosed Linux kernel vulnerability called Copy Fail (CVE-2026-31431) allows an unprivileged user to gain root access using a tiny 732-byte script, and it works with unsettling consistency across major distributions. Unlike older exploits that relied on race conditions or fragile timing, this one is a straight-line logic flaw in the kernel’s crypto subsystem. It abuses AF_ALG sockets and splice to overwrite a few bytes in the page cache of a target file, such as /usr/bin/su. Because the kernel executes from the page cache, not directly from disk, the attacker can inject code into a setuid binary in memory and immediately escalate privileges.

What makes this especially concerning is how quiet it is. The file on disk remains unchanged, so standard integrity checks see nothing wrong, while the in-memory version has already been tampered with. The same primitive can also cross container boundaries since the page cache is shared, raising the stakes for multi-tenant environments and Kubernetes nodes. The underlying issue traces back to an in-place optimization added years ago, now being rolled back as part of the fix. Until patched kernels are widely deployed, this is one of those bugs that feels less like a theoretical risk and more like a practical, reliable path to full system compromise.

The researchers ran a series of experiments on the AI model to test its clinical acumen — including actual cases like the lupus patient who’d been previously treated at the emergency department at Beth Israel in Boston. The team graded how well the AI model could provide an accurate diagnosis at three moments in time, from the triage stage in the ER, up to being admitted into the hospital. Overall, AI outperformed two experienced physicians — and did so with only the electronic health records and the limited information that had been available to the physicians at the time. “This is the big conclusion for me — it works with the messy real-world data of the emergency department, " said Dr. Adam Rodman, a clinical researcher at Beth Israel and one of the study authors. “It works for making diagnoses in the real world.”

Other parts of the study focused on case reports published in the New England Journal of Medicine and clinical vignettes to suss out whether the AI model could meet well-established “benchmarks” and game out thorny diagnostic questions. “The model outperformed our very large physician baseline,” said Raj Manrai, assistant professor of Biomedical Informatics at Harvard Medical School who was also part of the study. The authors emphasize the AI relied on text alone, while in real life, clinicians need to attend to many other inputs like images, sounds and nonverbal cues when diagnosing and treating a patient.

It formally opened (PDF) a judicial investigation on April 29, covering alleged fraudulent access to a state-run automated data processing system and the extraction of data from it. Each offense carries a potential prison sentence of seven years and a maximum ~$350,000 fine. Public Prosecutor Laure Beccuau has requested that the minor, whose pronouns, like their name, were also not specified, be formally charged and placed under judicial supervision.

[…] France’s approach to punishing minors via its legal system is typically geared toward re-education and rehabilitation rather than prison time. While those aged between 13 and 16 can face time in juvenile detention, it is often used as a last resort measure. The maximum sentences and fines for the charges the 15-year-old in this case faces are upper limits imposed on adult offenders, and would likely be lowered substantially in cases involving a minor, like this one.

Minister of Technology and Science Felix Mutati first announced the postponement on April 28, saying that Zambia needed more time to ensure the conference “fully [aligns] with national procedures, diplomatic protocols, and the broader objective of fostering a balanced and consensus-driven platform for dialogue.” “In particular, certain invited speakers and participants remain subject to pending administrative and security clearances, which have not yet been concluded,” he added, according to the Lusaka Times.

[…] On a popular listserv for academics, many of whom are attending RightsCon, a board member of Access Now wrote “I am told I can leak that RightsCon has been canceled. Message from [Access Now] following shortly” in a thread about what attendees were planning on doing. And in an email, AccessNow wrote: “It is with heavy hearts that we share: RightsCon will not proceed in Zambia or online. We understand this news is deeply upsetting for our community and while we know everyone has questions, our goal right now is to notify you of the event’s status because many of you have imminent travel plans. We do not recommend registered participants travel to Lusaka for RightsCon.

Over the last 48 hours we have experienced an overwhelming surge of support from civil society, government representatives, sponsors, and our community as a whole. For this, we wholeheartedly thank you. We’ll communicate more information soon.”

Several times in the last couple of decades, Microsoft has released source code for the original MS-DOS operating system that kicked off its decades-long dominance of consumer PCs. This week, the company has reached further back than ever, releasing “the earliest DOS source code discovered to date" along with other documentation and notes from its developer.

Today’s source release is so old that it predates the MS-DOS branding, and it includes “sources to the 86-DOS 1.00 kernel, several development snapshots of the PC-DOS 1.00 kernel, and some well-known utilities such as CHKDSK,” write Microsoft’s Stacey Haffner and Scott Hanselman in their co-authored post about the release. […] This source code is old enough that it hadn’t been stored digitally. “A dedicated team of historians and preservationists led by Yufeng Gao and Rich Cini,” calling itself the “DOS Disassembly Group,” painstakingly transcribed and scanned in code from paper printouts provided by Paterson. This process was made even more difficult because modern OCR software struggled with the quality of the decades-old printout.

Charles Lieber, 67, is among the world’s leading researchers in brain-computer interfaces. The technology has shown promise in treating conditions such as ALS and restoring movement in paralyzed patients. But it also has potential military applications: Scientists at China’s People’s Liberation Army have investigated brain interfaces as a way to engineer super soldiers by boosting mental agility and situational awareness, according to the U.S. Defense Department. Lieber was found guilty by a jury and convicted in December 2021 of making false statements to federal investigators about his ties to a Chinese state program to recruit overseas talent, and tax offenses related to payments he received from a Chinese university. He served two days in prison and six months under house arrest, and was fined $50,000 and ordered to pay $33,600 in restitution to the Internal Revenue Service. During the case, his defense said he was suffering from an incurable lymphoma, which was in remission, and he was fighting for his life.

