Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have made a major discovery in how human cells produce energy. Their study, published in The EMBO Journalreveals the detailed mechanisms […]
A Mexican delegation has retrieved 84 Mesoamerican axes. Credit: Amélie Philibert, Université de MontréAl A Mexican delegation is coming to retrieve 84 Mesoamerican axes currently in transit at UdeM, underscoring the need to raise public awareness of the looting of archaeological artifacts. With its rich pre-Columbian history and huge trove of cultural treasures, Mexico has […]

Credit: Radiocarbon (2024). DOI: 10.1017/RDC.2024.99 New research by Flinders University researchers, conducted in partnership with the River Murray and Mallee Aboriginal Corporation (RMMAC), has documented ancient […]

Scientists surveyed reefs at 100 sites around the Palm Islands, Magnetic Island, Whitsunday Islands, and Keppel Islands over a 14 year […]
The puzzling, fascinating surface of Jupiter’s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA’s Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that shows the largest portion of the moon’s surface at the highest resolution. Credit: NASA/JPL-Caltech/SETI Institute. Scientists have […]
Credit: Unsplash/CC0 Public Domain Why is human culture—the shared body of knowledge passed down across generations—so much more powerful than animal cultures? “What’s special about our species?” is a question scientists have wrestled with for centuries, and now a scientist at Arizona State University has a new hypothesis that could change the way we perceive […]
In an Electron-Ion Collider (EIC) collision, interactions between a virtual photon emitted by the colliding electron can reveal the arrangement of quarks and gluons within a hadron—in this case a proton that is part of a larger nucleus.

Primordial black holes (PBHs), which are thought to have formed right after the Big Bang, may be heating up and exploding throughout the universe. These black hole explosions, powered by Hawking radiation — a quantum process where black holes generate particles from the vacuum due to their intense gravitational fields — could be detected by […]

Credit: Manon Sas/Utrecht University Heat, dry spells and flooding—the whole of nature is under stress, and potatoes are no exception. As a food staple, there is particular interest in getting potatoes fit for the new climate reality. As part of the EU’s four-year ADAPT project, […]
