Scientists identified an autoimmune mechanism linked to a major IBD risk gene, opening the door to targeted diagnosis and personalized therapies for thousands of patients. For decades, inflammatory bowel disease (IBD) has been treated as a single disorder, even though patients often experience dramatically different symptoms, disease courses, and responses to therapy. A new study [...]

Swimming matched running for fitness gains but delivered greater heart growth and more favorable molecular changes, making it potentially more beneficial for cardiovascular health. For decades, swimming and running have been considered two of the best forms of aerobic exercise for cardiovascular health. But new research suggests they may not strengthen the heart in exactly [...]

Lower vitamin C levels were linked to reduced brain volume and weaker neural connectivity in older adults, suggesting a potential connection between nutrition and brain health. Could a common vitamin help preserve the brain as we age? A new study of more than 2,000 older adults in Japan found that people with lower levels of [...]

Harvard researchers found that adding a little randomness to robot movements can prevent gridlock and dramatically boost efficiency in crowded swarms. Imagine a swarm of robots sent into a tight space to handle an urgent job, such as cleaning up an oil spill or assembling complex equipment. At first, adding more robots speeds things up. [...]

A single transistor that behaves like a brain cell in the deep freeze could help unlock the next generation of quantum computers and space exploration systems. Researchers at the University of Hong Kong (HKU) have developed a new type of brain-inspired electronic hardware that can operate at temperatures close to absolute zero. The breakthrough could [...]

Scientists found that some inherited traits can bypass the traditional rules of genetics, revealing a surprising new layer of inheritance beyond DNA. For more than a century, Gregor Mendel’s laws of inheritance have served as the foundation of genetics. But new research suggests that inheritance can be more complicated than the DNA sequences passed from [...]

DNA carries the instructions for life, but additional molecular systems help determine how those instructions are used. New research in a sea anemone reveals an unexpected role for one of these systems. DNA is often described as the blueprint of life, but a blueprint is only useful if someone knows how to read it. Across [...]

A new long-read DNA test improves rare disease diagnosis, replaces multiple existing tests, and could become the preferred global standard for genetic diagnostics. A new DNA test is providing a far more detailed view of the genome than current standard diagnostic methods, helping doctors identify rare genetic disorders more often. The test can replace up [...]

A Yale-led study uncovered unexpected communication between retinal visual pathways that were thought to operate separately. Researchers at Yale School of Medicine (YSM) have discovered unexpected insights into how the eye handles visual information. When we view a scene, the visual system quickly separates different features, including color, contrast, and motion, and processes them independently. [...]

A new cosmic bounce model suggests that remnants from a pre-Big Bang Universe may still exist today. What if some of the Universe’s oldest objects are actually older than the Big Bang itself? A new study from the University of Portsmouth suggests that ancient black holes may have survived from a time before the Universe [...]

A quantum “mini universe” made from ultracold atoms revealed that time can emerge from entropy changes inside a system, offering experimental insight into one of physics’ deepest mysteries. A scientist at the University of Birmingham has created a “mini universe” that could help answer one of science’s most fundamental questions: What is time? In a [...]

Researchers developed a brain-controlled gaming system that learns from the brain’s natural wiring, enabling fast BCI training and potentially transforming medicine, mental health, and human-computer interaction. It may not be long before video game controllers become optional. Researchers at Yale University have developed a new brain-computer interface (BCI) that allows people to play video games [...]

A major study found that common dementia risks may have a much stronger impact on women’s brains than previously recognized. Women may not only experience some dementia risk factors more often than men, but those risk factors may also have a stronger effect on their cognitive health, according to new research from the University of [...]

The aging brain may be far more capable of growth and improvement than scientists once believed. A large three-year study from researchers at The University of Texas at Dallas’ Center for BrainHealth (CBH) is challenging a long-standing assumption about aging. The findings suggest that mental sharpness is not destined to decline over time and that [...]

Semaglutide was linked to greater weight loss and a 15% lower fracture risk in people with type 2 diabetes, raising the possibility of an unexpected bone health benefit. People with type 2 diabetes who took semaglutide experienced greater weight loss and a lower risk of bone fractures than those using several other weight-loss medications, according [...]

Remote Scottish islands turned tiny wrens into giant birds that may be evolving into new species. Tiny wrens living on remote Scottish islands are providing scientists with a rare look at how evolution can reshape animals in isolated environments. A new study led by researchers at the University of Birmingham found that several island populations [...]

Scientists found that chronic wasting disease may spread silently between species, revealing a hidden challenge in the fight against the fatal wildlife disease. Chronic wasting disease (CWD) is best known as a disease affecting deer, elk, and other cervid (hooved, plant-eating) animals. Now, researchers at the University of Calgary and their international collaborators have taken [...]

The first global map of underground fungal networks reveals a hidden 68 quadrillion-mile superhighway that helps sustain life on Earth and store carbon in the soil. Beneath forests, grasslands, wetlands, and even many agricultural fields lies a vast underground fungal network that supports plant life and plays an important role in the global carbon cycle. [...]

An experimental vaccine could help stop fentanyl and future designer-drug variants before they can trigger a deadly overdose. Fentanyl has become one of the deadliest drugs in the United States, with fentanyl and related synthetic opioid variants now claiming more lives each year than car crashes and gun violence combined. When taken in excessive amounts, [...]

People taking popular GLP-1 weight-loss drugs like Ozempic, Wegovy, Mounjaro, and Zepbound may be shedding pounds, but a new study suggests they are also moving less. People with obesity who lost weight while taking popular medications such as Ozempic, Wegovy, Zepbound, and similar drugs became significantly less physically active, according to research presented at ENDO [...]
