Available for over a year Astronomers have new evidence, which could change what we understand about the expansion of the universe. Carlos Frenk, Ogden Professor of Fundamental Physics at Durham University gives us his take on whether the dark energy pushing our universe apart is getting weaker. With the Turing Prize, the Nobel Prize and…
Scientists are working to make renewable technologies more efficient by studying ultra-thin materials known as two-dimensional (2D) materials. These materials could open new pathways for producing essential chemicals like ammonia, a key ingredient in fertilizer, through cleaner and more sustainable methods. Among these materials, a family called MXenes stands out. MXenes are low-dimensional compounds capable…
Antarctica faces the possibility of sudden and potentially irreversible changes to its ice, oceans, and ecosystems. Scientists warn that without a sharp global reduction in carbon emissions, these transformations could have serious effects not only for the continent but also for Australia and the rest of the planet. The warning comes from new research published…
An international team led by ICREA researcher Mark Gieles from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) has created a new model that sheds light on how extremely massive stars (EMS), with more than 1,000 times the mass of the Sun, shaped…
For many years, scientists have believed that dark matter and dark energy make up most of the cosmos. But new research challenges that view, suggesting these mysterious components might not exist at all. Instead, the effects we attribute to them could arise naturally if the fundamental forces of the universe slowly weaken as it grows…

A new study from astronomers at UCL (University College London) and the University of Warwick suggests that aging stars may be destroying the giant planets orbiting closest to them. When stars like the Sun exhaust their hydrogen fuel, they begin to cool and expand, transforming into red giants. For our Sun, this dramatic phase is…
The universe may not be speeding up after all. According to a new study, its expansion could actually be slowing down, challenging one of modern cosmology’s most fundamental ideas. The findings, published November 6 in Monthly Notices of the Royal Astronomical Society, question the long-accepted belief that a mysterious force known as “dark energy” is…
Coffee plants can be propagated by grafting a shoot onto the rootstock of another plant sirichai_asawalapsakul/Getty Images The ancient trick of grafting one plant onto another could find a very modern use – enabling gene editing of plants that are very difficult or impossible to edit by other means. “It is still at the beginning…
Scientists at Weill Cornell Medicine have identified a surprising culprit that may contribute to dementia: free radicals generated in a particular region of brain support cells known as astrocytes. The study, published Nov. 4 in Nature Metabolism, found that blocking this specific site reduced inflammation and protected neurons. The results point toward a promising new…
