Phys.org / High-resolution map shows dark matter's gravity pulled normal matter into galaxies
Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets.
Phys.org / Is time a fundamental part of reality? A quiet revolution in physics suggests not
Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and we die, in exactly that ...
Phys.org / Webb pushes boundaries of observable universe closer to Big Bang
The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed ...
Phys.org / For injured sea turtles like 'Porkchop,' Southern California's Aquarium of the Pacific has doubled its care space
A hunk of romaine was easy pickings for Porkchop and her three flippers. On a rainy day last week, the green sea turtle pumped her limbs and stretched her beak up to chomp a lettuce leaf floating on the surface of a tank ...
Phys.org / A new method to search for ultralight dark matter with advanced optical cavities
Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect evidence of its existence, ...
Phys.org / Fast-growing trees are taking over the forests of the future and putting biodiversity, climate resilience under pressure
Trees play a central role in life on Earth. They store CO₂, provide habitats for animals, fungi, and insects, stabilize soils, regulate water cycles, and supply resources that humans rely on—from timber and food to recreation ...
Phys.org / The magnetic 'birdsong' of the smallest planet
BepiColombo is slowly uncovering more and more fun facts about Mercury as it continues its preliminary mission. One of the more interesting things found so far is a magnetic "chorus" that appears similar to a phenomenon found ...
Medical Xpress / The brain's protein cleanup process may play a role in dementia
Microglia are the brain's immune cells that clean out debris, such as damaged proteins and old cell parts, to keep the organ healthy. But the very properties that make these cells so useful might also be a driving factor ...
Phys.org / 2D discrete time crystals realized on a quantum computer for the first time
Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...
Phys.org / Milky Way is embedded in a 'large-scale sheet' of dark matter, which explains motions of nearby galaxies
Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local Group of galaxies (which ...
Phys.org / World not ready for rise in extreme heat, scientists say
Nearly 3.8 billion people could face extreme heat by 2050 and while tropical countries will bear the brunt cooler regions will also need to adapt, scientists said Monday.
Phys.org / AI enables a who's who of brown bears in Alaska
A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season. ...
