The Covid-19 pandemic is impacting people's mental health. But what helps and hinders people in getting through a lockdown? A new study led by researchers at the University of Basel addressed this question using data from 78 countries across the world. The results hint at the pivots and hinges on which the individual's psyche rests in the pandemic. At the outset of the Covid-19 pandemic, little was known about the impact of population-wide governmental lockdowns. What was known was taken from restricted quarantines of small groups of people. "On the one hand, such drastic changes to daily routines can be detrimental to mental health," explains Professor ...

People view the wolf as either a threatening predator or a sign of a healthy natural habitat. Many proponents of nature and animal conservation welcome the spread of wolf populations in Germany. By contrast, farmers who graze herds directly impacted by the wolves' return are more critical. The team of Nicolas Schoof, Prof. Dr. Albert Reif of the Chair of Site Classification and Vegetation Science at the University of Freiburg, and Prof. Dr. Eckhard Jedicke of the Competence Center Cultural Landscape and the Department of Landscape Planning and Nature Conservation of Hochschule Geisenheim University has assessed the existing legal situation. On the basis of a range of environmental data they have determined the conflicts and drawn up possible solutions. In an article in ...

Northeastern Asia has a complex history of migrations and plague outbursts. That is the essence of an international archaeogenetic study published in Science Advances and lead from the Department of Archaeology and Classical Studies at Stockholm University. Genomic data from archaeological remains from 40 individuals excavated in northeastern Asia were explored in the study. "It is striking that we find everything here, continuity as well as recurrent migrations and also disease-related bacteria", says Anders Götherström, professor at the Center for Palaeogenetics at Stockholm University and one of the Principal investigators of the study. The ...

Sleep is ubiquitous in animals and humans and vital for healthy functioning. Thus, sleep after training improves performance on various tasks in comparison to equal periods of active wakefulness. However, it has been unclear so far whether this is due to an active refinement of neural connections or merely due to the absence of novel input during sleep. Now researchers at the Medical Center - University of Freiburg have succeeded in showing that sleep is more than rest for improving performance. The findings, which were published in the journal SLEEP on January 6, 2021, provide important information for planning periods of intensive ...

January 7, 2021 (BRAMPTON - HAMILTON) -- When dealing with a life-limiting illness, palliative care can improve the quality of life for patients and families. However, for many people, the fear of "end of life" care prevents them from exploring it. A recent study from William Osler Health System (Osler) and McMaster University examined awareness of palliative care in the South Asian community and found that culture plays a critical role in the perception of palliative care. This perception, in turn, affects whether or not patients will be open to receiving it. Funded by a McMaster University, Department ...

TORONTO, January 7, 2021- What feels like up may actually be some other direction depending on how our brains process our orientation, according to psychology researchers at York University's Faculty of Health. In a new study published in PLoS One, researchers at York University's Centre for Vision Research found that an individual's interpretation of the direction of gravity can be altered by how their brain responds to visual information. Laurence Harris, a professor in the Department of Psychology in the Faculty of Health and Meaghan McManus, a graduate student in his lab, found, using virtual reality, that people differ ...

DALLAS - Jan. 7, 2020 - A protein that wreaks havoc in the nerves and heart when it clumps together can prevent the formation of toxic protein clumps associated with Alzheimer's disease, a new study led by a UT Southwestern researcher shows. The findings, published recently in the Journal of Biological Chemistry, could lead to new treatments for this brain-ravaging condition, which currently has no truly effective therapies and no cure. Researchers have long known that sticky plaques of a protein known as amyloid beta are a hallmark of Alzheimer's and are toxic to brain cells. As early as the mid-1990s, other proteins were discovered in these plaques as well. One of these, a protein known as transthyretin (TTR), ...

Brazilian researchers have managed to decipher the structure of a protein found in parasites that cause neglected tropical diseases, paving the way to the development of novel medications. Thanks to the discovery it will be possible to seek more potent molecules capable of destroying the pathogens directly, with fewer adverse side-effects for patients. The study detailed the structural characteristics of the protein deoxyhypusine synthase (DHS), found in Brugia malayi, one of the mosquito-borne parasites that cause elephantiasis, and in Leishmania major, the protozoan that causes cutaneous leishmaniasis. Elephantiasis, also known as lymphatic filariasis, is an infection of the lymph system that can lead to swelling of the legs, arms, and genitalia. It may also harden and ...

