The shift to home working brought about by the pandemic could cost the UK economy up to £32bn a year in lost personal income tax. Highly paid workers who live abroad but work in the UK will pay their income tax in their country of residence, rather than to HMRC - which researchers say could cost billions each year. This new mobility of the workforce can also affect where corporate income tax is paid and value created, as well as VAT and where goods and services are purchased. Professor Rita de la Feria, Chair in Tax Law in the University of Leeds' School of Law, co-led the new research with Dr Giorgia Maffini, Tax Policy expert, at PWC, ...

Legend has it that Marie Antoinette's hair turned gray overnight just before her beheading in 1791. Though the legend is inaccurate--hair that has already grown out of the follicle does not change color--a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons is the first to offer quantitative evidence linking psychological stress to graying hair in people. And while it may seem intuitive that stress can accelerate graying, the researchers were surprised to discover that hair color can be restored when stress is eliminated, a finding that contrasts with a recent study in mice that suggested that stressed-induced gray hairs are permanent. The ...

WOODS HOLE, Mass. -- It's cold in the depths of the world's oceans; most of the seafloor is at a chilly 4°C. Not so the seafloor of Guaymas Basin in the Gulf of California. Here, tectonic plates drift apart and heat from Earth's interior can rise up -- so far up that it bakes large areas of the seafloor sediments, turning buried organic matter into methane and other energy-rich compounds. What kinds of organisms thrive in this oceanic hotspot? In two new studies, MBL Assistant Scientist END ...

Looking for better ways to treat patients with esophageal cancer, University of Colorado Cancer Center member Martin McCarter, MD, is investigating whether a new treatment sequence will result in better outcomes. As they await the results of a group of clinical trials -- including one at the CU Cancer Center -- McCarter and other University of Colorado researchers (led by surgery resident Bobby Torphy, MD, PhD) looked at data from the National Cancer Database to see if they could identify other patients who have undergone the new sequence, and what the outcomes for those patients were. The group published a paper in the Annals of Surgical Oncology in April ...

Rainfall associated with the Intertropical Convergence Zone (ITCZ), the belt of converging trade winds and rising air that encircles the Earth near the Equator, affects the food and water security of approximately 1 billion people worldwide. They include about 11% of the Brazilian population, concentrated in four states of the Northeast region - Rio Grande do Norte, Ceará, Piauí, and Maranhão. Large swathes of these states have a semi-arid climate, and about half of all their annual rainfall occurs in only two months (March and April), when the tropical rain belt reaches its southernmost position, over the north of the Northeast region. During the rest of the year, the tropical ...

(SACRAMENTO, Calif.) -- The secret to healthier skin and joints may reside in gut microorganisms. A study led by UC Davis Health researchers has found that a diet rich in sugar and fat leads to an imbalance in the gut's microbial culture and may contribute to inflammatory skin diseases such as psoriasis. ...

New research published in the Journal of Medicinal Food suggests eating prunes each day can improve risk factors for cardiovascular disease (CVD) including raising antioxidant capacity and reducing inflammation among healthy, postmenopausal women. Cardiovascular disease is the number one cause of death worldwide posing a significant public health challenge. The research led by San Diego State University reveals that prunes can positively affect heart disease risk. "When you look at our prior research and the research of others combined with this new data, you'll see consistent ...

"Workforce issues are the most significant challenges facing the long-term care industry," states the opening editorial of a new special issue of The Gerontologist titled " END ...

Almost all cells in our body contain a nucleus: a somewhat spherical structure that is separated from the rest of the cell by a membrane. Each nucleus contains all the genetic information of the human being. So it serves as a kind of library - but one with strict requirements: If the cell needs the building instructions for a protein, it won't simply borrow the original information. Instead, a transcript of it is made in the nucleus. The machinery required for this is very complex, not least because the transcripts are not simple copies. In addition to essential information, genes also contain numerous passages of meaningless "garbage". They are removed when the transcript is made. Biologists call this editorial revision ...

