The Centers for Disease Control and Prevention recently issued new guidelines, and other experts have weighed in with their thoughts.

Risks shoot up when virus particles accumulate in buildings, but it’s not clear how best to improve ventilation.

A great account of the many ways our current pandemic has mirrored the one experienced by our forebears a century ago.

Congress, in a rare show of bipartisanship, is gearing up to try to prevent the next pandemic.

the seven-day average of new cases is just under 62,000 cases per day, which marked a nearly 12 percent spike from the prior seven-day period.

Before it became a staple of video-games, the maze was a test of reason and courage, a way to find yourself by getting lost.

Afghans developed this method of food preservation, which uses mud-straw containers and is known as kangina, centuries ago in Afghanistan’s rural north.

The zoo of spontaneously emerging particle-like entities known as quasi-particles has grown quickly and become more and more exotic. Here are a few of the most curious and potentially useful examples.

Generally thought of as fierce horse warriors, the Scythians were a multitude of Iron Age cultures who ruled the Eurasian steppe, playing a major role in Eurasian history.

The science of sourdough bread is anything but run of the mill.

Until now, researchers have believed that dark energy accounted for nearly 70 percent of the ever-accelerating, expanding universe.

Scientists simulate how humans trace patterns in the night sky.

A super-precise experiment at Fermilab is carefully analyzing every detail of the muon’s magnetic moment.

The first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists have greatly improved the ability of complex computer simulations to describe this moment, discovering that a complex network of structures can form in the first trillionth of a second after the Big Bang. These microscopic clumps have masses of only a few grams and fit into volumes much smaller than particles.

A neutrino-spotting telescope beneath the frozen Lake Baikal in Russia is close to delivering scientific results after four decades of setbacks.

We often complain about buildings that are too tall or cars that are too heavy, so it should be no surprise that we might wonder if the Ever Given – the giant container ship that was stuck in the Suez Canal – is too big.

To that effect, Google seeks to make the phone form factor easier to use, most demonstrated by its new Memory feature.

Cloud seeding involves adding small particles of silver iodide to clouds to spur rainfall – but will it work?

The Crown Estate is set to issue leases allowing developers to construct pioneering floating turbines in the Celtic Sea

Scientists have created a microrobot that can pass the near-impenetrable blood-brain barrier to treat brain tumors in mice.

Indoor fitness classes, which often result in heavy breathing in poorly ventilated rooms, can be risky. Here’s a guide to help you decide if your gym is doing enough to prevent the spread of Covid-19.

If you’re interested in trying breathing exercises to reduce stress or anxiety, or improve your lung function, here are 10 different ones to sample.

A dozen major companies earned an F for failing to publicly address the growing problem of toxic chemicals that may be in the products they sell to consumers.

If you reach for water when a muscle cramp strikes, you might want to think again. New research has revealed drinking electrolytes instead of pure water can help prevent muscle cramps.

A nine-month investigation by the Guardian and Consumer Reports found alarming levels of forever chemicals, arsenic and lead in samples taken across the US.

New data indicating that Earth’s surface broke up about 3.2 billion years ago helps clarify how plate tectonics drove the evolution of complex life.

The National Oceanic and Atmospheric Administration said there were 89 right whales spotted in the bay on March 21, including three pairs of mothers and babies.

With NASA preparing to send humans to Mars in the 2030s, researchers are studying the physical effects of spending long periods in space.

The UK’s woods are full of strange specimens. But they aren’t easy to identify – even for the experts.

Their severed heads get around just fine until they regenerate perfectly functioning, parasite-free new bodies, scientists say.

Our species — due largely to rapid population growth and explosive consumption — is destabilizing these Earth processes, endangering the stability of the “safe operating space for humanity.”

To start, the EPA will assess the risks of all uses—known and potential—of a new chemical, and it will mandate necessary protections for workers.

Initiative by Commerce, Energy, Interior and Transportation departments aims to tackle climate change while boosting union jobs

Zero waste lifestyle products will be available in 9 pop-up shops.

The greatest increase in sea level rise during the 2,000-year period beginning in year 1 CE occurred in the last 100 years, from 1900 to 2000.

The record bloom fits into a long-term pattern toward earlier spring flowering, a compelling indicator of climate change, experts say.
