Earth’s Core May Be Leaking Hydrogen Into the Mantle, a New Study Suggests

Computer simulations from a Chinese team suggest hydrogen has been seeping from Earth’s core into the mantle for billions of years. It is a modeling result, with open questions.

Soil Bacteria Make a “Pac-Man” Enzyme That Eats Bioplastics, and It Can Also Break Down Penicillin

German researchers found a soil-bacteria enzyme with a wide-open active site that breaks down biodegradable plastics and, in lab tests, penicillin. Ordinary polyethylene went almost untouched.

Why Does the Moon Have Two Faces? First Far-Side Rocks Point to Earth’s Pull

Rocks from China's Chang'e-6 mission suggest Earth's gravity heated the young Moon unevenly, pushing crust-building magma to the far side. Here's the evidence, and the catch.

A Fossil That Sat in a Museum Drawer for Nearly 100 Years Is Europe’s First Megaraptor

A skull fragment collected on England’s Isle of Wight and overlooked since 1924 is a new species of claw-handed predator, the first megaraptor confirmed in Europe.

A Canadian Telescope Picks Up the Faint Glow of Hydrogen From 9 Billion Years Ago

The CHIME radio telescope detected a faint signal from hydrogen gas in the distant universe on its own, a step toward mapping cosmic expansion and testing ideas about dark energy.

Physicists Build the First Working Nuclear Clocks, and One Can Keep Itself in Tune

Two teams report the first clocks that tick with an atomic nucleus instead of electrons. A Vienna prototype even stabilizes itself. Here is how they work and what they could mean.

Hubble May Have Spotted a Planet Born After Its Star Died

A 25-year-old Hubble puzzle points to a giant planet that may have formed from a dead star’s leftovers. Astronomers stress it is still only a candidate.

Crew-12 Is Home After 237 Days in Orbit. Here’s What the Mission Did and What Comes Next

NASA’s SpaceX Crew-12 splashed down off Los Angeles on Oct. 8 after 237 days in orbit. Here’s a look at the crew, the spacewalk records, the science and what happens next.

A 2-Million-Year-Old Skull Fragment Is the First Adult Homo Erectus From a Famous South African Cave

A skull fragment from South Africa’s Drimolen cave site is the first adult Homo erectus found there, dated to about 2 million years ago — roughly 200,000 years older than adult fossils from Georgia.

October’s Night Sky: Orionid Meteors, a Bright Saturn and the Full Moon

Halley’s Comet leftovers light up the Orionid meteor shower on October 21–22, while Saturn shines all night. Here’s what to look for and when.

Chemistry Nobel Goes to Two Scientists Who Showed How Molecules Can Amplify Their Own “Handedness”

Henri B. Kagan and Kenso Soai won the 2026 Nobel Prize in Chemistry for discoveries about how mirror-image molecules form, with clues to why life is one-handed.

Nobel Prize in Medicine Goes to the Scientists Who Taught Brain Cells to Respond to Light

Karl Deisseroth, Peter Hegemann and Georg Nagel share the 2026 Nobel Prize in Physiology or Medicine for optogenetics, a technique that uses light to switch specific nerve cells on and off.
