ABORTION PILL ACCESS ON TRIAL.
The U.S. Supreme Court will review the case regarding mifepristone, a key abortion pill, in its first major abortion-related hearing since the Roe v. Wade overturn. This follows a Fifth Circuit Court ruling favoring restrictions on the drug, impacting delivery and telemedicine prescriptions. This case is pivotal for mifepristone’s future availability, especially in states where abortion is legal, and challenges the FDA’s regulatory authority over the drug approved over two decades ago. The Supreme Court’s decision, expected by June, will influence the political discourse during the campaign season. Advocacy groups like the Center for Reproductive Rights and Alliance Defending Freedom highlight the high stakes of the ruling in a post-Roe landscape. The case, merging two lawsuits, scrutinizes the FDA’s decision-making and the drug’s safety, despite substantial evidence of its safety. The outcome could significantly alter abortion access and regulatory standards in the U.S. (New York Times)
MDMA THERAPY.
The Multidisciplinary Association for Psychedelic Studies (MAPS) has reached a pivotal moment by submitting its first new drug application to the FDA for a psychedelic-assisted therapy using MDMA for PTSD treatment. Founded in 1986 by Rick Doblin, Ph.D., MAPS began its first clinical trials in 2004, with its sister organization, MAPS PBC, focusing on FDA approval since 2014. The application is based on two phase 3 studies demonstrating that MDMA significantly reduces PTSD symptoms more effectively than a placebo. Patients receiving MDMA showed notable improvements, including a substantial percentage achieving remission. Amy Emerson, CEO of MAPS PBC, anticipates the application’s acceptance by February, leading to inspections and audits. If granted priority review, an FDA decision could come by August. Approval would initiate efforts to reclassify MDMA from a Schedule 1 drug, currently deemed to have no medical use and a high abuse risk. This process includes lobbying states for recognition, as federal reclassification won’t instantly apply everywhere. Post-approval, MAPS PBC aims to explore MDMA’s potential in treating other trauma-related disorders, particularly focusing on eating disorders, which significantly affect women. This submission marks the end of one chapter and the beginning of another crucial phase in psychedelic research and therapeutic application. (Fierce Biotech)

NEURALINK UNDER THE SCOPE.
The U.S. Securities and Exchange Commission (SEC) is being urged to probe Elon Musk’s claims about primate deaths in Neuralink experiments, marking the third such request this year. Musk, at a recent summit, asserted that the primates used were near death, a statement challenged by the Physicians Committee for Responsible Medicine as misleading, potentially constituting securities fraud. Investigations by WIRED contradict Musk’s claims, revealing that primates, including a healthy female macaque known as Animal 11, underwent rigorous health checks before brain-implant surgeries. Records suggest these animals were not terminal before the experiments, which led to complications and euthanasia. The controversy hinges on the accuracy of Musk’s statements regarding the animals’ health and the implications for Neuralink’s research ethics and investor communications. The Physicians Committee’s letter to the SEC is part of broader concerns over potential animal welfare violations and misinformation. The SEC has not confirmed an ongoing investigation into Musk’s comments. (Wired)
UK AI CHAOS.
The UK Judicial Office has released guidance for judges on using AI text tools like ChatGPT, advising against creating new analyses but permitting text summarization. This guidance, not legally enforceable but a recommendation, reflects the growing presence of AI in legal contexts. It highlights the risks of AI-generated misinformation, urging judges to be cautious of AI ‘hallucinations’ and to avoid entering sensitive information into public AI platforms. The guidelines acknowledge AI’s limitations, particularly its U.S.-centric data training, which could skew understanding of non-U.S. legal systems. Despite these challenges, AI tools are seen as useful for certain tasks, with judges still responsible for the final material. The guidance comes amidst increasing incidents where AI misuse in legal filings led to sanctions in the U.S. and reflects a broader, global challenge in regulating AI use in legal settings, with comprehensive legislation still pending.

GROUP THINK.
