In 2014, members of a local museum found fragments of an ancient fossil dating to the end of the Pliocene or early Pleistocene epoch in a seaside cliff on the Argentine pampas. They belonged to a large predator, but the only group they fit, saber-toothed marsupial relatives,
Almost every ceremonial object or ornament of the medieval papal monarchy has disappeared or lost its original purpose. Yet one survives: the golden rose. On Sept. 26, 2026, during Pope Leo XIV's visit to France, he traveled to Lourdes, home to one of the world's most famous
The 2026 U.S. midterm campaigns are the first in which AI-generated political ads are regularly appearing on people's televisions and social media feeds. We are researchers who have been studying political advertising through the Wesleyan Media Project since 2010. This election
A new study of shark anatomy suggests the shape of their inner ears is far more variable than expected, and this variation could have more to do with their evolutionary history than where they live or what they eat.
If the goal was to silence rapper Macklemore by preventing him from touring with singer Ed Sheeran, it clearly backfired. Macklemore delivered a monolog in support of Palestinians in Gaza and the West Bank and performed his pro-Palestinian protest song "Hind's Hall" during a
When a prairie river carries more water in one year than another, the obvious place to look for an explanation is the sky. A year with more snow and rain should have more water in rivers. That was also how I initially thought about year-to-year changes in river flow. But while

Deep space travel comes with a huge potential downside—radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. But what exactly does that mean, and is there any way to handle it other than sticking more and more protective
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's not the end of the weirdness. Their formation could have
The country’s space program is new and ambitious, having already sent a mission into Mars orbit
One of the hardest challenges in wildlife conservation arises when the habitat of a species in need of protection overlaps with land used by humans. Wolves and bears can kill livestock, elephants can damage homes and other property and wild boar can damage crops.
Heat shields are one of the most important parts of any spacecraft that intends to enter an atmosphere. And the material they are made of is critical. Improving them has been a challenge, though, as researchers typically only get "before" and "after" pictures of a heat shield's
As they fly about their usual business of pollinating flowers, bumblebees could help protect fruit trees from disease by carrying a natural treatment directly to where it is needed.
Water does not flow only through rivers on the ground. Vast quantities of water also move through the atmosphere, carried by winds from oceans and land before eventually falling as precipitation hundreds or even thousands of kilometers away. These persistent pathways of
