Ann Arbor, April 6, 2021 - New data from the Centers for Disease Control and Prevention (CDC) show that one in four adults with HIV in the United States has experienced intimate partner violence (IPV), which disproportionately affects women and LGBT populations. Further, people with HIV who experienced IPV in the past 12 months were more likely to engage in behaviors associated with elevated HIV transmission risk, were less likely to be engaged in routine HIV care and more likely to seek emergency care services and have poor HIV clinical outcomes.
Sea urchins receive a lot of attention in California. Red urchins support a thriving fishery, while their purple cousins are often blamed for mowing down kelp forests to create urchin barrens. Yet for all the notice we pay them, we know surprisingly little about the microbiomes that support these spiny species.
Philadelphia, April 6, 2021 - Since the discovery of leptin in the 1990s, researchers have wondered, how does leptin, a hormone made by body fat, suppress appetite? Despite tremendous gains in the intervening three decades, many questions still remain. Now, a new study in mice describes novel neurocircuitry between midbrain structures that control feeding behaviors that are under modulatory control by leptin.
Biophysicists from Ludwig-Maximilians-Universitaet (LMU) in Munich have shown that a phenomenon known as diffusiophoresis, which can lead to a directed particle transport, can occur in biological systems.
As part of an international collaboration, researchers from ELTE Eötvös Loránd University developed a new animal model to study a rare genetic disease that can lead to blindness at the age of 40-50. The new model could open up new perspectives in our understanding of this metabolic disease and will also help to identify new potential drug candidates, according to the recent study published in Frontiers in Cell and Developmental Biology.
The universe is expanding at an ever-increasing rate, and while no one is sure why, researchers with the Dark Energy Survey (DES) at least had a strategy for figuring it out: They would combine measurements of the distribution of matter, galaxies and galaxy clusters to better understand what's going on.
During the early phase of the pandemic, approximately 40% of the COVID-19 literature was shared as preprints - freely available manuscripts that are shared prior to peer-review.
A new large-scale study led by UC Davis Health and UC San Francisco researchers assessed the risks of leukemia in children with Down syndrome. It pointed to stronger than expected associations between Down syndrome and acute myeloid leukemia (AML), one type of blood cancer.
Tweets about Russia by Donald Trump during his presidency caused short but noticeable depreciations of the rouble. Meanwhile, the introduction of new sanctions, upon which the president did not comment, had no such effect. This was the finding of a group of researchers, which included Elena Fedorova, Professor of the Faculty of Economic Sciences of HSE University.
"On a scale of one to 10, how much pain are you in?"
In a recent study published by the Journal of Pain, co-authored by Elizabeth Losin, assistant professor of psychology and director of the Social and Cultural Neuroscience lab at the University of Miami, researchers found that a patient's pain responses may be perceived differently by others based on their gender.
Glycine regulates neuronal activity in the brain
The adage goes, "Two is better than one." Well, that might be true for endeavors involving human heads, but when it comes to ears, hybrid maize tends to have a superior advantage over the parental stocks in most cases. This phenomenon, called hybrid vigor or "heterosis," has been used by agriculturalists across ages to create higher-yielding, more resistant varieties of maize all over the world.
Pain will lessen over time
Results include longer distance and walking time
8.5 million people in U.S., 250 million worldwide, have PAD
CHICAGO --- No pain means no gain when it comes to reaping exercise benefits for people with peripheral artery disease (PAD), reports a new Northwestern Medicine study.
Chestnut Hill, Mass. (4/6/2021) -- Compact logos can encourage favorable brand evaluations by signaling product safety, according to a new study by researchers at Boston College's Carroll School of Management and Indian Institute of Management Udaipur, who reviewed the opinions of 17,000 consumers and conducted additional experiments with a variety of logos.
Fossil discoveries often help answer long-standing questions about how our modern world came to be. However, sometimes they only deepen the mystery--as a recent discovery of four new species of ancient insects in British Columbia and Washington state is proving.
