Research reveals how aging cells can be an underlying cause of kidney damage
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and.....»»
Defense or repair: How immune cells are controlled during wound healing
Scientists show a causal link between tissue repair, mitochondrial metabolism, and the activation and function of macrophages (scavenger cells)......»»
Coping with schizophrenia, when emotions can be too much
Psychologists have revealed a surprising finding that could help those who struggle with schizophrenia: While people with the illness tend to manage low-level negative emotions, they struggle to do so as those negative emotions increase......»»
Breast cancer classified into 12 unique biological groups
Researchers have demonstrated a major step forward in melding two key methods for studying breast cancer: one by genetic analysis and the second by looking at the architecture of cells, or their pathology. Using The Cancer Genome Atlas Breast Cancer.....»»
Detailed images of molecule associated with ALS could open door to therapies
Scientists have determined the structure of the molecule associated with amyotrophic lateral sclerosis (ALS) and multiple other neurodegenerative diseases. The researchers say this discovery could enable targeted development of new medical interventi.....»»
Tau and PQBP1: Protein interaction induces inflammation in the brain
Researchers have clarified the relationship between the intracellular receptor PQBP1 and the structural protein Tau, which is dysregulated in neurodegenerative diseases such as Alzheimer's disease. Tau was found to interact with PQBP1 in immune cells.....»»
Soft tissue destruction and lower back pain
Back pain affects many people at some point in their lives, and a common cause is damage to the squishy discs or flexible, rubbery tissues of the spine. However, observing this damage at an early stage is difficult with current imaging methods. Now,.....»»
Blood from marathoner mice boosts brain function in their couch-potato counterparts
Researchers have shown that blood from young adult mice that are getting lots of exercise benefits the brains of same-aged, sedentary mice. A single protein in the blood of exercising mice seems largely responsible for that benefit......»»
New findings about cluster headaches
Debilitating cluster headaches commonly begin in childhood, but patients are not typically diagnosed until they are adults, according to new research......»»
Imagining future guilt helps athletes turn away from doping
Appealing to athletes' sense of 'future guilt' through psychological intervention could prove a powerful weapon in the fight against doping, according to a new study......»»
Reimagining immunity in the eye
Immune cells could be doing much more than we think in protecting our eyes -- researchers uncover new details......»»
Anxiety drugs and antidepressants trigger post-surgery delirium, study finds
A new study finds that older people taking a drug used to treat anxiety and insomnia -- nitrazepam -- as well as those on antidepressants, are twice as likely to suffer postoperative delirium after hip and knee surgery......»»
Physical features boost the efficiency of quantum simulations
Recent theoretical breakthroughs have settled two long-standing questions about the viability of simulating quantum systems on future quantum computers, overcoming challenges from complexity analyses to enable more advanced algorithms......»»
Natural infection and vaccination together provide maximum protection against COVID variants
A combination of vaccination and naturally acquired infection appears to boost the production of maximally potent antibodies against the COVID-19 virus, new research finds......»»
Early warning signals could help monitor disease outbreaks
New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and.....»»
Guidelines may promote over-diagnosis of cow"s milk allergy in infants, study finds
International guidelines developed to help doctors diagnose cow's milk allergy may lead to over-diagnosis, according to new research. The study found that three-quarters of infants have two or more symptoms at some point in the first year of life whi.....»»
Impaired-driver sensor could pave the way for safer vehicles
The bipartisan infrastructure bill recently signed into law by President Joe Biden includes a requirement for automakers to install driver monitoring systems that detect intoxicated or impaired drivers. Current systems rely on cameras, which have lim.....»»
Trends in binge drinking among older men and women in the United States
Binge drinking has increased in recent years among older U.S. men but not among older women, according to a new study......»»
Wearable sensor measures airborne nicotine exposure from e-cigarettes
Some studies have shown that nicotine, an addictive substance in electronic cigarettes, increases the risk of cardiovascular and respiratory disorders. But to get a full understanding of its potential health effects, a real-time nicotine monitoring d.....»»
CRISPR/Cas9 gene editing boosts effectiveness of ultrasound cancer therapy
Sonodynamic therapy uses ultrasound in combination with drugs to release harmful reactive oxygen species (ROS) at the site of a tumor. However, the treatment isn't very effective because cancer cells can activate antioxidant defense systems to counte.....»»
