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 ...
Dialog / Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles
Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...
Phys.org / What do sushi, climbing and smoking have in common? How we talk about risk
Next week, Sara Perlstein will defend her Ph.D. on risk talk: the everyday conversations we have about risks with people close to us. From eating sushi to climbing or smoking, these informal talks shape how we deal with danger ...
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 / 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 / Self-interacting dark matter may solve three cosmic puzzles
A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments. Published in Physical Review Letters, the study proposes ...
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.
Medical Xpress / Loneliness highest among older Australians without partners or children
As Australia's population ages and loneliness becomes a growing public health concern, new research from Monash University has found that older Australians without close family ties face significantly higher rates of loneliness. ...
Phys.org / Scientists capture superconductivity's 'dancing pairs' for first time, revealing missing pieces in a decades-old theory
For the first time, scientists have directly imaged the quantum process underlying superconductivity, a phenomenon in which paired electrons cause electric current to flow without resistance at sufficiently low temperatures. ...
Phys.org / As Artemis II is celebrated, the world faces hard questions about US leadership in space
The successful Artemis II trip around the moon was a historic achievement—the first crewed lunar fly-by in more than 50 years, and the greatest distance yet traveled by humans from our "pale blue dot."
Phys.org / Unearthed mega-structure hints at communal rule in Romania 6,000 years ago
Archaeologists working at the ancient settlement of Stăuceni-"Holm" in northeastern Romania have uncovered a mega-structure measuring 350 square meters dating back about 6,000 years. This is one of the few examples of a massive ...
Phys.org / Ancient Maya droughts may have been fueled by Earth's own climate swings
Dramatic droughts linked to the decline of the Classic Maya civilization approximately 800 to 1000 CE may not have required any external trigger, according to a new climate modeling study. Instead, they could have emerged ...
