For many years, clinicians have been hesitant to diagnose adolescents with Borderline Personality Disorder (BPD), believing it was a mental health "death sentence" for a patient because there was no clear treatment. Carla Sharp, professor of psychology and director of the Developmental Psychopathology Lab at the University of Houston, begs to differ. And her new research, published in Journal of Abnormal Child Psychology backs her up. "Like adult BPD, adolescent BPD appears to be not as intractable and treatment resistant as previously thought," reports Sharp. "That means we should not shy away from identifying BPD in adolescents and we shouldn't ...

Halogen atoms (Cl and Br) strongly influence the atmospheric chemical composition. Since 1970s, scientists discovered that these atoms were responsible for depletion of ozone in the stratosphere and ground-level ozone of the Arctic. In the past decade, there is emerging recognition that halogen atoms also play important roles in tropospheric chemistry and air quality. However, the knowledge of halogen atoms in continental regions is still incomplete. "In the troposphere, halogen atoms can kick start hydrocarbon oxidation that makes ozone, modify the oxidative capacity, perturb ...

A survey of dog owners from across the U.S. shows that when it comes to seeking veterinary care for dogs, barriers to access - including a lack of trust - have more effect on the decision-making process than differences in race, gender or socioeconomic status. The results could aid veterinarians in developing outreach strategies for underserved communities. "I was interested in how different demographic groups viewed health care and how those views might affect relationships between veterinarians and their clients," says Rachel Park, a Ph.D. student at North Carolina State University and first author of a paper describing the work. "The existing literature wasn't national in scope and hadn't accounted for multiple identities held, such as one's socioeconomic status or ...

In the past 20 years, humans have suffered several serious epidemics from emerging viruses, such as SARS, swine flu, Ebola, MERS and (most recently) SARS-CoV-2. During each epidemic, an accurate, rapid, and accessible molecular diagnostic test is highly essential for the control and prevention of viral diseases. In particular, coronavirus disease 2019 (COVID-19) is spreading rapidly in most countries, resulting in a severe global pandemic, which has a profound impact on the world economy and people's normal life. Accurate and rapid diagnosis of COVID-19 has been the most crucial measure for controlling the ...

FINDINGS A study led by researchers at the UCLA Jonsson Comprehensive Cancer Center found shortening a traditional 45-day course of radiation to a five-day course delivered in larger doses is safe and as effective as conventional radiation for men with high-risk forms of prostate cancer. The findings show the five-day regimen of stereotactic body radiotherapy, a form of external beam radiation therapy that uses a higher dose of radiation, had a four-year cure rate of 82%. Severe side effects were also rare. Around 2% experienced urinary issues and less than 1% had bowel side effects. BACKGROUND Building on previous UCLA research that provided significant evidence that a shortened regimen of radiation could be ...

(Boston)--Atrial fibrillation (AF) is associated with a higher risk of complications including ischemic stroke, cognitive decline, heart failure, myocardial infarction and death. AF frequently is undetected until complications such as stroke or heart failure occur. While the public and clinicians have an intense interest in detecting AF earlier, the most appropriate strategies to detect undiagnosed AF and medical prognosis and therapeutic implications of AF detected by screening are uncertain. A new report led by Boston University School of Medicine (BUSM) researcher Emelia J. Benjamin, MD, ScM, builds upon a recently conducted National Heart, Lung, and Blood Institute's virtual workshop that focused on identifying key research priorities related to AF screening. Global experts reviewed ...

The brains of musicians have stronger structural and functional connections compared to those of non-musicians, regardless of innate pitch ability, according to new research from JNeurosci. Years of musical training shape the brain in dramatic ways. A minority of musicians -- with Mozart and Michael Jackson in their ranks -- also possess absolute pitch, the ability to identify a tone without a reference. But, it remains unclear how this ability impacts the brain. In the biggest sample to date, Leipold et al. compared the brains of professional musicians, some with absolute pitch and some without, to non-musicians. To the team's surprise, there were no strong differences ...

An extensive review of cephalopod fauna from the Northwest African Atlantic coast was performed by researchers from the University of Vigo (Spain) and the Spanish Institute of Oceanography ( END ...

