How do our facial expressions in response to seeing others in pain influence how we see and feel their pain? There are many situations where it may be helpful to suppress our emotional responses to the pain of others. For example, doctors are trained to regulate their emotional responses to the pain of their patients, which may help them to avoid exhausting their own cognitive and emotional resources. Understanding whether suppressing our own facial expressions in response to other's pain reduces our ability to empathize with them has important implications for a variety ...

How plants will fare as carbon dioxide levels continue to rise is a tricky problem and, researchers say, especially vexing in the tropics. Some aspects of plants' survival may get easier, some parts will get harder, and there will be species winners and losers. The resulting shifts in vegetation will help determine the future direction of climate change. To explore the question, a study led by the University of Washington looked at how tropical forests, which absorb large amounts of carbon dioxide, might adjust as CO2 continues to climb. Their results show ...

Chestnut Hill, MA (4/1/2021) - A gender gap in negotiation emerges as early as age eight, a finding that sheds new light on the wage gap women face in the workforce, according to new research from Boston College's Cooperation Lab, lead by Associate Professor of Psychology and Neuroscience Katherine McAuliffe. The study of 240 boys and girls between ages four and nine, published recently in the journal Psychological Science, found the gap appears when girls who participated in the study were asked to negotiate with a male evaluator, a finding that mirrors the dynamics of the negotiation gap that persists between ...

Statement Highlights: Two-thirds of people with heart disease are ages 60 and older. People who have had a heart attack or stroke are 20 times more likely to have additional cardiac events compared to people without heart disease. Lifestyle modifications and medication adherence are key strategies to address heart disease. Mobile health technology, which incorporates apps, devices, texting and phone calls, can inform and monitor older adults to support lifestyle modifications. DALLAS, April 1, 2021 -- Mobile health technology can be beneficial in encouraging lifestyle behavior changes and medication adherence among adults ages 60 and older with existing heart disease, yet more research is needed to determine what methods are the most effective, according to a new scientific statement ...

New research, led by scientists at the University of Nottingham, suggests that the environment in which men live may affect their reproductive health. The research, published in Scientific Reports, looked at the effects of geographical location on polluting chemicals found in dog testes, some of which are known to affect reproductive health. The unique research focused on dogs because, as a popular pet, they share the same environment as people and are effectively exposed to the same household chemicals as their owners. The team also looked for signs of abnormalities ...

It is well known that climate-induced sea level rise is a major threat. New research has found that previous ice loss events could have caused sea-level rise at rates of around 3.6 metres per century, offering vital clues as to what lies ahead should climate change continue unabated. A team of scientists, led by researchers from Durham University, used geological records of past sea levels to shed light on the ice sheets responsible for a rapid pulse of sea-level rise in Earth's recent past. Geological records tell us that, at the end of the last ice age around 14,600 years ago, sea levels rose at ten times the current rate due to Meltwater Pulse 1A (MWP-1A); a 500 year, ~18 metre sea-level rise event. Until now, the scientific community has not ...

Genome sequencing of thousands of SARS-CoV-2 samples shows that surges of COVID-19 cases are driven by the appearance of new coronavirus variants, according to new research from the School of Veterinary Medicine at the University of California, Davis published April 1 in Scientific Reports. "As variants emerge, you're going to get new outbreaks," said Bart Weimer, professor of population health and reproduction at the UC Davis School of Veterinary Medicine. The merger of classical epidemiology with genomics provides a tool public health authorities could use to predict the course of pandemics, whether of coronavirus, influenza or some new pathogen. Although it has just 15 genes, SARS-CoV-2 is constantly mutating. Most of these changes make very little ...

Hamilton, ON (April 1, 2021) - People living with the often-debilitating effects of Crohn's disease may finally gain some relief, thanks to ground-breaking research led by McMaster University. McMaster investigator Brian Coombes said his team identified a strain of adherent-invasive E-coli (AIEC) that is strongly implicated in the condition and is often found in the intestines of people with Crohn's disease. "If you examine the gut lining of patients with Crohn's disease, you will find that around 70 to 80 per cent of them test positive for AIEC bacteria, but one of the things we don't understand is why," said Coombes, professor and chair of the Department of Biochemistry and ...