Japan, Britain, and Italy have formed a joint organization to develop a new advanced jet fighter, responding to growing threats from China, Russia, and North Korea. The agreement, merging Japan’s Mitsubishi F-X and Britain’s Tempest projects, aims for deployment by 2035. This collaboration signifies Japan’s intensified military development and its strategy to counter China’s assertiveness, while acknowledging Britain’s increasing Indo-Pacific involvement. The trilateral Global Combat Air Program (GCAP) seeks to ensure air superiority and effective deterrence in a challenging security context. It also addresses the high risks and costs associated with creating advanced fighter technology. The GCAP International Government Organization, involving major defense companies, will be headquartered in Britain and led by officials from the three countries on a rotational basis. The project’s progression depends on Japan easing its postwar export restrictions on lethal weapons, a decision pending until next year. This initiative marks Japan’s first participation in a multinational military equipment development program, highlighting its expanding defense collaborations globally. (Japan Today)
SOUTH KOREA LUNAR MISSION SUCCESS.
South Korea’s first lunar mission, Danuri, launched in August 2022, has yielded surprising findings about the Moon’s far side and beyond. Scientists reported at the American Geophysical Union meeting that Danuri, orbiting the Moon since December, has exceeded expectations. Its gamma-ray spectrometer not only analyzed the Moon’s mineral composition but also detected the most intense gamma-ray burst ever observed, emanating from a galaxy 1.9 billion light years away. Danuri also provided new insights into lunar craters, particularly near the poles, using NASA’s ‘ShadowCam’. This camera revealed details not seen in previous images, enhancing understanding of the Moon’s less-explored regions. Unexpectedly, measurements indicated that the Moon’s far side is more electrically conductive than the near side, suggesting higher heat or water content, a phenomenon still unexplained by scientists. Despite challenges with one of its polarized light cameras, Danuri’s overall performance has been commendable, surpassing its expected lifespan. The mission’s future, including its endurance through a 2025 solar eclipse, remains a focal point for researchers. (Nature)
ALONE IN THE BELT.
Launched in January 2006, the New Horizons spacecraft has made significant contributions to space exploration, now nearly twice as far from the Sun as Pluto. Its journey included a flyby of the moons of Jupiter, detailed study of Pluto’s methane ice, and a close encounter with Arrokoth, a distant Kuiper Belt Object (KBO), providing crucial insights into the Solar System’s formation. Despite its distance from the Sun, New Horizons continues to function, with all instruments active. Operating it requires advanced planning, and communication with Earth takes eight hours. The spacecraft relies on a plutonium-based RTG for power, with a lifespan extended through engineering ingenuity. New Horizons is exploring the Kuiper Belt, already identifying over 100 new KBOs and examining surface properties and moons of close-passed KBOs. The spacecraft’s encounter with Arrokoth revealed its formation from slower-moving components, offering clues about the early Solar System. The mission’s success in deep space studies, including dust detection and heliophysics, is notable. New Horizons also serves as a remote observatory, uniquely positioned for astrophysical research, such as measuring the cosmic optical and UV backgrounds. New Horizons’ future plans include potentially exiting the heliosphere, joining only a few probes in interstellar space. The mission has funding until at least 2028 or 2029, and its legacy continues to expand our understanding of the cosmos. (Ars Technica)
BIRD LEGS DO MORE THAN JUST WALK.
New research using thermal imaging on 14 Australian bird species reveals that birds regulate body heat through their legs, adjusting blood flow for temperature control. This study, published in Biology Letters, shows that birds shed heat through their beaks and legs, which lack feather insulation. This mechanism is particularly evident in tropical birds with large beaks and long legs. The study by evolutionary ecologist Alexandra McQueen and her team at Deakin University involved field observations, contrasting previous lab-based research. The researchers found that on hot days, birds use both beaks and legs to release heat, but in colder conditions, they restrict blood flow to their legs to retain warmth. This suggests that birds have more control over heat regulation in their legs than in their beaks, which are closer to the brain and require constant blood flow. The findings imply that as global temperatures rise, birds in varying climates might evolve larger legs to better cope with heat, without the disadvantage of losing heat in cold conditions. This potential “shapeshifting” in bird legs could be a significant evolutionary response to climate change. (Science)
