Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate system goes awry, pushing tryptophan toward harmful byproducts linked to memory
New research shows tropical forests can recover twice as fast after deforestation when their soils contain enough nitrogen. Scientists followed forest regrowth across Central America for decades and found that nitrogen plays a decisive role in how quickly trees return. Faster
A small revolution is happening in the fishing industry. Freshly frozen fish can now be thawed in a new way, and that means you will have access to super-fresh food from the sea—even if you live thousands of miles away.
A new OLED design can stretch dramatically while staying bright, solving a problem that has long limited flexible displays. The breakthrough comes from pairing a highly efficient light-emitting material with tough, transparent MXene-based electrodes. Tests showed the display

Adapting urban spaces to tackle climate change through nature-based solutions, especially in school playgrounds and environments, benefits both children and society as a whole. This is one of the main findings of a three-year study conducted by a group of experts at European
A new study by IIASA researchers offers a pioneering way to understand how climate change affects people's lives over the long term. Using a global model and the Years of Good Life (YoGL) metric, the research shows that today's emissions shape future well-being, especially for
Maintaining cellular order is a major logistical challenge: Individual mammalian cells contain billions of protein molecules, which must be synthesized, deployed, and removed with precision. In the ubiquitin-proteasome system (UPS), proteins destined for degradation are tagged
Researchers at Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) have developed an innovative microscopy technique capable of improving the observation of living cells. The study, published in Optics Letters, paves the way for a more in-depth analysis of
Global change—a term that encompasses climate change and phenomena such as changes in land use or environmental pollution—is increasingly putting ecosystems around the world under pressure. Urban soils in particular are susceptible to stressors like heat, drought, road salt,
Protein scientists could improve reproducibility and coordination across the field by rallying around a small, shared set of "model proteins," according to a new Perspective by Connecticut College chemist Marc Zimmer.
High-tech radar technology offers an unprecedented look at escaping ice speeds on Greenland and Antarctica The post Watch This Glacier Race into the Sea appeared first on Nautilus .
Canada is failing in a decades-old pledge to monitor the health of Pacific salmon, according to new research from Simon Fraser University.
Much like humans, microbial organisms can be fickle in their productivity. One moment they're cranking out useful chemicals in vast fermentation tanks, metabolizing feed to make products from pharmaceuticals and supplements to biodegradable plastics or fuels, and the next, they
Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation and other harmful high-energy particles.
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.
Oregon State University research into marine protected areas plays a crucial role in the historic High Seas Treaty that goes into effect Jan. 17.
The last time you scrubbed a streaky window or polished a porcelain appliance, you probably used a chemical called ammonia.
Plants reflect urban climate and soil conditions with remarkable precision. Using more than 80 million observations from plant identification apps, researchers at the Max Planck Institute for Biogeochemistry have produced a detailed picture of fine-scale climate and soil
When oyster farmer Luke Saindon went looking for a place to grow shellfish in Maine, he knew that picking the wrong patch of water could sink the farm before it began. So Saindon did something oyster farmers couldn't have done a generation ago: He used NASA satellite data to
Multi-ignition wildfires are not overly common. But when individual fires do converge, the consequences can be catastrophic. The largest fire on record in California, the 2020 August Complex fire, grew from the coalescence of 10 separate ignitions.