Ishikawa, Japan - Any high-performance computing should be able to handle a vast amount of data in a short amount of time -- an important aspect on which entire fields (data science, Big Data) are based. Usually, the first step to managing a large amount of data is to either classify it based on well-defined attributes or--as is typical in machine learning--"cluster" them into groups such that data points in the same group are more similar to one another than to those in another group. However, for an extremely large dataset, which can have trillions of sample points, it is tedious to even group data points into a single cluster without huge memory requirements. "The problem can be formulated as follows: Suppose we have a clustering tool that ...

The kangaskhan, Australia's only species of endemic Pokemon in Pokemon Go, is commonly poached within its natural habitat by Pokemon trainers for use in fighting contests Researchers used several species distribution modeling algorithms to predict how climate change, on top of the already existing human-induced pressures, would impact the distribution of the kangaskhan in the future In addition to this, they found a way to measure how biased commonly used species distribution models are, and found that some models are so biased that their results weren't influenced by the data at all The ...

Obesity rates have increased dramatically in developed countries over the past 40 years -- and many people have assumed that food marketing is at least in part to blame. But are people with obesity really more susceptible to food marketing? And if they are, is that a permanent predisposition, or can it change over time? According to a new study by UBC Sauder School of Business Assistant Professor Dr. Yann Cornil (he/him/his) and French researchers, people with obesity do tend to be more responsive to food marketing -- but when their weight drops significantly, so does their responsiveness to marketing. For the study, which was published in the Journal of Consumer Psychology, the researchers followed three groups: patients with severe ...

Oak Brook, IL - The April edition of SLAS Discovery is a special issue on advances in protein degradation curated by guest editors M. Paola Castaldi, Ph.D., and Stewart L. Fisher, Ph.D. Targeted protein degradation has generated interest within the drug discovery arena due to the inhibition of one particular function of a protein not often delivering the successful results that comes from whole-protein depletion. The pharmacology of PROTACs present challenges, however, namely for the development of orally bioavailable drugs. In the article "Target Validation Using PROTACs: Applying the Four Pillars Framework" authors Rados?aw P. Nowak, Ph.D., and Lyn H. Jones, Ph.D., describe the application of a translational pharmacology framework (the four pillars) ...

Oak Brook, IL - The April edition of SLAS Technology features the cover article "Therapeutic Potential of Reactive Oxygen Species: State of the Art and Recent Advances" by Valeria Graceffa, Ph.D. (Institute of Technology Sligo, Sligo, Ireland). The cover article explores the therapeutic potential of reactive oxygen species (ROS) including applications ranging from wound healing and hair growth enhancement, to cancer treatment, stem cell differentiation and tissue engineering. At low concentrations, ROS can be utilized as inexpensive and convenient inducers of tissue regeneration, triggering stem cell differentiation and enhancing collagen synthesis. Recent cancer studies have represented ROS as the 'Achilles Heels' of cancers given their high basal levels, leaving ...

(APRIL 1, 2021) -The pandemic has exacerbated risk factors for gender-based violence, such as unemployment and financial strain, substance use, isolation, depression anxiety, and general stress, according to the American Psychological Association. That's inspired The University of Texas at San Antonio criminology and criminal justice professor Kellie Lynch, along with professor TK Logan from the University of Kentucky, to work with the National Coalition Against Domestic Violence on a national survey to investigate the impact of the COVID-19 pandemic on the dynamics of gender-based violence and the experiences of those serving victims of gender-based violence. "The consequences of the COVID-19 pandemic are far-reaching and we still have much to learn about ...

The public could lose trust in science if scientific and medical researchers choose to bypass the traditional high standards of peer-reviewed medical journals in the rush to get research data released, particularly during crises such as the COVID-19 pandemic. That's the warning from three leading medical communications organizations, that have published a joint statement in the peer-reviewed journal Current Medical Research and Opinion - asserting that the integrity of published scientific and medical research must be protected. Out today, the joint statement from the American Medical ...

Review of 40 published studies from 17 countries offers first global assessment of the collateral impact of the COVID-19 pandemic on pregnancy outcomes. Findings reveal overall increase in the chances of stillbirth and maternal death during the pandemic, but chances of pre-term birth decreased in high-income countries. Women requiring surgery for ectopic pregnancies increased almost six-fold during the pandemic across all studies, after accounting for the size of included studies (surgery rate for ectopic pregnancies during pandemic 27/37 vs pre-pandemic 73/272), and symptoms of maternal depression were also increased. Study reveals disproportionate impact ...

