An overgrowth of yeast in the gut within the first few months of life may cause changes to the immune system that increase the risk of asthma later on, shows a study published today in eLife.

Asthma is a common and sometimes difficult-to-manage, life-long lung condition that affects one in 10 children in developed countries. The findings explain a possible cause of asthma and may help scientists develop new strategies to prevent or treat the condition.

FAYETTEVILLE, Ark. - The fearsome tyrannosaur dinosaurs that ruled the northern hemisphere during the Late Cretaceous period (66-100 million years ago) may not have been solitary predators as popularly envisioned, but social carnivores similar to wolves, according to a new study.

The finding, based on research at a unique fossil bone site inside Utah's Grand Staircase-Escalante National Monument containing the remains of several dinosaurs of the same species, was made by a team of scientists including Celina Suarez, University of Arkansas associate professor of geosciences.

TAMPA, Fla (April 20, 2021) — Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain – an early step in the development of Alzheimer’s disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

The composition of the street drugs heroin and cocaine has dramatically changed at alarming speeds across the globe. No longer are these street drugs cut with benign materials such as lactose but now cut with up to 17 or more pharmaceutically active and potentially toxic adulterants.

A drug user may buy cocaine today but may end up with a drug cocktail more dangerous then what was bought and assumed was cocaine. This has a profound effect on public health and safety as well as on the individual street drug users during the COVID-19 pandemic.

With alarms sounding about the declining diversity of plants and animals, a related concern with equally profound implications is posed: is the variety of microbial life, including viruses, changing too -- and if so, in which direction and how fast?

Two studies led by Baylor College of Medicine shed new light on the unanswered question of why estrogen receptor-positive (ER+) breast cancer sometimes grows back in the bone and spreads to other tissues despite effective endocrine therapies directed at ER.

April 19, 2021--(BRONX, NY)--Researchers at Albert Einstein College of Medicine have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats, and the findings were published online today in JCI Insight.

Having an epidural during childbirth is not associated with a greater risk of autism in the child, according to a study led by researchers at the Stanford University School of Medicine and the University of Manitoba.

The study, which will publish online April 19 in JAMA Pediatrics, helps resolve questions raised by an earlier, widely criticized report on the topic.

What The Study Did: The association between hearing loss and level of physical activity among U.S. adults ages 60 to 69 was analyzed in this study.

Authors: Frank R. Lin, M.D., Ph.D., of the Johns Hopkins University School of Medicine in Baltimore, is the corresponding author.

Animals are constantly moving and behaving in response to instructions from the brain. But while there are advanced techniques for measuring these instructions in terms of neural activity, there is a paucity of techniques for quantifying the behavior itself in freely moving animals. This inability to measure the key output of the brain limits our understanding of the nervous system and how it changes in disease.

New research is shining light on the importance of farmers' markets' ability to mitigate potential disruptions to distribution networks in the face of system shocks like the COVID-19 pandemic.

In a recent study, the researchers found the markets' regional characteristics play a key role in the decision to move all or parts of their operations online -- and how that decision can help or hinder its surrounding community.

A COVID-19 vaccine that could provide protection against existing and future strains of the COVID-19 coronavirus, and other coronaviruses, and cost about $1 a dose has shown promising results in early animal testing.

A new study from the UBC Sauder School of Business finds a subtle shift in organ donor messaging can lead to a big boost in registration.

Organ donation saves countless lives every year, and most people think it's the right thing to do -- but when it comes to people actually registering to donate, the numbers around the world are surprisingly low. This is particularly so in countries that rely on informed consent and require people to learn about organ donation before they opt-in to register as a donor.

A forest looks like a hotbed of randomness, with trees and plants scattered in wild and capricious diversity. But appearances can be deceiving, say a trio of complexity researchers at the Santa Fe Institute (SFI). Underneath that apparent messiness lurk extraordinary regularities, governed by the biological mechanisms that drive universal forces of growth, death, and competition.

Osaka, Japan - As humans, we each have a powerful ability to easily recognize our own face. But now, researchers from Japan have uncovered new information about how our cognitive systems enable us to distinguish our own face from those of others, even when the information is presented subliminally.
