Fast radio bursts, or FRBs, blaze for a few milliseconds before vanishing without a trace. Their origins are unknown, and their appearance is unpredictable. In the decade following their discovery in 2007, only 140 FRBs had been seen. Now, thanks to the launch of a large stationary telescope in the interior of British Columbia in 2018, the number of new FRBs detected has almost quadrupled - for a total of 535. Moreover, the Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB), a McGill-led inter-university collaboration, has put together the first CHIME/FRB catalogue, which will be presented this week at the American Astronomical Society Meeting. CHIME is unique in that ...

Recently, a research team led by Prof. ZHAO Bangchuan from the Institute of Solid Materials of the Hefei Institutes of Physical Science (HFIPS) synthesized 3D porous honeycomb-like CoN-Ni3N/N-C nanosheets and vanadium nitride (VN) nanobelt arrays via in-situ growth method, respectively, and constructed a high-energy-density flexible supercapacitor device. The result has been published in Advanced Functional Materials. Transition metal nitrides (TMNs) are potential electrode materials for high-performance energy storage devices, but the structural instability severely hinders their application. Therefore ...

Ikoma, Japan - "If you can't stand the heat, get out of the kitchen," as the old saying goes. But for organisms that can't leave the proverbial kitchen when things get too hot, there's another way: researchers from Japan have discovered that plants can gain heat tolerance to better adapt to future heat stress, thanks to a particular mechanism for heat stress 'memory'. In a study published in Nature Communications, researchers from Nara Institute of Science and Technology have revealed that a family of proteins that control small heat shock genes enables plants to 'remember' how to deal with heat stress. Climate change, especially global warming, is a growing threat to agriculture ...

Prostate cancer is the most common form of cancer among Canadian men and the third leading cause of cancer death. Abdominal obesity appears to be associated with a greater risk of developing aggressive prostate cancer. This link was demonstrated in a END ...

Generally, physics and financial systems are not easily associated in people's minds. Yet, principles and techniques originating from physics can be very effective in describing the processes taking place on financial markets. Modeling financial systems as networks can greatly enhance our understanding of phenomena that are relevant not only to researchers in economics and other disciplines, but also to ordinary citizens, public agencies and governments. And the theory of Complex Networks represents a powerful framework for studying how shocks propagate in financial systems, identifying early-warning signals of forthcoming crises, and reconstructing ...

Today the Hamburg-based Cluster of Excellence "Climate, Climatic Change, and Society" (CLICCS) publishes a new, essential study on climate futures. The study represents the first systematic attempt to investigate whether a climate future with net-zero carbon emissions is not only possible but also plausible. The authors examine plausibility from a technical-economic perspective, but also with regard to the societal changes necessary for such a future. They conclude that deep decarbonization by 2050 is currently not plausible - the current efforts to bring about societal transformation need to be far more ambitious. The European Union is now increasing the ambition of its climate goals, and the German Federal Constitutional Court has recently committed Germany ...

Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products. The researchers, from the University of Cambridge, created a polymer film by mimicking the properties of spider silk, one of the strongest materials in nature. The new material is as strong as many common plastics in use today and could replace plastic in many common household products. The material was created using a new approach for assembling plant proteins into materials which mimic silk on a molecular level. The energy-efficient method, which uses sustainable ingredients, results in a plastic-like free-standing film, which can be made at industrial ...

Researchers from North Carolina State University have turned a longstanding challenge in DNA data storage into a tool, using it to offer users previews of stored data files - such as thumbnail versions of image files. DNA data storage is an attractive technology because it has the potential to store a tremendous amount of data in a small package, it can store that data for a long time, and it does so in an energy-efficient way. However, until now, it wasn't possible to preview the data in a file stored as DNA - if you wanted to know what a file was, you had to "open" the entire file. "The advantage to our technique is that it is more efficient ...

DALLAS, June 10, 2021 -- The distance a stroke patient must travel to receive care at a certified stroke center differs by race, age, income and insurance status, with the largest disparities found among rural residents and American Indians, according to a combined analysis of U.S. census data and road maps published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association. Treatment for ischemic stroke, a blockage in an artery that supplies blood to the brain, restores blood flow to the brain. Rapid treatment is essential to reduce disability. Blood flow may be reestablished by administering intravenous clot-busting medication within 4.5 hours after the onset of stroke ...