The pandemic is affecting every country, but not every country has equal access to the lifesaving COVID-19 vaccines. Recent estimates show that high-income countries -- which have just one-fifth of the global adult population -- have purchased more than half of the world's total vaccine doses, resulting in disparities for low- and middle-income countries. A new study by researchers at Virginia Commonwealth University investigates a key question: Will the U.S. population support donating part of its COVID-19 vaccine stockpile to less prosperous countries? "COVID-19 is a true global pandemic that has touched every nation ...

Houston Methodist has been a leader in successfully treating high-risk patients with monoclonal antibodies (mAB) for mild to moderate Covid-19 infection. Among the nation's largest providers of mAB therapy, Houston Methodist has infused nearly 4,000 patients since the FDA's Emergency Use Authorization (EUA) was issued. The hospital system was able to quickly ramp up its program once the EUA was granted by leveraging a number of resources through interdisciplinary collaboration. As more hospitals begin to ramp up for treating Covid-19 with mAB therapy, Houston Methodist's example serves as a valuable model for other medical systems to establish or expand mAB treatment programs and improve patient access to this critical therapy. A commentary outlining the challenges, ...

Abusive alcohol drinking considerably impacts human health. Alcoholism, better defined as Alcohol Use Disorders (AUD), includes a group of pathological entities related to alcohol-induced damage. Individuals with AUD exhibit compulsive alcohol drinking and negative emotional states when alcohol drinking ceases. In the most severe AUD forms, the individuals lose control over consumption despite a decided will to stop. Some controversial issues have arisen as to whether the definition of AUD can help to delimit and characterize clinical entities related to abusive alcohol ingestion. The World Health Organization (WHO) reports that approximately 3,3 million people (5,9% of global ...

New findings from a Michigan Medicine study reveal that antibody testing is predictive of prior COVID-19 infection, and rapid screening methods - even from finger pricks - are effective testing tools. Researchers analyzed antibody tests conducted on more than 500 subjects in patient care settings. They found that people who had COVID, including those with mild symptoms, produced antibodies. "For a long time, people were very worried that people with mild COVID did not make immune responses," says Charles Schuler, M.D., a clinical assistant professor of allergy and immunology at Michigan Medicine. "This should give people confidence that the tests that are available to them aren't just random number generators. They're actually giving them ...

New "sweat stickers" may streamline the early diagnosis of cystic fibrosis by enabling scientists to easily gather and analyze sweat from the skin of infants and children. The stickers matched the performance of previous, more cumbersome devices when tested with 51 subjects, suggesting the stickers could address design obstacles that have held back the diagnosis and treatment of cystic fibrosis in pediatric patients. Diagnosing cystic fibrosis in infancy or childhood is critical to achieve good outcomes, as current treatments must be given early to extend lifespans and alter the course of the disease. Many current diagnostics work by detecting levels of chloride in sweat, which are elevated in cystic fibrosis patients. However, these tests must often be repeated and use unwieldy wrist-wrapped ...

For many parents, the COVID-19 pandemic has made life's everyday juggling act--managing work, school, extracurricular, and household responsibilities--much, much harder. And according to a new study led by Penn sociologists, those extra burdens have fallen disproportionately on mothers. The research, shared in the April issue of the journal Gender and Society, investigated how shifts in work and school that arose due to the pandemic triggered changes in the division of labor in families. Using data on two-parent households from a nationwide survey conducted in April 2020, the researchers found that ...

Scientists from the Skoltech Center for Energy Science and Technology (CEST) have developed a method for modeling the behavior of 2D materials under pressure. The research will help create pressure sensors based on silicene or other 2D materials. The paper was published in the ACS Nano journal. Silicene, which is regarded as the silicon analog of graphene, is a two-dimensional allotrope of silicon. In its normal state, bulk silicon is a semiconductor with a diamond crystal type structure. As it thins down to one or several layers, its properties change dramatically. However, it has not yet been possible to study the change in the electronic properties of 2D materials at high pressure. Scientists from Russia, Italy, the United ...
