From Jurassic Park to dreams of AI doom, pop culture shapes science more than we like to admit
The relationship between science and pop culture often looks like a one-way street: scientific discoveries inspire films, television and novels, particularly in science fiction. But the relationship really goes both ways, and extends beyond sci-fi.
How Artemis II's Earthset photo compares with the iconic Earthrise image from 1968
As NASA's Artemis II mission completed its lunar flyby, the astronauts sent back a stunning image of the colorful Earth setting behind the moon. This breathtaking photo, called Earthset, draws inevitable comparisons with the original Earthrise photo from the Apollo 8 flight in
Scientists build arsenic-lined crystal pore framework to boost rhodium catalyst performance
Rhodium is one of the most powerful catalytic metals known to chemistry. Small amounts of it can drive reactions that produce millions of tons of useful chemicals every year. But getting rhodium to work well—quickly, selectively, and without degrading—depends heavily on the
How does spider venom damage human cells? Researchers uncover the killer mechanism of recluse spider toxin
Spiders are among Earth's most resourceful predators, nabbing prey by any means necessary. Orb weavers spin webs for capture. Wolf spiders ambush on the ground at night. Almost all spiders use venom when they hunt.
Embryo fossil found in South Africa is world's oldest proof that mammal ancestors laid eggs
Between 280 and 200 million years ago, a group of animals evolved which would eventually give rise to mammals, including humans: the therapsids. They were first described more than 150 years ago, based on fossils from South Africa. Since then, many more fossils have been
Advanced mirror technology now powers a breakthrough X-ray telescope
Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology with space astronomy. To test its performance, they built a first-of-its-kind
JAXA plans to bring back pristine early solar system samples from a comet
Japan's space agency, JAXA, has been knocking it out of the park with small-body exploration missions for decades. They had historic successes with both Hayabusa and Hayabusa2, and they are going to visit the Martian moons soon with the Martian Moons eXploration (MMX) mission.
Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau
A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the finds were a genus of giant tortoise (Hesperotestudo) and
Scientists spot a solar flare with surprising spectral behavior
On August 19, 2022, solar astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and
