Since ancient times,
the health benefits of green tea have been the stuff of legend. Now,
researchers are turning to the antioxidant-rich leaves for a decidedly modern purpose
— triggering cell-based therapies.
In a study published Wednesday in Science Translational Medicine, a team of researchers with East China Normal University and First Affiliated Hospital of Shenzhen University found that green tea can work to activate lab-made cells for disease ...read more

Before sending the first woman and next man to the moon, NASA will send a golf cart-sized rover to the lunar south pole to search for sources of ice water. The space agency hopes to have the rover exploring the moon’s surface by December 2022.
The new spacecraft was announced Friday at the International Astronautical Congress, a yearly conference where ...read more

Flame retardants are everywhere. They’re embedded in your TV, your couch — even your child’s car seat. For years, a group of flame retardants was added to a host of consumer products in the U.S. before scientists realized their potentially toxic effects. And now, the old class has been mostly swapped out for a new group that may be just as toxic — and even more widespread — as the chemicals they were created to replace

Our universe’s history began about 13.8 billion years ago with the Big Bang. When astronomers probe deep into space, they see parts of the universe as they were early in this history. That's because it takes light a long time to travel vast distances. To find out how galaxies formed and evolved over time, astronomers look for t ...read more

Every year, a forest of bull kelp springs up from the ocean floor along 200 miles of California coast, fostering a regenerated, thriving ecosystem each time it appears.
But starting in 2013, this kelp forest suffered hits from several disasters. First, a mysterious and lethal disease cropped up among starfish in the area. Then, a massive heat wave stunted kelp growth. In just four years, over 90 percent of this stretch of kelp ...read more

Some of the biggest names in the aerospace industry are teaming up with Amazon and Blue Origin founder Jeff Bezos to create the Human Landing System (HLS), which will bring humans back to the lunar surface by 2024 as part of NASA’s Artemis program.
The announcement at the International Astronautical congress named ...read more

From one end to another, this giant geode is about as long as a small RV. If you wanted, you could comfortably house several adults within its dazzling interior. And the crystalline slabs that jut from its walls may even be taller than you are.
However you slice it, the geode of Pulpí is absolutely gigantic. The interior of the egg-shaped cavity — which measures 25 feet long, 7 feet wide and about 5 feet tall — is encrusted with shimmering cryst ...read more

Researchers report that they've taught rats to drive cars, knocking human technical superiority down another notch.
It's not quite as amazing as it sounds, of course. The "cars" are simple wheeled platforms controlled by means of electrically conductive bars. And the rats aren't quite navigating the Nurburging Nordschleife yet. But the feat hints at the adaptive skills of these common lab animals, and it could lead to new kinds of te ...read more

The larger the spiral galaxy, the faster it spins. That's a well-known fact for astronomers. But a few years ago, researchers discovered a new class of jumbo-sized spiral galaxies. Astronomers call them "super spirals."
And in a surprise find published in The Astrophysical Journal Letters, researchers now say that these super spirals are actually rotating even faster than predicted based on the visible sizes of the galaxies. The fast ...read more

An archaeological excavation begun 125 years ago has wrapped up with a fascinating discovery: A Roman-era street connecting two religious destinations in Jerusalem was likely built by Pontius Pilate.
Researchers were able to date the 720 feet of uncovered road to about A.D. 30, thanks to coins found along the pavement. That lines up w ...read more
