Existing UV light technology has potential to reduce Covid-19 transmission indoors
A recent study has shown that a UV light technology already used to prevent the spread of other airborne diseases in buildings has the potential to be effective against Covid-19. The research, published in the journal PeerJ, found that upper room UV germicidal irradiation (UVGI) can kill SARS-CoV-2 virus particles, which can be transmitted by […]
Orcas blamed for disappearance of S.Africa great white sharks
The numbers of great white sharks in the waters around Cape Town have steeply declined Killer whales are suspected to be behind the disappearance of great white sharks off Cape Town’s coast over the last few years, according to a report published by South Africa’s government on Tuesday. The vanishing of great whites from the […]
Physicists discover the ‘Kings and Queens of Quantumness’
Is that light particle more like a ball careening through space, or more of a smeary mess that is everywhere at once? The answer depends on whether the absurd laws of subatomic particles or the deterministic equations that govern larger objects hold more sway. Now, for the first time, physicists have found a way to […]
Sensor experts invent supercool mini thermometer — ScienceDaily
Researchers at the National Institute of Standards and Technology (NIST) have invented a miniature thermometer with big potential applications such as monitoring the temperature of processor chips in superconductor-based quantum computers, which must stay cold to work properly. NIST’s superconducting thermometer measures temperatures below 1 Kelvin (minus 272.15 ?C or minus 457.87 ?F), down to […]
Saving historical landmarks from climate change could mean altering them
Venice lands among the top example of international treasures that are buckling under climate change. But there are plenty of places that could use the same attention.

With global travel […]
Potential therapeutic strategy for obesity
Obesity is a serious global health problem and a risk factor for diseases such as type II diabetes, heart disease and fatty liver disease. A central element in the development of obesity is adipose tissue, which comprises fat cells (so-called adipocytes, specialised to store fat) and macrophages (immune system scavenger cells, which are typically associated […]
COVID-19 highlights risks of wildlife trade
Market store in Cambodia. A reduction in the interaction between people, wildlife and livestock along with effective protection of habitats and wildlife, is the only way to reduce the risk of future zoonoses like Covid-19 Credit: Kit Magellan Many diseases, such as COVID-19, have made the jump from animals to people with serious consequences for […]
Cretaceous cold case of ‘dueling’ T. rex and Triceratops may finally be solved
The “Dueling Dinosaurs” fossils — the 67 million-year-old remains of what may be the most complete Tyrannosaurus rex and Triceratops on record, beasts that were possibly locked in combat when they died — are finally spilling their secrets. The iconic fossils are heading to the North Carolina Museum of Natural Sciences (NCMNS), where a cutting-edge […]
Adult language learning changes hemisphere specialization for comprehension but not production — ScienceDaily
Learning a language later in life changes how the two halves of the brain contribute. As skills improve, language comprehension changes hemisphere specialization, but production does not, according to new research published in JNeurosci. The two sides of the brain don’t evenly split labor for every function. In most people, language relies on the left […]
Europe Targets 100 Climate-Neutral Cities by 2030
More people are moving to cities. Some forecasts predict that two thirds of the world’s population will live in urban areas by the middle of the century, and in Europe that figure may be 84%. Recognizing the need to act quickly, the European Union (EU) is launching a mission to reach 100 climate-neutral […]
