Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature.

In the U.S., those who consume alcohol and drive are often subjected to roadside stops, breathalyzer tests and stiff penalties if their blood alcohol content exceeds certain limits. Currently, no such test exists for cannabis intoxication, although the substance is known to impair driving, among other activities. Scientists now report that they are one step closer to a convenient saliva test for...

A recent study has found that there is no evidence for or against the use of non-steroidal anti-inflammatory drugs such as ibuprofen for patients with COVID-19.

An artificial intelligence tool accurately predicted which patients newly infected with the COVID-19 virus would go on to develop severe respiratory disease, a new study found.

Genetics researchers say a new approach could benefit all sorts of serious health conditions, and they're urging scientists to quickly pluck 'low hanging fruit' for the benefit of patients.

How much spring and summer affect the COVID-19 pandemic may depend not only on the effectiveness of social distancing measures, but also on the environment inside our buildings, according to a new review on how respiratory viruses are transmitted.

Fair or not, airplanes have a reputation for germs. However, there are ways to minimize the risks. This research is especially used for air travel where there is an increased risk for contagious infection or disease, such as the recent worldwide outbreak of the coronavirus, which causes COVID-19 disease.

Tropical forests are heavily fragmented as they are cleared for agricultural expansion and logging. Forest fragmentation leads to declines in carbon storage beyond just those trees that are cleared—the remaining forest at the edge of each clearing experiences environmental alterations such as increased sunlight and decreased soil moisture that can impact growing conditions for trees. These "edge...

The machine learning techniques scientists use to predict outcomes from large datasets may fall short when it comes to projecting the outcomes of people's lives, according to a mass study led by researchers at Princeton University in a collaboration with researchers across many institutions, including Virginia Tech.

Women have made progress in earning college degrees as well as in pay and in occupations once largely dominated by men since 1970—but the pace of gains in many areas linked to professional advancement has slowed in recent decades and stalled in others, finds a new five-decade analysis.

A new study led by the University of Kent has found evidence that human ancestors as recent as two million years ago may have regularly climbed trees.

Charlotte Pearson's eyes scanned a palm-sized chunk of ancient tree. They settled on a ring that looked "unusually light," and she made a note without giving it a second thought. Three years later, and armed with new methodology and technology, she discovered that the light ring might mark the year that the Thera volcano on the Greek island of Santorini erupted over the ancient Minoan...

Kids are getting a crash course on texting and social media with “technology on training wheels.”

There’s a surreal calm in the last country in Europe to hold out against lockdown. But the death toll is rising and some are voicing dissentCoronavirus – latest updatesSee all our coronavirus coverageThe Øresund Bridge – yes, that bridge – is an engineering marvel linking the Swedish city of Malmö and Copenhagen that normally transports 70,000 people daily. It has fallen eerily silent....

University of Washington researchers are among the leaders of a newly announced clinical trial investigating whether hydroxychloroquine, a drug that's commonly used to counter malaria and autoimmune disease, can prevent COVID-19. The multi-site trial, managed by UW in collaboration with New York University's Grossman School of Medicine, aims to determine definitively whether taking the...

Students struggling to get online in a rural South Carolina county received a boost last week with the arrival of six buses equipped with Wi-Fi, some of the hundreds the state has rolled out since schools were closed by the coronavirus outbreak.

Coughing fits, anxiety and paranoia are three of the most common adverse reactions to cannabis, according to a recent study.

What do chocolate, migratory birds, flood control and pandas have in common? Many countries benefit from ecosystem services provided outside their nations. This can happen through economic relationships, biological and geographical conditions, but we hardly know how and where these ecosystem service flows occur. Scientists at the Helmholtz Centre for Environmental Research (UFZ) and the German...

We live in a time of unprecedented access to information. And in this era of sheltering-in-place around the nation and the globe, the desire for news may be higher than ever—at least for some people. But do we really want all this information, all the time? Some may indeed prefer to think happier thoughts and maintain an (overly) optimistic outlook about the health threat we face. On the other...

Scientists from the German Cancer Research Center (DKFZ) and the Heidelberg Institute of Stem Cell Technology and Experimental Medicine (HI-STEM) and the Max Planck Institute in Freiburg have identified a new control mechanism that enables stem cells to adapt their activity in emergency situations. For this purpose, the stem cells simultaneously modify the blueprints for hundreds of proteins...
