Diagnosis of Alzheimer’s and related dementias reduces social activity, study suggests
Despite the belief that early diagnosis of Alzheimer's disease and other dementias is crucial, a new study found that the diagnosis may unintentionally impact social relationships and activity......»»
Anticoagulant has beneficial side-effects for COVID-19 patients, study finds
Clotting problems and resulting complications are common in COVID-19 patients. Researchers have now shown that a member of the anticoagulant group of drugs not only has a beneficial effect on survival of COVID-19 patients, but also influences the dur.....»»
Coronavirus lurks and lingers in nursing home patients’ rooms, study finds
Even though most COVID-19 cases come from exposure to airborne coronavirus, a new study points to the importance of surfaces as a reservoir of risk in nursing homes -- especially certain objects close to the beds of patients who have COVID-19......»»
More evidence of an evolutionary ‘arms race’ between genes and selfish genetic elements
Researchers discover further evidence of an evolutionary arms race within organisms -- and the mechanisms at play in this arms race -- to combat selfish genetic elements......»»
Competing quantum interactions enable single molecules to stand up
Nanoscale machinery has many uses, including drug delivery, single-atom transistor technology, or memory storage. However, the machinery must be assembled at the nanoscale which is a considerable challenge for researchers......»»
PFAS exposure, high-fat diet drive prostate cells’ metabolism into pro-cancer state
A high-fat diet synergizes with exposure to PFAS to change the metabolism of benign and malignant prostate cells, according to a new study in mice......»»
Conflicting health information compromises attention and emotional responses
The 24-hour news cycle and social media bombardment often resulting in conflicting messages about health issues might be making it harder than ever for people to make critical decisions, according to a new study......»»
It takes more than one mutant copy of the PIK3CA gene to make breast cancer more aggressive, study finds
Breast cancers that have an overactive PI3K enzyme tend to be more aggressive and to spread and divide more like stem cells. But a new study uncovers a surprising relationship between PI3K activity and mutations in the PIK3CA gene that codes for the.....»»
Scientists discover sugar molecule on HIV-infected cell plays role in evading immune system
A new study shows how key features on the surface of HIV-infected cells help the disease evade detection by the immune system. It also shows how these features can be disabled......»»
Unstable housing, homelessness associated with COVID-19 re-infection
New study results demonstrate that unstable housing and homelessness is associated with a two-fold greater chance of being re-infected with SARS-CoV-2 compared to those who are securely housed. The research indicates that unstable housing was the onl.....»»
New study finds evidence of COVID antibodies in breast milk of vaccinated mothers
Researchers found that two groups of mothers -- those who had disease-acquired immunity and those with vaccine-immunity -- had high levels of antibodies in their breast milk, and these antibodies provided neutralization against SARS-CoV-2......»»
Gut microbiota differences seen in people with autism may be due to dietary preferences
Research suggested that autism spectrum disorder (ASD) may be at least partly caused by differences in the composition of the gut microbiota, based on the observation that certain types of microbes are more common in people with autism. But a new stu.....»»
Lingering COVID symptoms in young, competitive athletes rare, large study finds
A new study shows that persistent symptoms following COVID-19 infections in collegiate athletes appear to be rare. Also rare is chest pain upon return to exercise, but is nonetheless a concerning finding that may warrant further clinical workup......»»
New tests track sources of lead contamination in urban soils and assess its risks
Scientists have developed a suite of isotope-based tests that can be used to identify the origin of lead contamination in urban soils and assess the risk it poses to children who inhale or ingest contaminated dirt or dust. The tests can distinguish b.....»»
Research uncovers new insights on ALS and points to a potentially promising treatment strategy
Investigators have found that an abnormal form of the tau protein is present in brain tissue from deceased patients who had amyotrophic lateral sclerosis (ALS). Cells that were grown in contact with deceased ALS patients' brain tissue that contained.....»»
Biological studies often misinterpret sex-based data, analysis finds
An analysis of published studies from a range of biological specialties shows that, when data are reported by sex, critical statistical analyses are often missing and the findings are likely to be reported in misleading ways......»»
Critical role of mechanosensor in skin wound healing
PIEZO1, an ion channel mechanosensor found within cells, has been revealed to play a key role in regulating the speed of skin wound healing......»»
Going for gold to reduce antibiotic resistance
Tiny particles of gold could be the new weapon in the fight against bacterial antibiotic resistance, according to research just published. The scientists have been investigating the use of gold nanoclusters - each made up of about 25 atoms of gold.....»»
New imaging biomarkers predict antidepressant response
The outcome predictive models were developed in part using data from a large multi-center study. The findings provide strong evidence that the current trial-and-error approach used in clinical practice for the selection of the right antidepressant ca.....»»
Listening to favorite music improves brain plasticity
Researchers have demonstrated that repeated listening to personally meaningful music induces beneficial brain plasticity in patients with mild cognitive impairment or early Alzheimer's disease......»»
