Light pollution drives increased risk of West Nile virus

Florida has experienced a relatively mild winter, which typically translates to more mosquitoes in the summer and more birds on which they can feast. If history repeats itself, it's likely there will be an uptick in West Nile virus cases this year, especially in the outer fringes of the suburbs where much of the nighttime illumination emanates from the skyglow of nearby cities.

Snappy evolution was behind the success of ancient crocodiles

New research led by the University of Bristol has revealed that crocodiles once flourished on land and in the oceans as a result of fast evolution.

Individual SARS-CoV-2 neutralizing antibody immunity lasts from days to decades

Scientists from Duke-NUS Medical School, the National Center for Infectious Diseases (NCID) and the Agency for Science, Technology and Research (A*STAR) Infectious Diseases Labs found that antibodies against SARS-CoV-2 wane at different rates, lasting for mere days in some individuals, while remaining present in others for decades. The study, published in The Lancet Microbe, shows that the severity of the infection could be a deciding factor in having longer-lasting antibodies. Individuals with low levels of neutralizing antibodies may still be protected from COVID-19 if they have a robust T-cell immunity.

Novel thermometer can accelerate quantum computer development

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 strong coffee half an hour before exercising increases fat-burning

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.

People have started to care about insects. Now we need action, say experts

"If you had asked me this question four years ago, I would have given you a totally different answer."

Parkinson's gene may impair how new neurons are made throughout our lifetime

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 neuronsThe international research, led by University of Sheffield's Neuroscience Institute, used two model systems to examine how neurons are produced throughout our lifetimeParkinson's disease is a relentlessly progressive neurodegenerative disorder that affects around 145,000 people in the UKA gene defect linked to Parkinson's disease may not only cause the early death of neurons, but also impair the process that generates neurons in the brain throughout our lifetime, a new study has revealed.

Researchers find supplement prevents strokes in patients with rare genetic disorder

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.

Algorithms inspired by social networks reveal lifecycle of substorms, a key element of space weather

Space weather often manifests as substorms, where a beautiful auroral display such as the Northern Lights is accompanied by an electrical current in space which has effects at earth that can interfere with and damage power distribution and electrical systems. Now, the lifecycle of these auroral substorms has been revealed using social media-inspired mathematical tools to analyse space weather observations across the Earth's surface.

New result from the LHCb experiment challenges leading theory in physics

The LHCb Collaboration at CERN has found particles not behaving in the way they should according to the guiding theory of particle physics—the Standard Model.

China's Baidu debuts in Hong Kong after $3.1 bn IPO

Chinese search engine Baidu debuted on Hong Kong's stock exchange Tuesday after raising $3.1 billion in its initial public offering, the latest mainland tech giant to flock to the financial hub.

'Catastrophic' Australia floods prompt helicopter rescues

Military helicopters, jet skis and rubber boats were deployed to rescue people stranded by "catastrophic" floods along Australia's populous east coast Tuesday, with thousands of homes damaged.

AstraZeneca may have included 'outdated' data in US vaccine trials: regulator

AstraZeneca may have included out-of-date drug data in information provided during US trials for its COVID-19 vaccine, a regulator said late Monday, citing concerns from a monitoring board.

Germany extends virus lockdown till mid-April as cases rise

Germany has extended its lockdown measures by another month and imposed several new restrictions, including largely shutting down public life over Easter, in an effort to drive down the rate of coronavirus infections.

US weather model upgraded to better forecast extreme events

The National Weather Service has turbocharged its lagging forecast model to better predict extreme weather events such as hurricanes, blizzards and downpours, as well as day-to-day weather.

Partnership with churches increases COVID-19 vaccine delivery among Black population

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.

Study outlines testing strategies for safer air travel during the pandemic

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.

A leader's gender plays a role in local government sustainability policymaking

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.

Food industry lobbying was intense on failed bill to limit marketing to Canadian children

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.
