Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a two-step immune reaction that floods the body with inflammatory signals, drawing
Humans and dogs have been living together side by side for thousands of years, so you would think we know everything about our four-legged friends by now. But we may not understand them as well as we think we do.
UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects. By identifying two key enzymes that shape and twist molecules into their final form, the team solved a puzzle that had stumped scientists for years.
Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not settle into an ordered pattern and continue to fluctuate, even at extremely low temperatures. This state is characterized by high entanglement, a quantum
An international team of scientists, including the University of Wollongong (UOW), has found compelling evidence that a changing climate played a role in the extinction of the early human species Homo floresiensis, also known as "hobbits." Their research, published in
Neutrinos may be nearly invisible, but they play a starring role in the Universe. Long-standing anomalies had hinted at a mysterious fourth “sterile” neutrino, potentially rewriting the laws of physics. Using exquisitely precise measurements of tritium decay, the KATRIN
Sleep is often the first thing that many people associate with rest, but humans also require restorative downtime when awake
Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone emergency fix that helps them survive. Some cancer cells rely heavily on this
Photis Gaitanos' rough fingers adroitly untangle the venomous spikes of a lionfish from a net, throwing the exotic-looking creature into an ice-filled rubber bin along with other fish from the day's catch.
A newly identified region on Mars may hold the key to future human landings. Researchers found evidence of water ice less than a meter beneath the surface, close enough to be harvested for water, oxygen, and fuel. The location strikes a rare balance between sunlight and cold,
New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of years. This unexpected shift suggests the structure around supermassive black holes may evolve with time, challenging a decades-old assumption.

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the sublattices are linked by simple inversion or translation, resulting in
Distinctive in taste and famously divisive, durian is not everyone's choice of fruit. This was certainly the case for some Chinese explorers when they first encountered it during the Ming Dynasty's early maritime voyages.
Obituaries preserve what families most want remembered about the people they cherish most. Across time, they also reveal the values each era chose to honor.
An elusive wild cat long feared extinct in Thailand has been rediscovered three decades after the last recorded sighting, conservation authorities and an NGO said Friday.