Persons suffering from the autoimmune disease multiple sclerosis can develop various neurological symptoms caused by damage to the nervous system. Especially in early stages, these may include sensory dysfunction such as numbness or visual disturbances. In most patients, MS starts with recurring episodes of neurological disability, called relapses or demyelinating events. These clinical events are followed by a partial or complete remission. Especially in the beginning, the symptoms vary widely, so that it is often difficult even for experienced doctors to interpret them correctly to arrive at a diagnosis of MS. Above-average numbers of medical appointments It has been evident for some ...

The most comprehensive molecular study to date of the brains of people who died of COVID-19 turned up unmistakable signs of inflammation and impaired brain circuits. Investigators at the Stanford School of Medicine and Saarland University in Germany report that what they saw looks a lot like what's observed in the brains of people who died of neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease. The findings may help explain why many COVID-19 patients report neurological problems. These complaints increase with the severity of infection with SARS-CoV-2, the virus that causes COVID-19. And they can persist as an aspect of "long COVID," a long-lasting disorder that sometimes ...

If only it were as simple as finding more grassland for an antelope. The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there. On its surface, like many threatened species, you have conflict between a need for habitat and private landownership. But dig a little deeper and you'll uncover a seedy underbelly of political corruption, gambling, struggles over land, and racial tensions. No matter how much success is made through more traditional conservation efforts, says a new study by a University of Georgia researcher, the species ...

Rutgers scientists have used a diagnostic technique for the first time in the opioid addiction field that they believe has the potential to determine which opioid-addicted patients are more likely to relapse. Using an algorithm that looks for patterns in brain structure and functional connectivity, researchers were able to distinguish prescription opioid users from healthy participants. If treatment is successful, their brains will resemble the brain of someone not addicted to opioids. "People can say one thing, but brain patterns do not lie," said Suchismita Ray, lead researcher and an associate professor in the Department of Health Informatics at Rutgers School of Health Professions. "The brain patterns that ...

Cancer cells can become resistant to treatments through adaptation, making them notoriously tricky to defeat and highly lethal. Cold Spring Harbor Laboratory (CSHL) Cancer Center Director David Tuveson and his team investigated the basis of "adaptive resistance" common to pancreatic cancer. They discovered one of the backups to which these cells switch when confronted with cancer-killing drugs. KRAS is a gene that drives cell division. Most pancreatic cancers have a mutation in the KRAS protein, causing uncontrolled growth. But, drugs that shut off mutant KRAS do not stop the proliferation. ...

Lifestyle changes for demand-side climate change mitigation is gaining more and more importance and attention. A new IIASA-led study set out to understand the full potential of behavior change and what drives such changes in people's choices across the world using data from almost two billion Facebook profiles. Modern consumption patterns, and especially livestock production in the agricultural sector to sustain the world's growing appetite for animal products, are contributing to and speeding the advance of interconnected issues like climate change, air pollution, and biodiversity ...

Imagine flexible surgical instruments that can twist and turn in all directions like miniature octopus arms, or how about large and powerful robot tentacles that can work closely and safely with human workers on production lines. A new generation of robotic tools are beginning to be realized thanks to a combination of strong 'muscles' and sensitive 'nerves' created from smart polymeric materials. A research team led by the smart materials experts Professor Stefan Seelecke and Junior Professor Gianluca Rizzello at Saarland University is exploring fundamental aspects of this exciting field of soft robotics. In the factory of ...

As well as bright colours and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar, according to scientists at the Universities of Bristol and Exeter. This new research has shown that bumblebees are able to accurately detect and choose between flowers that have different levels of humidity next to the surface of the flower. The study, published this week in the Journal of Experimental Biology, showed that bees could be trained to differentiate between two types of artificial flower with different levels of humidity, if only one of the types of flower provided the bee with a reward of sugar water. To make sure that the artificial flowers ...

