Neuroscientists observe electrical signals in the soma and dendrites of living mice

The human brain contains billions of neurons, specialized nerve cells that communicate with each other via electrical and chemical signals. Every neuron is made up of its body (i.e., soma), where most cellular processes occur; a long projection called an axon that sends signals t

Inhibiting a stress protein prevents the consequences of childhood trauma

A new study, co-led by Mathias Schmidt from the Max Planck Institute of Psychiatry in Munich and Juan Pablo Lopez from Karolinska Institutet in Sweden, focused on the FKBP5 gene and its encoded protein, FKBP51, a well-established regulator of the body's stress hormone system that

Clinical trial offers strong evidence that nerve blocks can cut opioid use after cardiac s

A clinical trial led by St. Michael's Hospital researchers found that using nerve blocks, an anesthesia technique to numb targeted areas of the body, significantly reduced opioid use after cardiac surgery—findings the authors say could reshape how the potentially addictive drugs

Study linking microgravity and space radiation to accelerated aging could yield therapies

What happens to the human body in space may help scientists create new anti-aging therapies. UCF's Michal Masternak and his team have identified molecular changes in the liver that happen when space travelers experience radiation and microgravity. These changes—that resemble acce

Largest study yet reveals which cancers have their own microbiomes

For decades, cancer has been thought of as a purely human disease—rogue cells multiplying out of control, with no room for anything else in the picture. But a growing body of research suggests that isn't quite right. Some tumors, it turns out, come with company: communities of ba

How immune cells in our gut mesentery fight salmonella

Widely recognized as the face of food poisoning, salmonella bacteria lurk in raw meat and poultry, on pets, and in unpasteurized dairy products. If untreated, extreme cases can lead to full-body infections, like typhoid fever. UIC researcher Kiwook Kim wondered why some salmonell

Gut bacteria boost immune system, help send vitamin A to T cells

Scientists at UT Southwestern Medical Center have discovered that gut bacteria help regulate the development of the body's immune system by directing the movement of vitamin A through a previously unrecognized cellular network. The preclinical findings, published in Cell Host & M

Scientists uncover how fungi 'blind' the immune system—offering new hope against superbugs

Researchers at the University of Sheffield have discovered that a fungus deadly to people with weakened immune systems can disable a critical defense used by neutrophils, the body's front-line, infection-fighting white blood cells.

How can you be tired yet wired? Blame your stone‑age brain

The clock reads 2:13 a.m. You are exhausted. Your eyes ache, your body feels heavy, and the alarm is already beginning to loom over the night, yet your brain refuses to let go. Instead, thoughts arrive in waves. Did you send that email? What if you forgot something important? Per

Cellular 'bandages' help rebuild uterine lining after monthly shedding, study finds

For most women past puberty, the uterine lining (endometrium) sheds from the body roughly every month if there is no fertilized egg present. Then, the uterus rebuilds itself to prepare for a potential pregnancy. While this process—the menstrual cycle—is widely known, how it works

Psilocybin therapy shows potential as a treatment for anorexia nervosa in small trial

A small pilot study from the Center for Psychedelic Research at Imperial College London indicates that psilocybin—the active ingredient in psychedelic "magic mushrooms"—may have potential as a treatment for anorexia nervosa when combined with therapy. Anorexia nervosa is a seriou

What World Cup football can teach us about managing fatigue in extreme conditions

A football player standing over a penalty in a hot, high-altitude stadium is dealing with more than pressure. His body is trying to keep cool. His heart and breathing may be working harder. Less oxygen is reaching his muscles. One poor decision can end his team's World Cup.
