Smartphone apps and wearable devices can tell when workers have been within six feet of each other, promising to help curb the coronavirus. But they’re not all the same when it comes to privacy.
Government policies and dangerous conditions affect the ability of researchers working on both sides of the US-Mexico border to conduct scientific fieldwork.
From its roots as an electric version of snake oil, by the 1930s vibrators were just another household electric appliance that could soothe your pains at the end of a long day.
A new survey finds that Americans are willing to accept limits on visitors to public lands to reduce crowds, and want staff and visitors to wear masks.
Epidemiological data suggests that 80% of COVID-19 cases can be traced to just 20% of those infected with SARS-CoV-2.
As the 31st anniversary of TV’s ‘Seinfeld’ approaches, let’s take a look at what science has to say about its most memorable episodes.
Researchers have discovered the first known example of a hybrid fungus that infects humans.
The chemical weapon, tear gas, was used in Washington DC, Los Angeles, Orlando and several other cities to control crowds protesting the death of George Floyd. But what is it? Does it cause harm?
Differences in the viruses’ biology and societal contexts mean there’s no guarantee today’s pandemic will mirror the ‘waves’ of infection a century ago.
Many respiratory viruses cause us to temporarily lose our sense of smell. But SARS-CoV-2 isn’t like those other viruses. Researchers are now exploring how it differs and whether patients recover.
Scanning through billions of chemicals to find a few potential drugs for treating COVID-19 requires computers that harness together thousands of processors.
Release of GM mosquitoes in Florida is imminent. But a multidisciplinary team of scientists believe that more studies are needed first. They encourage a publicly accessible registry for GM organisms.
Generating energy usually means wasted heat. Semiconductors let the electrons flow with zero waste – but so far scientists only know how to get them to work at ultra-low temperatures.
Mud blister worms make their homes in the shells of oysters and other shellfish, where they weaken their hosts.
Understanding others’ emotions is a crucial social skill. Counter to concerns about screen time stunting kids’ development, one study suggests they’re getting better at recognizing emotion on screen.
Antibodies that recognize and block SARS-CoV-2 infection have the potential to be powerful weapons. An infectious disease expert explains what antibodies are and how they could be used as a therapy.
With caregivers’ faces covered, infants and young children will miss out on all the visual cues they’d normally get during stages of rapid developmental growth.
A new biotech regulation allows companies to self-police and decide which crops should be regulated. The new rule is likely to amplify greater distrust of GM crops.
Mmmmmmm. That smells delicious. Wait, how do you know that?
Computerized systems that automatically determine whether a pitch is a ball or strike promise to make umpiring more accurate, but at what price?
An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
You might have already felt what it would be like inside a cloud made of condensed water vapor.
The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
