Neural replay during waking rest may contribute to memory consolidation of action sequences in humans, according to a study published June 8 in the journal Cell Reports. Brain imaging results revealed fast, repeated reactivation of a neural network representing a behavioral sequence that people were learning--approximately 20 times the speed of the new memory--especially while they were taking breaks from practice. "This is the first demonstration of wakeful neural replay of a newly learned skill elicited by practice in humans," says senior study author Leonardo G. Cohen (@LeonardoGCohen) ...

CHICAGO --- Some leaders in health care have called for an end to annual health check visits, saying they're a waste of time for patients and overworked primary care physicians and don't reduce the risk of death. A new Northwestern Medicine study found while there is no clear proof that regular check-ups help adults live longer or prevent cardiovascular events like heart attacks or strokes, they still have many health benefits - especially for at-risk populations - and should continue. Routine check-up visits (they don't have to necessarily be done annually) ...

Decisions made now will determine whether economies win or lose money as the coal industry changes over the next couple of decades. Countries including Australia and Indonesia could lose billions of dollars if they continue to invest in new coal mines and exports as the world moves away from fossil fuels. These are the conclusions of a new analysis led by a team from Imperial College London and including researchers from Queen Mary University of London and Deloitte, which is published today in the journal Joule. The team combined data on coal resources and demand in an economic model of trade and prices. ...

BOSTON -- Death rates from chronic conditions like lung disease and cardiovascular disease and so-called "diseases of despair" such as opioid overdoses are known to be higher in rural areas than in large cities, with differing economic, social and political circumstances influencing people's access to care. To examine disparities in mortality rates for all causes of death, researchers from Brigham and Women's Hospital used a Centers for Disease Control and Prevention (CDC) database to analyze all deaths occurring in the U.S. between 1999 and 2019. They found that age-adjusted mortality rates (AAMRs) declined in both rural and urban populations, but that the gap between the death rates dramatically widened as white individuals aged 25 to ...

Amyotrophic lateral sclerosis (ALS) is a severe, fatal neurodegenerative disorder causing loss of motor neurons and voluntary muscle action. While mouse studies have identified potential treatments, these drugs have typically done very poorly in human trials. Researchers at Boston Children's Hospital, working in collaboration with Pfizer, now report a high-throughput target and drug discovery platform using motor neurons made from ALS patients. Using the platform, they confirmed two known targets and identified an existing class of drugs -- agonists to the dopamine D2 receptor -- as potential novel treatments. The researchers, led by Clifford Woolf, MD, PhD, director of the F.M. Kirby Neurobiology Center at Boston Children's, and first authors Xuan Huang, PhD, and Kasper Roet, PhD, ...

A multidisciplinary team led by researchers from the Spanish Research Council (CSIC) identifies the genomic cellular map associated with hippocampal sclerosis, a major histopathological condition of temporal lobe epilepsy. The study, published in Cell Reports, identifies cell-type specific transcriptional signatures of hyper-excitability and neurodegeneration, providing grounds for improved diagnosis. While the presence of sclerosis is essential for identifying temporal lobe epilepsy (the most common form of drug-resistant epilepsy), it is also detected in some cases of dementia associated ...

Since March 2020 the Cancer Genomics and BioComputing of Complex Diseases Laboratory at the Azrieli Faculty of Medicine of Bar-Ilan University has been dedicated to the study of COVID-19. Motivated in particular to study the evolution of coronaviruses, the lab, led by Dr. Milana Frenkel-Morgenstern, has characterized and compared sequences of numerous relevant viruses. In their most recent study, published in the journal of the Federation of European Biochemical Societies (FEBS), the research team focused on patterns of genetic coding used by viruses which infect a single or narrow range of hosts compared to those which infect a multiple or broad range of hosts. It was discovered that "promiscuous", or multiple-host, viruses utilize significantly non-optimal codons (the DNA ...

Mobility analyses show: Only a small proportion of all vehicles are responsible for the majority of the kilometers driven. We are talking above all about long-distance trucks that transport goods all over Europe. If these continue to be fueled with fossil energy, it will hardly be possible to sufficiently reduce CO2 emissions in road traffic. Synthetic fuels from surplus renewable electricity can make a significant contribution to such frequent driver applications. With electric mobility, hydrogen mobility and synthetic fuels, Empa's future mobility demonstrator, "move", is investigating ...

