DURHAM, N.C. -- Humans aren't the only mammals that form long-term bonds with a single, special mate -- some bats, wolves, beavers, foxes and other animals do, too. But new research suggests the brain circuitry that makes love last in some species may not be the same in others.
The study, appearing Feb. 12 in the journal Scientific Reports, compares monogamous and promiscuous species within a closely related group of lemurs, distant primate cousins of humans from the island Madagascar.
COVID-19 vaccine prioritization should prioritize those with advanced cardiovascular (CVD) disease over well-managed CVD disease, according to an American College of Cardiology (ACC) health policy statement published in the Journal of the American College of Cardiology (JACC). All CVD patients face a higher risk of COVID-19 complications and should receive the vaccine quickly, but recommendations in this paper serve to guide clinicians in prioritizing their most vulnerable patients within the larger CVD group, while considering disparities in COVID-19 outcomes among different racia
Research over the last 20 years has shown that atherosclerosis is a chronic inflammatory condition of the arterial blood vessel wall. Soluble mediators such as cytokines and chemokines are pivotal players in this disease, promoting vascular inflammation. However, the development of anti-inflammatory therapeutics directed against such mediators that could prevent atherosclerosis has proven difficult, despite promising clinical studies in the recent past.
Remote sensing technology has become a vital tool for scientists over the past several decades for monitoring changes in land use, ice cover, and vegetation across the globe. Satellite imagery, however, is typically available at only coarse resolutions, allowing only for the analysis of broad trends over large areas.
COLUMBUS, Ohio - On the outskirts of some small Indigenous communities in the Mexican state of Oaxaca, a few volunteer guards keep watch along roads blocked by makeshift barricades of chains, stones and wood.
The invader they are trying to stop is COVID-19.
For many of Mexico's Indigenous people, poor and ignored by state and federal governments, the fight against the COVID-19 pandemic is one that rests primarily with themselves, said Jeffrey Cohen, a professor of anthropology at The Ohio State University.
A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN's Large Hadron Collider.
The quantum algorithm they developed accounts for the complexity of parton showers, which are complicated bursts of particles produced in the collisions that involve particle production and decay processes.
When we listen to speech sounds, the information that enters our left and right ear is not exactly the same. This may be because acoustic information reaches one ear before the other, or because the sound is perceived as louder by one of the ears. Information about speech sounds also reaches different parts of our brain, and the two hemispheres are specialised in processing different types of acoustic information. But how does the brain integrate auditory information from different areas?
Most countries introduced school closures during the spring of 2020 despite substantial uncertainty regarding the effectiveness in containing SARS-CoV-2. In Sweden, upper-secondary schools moved online while lower-secondary schools remained open. A comparison of parents with children in the final year of lower-secondary and first year of upper-secondary school shows that keeping the former open had limited consequences for the overall transmission of the virus. However, the infection rate doubled among lower-secondary teachers relative to upper-secondary ones.
Scientists use many different tests to investigate what happens in the brain in people experiencing stress. It is unclear to what extent the various methods with which subjects are placed under stress are comparable to each other. In a meta-analysis, a biopsychology team from Ruhr-Universität Bochum compared 31 previous studies that had investigated stress using functional magnetic resonance imaging (fMRI). The team worked out which regions of the brain are activated as standard during stress and which stress tests trigger similar activation patterns.
The move from the ancient system of £sd coinage to 100p to £1 was controversial, considered by some to be a sign of the UK's receding importance on the world stage and even as the beginning of the tumultuous relationship with Europe that ultimately led to Brexit.
But as a result of extensive analysis of a quiet backwater of recent history, Andy argues that the move towards decimalisation had little to do with Europe and in fact was a traditional British compromise.
Biomarkers play a central role in the diagnosis of disease and assessment of its course. Among the markers now in use are genes, proteins, hormones, lipids and other classes of molecules. Biomarkers can be found in the blood, in cerebrospinal fluid, urine and various types of tissues, but most of them have one thing in common: They occur in extremely low concentrations, and are therefore technically challenging to detect and quantify.
Knowledge on how cells communicate is an important key to understanding many biological systems and diseases. A research team led by researchers at the University of Gothenburg has now used a unique combination of methods to map the mechanism behind cellular communication. Their findings can potentially improve understanding of the underlying mechanism behind type 2 diabetes.
The Internet has revolutionized our lives - whether in terms of working, finding information or entertainment, connecting with others, or shopping. The online world has made many things easier and opened up previously unimaginable opportunities. At the same time, it presents both individuals and societies with major challenges: The underlying technologies do not necessarily serve users' best interests.
An international team of scientists has determined how harmless E. coli gut bacteria in chickens can easily pick up the genes required to evolve to cause a life-threatening infection. Their study, published in Nature Communications, warns that such infections not only affect the poultry industry but could also potentially cross over to infect humans.
