Recent reporting, background, and summaries from the science desk.
Merck is poised to unveil crucial first-in-human data for its investigational Alzheimer's drug candidates, MK-2214 and MK-1167, at the prestigious Clinical Trials on Alzheimer's Disease (CTAD) 2025 conference in San Diego. Adding to this momentum, MK-2214 has already secured FDA Fast Track Designation, accelerating its development in the urgent fight against this debilitating disease.
Researchers have unveiled a surprising new role for Hormone-Sensitive Lipase (HSL), discovering it not only breaks down fat but also maintains fat cell function from within the nucleus, challenging long-held scientific assumptions. This pivotal finding, which reveals HSL deficiency leads to fat loss rather than accumulation, offers critical insights into metabolic disorders like obesity and lipodystrophy, potentially revolutionizing their understanding and treatment.
UK doctors have announced a significant breakthrough in treating Huntington's disease with the new gene therapy AMT-130, which demonstrated an impressive 75 percent slowing of disease progression in early-stage clinical trials. This groundbreaking development offers substantial hope for patients by targeting the root cause of the devastating neurodegenerative disorder, potentially ushering in a new era of treatment.
A groundbreaking gene therapy, AMT-130, has demonstrated remarkable potential by significantly slowing the progression of Huntington's disease by 75% in a pivotal Phase I/II clinical study, offering substantial hope for patients with this devastating neurodegenerative disorder. However, despite these promising results, the U.S. FDA recently indicated that the external control data from these studies are no longer considered adequate for a Biologics License Application, introducing uncertainty into its approval timeline.
Scientists at the University of Tokyo, led by Professor Tomonori Totani, have potentially discovered the first direct observational evidence of dark matter by identifying a distinctive halo of high-energy gamma rays using NASA's Fermi Gamma-ray Space Telescope. This groundbreaking finding, which aligns with theoretical predictions for dark matter particle annihilation, could fundamentally rewrite our understanding of the universe and offers a direct glimpse into the elusive substance that has puzzled scientists for decades.
In a monumental leap for sustainable energy, France's WEST facility shattered a world record on February 12, 2025, by sustaining a nuclear fusion plasma for an unprecedented 1,337 seconds, or over 22 minutes. This remarkable achievement, reaching 50 million degrees Celsius, significantly advances the global pursuit of fusion power by demonstrating critical long-duration plasma control and material resilience necessary for future commercial reactors.
In 2025, cancer research achieved significant milestones, introducing a new era of more precise, effective, and less toxic therapies that foster widespread optimism in the fight against cancer. This remarkable progress was fueled by intensified global collaboration and breakthroughs in areas such as immunotherapy, including bispecific antibodies and advanced CAR T-cell therapies, alongside the transformative integration of artificial intelligence in diagnosis and treatment planning.
NASA's Perseverance rover has made a groundbreaking discovery, detecting the first electrical activity, or "mini-lightning," in the Martian atmosphere, primarily associated with dust devils and storms. This significant finding adds Mars to the exclusive list of planets known to exhibit atmospheric electrical activity, with profound implications for understanding its climate, chemistry, and future exploration efforts.
A NASA astronaut and two Russian cosmonauts successfully launched aboard a Soyuz MS-28 spacecraft on Thanksgiving Day, November 27, 2025, docking with the International Space Station to begin an eight-month mission of scientific investigations. This significant international collaboration, however, was partially overshadowed by structural damage sustained by the Baikonur launch pad during liftoff.
The world's largest neutrino detector, JUNO, has officially commenced operations in southern China, already yielding groundbreaking results that promise to revolutionize particle physics. In a remarkable achievement, JUNO has delivered the most precise measurements of neutrino parameters ever recorded, significantly refining our understanding of neutrino "flavors" and their fundamental properties in just 59 days.
Japanese researchers at Nagoya University have unveiled the "Kasahara Gateway," a newly discovered plant tissue—the first such identification in 160 years—that crucially regulates nutrient flow to developing seeds. This groundbreaking discovery has already demonstrated its potential to revolutionize agriculture, significantly increasing crop yields, including a 9% boost in rice seed size, and promises to enhance global food production.
NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev successfully docked with the International Space Station on Thursday, November 27, 2025, marking a significant moment for international space collaboration. Their arrival expands the orbiting laboratory's crew to ten members for the next two weeks, facilitating increased research and operational activities, with two of the trio embarking on their inaugural journey into space.