In a first-of-its-kind study, researchers from Tel Aviv University and the Academic College of Tel Aviv-Yaffo used smart watches and a dedicated app to monitor 169 subjects before and during Israel's second COVID-19 lockdown (October 2020). The watches and app provided the researchers with accurate daily data for measuring quality of life parameters, such as mood, stress, duration and quality of sleep, heart rate at rest, meeting others and physical exercise. The study was conducted by a group of experts from the Iby and Aladar Fleischman Faculty of Engineering at Tel Aviv University led by Dr. Erez Shmueli, Dr. Dan Yamin, Shay Oved and Merav Mofaz, in collaboration with TAU's Prof. Noga Kronfeld Schor of the School of Zoology at the George S. Wise ...

BOSTON - Last year, people who smoked had a variety of responses to the COVID-19 pandemic, with some increasing their smoking to help them cope and others quitting to potentially lessen their vulnerability to COVID-19. That's the finding of new research published in the Journal of General Internal Medicine and conducted by investigators at Massachusetts General Hospital (MGH), Vanderbilt University Medical Center and the University of Pittsburgh School of Medicine. "Studies have shown that alcohol and opioid use increased during the pandemic, but little is known about how smokers responded," says lead author Nancy A. Rigotti, MD, director of MGH's Tobacco Research and Treatment Center and professor of Medicine at Harvard Medical School. "They might have increased ...

Rising temperatures are increasingly affecting the quality of life in many regions, setting new challenges for architects, urban planners and healthcare systems. Researchers at KAUST have analyzed discomfort due to outdoor heat across Saudi Arabia and neighboring regions to help understand and combat the problem. "Living conditions in the Kingdom have been particularly affected by the changing climate," says Hari Dasari, first author of the paper. He also emphasizes the unique challenges facing the Hajj pilgrimage visits by several million people each year. Between 2014 and 2018, the Hajj occurred in summer months when the ...

UNF archaeology researchers are uncovering the lost Indigenous NE Florida settlement of Sarabay Jacksonville, Fla. - The University of North Florida archaeology team is now fairly confident they have located the lost Indigenous northeast Florida community of Sarabay, a settlement mentioned in both French and Spanish documents dating to the 1560s but had not been discovered until now. The type and amounts of Indigenous pottery the team is finding combined with the type and dates for European artifacts as well as cartographic map evidence strongly supports this location as the late 16th/early 17th century Mocama settlement. The researchers have opened large excavation blocks with many exciting ...

The "miracle of life" is most obvious at the very beginning: When the fertilized egg cell divides by means of furrows into blastomeres, envelops itself in an amniotic sac, and unfolds to form germ layers. When the blastomeres begin to differentiate into different cells - and when they eventually develop into a complete organism. "We wanted to find out whether the later differences between the various cells are already partly hard-wired into the fertilized egg cell," says Dr. Jan Philipp Junker, who heads the Quantitative Developmental Biology Lab at the ...

Researchers from Skoltech and Ludwig Maximilians-Universität (LMU) in Germany have studied the fundamental properties of halide perovskite nanocrystals, a promising class of optoelectronic materials. Using a combination of theory and experiment, they were able to show and explain an intricate connection between composition, light-induced lattice dynamics, and stability of the materials. The paper was published in the journal Nature Communications. Perovskite nanocrystals (PNCs) are semiconductor nanocrystals that, thanks to their unique properties, have found a number of applications in optoelectronics, for instance, in lasers and LEDs. PNCs have a much higher photoluminescence quantum ...

Accelerated cognitive decline in patients with and without existing dementia is one of the most disturbing outcomes of hospitalizations for older adults, affecting at least 2.6 million Americans every year. But the condition, known as delirium, is believed to be preventable in up to 40 percent of hospital-acquired cases, and researchers at UC San Franciso wanted to see if simple tweaks, like avoiding nighttime interruptions to promote sleep, nixing certain prescription drugs, and promoting exercise and social engagement, could decrease its incidence. In a June 8, 2021, study in the Journal of Hospital Medicine, the researchers followed approximately 22,700 inpatients aged 50 and ...

