Phys.org / Gravity follows Newton and Einstein's rules, even at cosmic scales
Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that guides the shape and evolution ...
Phys.org / DESI completes planned 3D map of the universe and continues exploring
The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone ...
Phys.org / Atlantic current shows two-decade decline across four deep-ocean monitoring sites
A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on ...
Tech Xplore / Fusion power may never be cost-competitive with renewables, study warns
Fusion power plants are sites at which electricity could be generated via a process known as nuclear fusion, which entails the merging of two atomic nuclei into a single heavier nucleus. This process is known to generate ...
Phys.org / Torsion balances set strongest direct limits yet on ultralight dark matter
Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...
Phys.org / Could dark matter be made of black holes from a different universe?
New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.
Phys.org / People with dark personality traits are naturally inclined towards leadership roles, finds new study
Can you tell if you're working with a narcissist or a psychopath? A new study suggests that people's job choices may offer some clues, especially in fields built on leadership and persuasion such as business, politics, and ...
Phys.org / This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models
Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...
Phys.org / Weighing in on the mystery of the gravitational constant
The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay inside. For the past 10 ...
Phys.org / Navigating the past with ancient stone compass needles
Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock ...
Phys.org / The moon might be more prone to fires
Engineers love a good practical challenge, especially when it comes to spaceflight. But there's one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. ...
Tech Xplore / Engineered wood provides solar power even after the sun goes down
While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of ...