Polymetallic nodules and crusts cover many thousands of square kilometres of the world's deep-sea floor. They contain valuable metals and rare earth elements and are therefore of great economic interest. To date, there is no market-ready technology for deep-seabed mining. But it is already clear that interventions in the seabed have a massive and lasting impact on the areas affected. This is also confirmed by a study now published by Tanja Stratmann from the Max Planck Institute for Marine Microbiology in Bremen, Germany, and researchers from the Senckenberg am Meer Institute in Wilhelmshaven, Germany, and the Dutch research institute NIOZ. In their study, Stratmann and her colleagues used data from ...

When nature vanishes, people of color and low-income Americans disproportionally lose critical environmental and health benefits--including air quality, crop productivity and natural disease control--a new study in Nature Communications finds. The University of Vermont research is the first national study to explore the unequal impacts on American society--by race, income and other demographics--of projected declines in nature, and its many benefits, across the United States. Focusing on three vital ecosystem services--air quality, crop pollination, and control of insect-borne disease (West Nile virus), researchers project that these benefits of nature will decrease for non-white people by an average of 224%, ...

Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone? In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives. To learn more about this project, we talked to lead author Dr. Orad Reshef, a senior postdoctoral fellow in the Robert Boyd Group, and research lead Dr. Jeff Lundeen, who is the Canada Research Chair in Quantum Photonics, Associate Professor in the ...

A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone." A new study by UCLA researchers suggests that those drugs, commonly known as MAOIs, might have another health benefit: helping the immune system attack cancer. Their findings are reported in two papers, which are published in the journals Science Immunology and Nature Communications. "MAOIs had not been linked to the immune system's response to cancer before," said Lili Yang, senior author of the study and a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. "What's especially exciting is that this is a very well-studied and ...

The largest study of its kind has unveiled new insights into how genes are regulated in dementia, including discovering 84 new genes linked to the disease. Led by the University of Exeter, the international collaboration combined and analysed data from more than 1,400 people across six different studies, in a meta-analysis published in Nature Communications. These studies had used brain samples from people who had died with Alzheimer's disease. The project, funded by Alzheimer's Society and supported by the Medical Research Council and the National Institutes for ...

UNIVERSITY OF TORONTO & CARLETON UNIVERSITY New research published online in the journal Substance Use & Misuse is good news for those struggling with alcohol dependence: the possibility of ending this dependency gets easier with age. Moreover, more than half of individuals who have been dependent on alcohol are free of any addictions or mental illness, and nearly 40% are in excellent mental health. Using data drawn from Statistics Canada's Canadian Community Health Survey-Mental Health, researchers examined a nationally representative sample of 820 adult Canadians with a history of alcohol dependence to 19,945 who had never been addicted to alcohol. They found that in the past year, 71% of ...

PISCATAWAY, NJ - Underage youth consumed $17.5 billion worth, or 8.6 percent, of the alcoholic drinks sold in 2016. Products from three alcohol companies--AB Inbev, MillerCoors and Diageo--accounted for nearly half of youth consumption, according to a new study published in the Journal of Studies on Alcohol and Drugs. Data collected in a landmark study of youth alcohol consumption by brand enabled the authors to calculate the first estimate in nearly 20 years of the monetary value of youth alcohol consumption. And for the first time, they were able to attribute those revenues to specific companies. "The alcohol industry has said they don't want minors to drink, ...

ROCHESTER, Minn. -- Treating transplant patients with mild to moderate cases of COVID-19 with monoclonal antibodies is safe and helps prevent serious illness, according to a Mayo Clinic study recently published in Open Forum Infectious Diseases. These results are especially important because transplant patients who are infected with COVID-19 have a higher risk of severe illness and death. "Monoclonal antibody therapy is really important for the transplant population because they are less likely to develop their own immunity. Providing them with these antibodies helps them recover from COVID-19," says Raymund Razonable, M.D., a Mayo Clinic infectious diseases specialist and the study's senior ...

