Ancient giant kangaroos could hop to it when they needed to, hindlimb study suggests
Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, accordi...
NASA's Artemis II mission to fly legacy keepsakes with astronaut crew
As America approaches its 250th anniversary of declaring independence, NASA's Artemis II mission will carry a host of mementos that reflect the nation's long tr...
Study challenges long-held theory that language is built on grammar trees
Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-s...
DNA nanodevices reveal acidic nanolayer on lysosome surfaces in live cells
Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is known to regulate cytosolic-side fu...
Battery-free nano-sensors could pave the way for next-generation wearables
Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to...
Rethinking where life could exist beyond Earth
Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold f...
3D-printed surfaces help atoms play ball to improve quantum sensors
Scientists have created 3D printed surfaces featuring intricate textures that can be used to bounce unwanted gas particles away from quantum sensors, allowing u...
Scientists solve 66 million-year-old mystery of how Earth's greenhouse age ended
A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Th...
Stress-reduction molecule has potential to treat aging and metabolic disorders
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and...
Chimpanzees are better at solving resource dilemmas in larger, more tolerant groups
Despite being one of the most cooperative species on the planet, humans routinely fail to manage shared resources sustainably. We overfish from the oceans, burn...
Scientists may have discovered a new extinct form of life
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters....
Scientists illuminate ancient plant-fungus partnership at molecular level
For 450 million years, plants and soil fungi have been trading partners. The fungi weave through plant roots, delivering phosphorus and other soil minerals in e...
