Low testosterone linked to cancer risk in men

New research shows men with very low testosterone levels are at higher risk of both fatal and nonfatal cancer later in life. But while the research found men with low testosterone were 18% more likely to die of cancer years down the track, the results did not hold for prostate ca

Ménière's disease may begin early in inner ear development

By analyzing genetic data from nearly 2 million people, researchers have unlocked a new scientific understanding of Ménière's disease, a chronic and often debilitating inner ear disorder. A team from the Perelman School of Medicine at the University of Pennsylvania found evidence

Tracking the flow of cerebrospinal fluid reveals an unprecedented view of the brain's glym

Biomedical engineers at Duke University have developed a technique to noninvasively visualize the brain's waste-removal system in unprecedented detail. This new imaging approach allows researchers to examine how this system is altered by conditions including ischemic stroke, agin

Psoriasis is linked to impairment of some sleep domains

Higher psoriasis (PsO) disease activity is independently associated with impairment in specific sleep domains, but not global sleep quality, according to a study published online May 29 in the Journal of Clinical Medicine.

Exposure to bright evening light linked to higher risk of age-related eye disease

Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern of day and night. Artificial lighting has freed human soci

Robust colorectal cancer signature identified in large-scale microbiome study

Researchers have long suspected that the gut microbiome—the community of bacteria and other microorganisms living in the intestine—is closely linked to colorectal cancer. In a new study published in Cell Host & Microbe, an international group of researchers from the Mi-EOCRC cons

Uneven cerebellum aging may partly explain why some older adults stay mentally sharp

Scientists may have discovered a new role for the cerebellum, the part of the brain that sits at the base of the skull. A new paper published in the journal Nature Neuroscience reports that different parts of the cerebellum change at different rates with age, which may be linked

Hidden protein linked to severe COVID-19 and lung disease risk

A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study published in Nature Communications.

Stress-linked gut viruses may help tumors evade the immune system

Chronic psychological stress can help tumors evade immune attack through a chain of molecular events involving gut bacteria and viruses within those bacteria, according to a study led by Weill Cornell Medicine investigators. The findings unveil a new layer of cancer biology, alon

Healthy gut microbes in 6-week-old infants linked to lower risk of malaria during first ye

In a small study in the Democratic Republic of Congo, 6-week-old infants with healthy gut microbiomes were less likely to contract malaria in their first year of life. While the study is preliminary, it suggests the possibility that treatments such as probiotics could protect aga

Armed conflict is linked to increased measles cases globally

Countries experiencing armed conflict tend to report more measles cases, and the elevated risk persists even a year after the fighting, according to new research published in PLOS Medicine. The study links armed conflict to measles in two ways: directly, by disrupting immunizatio
