Phys.org / Is dark energy actually evolving?
Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing the expansion of the ...
Medical Xpress / Closing in on a universal vaccine: Nasal spray protects mice from respiratory viruses, bacteria and allergens
In the realm of medical advancements, a universal vaccine that can protect against any pathogen has long been a Holy Grail—and about as elusive as a mythological vessel. But Stanford Medicine researchers and collaborators ...
Tech Xplore / Laser-etched glass can store data for 10,000 years, Microsoft says
Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.
Phys.org / Rocket re-entry pollution measured in atmosphere for first time
When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacuglar fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing toward ...
Phys.org / Hubble identifies a near-invisible galaxy that may be 99% dark matter
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter and containing ...
Phys.org / Not all humans are 'super-scary' to wildlife, animal behavior study suggests
Humans have climbed to the top of the food chain by skillfully hunting, trapping, and fishing for other animals at scales that far exceed other predators, altering how the animals behave and earning the tag of a "super-predator." ...
Tech Xplore / AI and kindness: Are we morally obligated to be kind to Grok?
Would you ever kick your Roomba? Or leave a scathing review of the robot at a Thai restaurant who delivered your green curry? What about sending a mean message to ChatGPT?
Phys.org / Cleaner fish show intelligence typical of mammals
Researchers at Osaka Metropolitan University in Japan have discovered a previously undiscovered behavior in cleaner wrasse (Labroides dimidiatus). When presented with a mirror, the tiny fish not only recognized themselves, ...
Phys.org / Could a recently reported high-energy neutrino event be explained by an exploding primordial black hole?
The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep Mediterranean Sea, with the aim of detecting high-energy neutrino events. These are rare and fleeting ...
Phys.org / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Phys.org / Quantum entanglement pushes optical clocks to new precision
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze ...
Medical Xpress / DeepRare AI outperforms doctors on rare disease diagnosis in head-to-head test
Rare diseases are complex medical disorders that are notoriously difficult to diagnose because many present with a wide variety of symptoms that can overlap with more common illnesses. Currently, around 300 million people ...
