Why does the same virus barely faze one person while sending another to the hospital? New research shows the answer lies in a molecular record etched into our immune cells by both our genes and our life experiences. Scientists at the Salk Institute have created…

A groundbreaking cattle genome has given researchers their clearest look yet at what makes Wagyu beef so special. By uncovering hundreds of new genes and hidden genetic variations, scientists can now pinpoint traits linked to marbling, health, and productivity…

A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this process possible. Among the discoveries is PEDS1, a gene now linked to a previously unknown neurodevelopmental disorder in children. When…

Numerous potential treatments for neurological conditions, including autism spectrum disorders, have worked well in lab mice but then disappointed in humans. What would help is a noninvasive, objective ...

Three major reviews commissioned by the World Health Organization find that GLP-1 drugs including tirzepatide (sold as Mounjaro and Zepbound), semaglutide (Ozempic and Wegovy), and liraglutide (Victoza and Saxenda) can lead to substantial weight loss in people…

Life may have started in sticky, rock-hugging gels rather than inside cells. Researchers suggest these primitive, biofilm-like materials could trap and concentrate molecules, giving early chemistry a protected space to grow more complex. Within these gels…

The French government issued a long-awaited report Wednesday urging people to limit meat consumption for their health and also to fight climate change—and not everyone in the country of "steak-frites" ...

Women with enlarged breast tissue who experience frequent headaches are often told they have "tension headaches," but new research from Wake Forest University School of Medicine suggests many have migraine, ...

Visual experience triggers the formation of a web of neural connections in different brain areas in order to make sense of the world—and in particular, of feedback connections, which send information ...

Every year, around 15 million babies worldwide are born before 37 weeks of gestation. Being born preterm can disrupt development, and earlier births increase the risk of life-changing health outcomes. ...

You may have noticed an unexpected wellness trend gaining traction online. People are claiming a daily cup of hot water (with nothing else in it) can deliver everything from weight loss and clearer skin ...

Avian malaria is spreading across Hawaiʻi in a way scientists didn’t fully grasp until now: nearly every forest bird species can help keep the disease alive. Researchers found the parasite at 63 of 64 sites statewide, revealing that both native honeycreepers…

SARS-CoV-2–Associated Encephalopathy in Children

Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely to develop Alzheimer’s disease. Using a noninvasive brain scanning technique and a custom analysis tool, they detected subtle changes…

Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters. Climate-driven changes may reduce iron delivery to the oceans…

Nearly three years of continuous violence, severe access constraints, and reduced funding have turned Sudan into the worst humanitarian crisis globally. Over 20 million people requires health assistance and 21 million desperately needs food.

A small group of people experience no pleasure from music despite normal hearing and intact emotions. Brain imaging reveals that their auditory and reward systems fail to properly communicate, leaving music emotionally flat. Researchers developed a questionnaire…

James Cavanagh has been at the University of New Mexico for 13 years studying cognitive neuroscience and using imaging tools to understand psychiatric and neurological disorders. His most recent publication ...

Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential ...

WHO Member States today ended their latest round of intensive negotiations on the world’s first Pathogen Access andBenefit Sharing (PABS) system. Countries decided to resume deliberations in January in a reflection of the shared commitment and urgency needed…

Whole brain radiotherapy (WBRT) saves lives by treating cancer that has spread to the brain, but it also causes long-standing brain damage. Many patients who go through radiation treatment later develop ...
