Ikoma, Japan—Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain’s deteriorating capacity to generate new neurons—a process that primarily occurs in the hippocampus —as neural stem cells (NSCs) divide and mature. Recent research suggests this decline begins much earlier in life than previously thought, potentially starting in early adulthood. While it is established that overall decline in brain function is associated with dwindling NSCs, the precise underlying molecular changes and their timelines remain unclear. ...

Washington, D.C. (July 24, 2025) — New peer-reviewed research in the journal Science demonstrates the power of strict legal bans against industrial fishing in marine protected areas (MPAs). The analysis — which combines satellite imagery and artificial intelligence technology to detect previously untraceable vessels — reveals that most of the globe’s fully and highly protected MPAs successfully deter illegal fishing. The study is the first of its kind to demonstrate that the most strictly protected marine reserves are well ...

Proteins are life’s molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are built from 20 different types of amino acid molecules, so even a small protein made of 60 amino acids in length can, in theory, be constructed in a quinquavigintillion, or 10⁷⁸, different ways. That’s about as many atoms there are in the entire universe.  How did evolution choose the handful of amino acid combinations that result in proteins which fold, stay stable and get the job done? And can we learn these rules ...

Illegal fishing is a global problem that threatens the health of ocean ecosystems and the economic viability of the fishing industry. Marine protected areas (MPAs)—zones set aside to safeguard marine life—are a key tool for conservation, but monitoring them has been a long-standing challenge. Researchers led by the University of Wisconsin–Madison’s Jennifer Raynor showed that artificial intelligence methods applied to satellite data provide a powerful new way to assess industrial fishing activity in MPAs, bridging blind spots in current ...

In two separate studies leveraging satellite imagery and artificial intelligence techniques, researchers reveal patterns of industrial fishing in coastal marine protected areas (MPAs) worldwide. Collectively, the findings, which may seem contradictory, show that although industrial fishing vessels are present in many protected areas worldwide, MPAs with the highest levels of protection remain largely unfished. Both studies suggest that proper investment in protected areas will pay off and that synthetic aperture radar (SAR) satellite technology could be one of the key tools used ...

In a Policy Forum, Andrew Baker and colleagues discuss the recent regulatory action in Florida that has enabled the world’s first international coral exchange. The exchange was done to bolster genetic diversity in declining elkhorn coral populations, enhancing their resilience to climate change and other environmental pressures. Expanding such efforts to other coral species and regions will require international collaboration and a reevaluation of current conservation laws, note the authors. Coral reefs are among the most climate-sensitive marine ecosystems, with prolonged heat stress causing increasingly frequent and devastating bleaching events. For example, the historic ...

The global marine heatwaves (MHWs) of 2023 were unprecedented in their intensity, persistence, and scale, according to a new study. The findings provide insights into the region-specific drivers of these events, linking them to broader changes in the planet’s climate system. They may also portend an emerging climate tipping point. Marine heatwaves (MHWs) are intense and prolonged episodes of unusually warm ocean temperatures. These events pose severe threats to marine ecosystems, often resulting in widespread coral bleaching and mass mortality events. ...