MELVILLE, N.Y., June 8, 2021 -- As face coverings have become more and more ubiquitous during the coronavirus pandemic, their effects on nearly every aspect of life have been called into question. For one, a better understanding of the impacts of face masks and shields on acoustic transmission in classrooms could help optimize educational settings. During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Laura and Rich Ruhala, from Kennesaw State University, will talk about how various types of face coverings may affect ...

MELVILLE, N.Y., June 8, 2021 -- In a disaster, time is of the essence when searching for potential victims who may be difficult to find. Unmanned aerial vehicles make the perfect platform for state-of-the-art technology allowing emergency crews to find those in need and provide situational awareness over a large area. During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Macarena Varela, from Fraunhofer FKIE, will describe how a system using an array of microphones and advanced processing techniques could be a lifesaver for disaster victims. The session, "Bearing Estimation of Screams Using a Volumetric Microphone Array Mounted on a UAV," will take place Tuesday, June 8, at 10:35 a.m. Eastern U.S. During ...

Variants of viruses, such as that causing COVID-19, can now be quickly studied in the laboratory, even before they emerge in nature and become a major public health challenge. The University of Queensland, QIMR Berghofer Medical Research Institute, Peter Doherty Institute for Infection and Immunity, Monash University, and Queensland Health have developed a technology to manipulate viruses synthetically allowing rapid analysis and mapping of new potential virus variants. UQ's lead researcher Professor Alexander Khromykh said the technology was ideal for use during a global pandemic such as COVID-19. "This technique should give us the ability to answer questions about whether potential virus variants are susceptible to a particular drug or vaccine, even before they emerge ...

Blue whales may be the biggest animals in the world, but they're also some of the hardest to find. Not only are they rare (it's estimated that less than 0.15 per cent of blue whales in the Southern Hemisphere survived whaling), they're also reclusive by nature and can cover vast areas of ocean. But now, a team of scientists led by UNSW Sydney are confident they've discovered a new population of pygmy blue whales, the smallest subspecies of blue whales, in the Indian Ocean. And it was the whales' powerful singing - recorded by underwater bomb detectors - that gave them away. "We've found a whole new group of pygmy blue whales right in the middle of the Indian Ocean," says UNSW Professor Tracey Rogers, marine ecologist and senior author of the study. "We ...

MINNEAPOLIS/ST. PAUL (06/08/2021) -- New research from the University of Minnesota Medical School and colleagues at the Mayo Clinic reveals a possible new approach to preventing death and severe disease in elderly people infected with SARS-CoV-2. The researchers demonstrated in a preclinical study that senolytic drugs significantly reduced mortality upon infection from a beta-coronavirus closely related to SARS-CoV-2 in older mice. The study published in Science was co-led by Laura Niedernhofer, MD, PhD and Paul Robbins, PhD, both professors in the Department of Biochemistry, Molecular Biology and Biophysics and co-directors of the Institute on the Biology of Aging and Metabolism at the ...

A new tool developed by the University of Cordoba, in collaboration with the Nuclear Medicine Unit at the Hospital Reina Sofía, could allow healthcare personnel to diagnose different degrees of Parkinson's, a disease that, according to World Health Organization (WHO) data, affects 7 million people worldwide. To date, according to AYRNA group researcher Javier Barbero, "most diagnoses only determine whether or not the patient suffers from this disease." The research team has developed a system that makes it possible to specify the phase it is in, distinguishing between four different ones, based on severity. Specifically, this new methodology ...

New molecules, developed by researchers at Linköping University, have promising properties as possible drugs against epilepsy. A study published in the journal Epilepsia shows that several of the molecules have antiseizure effects. In people with epilepsy, the nerve cells in the brain become overactive, causing epileptic seizures. "More than 60 million people in the world have epilepsy. A third of them still experience seizures despite taking medication, so there is a pressing need for new types of drugs", says Nina Ottosson, principal research engineer in the Department of Biomedical and Clinical Sciences, Linköping ...
