Three respiratory viruses are straining families and hospital systems right now. Here’s advice from infectious-disease experts.

Secret ingredients make up 86% of the product, including fragrances. Because the EPA does not require companies to release what’s in fragrances, little is known about what chemicals are in this product.

By the 2A030s, the world will generate around a yottabyte of data per year — that’s 1024 bytes, or the amount that would fit on DVDs stacked all the way to Mars. Now, the booming growth of the data sphere has prompted the governors of the metric system to agree on new prefixes beyond that magnitude, to describe the outrageously big and small.

It is precisely oriented to the sunrise of the winter solstice, in such a way that the sun's rays bathed with its light the place that was intended to house the statue of a governor of the city of Elephantine, who lived at the end of the XII Dynasty, around 1830 BC.

Pairs coalesce into triads, quintuplets, and suddenly the entire forest is pulsating with a common, glittering beat. The swarm has reached synchrony.

Cheese is not just a tasty snack — it’s an ecosystem. And the fungi and bacteria within that ecosystem play a big part in shaping the flavor and texture of the final product.

Reactions to the science of global warming have followed a similar course to those of other inconvenient truths from physics.

Two physicists have calculated that the universe has a higher entropy — and is therefore more likely — than alternative possible universes. The calculation is “an answer to a question that is yet to be fully understood.”

These earliest galaxies were nothing like present-day galaxies in which star formation is confined to small regions, such as the constellation of Orion in our own Milky Way galaxy.

The findings bode well for the capability of JWST to conduct the broad range of investigations on exoplanets — planets around other stars — scientists hoped for. That includes probing the atmospheres of smaller, rocky planets like those in the TRAPPIST-1 system.

Astronomers saw a telltale signature of shock waves shooting along a jet.

The crewless Orion capsule, part of the Artemis I mission, flew within 81 miles of the lunar surface as it headed into the next stage of its journey.

Space chiefs are to investigate whether electricity could be beamed wirelessly from orbit into millions of homes.

Nobody knows for sure, but the accepted theory is that the Earth acts like a dynamo.

The worst of the worst included a coal-fired power plant in Alabama, a coal mine in Pennsylvania and a nylon plant in Florida, recent EPA data shows.

“The U.S. provides transmission owners little incentive to deliver more power over existing lines or to reduce transmission congestion,” the DOE report said.

Against huge odds and with minimal resources, farmers and peasant agrarian communities around the globe are proving we can nourish people and the planet with agro-ecological farming.

From loss and damage to 1.5C goal and World Bank reform, the takeaways from Sharm el-Sheikh.
