Galaxies rotate faster than the matter we can see should allow. Evidence for an unseen, gravitating substance began to build in the 1930s with Fritz Zwicky’s studies of galaxy clusters, and strengthened in the 1970s as Vera Rubin measured how stars orbit within spiral galaxies. Nearly a century later, dark matter is still known almost […]

Probiotics are part of a rapidly expanding field of research. They are live microorganisms that, when administered in adequate amounts, may confer health benefits[1]. Among the most extensively studied probiotics, some species of Lactobacillus and Bifidobacterium have been associated with the maintenance of gut microbiota balance and with several physiological functions[2]. Producing these microorganisms usually […]
Author: Deven Desai, Professor of Business Law and Ethics; Associate Director for Law, Policy, and Ethics at the Machine Learning Center, Georgia Institute of Technology AI agents don’t go rogue. That’s something only humans do. Nevertheless, a New York Times article – representative of much news coverage of AI – described an OpenAI hacking as […]
Scientists have developed remarkably long, precisely patterned molecular threads that could open new possibilities for designing advanced materials. The scientists also discovered these threads — called supramolecular polymers — can dramatically enhance brain cell activity. Built from self-assembling molecules, the longest threads reach dimensions greater than the diameter of a cell. By molecular standards, they […]
In 1911, Heike Kamerlingh Onnes cooled mercury to a few degrees above absolute zero and watched its electrical resistance vanish. Lead soon joined the list of superconductors, losing its resistance below about 7.2 kelvin. A full explanation arrived in 1957: electrons bind into Cooper pairs that move together as one collective state below a critical […]
Author: Tania Ahmed, Honorary Postdoctoral Associate, Macquarie University Astronomers have catalogued billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where these galaxies sit and trace how the universe changes over time. The universe also contains objects that are too faint, too far […]
When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) shows that waves can behave very differently when they travel through a special class of materials. The […]
26 April 2026 will always be remembered as the day an apparently impossible barrier was finally broken. At the London Marathon, Kenya’s Sabastian Sawe and Ethiopia’s Yomif Kejelcha became the first men to officially run the 42.195 km distance in under two hours, finishing in 1:59:30 and 1:59:41 respectively. Reaching this landmark was not the […]
One of the most powerful ways to study the Universe is to map where galaxies are located. Galaxies are not scattered randomly through space; they gather into groups, clusters, filaments and other structures that trace the underlying distribution of dark matter. The pattern of this cosmic web carries information about the basic ingredients and history […]
Author: Aysha Asif Riaz, Research Fellow in Roadmapping Neuromorphic Computing Hardware, Department of Electronic and Electrical Engineering, UCL Right now, your brain is recognising the shapes of these letters, analysing their meaning, and holding a stream of thought together – all on about 20 watts of power. That’s roughly what it takes to run a […]
