A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that th

Researchers have developed a new computational approach that enables more accurate selection of genes that characterize different cellular states from mRNA-seq data, offering a more interpretable way to analyze complex biological data. The study, published in Frontiers in Immunol

An international team of researchers developed a new way to uncover hidden differences in how viruses infect and destroy individual microbial cells—solving a biological puzzle that has persisted for more than 80 years.

For decades, researchers have been trying to understand the biological roots of autism spectrum disorder (ASD), a common neurodevelopmental condition that shapes how people communicate, learn and interact with the world. One of the major hurdles is that the brain's neural network

The association between parents' body mass index (BMI) and their children's childhood BMI may be primarily due to genetic inheritance rather than any direct biological effect of parental weight during pregnancy, according to a new study published in PLOS Medicine by Tom Bond of t

A new international clinical intervention study published in Clinical Nutrition reveals the molecular and transcriptomic mechanisms through which a dietary intervention may beneficially influence gene expression. The study, led by Prof. Iris Shai and Dr. Hila Zelicha Peer from Be

Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females. The study shows that the neurotransmitter GABA boosts the cancer-protecting activ

Post-traumatic stress disorder (PTSD) remains a common condition affecting World Trade Center (WTC) responders 25 years after the attack on the Twin Towers. While the condition is considered mainly psychological, a new study sheds light on changes in the biological processes of W

Starting one's sex life and having children at a young age can run in the family. But can pregnancy have beneficial health effects, and do the partner's genes contribute to them? "We are just beginning to understand how pregnancy affects health later in life," says Associate Prof

New research suggests that higher levels of visceral fat, the fat stored deep in the abdomen, could contribute to faster biological aging in middle-aged adults. Adjunct Associate Professors Jennie Hui and Kun Zhu, from The University of Western Australia, were co-authors of the s

Why does multiple sclerosis progress quickly in some people, while others remain stable for years? Researchers from the Netherlands Institute for Neuroscience have identified biological patterns in the brain that may help explain these differences. Their study shows that these pa

Scientists have discovered a rare genetic condition that causes people to age at a much faster rate, offering fresh insights into the aging process. The study shows for the first time how a "biological clock" present in every cell of the body could contribute to age-related disea
