Philadelphia, March 23, 2021 - Researchers from Children's Hospital of Philadelphia (CHOP) have discovered that a widely used nutritional supplement may significantly reduce the risk of fatal strokes caused by a rare genetic disorder. Additionally, the findings suggest that the supplement could be used to both block precipitation of and break up the formation of amyloid plaque deposits, a common feature found in serious forms of dementia. The findings were published online today by the journal Nature Communications. The findings centered around a genetic disorder known as hereditary cystatin C amyloid angiopathy (HCCAA). HCCAA is part ...

Evolution of auroral substorms revealed by physicists at University of Warwick using the same methods that link people through social media 'If you like this magnetometer, you might like this one too:' historical data from magnetometers used to match them with 'like-minded friends' during 41 substorms Shows that a single coherent electrical current, that accompanies the Northern Lights during substorms, covers most of the Earth's night-side at high latitudes Will help to validate models used to predict auroral substorms, which can disrupt electronics and power distribution systems Space weather often manifests as substorms, where a beautiful auroral display such as the Northern Lights is accompanied ...

A pioneering study, published in Scientific Reports, found that the Parkinon's gene PINK1 is important for the generation of dopamine-producing neurons throughout life, and is not just responsible for the premature death of these neurons The international research, led by University of Sheffield's Neuroscience Institute, used two model systems to examine how neurons are produced throughout our lifetime Parkinson's disease is a relentlessly progressive neurodegenerative disorder that affects around 145,000 people in the UK A gene defect linked to Parkinson's disease may not only cause the early death of neurons, ...

Hennigsdorf/Berlin, Germany, March 23, 2021 - Diagnostics company SphingoTec GmbH ("SphingoTec") announced today the first published data (1) on the biomarker DPP3 that can predict the evolution of organ function and survival in septic patients. Measured on top of routinely used standard parameters, such as Lactate and Procalcitonin, DPP3 is an early indicator of short-term outcomes and patient severity. Sepsis is a medical emergency caused by a dysregulated host response to an infection, with mortality rates increasing rapidly for each hour that appropriate treatment is delayed (2). The rapid evolution of sepsis into its severe form, septic shock, raises the need for more precise and faster testing to support better clinical decision-making. DPP3 is an ...

Researchers from the Department of Orthopedics of Tongji Hospital at Tongji University in Shanghai have successfully used a nanobiomaterial called layered double hydroxide (LDH) to inhibit the inflammatory environment surrounding spinal cord injuries in mice, accelerating regeneration of neurons and reconstruction of the neural circuit in the spine. The researchers were also able to identify the underlying genetic mechanism by which LDH works. This understanding should allow further modification of the therapy which, in combination with other elements, could finally produce a comprehensive, clinically applicable system for spinal cord injury relief in humans. The ...

Researchers at the University of Toronto have found that food industry interactions with government heavily outnumbered non-industry interactions on Bill S-228, also known as the Child Health Protection Act, which died in the Senate of Canada in 2019. The researchers looked at more than 3,800 interactions, which included meetings, correspondence and lobbying, in the three years before the bill failed. They found that over 80 per cent were by industry, compared to public health or not-for-profit organizations. They also found that industry accounted for over 80 per cent of interactions with the highest-ranking government offices, including elected parliamentarians and their staff and unelected ...

BINGHAMTON, NY -- When it comes to local government, does the gender of a mayor or county executive matter in sustainability policymaking? Yes, but only in certain ways, according to new research from Binghamton University, State University of New York. Kristina Lambright, associate professor of public administration, and George Homsy, associate professor of public administration and director of the environmental studies program, explored the correlation between female leadership and local government adoption of sustainability policies in "Beyond community characteristics: a leader's gender and local government adoption of energy conservation practices and redistributive programmes," published recently ...

Researchers at Chalmers University of Technology, Gothenburg, Sweden, have developed a novel type of thermometer that can simply and quickly measure temperatures during quantum calculations with extremely high accuracy. The breakthrough provides a benchmarking tool for quantum computing of great value - and opens up for experiments in the exciting field of quantum thermodynamics. A key component in quantum computers are coaxial cables and waveguides - structures which guide waveforms, and act as the vital connection between the quantum processor, and the classical electronics which control it. Microwave pulses travel along the waveguides to the quantum processor, and are cooled ...

Incorporating Black churches and clergy in COVID-19 vaccination education and distribution has been found to be an effective model in helping to increase vaccination delivery to historically at-risk populations in San Bernardino County, a study says. Focused education efforts and an on-site mobile clinic in Black church parking lots resulted in the vaccinations of 417 people, 84% of whom were Black. The study also found an increase in Black attendance of mass vaccination clinics to 3.6% of total patients, up from 3%, in the week post-initiative. Researchers at Loma Linda University School of Pharmacy published their findings on March 10 in The Lancet Global Health, ...

Almost 90 percent of infectious travelers could be detected with rapid SARS-CoV-2 tests at the airport, and most imported infections could be prevented with a combination of pre-travel testing and a five-day post-travel quarantine that would only lift with a negative test result, according to a computer simulation by UC San Francisco researchers. The study offers much-needed data to airlines and states that have struggled through a year of the pandemic with little guidance on how to enable safe travel. The issue is becoming more pressing as states ...

Root-knot nematodes (RKNs, Meloidogyne spp.) infect a broad range of plants, including several agriculturally important species such as cotton, soybean and corn, as well as various vegetables and ornamentals. These parasites cause roots to develop galls that result in severe plant damage and, ultimately, important crop losses. Growers currently use synthetic nematicides to manage RKNs; however, these compounds are detrimental to the microbial diversity of soil and harmful for the environment. Thus, it is necessary to develop alternative sustainable control methods. "We have been seeking natural compounds that activate plant defense ...

