Coordination polymers (CPs) composed of organic radicals have been the focus of much research attention in recent years due to their potential application to a wide variety of next-generation electronics, from more flexible devices to 'spintronics' storage of information. Sadly, they often suffer from their limited stability and poor crystallinity. Researchers from Japan's Institute for Molecular Science (IMS), National Institute of Natural Sciences (NINS) have developed a novel recipe that not only produces a stable material, but offers a variety of other useful attributes. Their findings appear in the journal ...

The 2020 COVID-19 pandemic is creating a viral archive, an archaeological record of history in the making. One aspect of this archive is increased environmental pollution, not least through discarded face-masks and gloves, collectively known as PPE, that characterise the pandemic. These items of plastic waste have become symbolic of the pandemic and have now entered the archaeological record, in particular face-masks. In the UK alone, 748 million items of PPE, amounting to 14 million items a day, were delivered to hospitals in the two or so months from ...

Researchers believe they may have discovered a possible cause of a mystery condition that can leave sufferers suddenly unable to walk, talk or see. It's hoped the study - led by the University of York and Hull York Medical School and supported by Tees, Esk and Wear Valley NHS Trust - will pave the way for new treatments for Conversion disorder which affects around 800,000 people in the UK alone. The condition, also known as functional neurological disorder (FND), causes physical symptoms that would appear neurological but doctors can't find an injury or physical condition to explain them. Professor Christina van der Feltz-Cornelis from the Department of Health Sciences is leading the Conversion And Neuro-inflammation ...

Two-thirds of 1,120 healthcare workers surveyed worldwide would separate mothers and babies with a positive or unknown COVID-19 status. Implementing Kangaroo Mother Care and keeping mothers and babies together could save more than 125,000 newborn lives, representing 65x decreased risk of newborn death compared to the risk of newborn deaths from COVID-19. New research underscores the need for decision-makers and providers, particularly in LMICs, to protect and strengthen care for small and sick newborns during the pandemic. The COVID-19 pandemic is affecting the quality of care given to small and sick newborn babies in all regions of the world and threatening implementation of life-saving interventions, ...

In Switzerland about 17 000 people are living with an HIV infection, worldwide there are about 38 million. Today, the disease can be treated so successfully that a normal life can be ensured to a great extent. However, weight increases are often observed at the beginning of HIV therapy due to adaptations of the metabolism, which are part of a successful therapy. Therefore, body weight control plays an important role in HIV therapy. It is important, for example, to avoid metabolic problems that can lead to heart attacks or diabetes over the long term. Tenofovir is the drug used as part of the standard HIV therapies. The previously, widely used TDF-based therapy (tenofovir disoproxil fumarate, TDF) has been associated with renal side effects and ...

An important Maya man buried nearly 1,300 years ago led a privileged yet difficult life. The man, a diplomat named Ajpach' Waal, suffered malnutrition or illness as a child, but as an adult he helped negotiate an alliance between two powerful dynasties that ultimately failed. The ensuing political instability left him in reduced economic circumstances, and he probably died in relative obscurity. During excavations at El Palmar, a small plaza compound in Mexico near the borders of Belize and Guatemala, archaeologists led by Kenichiro Tsukamoto, an assistant professor of anthropology at UC Riverside, discovered a hieroglyph-adorned stairway ...

(Boston)-- Newly published National Institute of Neurological Disorders and Stroke (NINDS) Consensus Diagnostic Criteria for Traumatic Encephalopathy Syndrome (TES) are the first expert consensus criteria developed for the clinical disorder associated with Chronic Traumatic Encephalopathy (CTE) brain pathology. CTE is a degenerative brain disease associated with a history of repetitive head impacts, including those sustained in contact and collision sports such as American football and boxing. At this time, CTE can only be diagnosed after death through a neuropathological examination of brain tissue. There has been no accepted approach or agreed upon criteria for the diagnosis of CTE and its clinical manifestations during life until now. "The publication of these criteria ...

