Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really th...
Quantum heat circuits learn electronics' oldest trick: Sharing a power supply
Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and ref...
As charitable food aid expands, new study raises questions for food security policy
As food insecurity persists across high-income countries, charitable organizations and food banks are playing an increasingly important role in helping househol...
Distant time crystals oscillate in unison, paving the way for spin networks
In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours. In...
When meat doesn't matter: Female Guinea baboons do not prefer males who are better at acquiring or sharing meat
Meat is a rare and highly prized resource for wild Guinea baboons (Papio papio). Yet, contrary to long-standing assumptions based on human hunter–gatherer socie...
The impact of recent super El Niños on sea level rise
El Niños and La Niñas are the third-most dominant influences on Earth's climate, after the sun and the greenhouse effect. But they haven't been easy to decipher...
Climate change could mean four extra hours of extreme heat on hot days
Hot days could gain more than four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a modeling stud...
Europe braces for another summer heat wave
Much of Europe is bracing for another scorching heat wave following periods of record drought that have driven rivers to historic lows, ignited historic forest...
Arctic fossil abandoned in 1948 proves to be record-size Triassic hunter
Nearly 80 years ago, a British expedition discovered the battered remains of a giant fossil on the peak of an Arctic island. Unable to take it with them, they s...
The lasting impacts of West Nile virus on Pennsylvania bird populations
A new study out of the University of Pennsylvania School of Veterinary Medicine suggests that West Nile virus (WNV) has had impacts on one in five Pennsylvania...
Self-healing composite retains 92% sensing response after 10,000 strain cycles
