Spanish researchers have demonstrated a scalable manufacturing process for carbon nanotube (CNT) fibers with electrical conductivity comparable to that of copper and aluminum. The result, published in Science, is a breakthrough for the future of electrification in aerospace, electric vehicles (EVs), drones and related applications, which require lightweight and high-strength electrical wiring.

CNTs have long been considered as ideal building blocks for electrical conductors, owing to their unique combination of low densi...

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense Xray flares at regular intervals that have puzzled scientists, a study said Friday.

Astronomers previously had little reason to pay any attention to galaxy SDSS1335+0728, which is 300 million light years from Earth.

But in 2019, the galaxy suddenly started shining with a brightness that turned some telescopes its way.

Then in February last year, Chilean astronomers started noticing regular bursts of X-rays coming from the galaxy.

This was a sign that the galaxy’s sleeping black hole was waking from its slumber, ...

Scientists at the Terasaki Institute for Biomedical Innovation, in collaboration with the University of Maryland School of Pharmacy, have developed a new nanoparticle therapy that tackles obesity through two complementary mechanisms: converting energy-storing white fat into calorie-burning beige fat while simultaneously reducing obesity-related inflammation.

Their findings, published in the Journal of Controlled Release, are detailed in an article titled “Apigenin-loaded nanoparticles for obesity intervention through immunomodulation and adipocyte browning...

Computer chips that combine the use of light and electricity are shown to increase computational performance, while reducing energy consumption, compared with conventional electronic chips. The photonic computing chips, described in two papers in Nature this week, might address the growing computing demands driven by advancing artificial intelligence technology.

The growth in the complexity of artificial intelligence and deep learning models is pushing conventional electronic computing to its limits and has ever-increasing energy demands. Photonic computing, which uses photons rather than electrons, presents a potential solution to these challenges.

Multiplication and accumulation—central computational operations for artificial intelligence—can be performed faster and more effic...
