BUFFALO, N.Y. -- Scientists seeking to unlock the secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing.
Senescence is a natural occurrence in the life of a cell, and researchers have sought to learn about it for a couple of reasons. First, it's connected to old age: Senescent cells are thought to contribute to heart disease, arthritis, cataracts and a bevy of other age-linked conditions. Second, a lack of senescence is a hallmark of cancer cells, which bypass this process to replicate in an uncontrolled manner.
ADELPHI, MD. - For a thousand years, people have reported feeling better by meditating but there has never been a systematic study that quantified stress and how much stress changes as a direct result of meditation until now.
U.S. Army Research Laboratory researchers spent a year collaborating with a team of scientists from the University of North Texas to develop a new data processing technique that uses heart rate variability as a sensor to monitor the state of the brain. Their findings are reported in a paper published in the June edition of Frontiers in Physiology.
There is no strong evidence that vitamin D protects against pregnancy-induced high blood pressure (hypertension) or pre-eclampsia, conclude researchers in The BMJ today.
The findings support current World Health Organization guidance that evidence recommending vitamin D supplements for women during pregnancy to reduce adverse pregnancy outcomes is insufficient. However, in many countries, including the UK and the US, pregnant women are advised to take a daily dose of vitamin D.
A team of international astrophysicists may have found a solution to a problem that has perplexed scientists for more than 50 years: why are the stars in globular clusters made of material different to other stars found in the Milky Way?
In a study published by Monthly Notices of the Royal Astronomical Society, the team led by the University of Surrey, introduce a new actor to the equation that could solve the problem - a supermassive star.
NEW YORK...June 21, 2018 - Putting yourself in someone else's shoes and relying on intuition or "gut instinct" isn't an accurate way to determine what they're thinking or feeling," say researchers from Ben-Gurion University of the Negev (BGU), the University of Chicago and Northeastern University.
A deep neural network running on an ordinary desktop computer is interpreting highly technical data related to national security as well as - and sometimes better than - today's best automated methods or even human experts.
In the July 2018 issue of SLAS Discovery, a review article summarizes new methods of fragment-based lead discovery (FBLD) to identify new compounds as potential antibiotics.
An international team of researchers has discovered evidence of 27 previously unknown viruses in bees. The finding could help scientists design strategies to prevent the spread of viral pathogens among these important pollinators.
Health impacts of neonicotinoids may go well beyond bees, according to a new University of Guelph study.
U of G researchers found residues of the insecticides in the livers of wild turkeys, providing evidence that this common agrochemical is being ingested by free-ranging animals.
The researchers from the Ontario Veterinary College are among the first to study the broader effects of neonics on wildlife.
Boston, MA - Current experimental approaches in Medicaid programs--including requirements to pay premiums, contribute to health savings accounts, or to work--may lead to unintended consequences for patient coverage and access, such as confusing beneficiaries or dissuading some people from enrolling, according to a new study from Harvard T.H. Chan School of Public Health.
The study will be published online June 20, 2018 in Health Affairs.
DES PLAINES, IL--Most emergency department patients want to be involved in some aspects of medical decision-making, but they need to be invited. These are the primary findings of a study to be published in the July 2018 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
ITHACA, N.Y. - Using shotgun DNA sequencing, Cornell University researchers have demonstrated a new method for monitoring urinary tract infections (UTIs) that surpasses traditional methods in providing valuable information about the dynamics of the infection as well as the patient's biological response.
The technique is detailed in the paper "Urinary cell-free DNA is a versatile analyte for monitoring infections of the urinary tract," published June 20 in the journal Nature Communications.
Abandoned mines can serve as roost sites for bats, but because the mines pose serious risks to humans, officials often install gates at their entrances. With more than 80,000 abandoned mines in the southwestern United States, these subterranean habitats are important to bat survival as human disturbances from recreation and other activities at natural caves are affecting their use by bats.
A heat wave sweeps through a city and people swelter, running indoors to find air conditioning. But crops out in a field aren't so lucky. For them, there is no escape.
Scientists in Australia are working to understand how heat waves impact wheat. They are mixing observational studies with techniques from computer science. This will allow them to create models to understand how wheat will respond in certain conditions.
American swamp sparrows may have sung the same songs for more than 1,000 years and passed them on through generations by learning, according to researchers at Queen Mary University of London, Imperial College London and Duke University.
The study, published in Nature Communications, demonstrates that birds are capable of matching and potentially exceeding the stability of human cultural traditions despite their much smaller brains.
