Medical Xpress / Night owls experience more mental health issues than early birds and take longer to recover from work
Balancing work and personal life is more challenging for evening types, or "night owls," than for morning types, or "early birds." Evening types have a harder time recovering from work and are more likely to have mental health ...
Medical Xpress / Scientists uncover microbiome signaling system that could open new paths for IBS-related constipation
Mayo Clinic researchers have discovered that chemical signals produced by gut bacteria work together to control intestinal movement. One bacterial signal helps set the intestines in motion, while another primes gut cells ...
Medical Xpress / Breast density laws linked to higher ultrasound use after mammography
More than 40% of American women ages 40 and older have dense breast tissue, according to the National Cancer Institute. This type of tissue can make cancer harder to spot on mammograms and is itself associated with a higher ...
Medical Xpress / Tumor 'floor plans' may predict immunotherapy response better than current biomarkers
Spatial transcriptomics is a powerful tool for creating a detailed map of not just how genes are expressed in a piece of tissue, but also where genetic activity takes place in different cells and locations within the tissue. ...
Medical Xpress / Evidence often falls short in neuroscience reports of sex-dependent effects, analysis finds
Studies in the behavioral and brain sciences reporting a major sex-dependent effect—that a drug, treatment or other intervention is more effective in one sex than another—are supported by appropriate evidence less than 25% ...
Medical Xpress / Each breath is linked to brain activity, offering clues to epilepsy-related breathing failures
A new study led by researchers at the University of California San Diego shows that the brain does not simply respond to breathing as a steady rhythm. Instead, the detailed shape of each individual breath is closely linked ...
Medical Xpress / A 'one-two punch' against aggressive breast cancer could offer an alternative to chemotherapy
Triple-negative breast cancer (TNBC) has a frustrating ability to adapt. Although this aggressive form of breast cancer can initially respond well to chemotherapy, cancer cells often find ways to survive, allowing the disease ...
Medical Xpress / Cancer's malignant remote control: How tumors reprogram liver fat metabolism to disarm immune cells
In their quest to understand how cancers take root, grow and spread, scientists have for the past half-century explored the genetic aberrations and microenvironmental peculiarities of tumors and their constituent cells. Such ...
Medical Xpress / Potent antiplatelet drugs increase major bleeding risk in AF patients after heart attack

When an animal encounters a potential threat in its environment, it must focus completely on the danger to protect itself. But with repeated exposure, the threat becomes familiar and less important. The animal learns to adapt ...
Medical Xpress / Targeting protein synthesis control regions may reduce seizures in genetic epilepsy
Targeting the control of protein synthesis in the KCNQ2 gene may serve as a potential disease-modifying strategy for patients with a genetic form of neonatal-onset epilepsy and impaired brain development, according to a Northwestern ...
Medical Xpress / Hidden immune cells in the lung could lead to better flu vaccines
Influenza continues to cause major illness each year in the United States, leading to more than 35,000 deaths annually. Children, older adults, pregnant individuals, people with weakened immune systems and those with chronic ...
