A research team led by the University of Bern has developed a novel learning mechanism for neural networks modeled after the human brain. “Spike-based Alignment Learning” uses random fluctuations in the activity of artificial neurons to reveal asymmetric connections, allowing synapses that are far apart to autonomously align with oneContinuar Leyendo
This starry view of the nearby star-forming region IC 348 is one of the largest images from the NASA/ESA/CSA James Webb Space Telescope released to the public so far. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive than the smallest stars. The researchers discovered brownContinuar Leyendo
Comment le changement climatique modifie-t-il les processus à l’œuvre dans l’océan Arctique ? Pourquoi des masses de glace se détachent-elles des glaciers du Groenland pour tomber dans la mer ? Deux jeunes scientifiques reçoivent le Prix de Quervain pour leurs recherches sur ces questions. Ce prix récompense cette année deuxContinuar Leyendo
Quantum particles turn into a spread-out ‘wisp of fog’ when they cross a mirror-like boundary. Cambrigde, Sept 12, 2026.- A quantum particle that crosses a ‘duality defect’ – a boundary between order and disorder – is never reflected. It always passes through, but it comes out changed: not a particle,Continuar Leyendo
New York, Sept 10, 2026.- Stopping tumor growth is only half the battle. Rather than kill tumor cells, many cancer therapies can only push them into cellular senescence, a state in which cells stop dividing but do not die. These “undead” cells will continue to release signals that reshape theContinuar Leyendo
The ancestor to a ‘cluster-of-clusters’ of galaxies has a mass 5000 times that of the Milky Way and lies in one of the densest regions of the cosmic web ever observed. Tucson, Sept 08, 2026.- An international team of astronomers has discovered the most distant progenitor to a galaxy superclusterContinuar Leyendo
Project Hōkūlani interns researched and named this new Gemini North image featuring the stunning pair of interacting galaxies known as NGC 7253 Tucson, Sept 02, 2026.-Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to this image of NGC 7253 — a pair of spiral galaxiesContinuar Leyendo
A 10-year study shows that expectations of one’s own ageing are a ‘self-fulfilling prophecy’ What we expect from our own ageing is not merely a notion. In two recent studies, an international research team led by psychologist Christina Ristl from the University of Vienna has shown that our expectations regardingContinuar Leyendo
Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from the NASA/ESA Hubble Space Telescope show definitive evidence of a dwarf galaxy merging with the young Milky Way galaxy in the earliest phases of its evolution. This finding extendsContinuar Leyendo
Long-term study across 53 European mountain summits shows that the response of alpine vegetation to climate change depends heavily on local conditions Decades of climate change have not left Europe’s mountain vegetation unscathed. However, the changes observed do not always match expectations. As a new international study by a researchContinuar Leyendo
