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 / 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 / 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 / Gravitational wave signal tests Einstein's theory of general relativity
For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers an opportunity to test ...
Medical Xpress / Washington state measles outbreak grows
Three more measles cases have been confirmed in Snohomish County after an outbreak began two weeks ago, public health officials said on Jan. 28. Earlier in January, three children in Snohomish County tested positive for measles ...
Phys.org / Argentina declares emergency over Patagonia wildfires
Argentina's government on Thursday declared an emergency in Patagonia, where wildfires have ripped through vast tracts of forest since the start of the Southern Hemisphere summer.
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 / 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 ...
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 / 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 / To reduce CO₂ emissions, policy on carbon pricing, taxation and investment in renewable energy is key
A new study evaluating climate policies in 40 countries over a 32-year period finds that carbon pricing and taxation—combined with investments in renewable energy and research—are among the most effective tools governments ...
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.
