Not every snakebite injects venom. When venom enters the body, however, it can cause snake envenoming. This is a potentially fatal condition that mostly affects poor rural communities across tropical and subtropical regions where people don't have easy access to medical care.
Scientists have created a new coating for mitochondria that preserves their ability to produce energy, potentially opening the door to new treatments for diseases involving these tiny cellular powerhouses. The technology could one day help transfer healthy mitochondria into damaged cells, although its effectiveness in transplantation remains unproven.
The FDA has approved the first drug that directly targets Alexander disease, a devastating neurological disorder affecting fewer than one in a million people. Developed through decades of research, Zanvastro showed promising results in clinical trials, stabilizing motor function and even improving movement in some patients.
Europe's Sentinel-3C satellite has returned breathtaking images of Earth just two weeks after launch, revealing the snowy Alps, frozen Arctic islands, and brilliant turquoise Caribbean waters. Its first measurements also show promising results for tracking rising seas, melting ice sheets, and other changes reshaping our planet.
The humble amino acid glycine—the simplest of all amino acids—is everywhere. The human body produces it, and it helps make up our skin, bones and ligaments. It's found in meats like beef and has even been discovered in comets returned from outer space.
The first definitive evidence of when post-Roman lead production began in one of Europe's largest medieval lead-producing regions, the Derbyshire Peak District in central England, has been uncovered by archaeologists after centuries of mining had erased much of the archaeological evidence. The work has been published in Antiquity.
Magnetic fields are invisible yet essential components in technologies ranging from MRI scanners and particle accelerators to atomic clocks and future quantum computers. Each of these applications requires magnetic fields with specific shapes and properties. Today, creating such tailored magnetic fields requires researchers and engineers to design specialized, carefully optimized magnets or large systems of coils for each individual application—a complex and resource-intensive process.
Excessive smartphone use may be taking a hidden toll on the brain and body, with heavy scrolling linked to poorer memory, reduced attention, disrupted sleep, and potential balance problems. Researchers found that weak self-control and fear of missing out, rather than personality alone, are key factors behind problematic phone use.
A new antiviral defense system discovered by Columbia scientists could be adapted in the future into a gene editor that slows down aging in our cells and improves cancer therapies. At the same time, the discovery also sheds light on an ancient event in evolution that may have helped set the stage for the emergence of higher organisms.
Elections across the world faced a wide range of pressures on electoral integrity in 2025, from violence and misinformation and disinformation to electoral management malfunctions, cyberattacks and natural hazards, according to a new report.