HOUSTON - (Jan. 7, 2021) - Proteogenomic analysis may offer new insight into matching cancer patients with an effective therapy for their particular cancer. A new study identifies three molecular subtypes in head and neck squamous cell carcinoma (HNSCC) that could be used to better determine appropriate treatment. The research led by Baylor College of Medicine, Johns Hopkins University and the National Cancer Institute's Clinical Proteomic Tumor Analysis Consortium (CPTAC) is published in the journal Cancer Cell. Researchers profiled proteins, phosphosites and signaling ...

TROY, N.Y. -- In a money-saving revelation for organizations inclined to invest in specialized information technology to support the process of idea generation, new research suggests that even non-specialized, everyday organizational IT can encourage employees' creativity. Recently published in the journal Information and Organization, these findings from Dorit Nevo, an associate professor in the Lally School of Management at Rensselaer Polytechnic Institute, show standard IT can be used for innovation. Furthermore, this is much more likely to happen when the technology is in the hands of employees who are motivated to master technology, understand their role in the organization, ...

In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers from The University of Texas MD Anderson Cancer Center found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease. "Men with prostate cancer are motivated to find a way to impact the advancement of their disease and improve their quality of life," said Justin Gregg, M.D., assistant professor of Urology and lead author of the study, published today in Cancer. ...

Tsukuba, Japan - Does losing weight while you sleep sound too good to be true? According to a study by the University of Tsukuba, it seems that drinking oolong tea might help you do just that. While all tea comes from the same plant, Camellia sinensis, the degree of oxidation, a chemical reaction that turns tea leaves black, defines its specific type. For example, green tea is unoxidized and mild in flavor, while the distinctive color of black tea comes from complete oxidation. Oolong tea, being only partially oxidized, lies somewhere in between and displays characteristics ...

Some people have lost their eyesight, but they continue to "see." This phenomenon, a kind of vivid visual hallucination, is named after the Swiss doctor, Charles Bonnet, who described in 1769 how his completely blind grandfather experienced vivid, detailed visions of people, animals and objects. Charles Bonnet syndrome, which appears in those who have lost their eyesight, was investigated in a study led by scientists at the Weizmann Institute of Science. The findings, published today in Brain, suggest a mechanism by which normal, spontaneous activity in the visual centers of the brain can trigger visual hallucinations in the blind. Prof. Rafi Malach and his group members of the Institute's Neurobiology Department research the phenomenon of spontaneous "resting-state" ...

Research from life-saving charity Air Ambulance Kent Surrey Sussex (KSS) in partnership with the University of Surrey has shown the benefits of dispatching HEMS to patients with a sudden, unexplained LOC of medical origin and a high prevalence of acute neurological pathology. The study - which is believed to be the first published about HEMS dispatch to non-trauma (neuro) cases - also highlights how HEMS dispatchers in dialogue with ambulance personnel are able to select patients requiring HEMS-specific interventions and, based on its findings, identifies opportunities to improve triage for these patients. Through a retrospective study of all patients with a LOC ...

In a study spanning four decades, researchers from the University of Hong Kong's Research Division for Ecology & Biodiversity (HKU) in the Faculty of Science, and Toho University's Department of Biology (Toho), Japan, have discovered that predation by snakes is pushing lizards to be active at warmer body temperatures on islands where snakes are present, in comparison to islands free from snakes. Their work also detected significant climatic warming throughout the years and found lizard body temperatures to have also increased accordingly. The findings show that lizard thermal biology is highly dependent on predation pressures ...

Geneva, Switzerland, 7 January 2021 - 'Mini-brains' are pin-head sized collections of several different types of human brain cell. They are used as a tool, allowing scientists to learn about how the brain develops, study disease and test new medicines. Personalized 'mini-brains' can be grown from stem cells generated from a sample of human hair or skin and could shed light on how brain disease progresses in an individual and how this person may respond to drugs. Research published today by a team of scientists and engineers from HEPIA and the Wyss Center for Bio and Neuroengineering, in the journal Frontiers in Bioengineering and Biotechnology, has revealed ...