Exercise during pregnancy may let mothers significantly reduce their children's chances of developing diabetes and other metabolic diseases later in life, new research suggests. A study in lab mice has found that maternal exercise during pregnancy prevented the transmission of metabolic diseases from an obese parent - either mother or father - to child. If the finding holds true in humans, it will have "huge implications" for helping pregnant women ensure their children live the healthiest lives possible, the researchers report in a new scientific paper. This means that one day soon, a woman's first trip to the doctor after conceiving might include a prescription for an exercise ...

The $1.9 trillion American Rescue Plan, a stimulus package introduced by the Biden Administration, recently received Congress' approval. The stimulus package, like its two predecessors aimed at providing relief for individuals and businesses hindered by the COVID-19 pandemic, includes another round of funding for the Paycheck Protection Program (PPP). The American Rescue Plan includes $7.25 billion for PPP loans as well as a number of changes to make it easier for the smallest of businesses to gain access to the funding. With billions on the table for struggling small businesses, new research from the University of Florida Warrington College of ...

How important is fame? What about self-acceptance? Benevolence? The messages children between the ages of 8 and 12 glean from TV play a significant role in their development, influencing attitudes and behaviors as they grow into their teenage years and beyond, UCLA psychologists say. Now, a new report by UCLA's Center for Scholars and Storytellers assesses the values emphasized by television programs popular with tweens over each decade from 1967 to 2017, charting how 16 values have waxed and waned in importance during that 50-year span. Among the key findings is that fame, after nearly 40 years of ranking near the bottom (it was 15th in 1967, 1987 and 1997), rose to become the No. 1 ...

Louisiana State University researchers recently published findings that blight leads to an increased abundance of disease-carrying mosquitoes. The researchers investigated the presence of several mosquito species in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge: the historic Garden District, a high-income neighborhood, and the Old South neighborhood, a low-income area. They found significantly higher adult and larvae abundance of the Asian tiger mosquito (a carrier of Zika and dengue) and higher mosquito habitat availability--particularly discarded tires--in the Old South neighborhood. This indicates that environmental conditions in the low-income neighborhood were most ideal for this mosquito to breed and proliferate. "These ...

Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a study led by the University of California, Davis. The study, published today in the journal PNAS, chronicles the effort --and failure -- to eradicate invasive European green crabs from a California estuary. The crabs increased 30-fold after about 90 percent had been removed. The study is the first experimental demonstration in a coastal ecosystem of a dramatic population increase in response to full eradication. "A failure in science often leads to ...

The world's oceans are a vast repository for gases including ozone-depleting chlorofluorocarbons, or CFCs. They absorb these gases from the atmosphere and draw them down to the deep, where they can remain sequestered for centuries and more. Marine CFCs have long been used as tracers to study ocean currents, but their impact on atmospheric concentrations was assumed to be negligible. Now, MIT researchers have found the oceanic fluxes of at least one type of CFC, known as CFC-11, do in fact affect atmospheric concentrations. In a study appearing today in the Proceedings of the National Academy of Sciences, the team reports that the global ocean will reverse its longtime role as a sink for the potent ozone-depleting chemical. The researchers ...

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland--and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017. In 2019, University of Vermont scientist Andrew Christ looked at it through his microscope--and couldn't believe what he was seeing: twigs and leaves instead of just sand and rock. That suggested that the ice was gone in the recent geologic past--and that a vegetated landscape, perhaps a boreal forest, stood where a mile-deep ice sheet as big ...

For the first time, researchers have pinpointed what causes normal proteins to convert to a diseased form, causing conditions like CJD and Kuru. The research team, from Imperial College London and the University of Zurich, also tested a way to block the process, which could lead to new drugs for combatting these diseases. The research concerned prion diseases - a group of brain diseases caused by proteins called prions that malfunction and 'misfold', turning into a form that can accumulate and kill brain cells. These diseases can take decades to manifest, but are then are aggressive and fatal. They include Kuru, mad cow disease and its human equivalent Creutzfeldt-Jakob disease (CJD), and a heritable condition called fatal familial ...