A cast of so-called 'nurse cells' surrounds and supports the growing fruit fly egg during development, supplying the egg -- or 'oocyte' -- with all the nutrients and molecules it needs to thrive. Long viewed as passive in this process, the Drosophila egg actually plays an active role not only in its own growth, but also in the growth of the surrounding nurse cells, Princeton University researchers report on March 21 in Developmental Cell. "Here we show an example of bidirectional communication -- a dialogue -- between different cells. The egg is taking an active hand in controlling its own feeding ...

Scientists from the Department of Physiology of the University of Granada (UGR) have shown that caffeine (about 3 mg/kg, the equivalent of a strong coffee) ingested half an hour before aerobic exercise significantly increases the rate of fat-burning. They also found that if the exercise is performed in the afternoon, the effects of the caffeine are more marked than in the morning. In their study, published in the Journal of the International Society of Sports Nutrition, the researchers aimed to determine whether caffeine--one of the most commonly-consumed ergogenic substances in ...

LAWRENCE -- When a franchise buys a superstar like Tom Brady or LeBron James, the team tends to win more games. But do the fans follow? How much team loyalty is purchased along with an expensive star? Maybe not as much as some owners might hope -- in the NBA Finals between the Miami Heat and San Antonio Spurs, many fans expressed their dislike of the "bought" Miami team. In a new paper published in the peer-reviewed Journal of Applied Social Psychology, researchers at the University of Kansas asked over 1,500 Americans how much they liked teams that purchased excellence and compared that with liking teams that built excellence from the ground up. "People reliably ...

An international team of scientists from Nanyang Technological University, Singapore (NTU Singapore), Brown University and the Massachusetts Institute of Technology (MIT) has developed an artificial intelligence (AI) platform that could one day be used in a system to assess vascular diseases, which are characterised by the abnormal condition of blood vessels. The AI-powered platform combines machine learning and a specially-designed microfluidic chip with analysis of 2D video images of blood flow and the application of physical laws, to infer how blood flows in 3D. In tests, it accurately predicted blood flow characteristics such as speed, pressure, and shear stress, ...

The world needs more electricity. As populations grow, standards of living increase and more people gain access to modern conveniences, countries will need to expand their energy generation capacity. India, with its rapidly developing economy and a population of more than 1.3 billion, epitomizes this trend. The country finds itself at a crossroads regarding its energy future: Small decisions today will resound in the coming years. In their latest report, the Indian government set a target of 450 gigawatts of renewable energy capacity by 2030. For comparison, the country's total energy generation capacity today is about 380 gigawatts, out of which 90 gigawatts are of renewable energy, not including large hydropower stations. How this plan shapes up will dictate how ...

(BOSTON) -- A team of nanobiotechnologists at Harvard's Wyss Institute for Biologically Inspired Engineering and the Dana-Farber Cancer Institute (DFCI) led by Wyss Founding Core Faculty member William Shih, Ph.D., has devised a programmable DNA self-assembly strategy that solves the key challenge of robust nucleation control and paves the way for applications such as ultrasensitive diagnostic biomarker detection and scalable fabrication of micrometer-sized structures with nanometer-sized features. Using the method, called "crisscross polymerization", the researchers can initiate weaving ...

One of the surest signs of spring is the vibrantly lime-green tinge trees develop as their buds open and tiny new leaves unfurl. Bud-break is the scientific name for this process -- a straightforward term for the grand genetic mechanism that allows trees to leaf out and do their summer work of photosynthesis to store up energy for the coming winter. Bud-break is precluded by bud-set, which occurs in the autumn. After trees have dropped their leaves and as the days shorten and grow colder, new buds grow on branches. Like many wildflowers, trees require a period of dormancy at colder temperatures -- a process fine-tuned by evolution ...

DURHAM, N.C. -An unfortunate biological "feed-forward" loop drives cartilage cells in an arthritic joint to actually contribute to progression of the disease, say researchers at Duke University and Washington University in Saint Louis. Pain researcher and mechanobiologist Wolfgang Liedtke, a professor of neurology at Duke, partnered with former Duke colleague and cartilage expert Farshid Guilak, now at the Washington University School of Medicine, to examine the activity of pressure-sensitive ion channels in cartilage. Their study appears the week of March 22 in the Proceedings of the National Academy of Sciences. Cartilage is the highly lubricated, low-friction, elastic tissue that lines ...

There are 12 essential attributes that explain why commercial carbon capture and sequestration projects succeed or fail in the U.S., University of California San Diego researchers say in a recent study published in Environmental Research Letters. Carbon capture and sequestration (CCS) has become increasingly important in addressing climate change. The Intergovernmental Panel on Climate Change (IPCC) relies greatly on the technology to reach zero carbon at low cost. Additionally, it is among the few low-carbon technologies in President Joseph R. Biden's proposed $400 billion clean energy plan that earns bipartisan support. In the last two decades, private industry and government have ...

Amsterdam, NL, March 22, 2021 - The COVID-19 pandemic has had a profound impact on our world, with disequilibrium, uncertainty, and human suffering making it difficult to envision a human, societal and individual future. Milan Zeleny, PhD, Professor Emeritus of Management Systems, Fordham University, New York, NY, USA, and world-recognized authority on decision making, productivity, knowledge management, and more recently the corporation as a living organism, says that "COVID-19 is rapidly changing from a cause to one of the symptoms of an increasingly unhinged world." Writing in the journal Human Systems Management, published ...
