A nearby active galaxy called VV 340a offers a dramatic look at how a supermassive black hole can reshape its entire host. Astronomers observed a relatively weak but restless jet blasting outward from the galaxy's core, wobbling like a spinning top . ...

NASA's Artemis II rocket has reached its launch pad after a painstaking overnight crawl across Kennedy Space Center. Engineers are now preparing for crucial fueling and countdown tests ahead of the first crewed Artemis mission. The mission will send ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic collapse inside dark matter halos, heating and ...

As global energy demand surges--driven by AI-hungry data centers, advanced manufacturing, and electrified transportation--researchers at the National Renewable Energy Laboratory have unveiled a breakthrough that could help squeeze far more power from ...

Solid-state batteries could store more energy and charge faster than today's batteries, but they tend to crack and fail over time. Stanford researchers found that a nanoscale silver treatment can greatly strengthen the battery's ceramic core. The ...

A huge bar of iron has been discovered lurking inside the iconic Ring Nebula. The structure is enormous, spanning hundreds of times the size of Pluto's orbit and containing a Mars-sized amount of iron. It was detected using a new instrument that ...

When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both viruses and bacteria evolved differently over time. .. ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip--and it could transform future electronics. Using a new kind of "phonon laser," the team can produce ultra-fast surface waves that already play ...

Researchers have turned artificial intelligence into a powerful new lens for understanding why cancer survival rates differ so dramatically around the world. By analyzing cancer data and health system information from 185 countries, the AI model ...

Humans pay enormous attention to lips during conversation, and robots have struggled badly to keep up. A new robot developed at Columbia Engineering learned realistic lip movements by watching its own reflection and studying human videos online. This ...
