Phys.org / Most normal matter in the universe isn't found in planets, stars or galaxies: An astronomer explains
If you look across space with a telescope, you'll see countless galaxies, most of which host large central black holes, billions of stars and their attendant planets. The universe teems with huge, spectacular objects, and ...
Phys.org / Probing the existence of a fifth force via neutron star cooling
Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into space.
Medical Xpress / Chronic cannabis use, vomiting and compulsive bathing—symptoms of a hidden syndrome
Researchers at the Jane Addams College of Social Work at the University of Illinois Chicago have found that cannabinoid hyperemesis syndrome, a vomiting condition tied to chronic cannabis use, rose sharply in US emergency ...
Phys.org / Human hair grows through 'pulling' not pushing, study shows
Scientists have found that human hair growth does not grow by being pushed out of the root; it's actually pulled upward by a force associated with a hidden network of moving cells. The findings challenge decades of textbook ...
Phys.org / Close-up images show how stars explode in real time
Astronomers have captured images of two stellar explosions—known as novae—within days of their eruption and in unprecedented detail. The breakthrough provides direct evidence that these explosions are more complex than ...
Phys.org / New deep-sea species discovered during mining test
There is high global demand for critical metals, and many countries want to try extracting these sought-after metals from the seabed. An international study, which has discovered large numbers of new species at a depth of ...
Phys.org / Alaknanda: JWST discovers massive grand-design spiral galaxy from the universe's infancy
A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy just ...
Phys.org / Time-delay cosmography may enable a speed camera for the universe
There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and resolving this could reveal new physics. Astronomers constantly seek new ways to measure this expansion ...
Phys.org / Climate action saves lives. So why do climate models ignore well-being?
Climate change is already shaping our well-being. It affects mental health, spreads infectious diseases, disrupts work, damages food supplies and forces families to leave their homes because of conflict, hunger or flooding.
Phys.org / Alkaline-loving microbes could help safeguard nuclear waste buried deep underground for thousands of years
Billions of alkaline-loving microbes could offer a new way to protect nuclear waste buried deep underground. This approach overcomes the limitations of current cement barriers, which can crack or break down over time.
Phys.org / Cats adjust their communication strategy by meowing more when greeting men
As many cat owners will testify, their pets are often mysterious creatures, independent, cunning and sometimes aloof. And now it appears that when it comes to communication, they might be playing favorites. A new study published ...
Phys.org / The case for an antimatter Manhattan project
Chemical rockets have taken us to the moon and back, but traveling to the stars demands something more powerful. Space X's Starship can lift extraordinary masses to orbit and send payloads throughout the solar system using ...