Three years after he was sentenced, Reuters has learned that Lieber is now overseeing China’s state-funded i-BRAIN, or the Institute for Brain Research, Advanced Interfaces and Neurotechnologies, with access to dedicated nanofabrication equipment and primate research infrastructure unavailable to him at Harvard. The lab is an arm of the Shenzhen Medical Academy of Research and Translation, or SMART. “I arrived on April 28, 2025 with a dream and not much more, maybe a couple bags of clothes,” Lieber said of his move to China at a Shenzhen government conference in December. “Personally, my own goals are to make Shenzhen a world leader.”

SMART last year appointed Lieber as an investigator, according to a post on i-BRAIN’s website dated May 1, 2025. That news was covered by some media outlets. The same day, i-BRAIN said Lieber had also been appointed its founding director — an announcement that went unreported at the time. This story is the most comprehensive account of Lieber’s activities since he moved to China. Reuters is reporting for the first time that his lab has access to dedicated primate research facilities and chip-making equipment; that it sits within a sprawling ecosystem of state-backed institutions bankrolled by billions of dollars in government funding; and that it is housed within an institution that is luring top scientific talent back from the United States.

Switzerland’s population is now more than 9 million, with official data showing foreign nationals accounted for more than 27% by 2024. The survey, conducted on April 22 and 23 and published in newspaper Tages-Anzeiger, showed 52% of 16,176 respondents in favor of the proposal or leaning that way, while 46% took the opposite view. The rest gave no opinion. A previous poll from early March had shown 45% backing the initiative and 47% against it, the newspaper said, flagging the latest result as unusual in that Swiss referendum proposals generally lose support as the voting day comes closer. The poll had a margin of error of plus or minus 3 percentage points.

The system prompt for OpenAI’s Codex CLI contains a perplexing and repeated warning for the most recent GPT model to "never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures unless it is absolutely and unambiguously relevant to the user’s query.”

The explicit operational warning was made public last week as part of the latest open source code for Codex CLI that OpenAI posted on GitHub. The prohibition is repeated twice in a 3,500-plus word set of “base instructions” for the recently released GPT-5.5, alongside more anodyne reminders not to “use emojis or em dashes unless explicitly instructed” and to “never use destructive commands like ‘git reset —hard’ or ‘git checkout —' unless the user has clearly asked for that operation.”

Separate system prompt instructions for earlier models contained in the same JSON file do not contain the specific prohibition against mentioning goblins and other creatures, suggesting OpenAI is fighting a new problem that has popped up in its latest model release. Anecdotal evidence on social media shows some users complaining about GPT’s penchant for focusing on goblins in completely unrelated conversations in recent days.

The Justice Department on Tuesday sued Cloudera, accusing the enterprise data and artificial intelligence company of deliberately engineering a hiring process that excluded American workers from at least seven lucrative technology positions while the firm pursued permanent residency sponsorship for foreign workers on temporary visas. In a 14-page complaint filed with the Office of the Chief Administrative Hearing Officer, the department’s Civil Rights Division alleges that Cloudera, from March 31, 2024, through at least January 28, 2025, instructed job candidates to submit applications to a dedicated email address, amerijobpostings@cloudera.com, that rejected all external messages with an automated bounce-back error. The company did not advertise the roles on its public careers website or accept applications through its standard portal, as it did for non-sponsorship positions.

Cloudera then attested to the Department of Labor that it could not locate any qualified U.S. workers for the roles, which paid between approximately $180,000 and $294,000 annually, according to the filing. The positions included a Product Manager role in Santa Clara, California, with a listed salary range of $170,186 to $190,000. The case marks one of the most detailed enforcement actions under the Justice Department’s Protecting U.S. Workers Initiative, which was relaunched last year and has already produced 10 settlements targeting employers accused of discriminating against American workers in favor of temporary visa holders. “Employers cannot use the PERM sponsorship process as a backdoor for discriminating against U.S. workers,” Assistant Attorney General Harmeet K. Dhillon of the Civil Rights Division said in a statement. “The Division will not hesitate to sue companies who intentionally deter U.S. workers from applying to American jobs.”

The Tesla Semi has had one of the longest gestation periods in Tesla’s history. First unveiled in 2017, the truck was originally promised for production in 2019. That target slipped repeatedly — to 2020, then 2021, then 2022 — before Tesla finally delivered a handful of units to PepsiCo in late 2022. Those early trucks were essentially hand-built on a pilot line. Tesla spent the next three years refining the design, cutting roughly 1,000 lbs from the truck, and building out a dedicated factory adjacent to Gigafactory Nevada in Sparks. The company revealed the final production specs in February, confirming two trims: a Standard Range with 325 miles at full 82,000-lb gross combination weight, and a Long Range with 500 miles of range.

Tesla is quoting $290,000 for the 500-mile Long Range version and roughly $260,000 for the Standard Range — making it the lowest-priced Class 8 battery electric tractor on the market. The shift from a pilot line to a high-volume production line is significant. Tesla’s Semi factory is designed for an annual capacity of 50,000 trucks, though the company will ramp gradually. Analysts project deliveries between 5,000 and 15,000 units in 2026, but that sounds way too optimistic. […] Both trims feature an 800-kW tri-motor drivetrain producing 1,072 hp and support 1.2-MW Megacharger speeds, restoring 60% of range in roughly 30 minutes — conveniently timed around a driver’s mandatory rest break. Tesla has opened its first Megacharger station in Ontario, California, and has mapped 66 Megacharger locations across 15 states.
