Vitamin B12 corrects developmental defects in Verheij syndrome worm model‎

Verheij syndrome is a rare genetic disorder caused by the impairment of splicing, a critical process in RNA processing. Using the model organism Caenorhabditis elegans, researchers at the Max Planck Institute for Biology of Aging have demonstrated that this disruption affects metabolic pathways that rely on vitamin B12.

Many Americans underestimate health risks of extreme weather, new study finds‎

A changing climate increases the health risks posed by extreme weather. However, according to the 2024 Yale Climate Opinion Maps, only 47% of U.S. survey participants believed that global warming would harm them personally.

Real-time measurements reveal antiferromagnetic skyrmions move in line with an applied current‎

Skyrmions—essentially magnetic vortices—represent a promising approach in spintronics; in the future, they could serve as components in storage media or computers, potentially complementing established CMOS technologies. Researchers at Johannes Gutenberg University Mainz (JGU) have now visualized the interaction of antiferromagnetic skyrmions for the first time and shown that antiferromagnetic skyrmions move reproducibly along straight trajectories aligned with the driving electric current.

Veterinarians provide tips in case a pet dog or cat is choking‎

A favorite toy or treat can become dangerous in an instant if it gets lodged in your pet's airway. Because choking is a terrifying emergency for pets and their owners, Dr. Christine Rutter, a clinical associate professor at the Texas A&M College of Veterinary Medicine and Biomedical Sciences, shares what every pet owner and pet sitter should know about recognizing choking and responding safely.

Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms‎

Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found a way to steer these particles into some biofilms and even deform the biofilm itself in certain cases. The study is published in Soft Matter.

Australia is home to the only mass cuttlefish gathering in the world. This year these giants didn't return‎

This year's cuttlefish season has been unlike any other. Every winter, more than 100,000 giant Australian cuttlefish can usually be found mating along the rocky coastline of Point Lowly, northeast of Whyalla, South Australia. They put on shape-shifting, colorful displays in their attempts to attract a mate.

MRI study shows dogs can distinguish between human fear and sadness‎

Scientists—and dog lovers—have long known that dogs are remarkably good at interpreting our laughs, frowns and tears. But the biology behind this ability has remained largely unexplored until now. In a study published in the journal iScience on Aug. 7, researchers peered inside the brains of dogs as they viewed images of various human expressions. The brain scans revealed that dogs process smiles in a unique brain region and, for the first time, provided evidence that dogs can distinguish between negative facial expressions, including anger, sadness and fear.

El Niño alters marine life in the Pacific‎

As of June 2026, El Niño has officially arrived. This naturally recurring phenomenon is characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific, along with changes to atmospheric and oceanic circulation patterns. Its regional effects range from desert floods to delayed monsoons to shifts in where tropical cyclones are more likely to form.
