50 years ago, mysterious glass hinted at Earth’s violent past

Like Hansel and Gretel followed a trail of breadcrumbs, scientists have followed tektites to the sites of major meteorite impacts.

New fossils from Patagonia may rewrite the history of duck-billed dinosaurs

New findings are adding a wrinkle to researchers’ understanding of how duck-billed dinosaurs conquered the Cretaceous world.

Physics

Neutrinos offer a new view of the Milky Way

Physicists turned to AI to help map out the newfound origins of ghostly neutrino particles coming from deep in the Milky Way.

Plants

Soil microbes that survived tough climates can help young trees do the same

Trees grown in soil with microbes that have survived drought and high or low temperatures have a better shot at survival when facing the same conditions.

Life

Here are 5 record-breaking science discoveries from 2022

The earliest surgery, fastest supercomputer and biggest single-celled bacteria were some of this year’s top science superlatives.

Climate

Ancient penguin bones reveal unprecedented shrinkage in key Antarctic glaciers

Thwaites and Pine Island glaciers are losing ice faster than any other time in the last 5,500 years. That history is written in bones and shells.

Planetary Science

Machine learning points to prime places in Antarctica to find meteorites

Using data on how ice moves across Antarctica, researchers identified more than 600 spots where space rocks may gather on the southern continent.

Climate

Antarctica’s Thwaites Glacier ice shelf could collapse within five years

The loss of Thwaites’ buttressing ice shelf could hasten the demise of the “Doomsday Glacier” and raise the risk of dramatic sea level rise.

Paleontology

Mammoths may have gone extinct much earlier than DNA suggests

Ancient DNA in sediments may be leading paleontologists astray in attempts to figure out when woolly mammoths and woolly rhinos died out, a new study argues.

Planetary Science

Asteroid impacts might have created some of Mars’ sand

Roughly a quarter of the Red Planet’s sand is spherical bits of glass forged in violent impacts, new observations reveal.

Oceans

Some deep-sea octopuses aren’t the long-haul moms scientists thought they were

Off California’s coast, some octopuses lay eggs in the warmer water of geothermal springs in the “Octopus Garden,” speeding up their development.
