CO2 emissions in Los Angeles and the Washington DC/Baltimore regions fell roughly 33% in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study in Geophysical Research Letters led by NIST and NASA. But while the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact.

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy -- and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic 'switch.'

One cohesive, enormous stream of stars extends at least 1,600 light-years -- 500 parsecs -- from tip to tip. A team of astrophysicists led by Princeton University's Luke Bouma used TESS data to show that stars in the core of NGC 2516 (the Southern Beehive) are rotating at the same rate as stars hundreds of light-years away, confirming that they were born in the same stellar nursery.

A study examining gender bias and family-owned businesses found daughters were rarely encouraged nor received support to pursue entrepreneurship education while sons mostly did.

Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island's outstanding capacity to produce record-breaking floods and trigger a large number of landslides.

Novel coronavirus causing COVID-19 uses the enzyme ACE2 to access our cells, and the concentration of ACE2 in the blood can predict whether a coronavirus infection will become life-threatening, new study finds.

In a pre-clinical study that helps settle the debate on the pros and cons of carbs, Australian researchers have found the quality and type of carbohydrates eaten in combination with reduced protein levels severely impacts health outcomes. Researchers at the University of Sydney's Charles Perkins Centre conducted the largest ever study of nutrient interactions by examining the health of mice on 33 different diets containing various combinations of protein to carbs, and different sources of carbohydrate.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a "weighted coin" that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

Researchers at the Finnish Center for Artificial Intelligence have developed a machine learning-based method that produces synthetic data on the basis of original data sets, making it possible for researchers to share their data with one other. This could solve the ongoing problem of data scarcity in medical research and other fields where information is sensitive.

Male mice more susceptible to stress can pass down their behaviors to offspring via changes in their sperm's genetic code, according to new research published in JNeurosci.

Researchers at Queen Mary University of London have tested an algorithm on 700,000 patient records in east London, to find out if the data routinely collected by GPs can reveal cases of Familial Hypercholesterolemia - a leading cause of heart attack in young people.

Understanding how magnetic correlations change over short timescales is the first step in being able to control magnetism for applications.

Many contemporary political conflicts are between those who would prioritize the needs of local or national communities and those with a more universal outlook. According to a new study by IASS researcher Silvia Weko, this split between 'communitarian' and 'cosmopolitan' Europeans is also evident in their attitudes towards European climate policy. Achieving climate neutrality without exacerbating societal divisions within and between countries will require the EU to strike a careful balance.

For years, psychology researchers have treated peer rejection and social network isolation as being somewhat interchangeable when it comes to early adolescence; it was thought that if kids fell into one of those two groups, they fell into the other. A recent study finds there is actually little overlap between the groups -- and socially isolated kids face different risks.

After winning the FIFA World Cup, France could also win the European Football Championship - this is the conclusion of researchers from the Universities of Innsbruck (Austria) and Ghent (Belgium), the Technical Universities of Dortmund and Munich (Germany) and Molde University College (Norway). England and Spain also have a good chance of winning the title, according to the forecast.

Ancient chickens lived significantly longer than their modern equivalents because they were seen as sacred -- not food -- archaeologists have found.

A Dutch-American research team, coordinated by Radboudumc, describes how sleep problems can arise in individuals with neurodevelopmental disorders such as autism and intellectual disability. Mimicking two genetic causes of autism in fruit flies, they uncovered that flies show the same sleep problems as the patients, that the disturbed sleep is caused by high levels of serotonin and that the origin of high serotonin and sleep problems resides on the glial cells of the blood-brain barrier.

An international team of scientists led from the Centre for Astrobiology (CAB, CSIC-INTA), with participation from the Instituto de Astrofísica de Canarias (IAC), has used the Gran Telescopio Canarias (GTC) to study a representative sample of galaxies, both disc and spheroidal, in a deep sky zone in the constellation of the Great Bear to characterize the properties of the stellar populations of galactic bulges.

What's as long a basketball court, taller than a b-double and has just stomped into the record books as Australia's largest dinosaur? It's time to meet Australotitan cooperensis -- a new species of giant sauropod dinosaur from Eromanga, southwest Queensland.

Older Chinese immigrants who adjust to their new cultural environment by learning the language, following the country's media and socializing with local residents can reduce acculturation gap with their adult children and protect their cognitive function, according to a Rutgers study.