Augmented reality (AR) is poised to revolutionise the way people complete essential everyday tasks, yet older adults - who have much to gain from the technology - will be excluded from using it unless more thought goes into designing software that makes sense to them. The danger of older adults falling through the gaps has been highlighted by research carried out by scientists at the University of Bath in the UK in collaboration with designers from the Bath-based charity Designability. A paper describing their work has received an honourable mention at this year's Human Computer Interaction Conference (CHI2021) - the world's largest conference of its kind. The ...

According to a recent study, open learning spaces are not directly associated with the physical activity of students in grades 3 and 5, even though more breaks from sedentary time were observed in open learning spaces compared to conventional classrooms. The findings are based on the CHIPASE study, carried out at the Faculty of Sport and Health Science of the University of Jyväskylä. The results were published in Frontiers of Sports and Active Life. After the reform of the national core curriculum for basic education in Finland, issued in 2016, most of the new or renovated comprehensive schools in Finland began to incorporate ...

The way in which a compound inspired by nature produces hydrogen has now been described in detail for the first time by an international research team from the University of Jena, Germany and the University of Milan-Bicocca, Italy. These findings are the foundation for the energy-efficient production of hydrogen as a sustainable energy source. Nature as a model There are naturally occurring microorganisms that produce hydrogen, using special enzymes called hydrogenases. "What is special about hydrogenases is that they generate hydrogen catalytically. Unlike electrolysis, which ...

The relationship between personality, genes and chronotype (sleep patterns) has been studied by researchers at the University of Warwick and the University of Tartu, Estonia People high in Conscientiousness and low in Openness are rather morning people; lower-level personality traits such as self-discipline, excitement-seeking, and straightforwardness have also been linked to chronotype It is partly due to genetic factors, but there is scope to change your sleep patterns if you wanted to become a morning person but are currently an evening person for example The link between the different hierarchies of personality, sleep patterns and even genetics has been discovered by ...

Coastal wetlands like seagrass meadows, mangroves, and salt marshes play vital roles along the shoreline, from providing a buffer against storm surges, to providing critical habitat for animals, to capturing atmospheric carbon. We are still just beginning to comprehend the intricate workings of these highly productive ecosystems and their role in mitigating the climate crisis, but UConn researchers are one step closer to understanding how salt marsh vegetation, their bacterial communities, and vegetation can help predict a marsh's potential to be a blue carbon reservoir. The research was recently published in the journal Estuaries and Coasts. "Coastal marshes are increasingly recognized as important ecosystems because they sequester and store a lot of carbon. There is ...

Most of us have genetic variations that increase the risk of medicinal products not being effective. In order to provide a more effective treatment with fewer side effects, we need to analyse more of these genetic variations. This will provide us with more precise knowledge about how the individual patient reacts to medicinal products. A new research result from Aarhus University shows that. Personalised medicine has been a hot topic in recent years, using information about the genes to adapt the treatment to the individual patient. Personalised medicine potentially provides better treatment and fewer side effects for the patient. At least in ...

WASHINGTON, June 22, 2021 -- About 2.2 billion people globally lack reliable access to clean drinking water, according to the United Nations, and the growing impacts of climate change are likely to worsen this reality. Solar steam generation (SSG) has emerged as a promising renewable energy technology for water harvesting, desalination, and purification that could benefit people who need it most in remote communities, disaster-relief areas, and developing nations. In Applied Physics Letters, by AIP Publishing, Virginia Tech researchers developed a synthetic tree to enhance SSG. SSG turns solar energy into heat. Water from a storage ...

A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines in both humans and domesticated animals. These are volatile substances that contribute to the typical odor of many vegetables or are formed when food is heated. In addition, pyrazines also play a role as signaling substances in intra- or interspecific communication. The new research results contribute to a better understanding of the molecular mechanisms underlying the odor perception ...