A team led by plant biologists at the Universities of Freiburg and Göttingen in Germany has shown for the first time that mosses have a mechanism to protect them against cold that was previously known only in flowering plants. Professor Ralf Reski at the Cluster of Excellence Centre for Integrative Biological Signalling Studies (CIBSS) at the University of Freiburg and Professor Ivo Feussner at the Center for Molecular Biosciences (GZMB) at the University of Göttingen have also demonstrated that this mechanism has an evolutionarily independent origin - mosses and flowering ...

Every living organism has DNA, and every living organism engages in DNA replication, the process by which DNA makes an exact copy of itself during cell division. While it's a tried-and-true process, problems can arise. Break-induced replication (BIR) is a way to solve those problems. In humans, it is employed chiefly to repair breaks in DNA that cannot be fixed otherwise. Yet BIR itself, through its repairs to DNA and how it conducts those repairs, can introduce or cause genomic rearrangements and mutations contributing to cancer development. "It's kind of a double-edged sword," says Anna Malkova, professor in the Department of Biology at the University of Iowa, who has studied ...

Quantum physics allows to make statements about the behaviour of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, but are distributed over various values with certain probabilities. Often this distribution takes the form of a simple Gaussian bell curve that is encountered also in classical systems for example the distribution of balls in the Galton box experiment. However, not all quantum systems follow this simple behavior and some might deviate from the Gaussian distribution due to interactions. Prof. Dr. Jens Eisert, who heads a joint research group on theoretical physics at the Freie Universität Berlin and the Helmholtz-Zentrum Berlin, argues that once interactions ...

COLUMBUS, Ohio - Employees feel significantly less job distress if they work at companies that are open and transparent about the firm's finances, including budgets and profits, a new study found. Researchers examining data from the U.K. found that at companies with more financial transparency, workers felt more secure in their jobs, more committed to their employers and - most significantly - said they had better relationships with their managers. The link between greater transparency and lower job distress was strong and stood up even after accounting ...

January 25, 2021 - What care do veterans need when recovering after suicide attempts? The answer may be different for women compared to men veterans, reports a qualitative study in Medical Care, part of a special issue devoted to new research on suicide risk and prevention in women. The journal is published in the Lippincott portfolio by Wolters Kluwer. "The paths to recovery after a suicide attempt may vary by gender, especially among veterans," according to the new research by Lauren M. Denneson, PhD, of the HSR&D Center to Improve Veteran Involvement in Care (CIVIC) at VA Portland (Ore.) Health Care System. "Our data suggest that women emphasize relatedness whereas men emphasize competence." ...

Our bodies send out hosts of signals - chemicals, electrical pulses, mechanical shifts - that can provide a wealth of information about our health. But electronic sensors that can detect these signals are often made of brittle, inorganic material that prevents them from stretching and bending on our skin or within our bodies. Recent technological advances have made stretchable sensors possible, but their changes in shape can affect the data produced, and many sensors cannot collect and process the body's faintest signals. A new sensor design from the Pritzker School of Molecular Engineering (PME) at the University of Chicago helps solve that problem. By incorporating a patterned material that optimizes strain distribution among transistors, researchers have created stretchable ...

In the course of deciding whether to keep reading this article, you may change your mind several times. While your final choice will be obvious to an observer - you'll continue to scroll and read, or you'll click on another article - any internal deliberations you had along the way will most likely be inscrutable to anyone but you. That clandestine hesitation is the focus of research, published Jan. 20 in Nature, by Stanford University researchers who study how cognitive deliberations are reflected in neural activity. These scientists and engineers developed a system that read and decoded the ...

URBANA, Ill. - Dairy producers know early nutrition for young calves has far-reaching impacts, both for the long-term health and productivity of the animals and for farm profitability. With the goal of increasing not just body weight but also lean tissue gain, a new University of Illinois study finds enhanced milk replacer with high crude-protein dry starter feed is the winning combination. "Calves fed more protein with the starter had less fat in their body weight gain, and more protein was devoted to the development of the gastrointestinal system, compared with the lower ...

X-rays are usually difficult to direct and guide. X-ray physicists at the University of Göttingen have developed a new method with which the X-rays can be emitted more precisely in one direction. To do this, the scientists use a structure of thin layers of materials with different densities of electrons to simultaneously deflect and focus the generated beams. The results of the study were published in the journal Science Advances. To generate X-rays in ordinary X-ray tubes, electrons that have been accelerated by a high voltage, collide with a metal anode. ...