When herring are filleted, more than half their weight becomes a low-value 'side stream' that never reaches our plates - despite being rich in protein and healthy omega-3 fatty acids. Now, scientists from Chalmers University of Technology, Sweden, have developed a special dipping solution, with ingredients including rosemary extract and citric acid, which can significantly extend the side streams' shelf life, and increase the opportunities to use them as food. Techniques for upgrading these side-streams to food products such as minces, protein isolates, hydrolysates and oils are already available today, and offer the chance to reduce the current practices of using them for animal feed, ...

For over a century, researchers have known about "the bends", a serious condition affecting scuba divers. However, we still know relatively little about its physiological basis. Doctors do not yet have a definitive test for the bends, instead relying on symptoms to diagnose it. A new study in Frontiers in Physiology is the first to investigate genetic changes in divers with this condition, finding that genes involved in inflammation and white blood cell activity are upregulated. The findings cast light on the processes underlying the bends, and may lead to biomarkers that will help doctors to diagnose the condition more precisely. The bends, more formally known as decompression sickness, is a potentially lethal condition that can affect divers. Symptoms ...

BOSTON -- Obesity increases one's risk for many diseases and often prevents patients from receiving other necessary medical procedures. One of the most effective ways for patients with severe obesity to lose weight is through bariatric surgery, but it's not clear how often this option is raised. In a new study published in Obesity, investigators from Brigham and Women's Hospital find that eligible patients who discuss bariatric surgery options with their primary care providers or specialists from disciplines ranging from cardiology to urology are more likely to undergo surgery and lose more weight than ...

Previous studies have shown that children with attention difficulties and/or ADHD solve cognitive tasks better when they are exposed to auditory white noise. However, this is the first time that such a link has been demonstrated between visual white noise and cognitive abilities such as memory, reading and non-word decoding in children with reading and writing difficulties. "The white noise to which we exposed the children, also called visual pixel noise, can be compared with giving children glasses. The effect on reading and memory was immediate," explains Göran Söderlund, Senior Lecturer in Education at the University of Gothenburg and Professor of Special Education at the Western Norway University ...

People who are more prone to boredom and who are socially conservative are more likely to break public-health rules, according to new psychology research. While previous research demonstrated a connection between being highly prone to boredom and breaking social-distancing rules, this study demonstrated the association was more prominent as participants' social conservatism increased. "Many public-health measures such as wearing a mask or getting a vaccine have become highly politicized," said James Danckert, professor of psychology at the University of Waterloo. "People who find these ...

PITTSBURGH, June 10, 2021 - Americans are consuming more craft beer with higher alcohol content but are drinking less beer by volume, according to a new analysis led by epidemiologists at the University of Pittsburgh Graduate School of Public Health. The study, published online and in a coming issue of the journal Substance Use & Misuse, looked at beer purchased in stores between 2004 and 2014. This is the first study to examine trends not only in the volume of beer purchased, but also the "beer specific" alcohol content. "With the rise in popularity of craft breweries and the acquisition of such breweries by large-scale ...

India's national government has inappropriately prioritised people for covid-19 vaccination Current approach is causing huge numbers of avertable deaths, warn experts India's national government has inappropriately prioritised people for covid-19 vaccination, argue doctors and researchers in The BMJ today. Peter Lloyd-Sherlock and colleagues warn that the government's current approach to vaccination - focusing on younger age groups - "is causing huge numbers of avertable deaths and is deeply inequitable." From 3 May to 5 June 2021, more first doses were administered to people under 45 than over 60, even though at ...

HOUSTON -- Results from the multi-cohort Phase I/II ARROW clinical trial, conducted by The University of Texas MD Anderson Cancer Center researchers, showed that a once-daily dose of pralsetinib, a highly selective RET inhibitor, was safe and effective in treating patients with advanced RET fusion-positive non-small cell lung cancer (NSCLC) and RET-altered thyroid cancer. The findings for each cohort were published today in The Lancet Oncology and The Lancet Diabetes & Endocrinology, respectively. "Targeted therapies have dramatically improved care for patients with NSCLC and thyroid cancer driven by oncogenes, and the rapid clinical translation of selective RET inhibitor ...
