Newly identified antibacterial mechanism could inspire novel strategies to combat bacterial pathogens

Similar to how a spider traps its prey, the cells of the human immune system cooperate to trap and “eat” bacteria.

Study reveals how autoimmune antibodies can predict severe cases of COVID-19

The presence of special immune system defense molecules, called autoimmune antibodies, has been strongly tied to how poorly people fare when hospitalized with COVID-19, a new study shows.

Peanut consumption associated with reduced risk of ischemic stroke in Asian population

Asian men and women living in Japan who ate peanuts (on average 4-5 peanuts/day) had a lower risk of having an ischemic stroke or a cardiovascular disease event compared to those who did not eat peanuts, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.

Recent cannabis use associated with myocardial infarction in young adults

Adults younger than 45 years who reported recently using cannabis were 2 times more likely to have had a heart attack (myocardial infarction), and this link was stronger in frequent users, according to new research in CMAJ.

Polygenic risk scores are no better in predicting disease, says study

Scientists went through the records of more than 8,000 schizophrenia patients and identified a tool used for assessing an individual’s genetic risk for a disease.

High fat diets lead to over-eating and obesity in rats by disturbing the body clock

When rats are fed a high fat diet, this disturbs the body clock in their brain that normally controls satiety, leading to over-eating and obesity. That's according to new research published in The Journal of Physiology.

Researchers analyze the effects of using tetrahydrocannabinol during pregnancy

A group of scientists combined their mastery to obtain a thorough understanding of the risks linked with cannabis exposure at the time of pregnancy.

Study identifies global priority areas to aid conservation decision making at all levels

Using a novel modeling approach, new research published in Nature Ecology and Evolution reveals the location and intensity of key threats to biodiversity on land and identifies priority areas across the world to help inform conservation decision making at national and local levels.

Integrated strategies can help achieve biodiversity, climate, and water objectives

We are collectively failing to conserve the world's biodiversity and to mobilize natural solutions to help curb global warming. A new study carried out by the Nature Map Consortium, shows that managing a strategically placed 30% of land for conservation could safeguard 70% of all considered terrestrial plant and vertebrate animal species, while simultaneously conserving more than 62% of the world's above and below ground vulnerable carbon, and 68% of all clean water.

Research findings likely to enhance genome-based disease prediction

A recent study by the University of Oxford and co-workers identifies that the effects of an individual’s genes on their chance of getting sick declines with age.

Researchers create cardiomyocyte model using a genetic algorithm

Human-induced pluripotent stem cells can differentiate into cardiac myocytes and are employed in applications like formulating patient-specific disease models.

Old habit-controlling neurons may also play a key role in learning new tricks

Imagine working on your computer and typing the same long password you have used for years to access your email.

Novel method improves the resolution of hard X-ray nanotomography

It's been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can't. X-rays are good at penetrating into samples -; they allow you to see what happens inside batteries as they charge and discharge, for example -; but historically they have not been able to spatially image with the same precision electrons can.

Study devises novel process to purify exosomes from cow’s milk

Cells produce exosomes, the nano-sized biological capsules, to protect and courier delicate molecules across the body. The capsules are hard enough to resist enzymatic breakdown and acidic and temperature fluctuations in the bloodstream and gut, which makes them a major candidate for drug delivery.

Stress signal from fat cells could help protect against cardiac damage induced by obesity

A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study led by UT Southwestern researchers suggests.

Newly developed premature cells can support early heart development

A research group led by Massachusetts General Hospital has developed premature cells that promote early heart development but disappear soon after birth.

Researchers reveal how ubiquitous signaling molecule plays a critical role in male fertility

Mammalian sperm cannot fertilize an egg from the get-go. It's an ability acquired only after insemination, during passage through the female reproductive tract, and requires two consecutive, time-sensitive processes to provide sperm with the physical and biochemical traits necessary to complete their fundamental job.

New CRISPR-based technique for rapid screening of hundreds of genes in a single experiment

Zebrafish- small, fast-growing creatures who share many of the same genes as humans- are instrumental to many biologists, who find them uniquely well suited for studying a wide range of questions, from how organisms develop to how the nervous system drives behavior.

Insect olfaction could be used to help develop drug screening techniques

Scientists investigated a key element of the insect olfactory system to analyze how this insight might help humans.