Nature is full of colour. For flowers, displaying colour is primarily a means to attract pollinators. Insects use their colour vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes. Casper van der Kooi, a biologist at the University of Groningen, uses an interdisciplinary approach to analyse the interaction between pollinators and flowers. In January, he was the first author of two review articles on this topic. Bees and other insects visit flowers to feed on nectar and pollen. In exchange for ...

Linguists from RUDN University found out how Russian speakers differentiate between similar consonants of the Greek language and associate them with Russian sounds. The results of the study were published in the Speech Communication journal. Efficient learning of a foreign language depends on a student's mother tongue and similarities between the sounds of the two languages. If they have a lot of similar sounds, foreign speech is perceived better, and if a student's mother tongue has no or few sounds similar to those of a foreign language, the progress will be slower. For example, it could be quite difficult for a Russian speaker to learn Greek, as some Greek consonants don't have Russian analogs. Linguists from RUDN University were the first to conduct a comprehensive ...

CHAMPAIGN, Ill. -- U.S. counties with higher income inequality faced higher rates of COVID-19 infections and deaths in the first 200 days of the pandemic, according to a new study. Counties with higher proportions of Black or Hispanic residents also had higher rates, the study found, reinforcing earlier research showing the disparate effects of the virus on those communities. The findings, published last week by JAMA Network Open, were based on county-level data for all 50 states and Washington, D.C. Data sources included the Centers for Disease Control and Prevention, USAFacts and the U.S. Census Bureau. The lead author of the study, Tim Liao, head of the sociology department at the University of Illinois Urbana-Champaign, initiated the study last summer after noticing that ...

When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the Milky Way galaxy, thanks to their gravitational tug on the stars they orbit. "We were thrilled to discover that Roman will be able to offer even more information about the planets throughout our galaxy than originally planned," said Shota ...

Hitting a pothole on the road in just the wrong way might create a bulge on the tire, a weakened spot that will almost certainly lead to an eventual flat tire. But what if that tire could immediately begin reknitting its rubber, reinforcing the bulge and preventing it from bursting? That's exactly what blood vessels can do after an aneurysm forms, according to new research led by the University of Pittsburgh's Swanson School of Engineering and in partnership with the Mayo Clinic. Aneurysms are abnormal bulges in artery walls that can form in brain arteries. Ruptured brain aneurysms are fatal in almost 50% of cases. The research, recently published in Experimental Mechanics, is the first to show that there are two phases of wall restructuring after an aneurysm forms, the first ...

PHILADELPHIA (January 25, 2021) - While eating less and moving more are the basics of weight control and obesity treatment, finding ways to help people adhere to a weight-loss regimen is more complicated. Understanding what features make a diet easier or more challenging to follow can help optimize and tailor dietary approaches for obesity treatment. A new paper from the University of Pennsylvania School of Nursing (Penn Nursing) analyzed different dietary approaches and clinical trials to better understand how to optimize adherence and subsequent weight reduction. The findings have been published in the Journal of Clinical Investigation. "There is not convincing evidence that one diet is universally easier to adhere to than another for extended periods, a feature necessary for long-term ...

Research by an international team of medical experts has found cancer patients could be up to four times more likely to die following cancer surgery in low to lower-middle income countries than in high-income countries. It also revealed lower-income countries are less likely to have post-operative care infrastructure and oncology services. The global observational study, published in The Lancet, explored global variation in post-operative complications and deaths following surgery for three common cancers. It was conducted by researchers from the GlobalSurg Collaborative and NIHR Global Health Unit on Global Surgery - led by the University of Edinburgh, with analysis and support from the University of Southampton. Between April 2018 and January 2019, researchers enrolled 15,958 ...

COLUMBUS, Ohio - Older minority cancer patients with poor social determinants of health are significantly more likely to experience negative surgical outcomes compared to white patients with similar risk factors, according to a new study published by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James). A new retrospective analysis of more than 200,000 patients conducted by researchers with the OSUCCC - James suggests that minority patients living in high socially vulnerable neighborhoods had a 40% increased risk of a complication ...
