When we recall something familiar or explore a new situation, the brain does not always use the same communication routes. An international study led by Claudio Mirasso at the Institute for Cross-Disciplinary Physics and Complex Systems (IFISC), a joint center of the Spanish National Research Council (CSIC) and the University of the Balearic Islands (UIB),…

Stem cell transplantation can reverse stroke damage, researchers at the University of Zurich report. Its beneficial effects include regeneration of neurons and restoration of motor functions, marking a milestone in the treatment of brain disorders. One in four adults suffer a stroke in their lifetime, leaving around half of them with residual damage such as…

A study examining the effects of higher temperatures on soil shows that warming alone does not increase levels of carbon dioxide emitted from the soil. Instead, higher temperatures combined with more added carbon – and more nutrients like nitrogen and phosphorus – led to higher carbon dioxide levels released from the soil. The findings provide…

Scientists at NYU Abu Dhabi (NYUAD) have developed an artificial intelligence (AI) model that can forecast solar wind speeds up to four days in advance, significantly more accurately than current methods. The study is published in The Astrophysical Journal Supplement Series. Solar wind is a continuous stream of charged particles released by the Sun. When…

When Rutgers theoretical astrophysicist Charles Keeton first saw an unusual picture shared by his colleague, he was intrigued. “Have you ever seen an Einstein Cross with an image in the middle?” his colleague Andrew Baker asked, referring to a rarely seen cosmic configuration. Keeton hadn’t. The implications were enormous. “I said, well, that’s not supposed…

New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought and provided an unexpected solution to a 50-year-old mystery about our nearest star. Solar flares are sudden and huge releases of energy in the Sun’s outer atmosphere that heat parts of it to…

An asteroid has fragmented in an unexpected way Wikimedia/CC-BY-SA-4.0 An asteroid exploded over France two years ago in a rare single explosive event, raising concerns about future planetary defence from certain types of these rocky bodies. On 13 February 2023, a small asteroid called 2023 CX1 entered Earth’s atmosphere and streaked across the skies of…