If you live in a flood prone area, would you -- or could you -- take measures to mitigate flood risks? What about others in your community? We are running out of time to ask this question according to The World Resources Institute, because global flood risk is increasing and loss projections for rivers alone put the cost over 500 billion dollars by midcentury. Research published today in Proceedings of the National Academy of Sciences from scientists from the University of Connecticut, the University of Maryland's National Socio-Environmental Synthesis Center (SESYNC), the University of Massachusetts Amherst, and the London School of Economics suggests that in the United States, race and stream flow are ...

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term. BMMFs and inflammatory markers were significantly more frequently detectable in the vicinity of malignant intestinal tumors than in the intestinal tissue of tumor-free individuals. A few years ago, ...

Researchers developed a prototype for a new cancer immunotherapy that uses engineered T cells to target a genetic alteration common among all cancers. The approach, which stimulates an immune response against cells that are missing one gene copy, called loss of heterozygosity (LOH), was developed by researchers at the Ludwig Center, Lustgarten Laboratory and the Bloomberg~Kimmel Institute for Cancer Immunotherapy at the Johns Hopkins Kimmel Cancer Center. Genes have two alleles, or copies, with one copy inherited from each parent. Cancer-related genetic alterations commonly involve the loss of one of these gene copies. "This copy loss, or LOH, is one of the most common genetic events in cancer," says Kenneth Kinzler, Ph.D., co-director of the Ludwig Center, professor of oncology and ...

HOUSTON - (March 15, 2021) - Increased internet-access spending by Texas public schools improved academic performance but also led to more disciplinary problems among students, a study of 9,000 schools conducted by a research team from Rice University, Texas A&M University and the University of Notre Dame shows. Whether students benefit from increased internet access in public schools has been an open question, according to the researchers. For example, some parents and policy advocates contend it increases children's access to obscene or harmful content and disciplinary problems. Others believe it promotes personalized learning and higher student engagement. To address these policy questions, the research team created a multiyear dataset (2000-14) of 1,243 school districts ...

When Steamboat Geyser, the world's tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can we learn about it before it goes quiet again? The University of Utah has been studying the geology and seismology of Yellowstone and its unique features for decades, so U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring. The findings are published in the Journal of Geophysical Research-Solid Earth. "We ...

If you are a consumer and/or entrepreneur who can make decisions based on cost, competition, supply and demand, you probably possess an element of marketplace literacy. "Marketplace literacy" is defined as the knowledge and skills that enable individuals to participate in a marketplace both as consumers and entrepreneurs. San Diego State University marketing professor Nita Umashankar, along with professors Madhubalan Viswanathan (Loyola Marymount University), Arun Sreekumar (University of Illinois at Urbana Champaign) and Ashley Goreczny (Iowa State University), explored the impact on marketplace literacy on ...

HSE University researchers together with specialists from the Humanitarian Action Charitable Fund (St. Petersburg) and the University of Michigan School of Public Health (USA) studied the specifics of remote work with Russian people who use drugs to reduce the harm of drug use. They discovered that the use of online platforms increases the § who use drugs to seek help. Online platforms also serve as a kind of 'gateway' for people with problematic drug use to receive a wider range of qualified help. The authors concluded that remote work in this field should be developed and built upon in ...

Forest landscape restoration is attaining new global momentum this year under the Decade of Ecosystem Restoration (2021-2030), an initiative launched by the United Nations. Burkina Faso, in West Africa, is one country that already has a head start in forest landscape restoration, and offers valuable lessons. An assessment of achievements there and in other countries with a history of landscape restoration is critical to informing a new wave of projects aiming for more ambitious targets that are being developed thanks to renewed global interest and political will to improve the environment. Burkina Faso has been fighting with desertification and climate change, and has seen a progressive degradation of its forested landscapes due to the expansion of agriculture. In 2018, the country ...

In the last 20 years, Black adults living in rural areas of the United States experienced high mortality rates due to diabetes, high blood pressure, heart disease and stroke compared to white adults. According to a research letter published in the Journal of the American College of Cardiology, racial disparities improved minimally in rural areas over the last two decades, with larger improvements occurring in urban areas. "While modest gains have been made in reducing racial health inequities in urban areas, large gaps in death rates between Black and white adults persist in rural areas, particularly for diabetes and hypertension. We haven't meaningfully ...
