Long-term exposure to low levels of a common agricultural pesticide can accelerate physiological aging and shorten lifespan in fish—a finding from new research led by University of Notre Dame biologist Jason Rohr with potentially far-reaching implications for environmental regulations and human health.
A new study led by researchers at the University of Oxford has shown that the shape and orientation of coastlines significantly influenced extinction patterns for animals living in the shallow oceans during the last 540 million years. In particular, animals living on convoluted or east-west oriented coastlines (such as those found in the Mediterranean and Gulf of Mexico today) were more likely to go extinct than those living on north-south oriented coastlines.
By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise to devastating major earthquakes.
Many women have experienced severe distress as Grok, the AI chatbot on social media site X, removed clothing from their images to show them in bikinis, in sexual positions or covered in blood and bruises. Grok, like other AI tools, has also reportedly been used to generate child sexual abuse material.
The woolly rhino, Coelodonta antiquitatis, would have been an impressive sight to the ancient people who painted images of them on cave walls and carved figurines of them out of bone, antler, ivory and wood.
In Tana Toraja, a mountainous region of Sulawesi, Indonesia, villagers pour massive resources into funeral rituals: lavish feasts, ornate effigies and prized water buffaloes for sacrifice.
Labor market returns for female graduates have been historically overestimated using tax data, as much of the documented graduate pay premium is the result of female graduates working longer hours, not higher hourly wages, a UCL-led study finds.
After more than 10 years in orbit, the first Copernicus Sentinel-2 satellite, Sentinel-2A, is still finding new ways to contribute to Earth observation. With its younger siblings, Sentinel-2B and Sentinel-2C, now leading the mission's core task of delivering high-resolution, 'camera-like' images of Earth's surface, the European Space Agency is pushing Sentinel-2A beyond its original remit.
An international team of researchers, with the involvement of the UAB, has conducted a study that explains the evolutionary origins of the Dehnel phenomenon, a unique seasonal adaptation in small mammals that involves the ability to reduce and recover brain volume and function. The study is published in Molecular Biology and Evolution.
Quantum computers could rapidly solve complex problems that would take the most powerful classical supercomputers decades to unravel. But they'll need to be large and stable enough to efficiently perform operations. To meet this challenge, researchers at MIT and elsewhere are developing quantum computers based on ultra-compact photonic chips. These chip-based systems offer a scalable alternative to some existing quantum computers, which rely on bulky optical equipment.