Until now, the reason why the drug levodopa (L-Dopa), which reduces the motor symptoms of Parkinson's disease, declines in efficacy after a few years' use has been unknown. A side effect that then often occur is involuntary movements. A Swedish-French collaboration, led from Uppsala University, has now been able to connect the problems with defective metabolism of L-Dopa in the brain. The study is published in Science Advances. "The findings may lead to new strategies for treating advanced Parkinson's," says Professor Per Andrén of the Department of Pharmaceutical Biosciences at Uppsala University. He and Dr Erwan Bézard of the University of Bordeaux, France, headed ...

The coastline of Israel is one of the warmest areas in the Mediterranean Sea. Here, most marine species have been at the limits of their tolerance to high temperatures for a long time - and now they are already beyond those limits. Global warming has led to an increase in sea temperatures beyond those temperatures that Mediterranean species can sustain. Consequently, many of them are going locally extinct. Paolo Albano's team quantified this local extinction for marine molluscs, an invertebrate group encompassing snails, clams and mussels. They thoroughly surveyed the Israeli coastline and ...

Sweden kept preschools, primary and lower secondary schools open during the spring of 2020. So far, little research has been done on the risk of children being seriously affected by COVID-19 when the schools were open. A study from Karolinska Institutet in Sweden has now shown that one child in 130,000 was treated in an intensive care unit on account of COVID-19 during March-June. The study has been published in New England Journal of Medicine. So far, more than 80 million people have become ill with COVID-19 and globally, almost two million people have died from the disease. Many countries have closed down parts of society in order to reduce the spread of infection. One such measure has been to close schools. ...

Men and women aged over 50 can reap similar relative benefits from resistance training, a new study led by UNSW Sydney shows. While men are likely to gain more absolute muscle size, the gains relative to body size are on par to women's. The findings, recently published in END ...

Social media misinformation can negatively influence people's attitudes about vaccine safety and effectiveness, but credible organizations -- such as research universities and health institutions -- can play a pivotal role in debunking myths with simple tags that link to factual information, University of California, Davis, researchers, suggest in a new study. Researchers found that fact-check tags located immediately below or near a post can generate more positive attitudes toward vaccines than misinformation alone, and perceived source expertise makes a difference. "In fact, fact-checking labels ...

An international team of researchers led by Swinburne University of Technology has demonstrated the world's fastest and most powerful optical neuromorphic processor for artificial intelligence (AI), which operates faster than 10 trillion operations per second (TeraOPs/s) and is capable of processing ultra-large scale data. Published in the prestigious journal Nature, this breakthrough represents an enormous leap forward for neural networks and neuromorphic processing in general. Artificial neural networks, a key form of AI, can 'learn' and perform complex operations with wide applications to computer vision, natural language processing, facial recognition, speech translation, ...

El Niño events have long been perceived as a driver for low rainfall in the winter and spring in Hawai'i, creating a six-month wet-season drought. However, a recent study by researchers in the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology (SOEST) revealed the connection between Hawai'i winter rainfall and El Niño is not as straightforward as previously thought. Studies in the past decade suggested that there are at least two types of El Niño: the Eastern Pacific and Central Pacific, when the warmest pool of water is located in the eastern or central portions of the ocean basin, respectively. El Niño events usually ...

WASHINGTON--Black and Hispanic people with COVID-19 and diabetes are more likely than Caucasians to die or have serious complications, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism. ...

With an estimated lifespan between 25 to 40 years, the queen conch (Strombus gigas) is a prized delicacy long harvested for food and is revered for its beautiful shell. Second only to the spiny lobster, it is one of the most important benthic fisheries in the Caribbean region. Unfortunately, the species faces a challenge of survival: how to endure and thrive, as populations are in a steady state of decline from overfishing, habitat degradation and hurricane damage. In some places, the conch populations have dwindled so low that the remaining conch cannot find breeding partners. This dire situation is urgent in ecological and economic terms. To preserve this most significant molluscan fishery in the Caribbean, ...
