Phys.org / Unexpected discovery on Saturn's moon challenges view on chemistry before life emerged
Researchers at Chalmers University of Technology in Sweden and the US space agency NASA have made an unexpected discovery that challenges one of the basic rules of chemistry and provides new knowledge about Saturn's enigmatic ...

Phys.org / One of world's oldest dinosaurs discovered in Argentina
Argentinian scientists have found fossilized bones of one of the world's oldest dinosaur species in the Andes Mountains, the CONICET research agency announced on Wednesday.

Phys.org / Coral skeletons left by a medieval tsunami whisper a warning for Caribbean region
Sometime between 1381 and 1391, an earthquake exceeding magnitude 8.0 rocked the northeastern Caribbean and sent a tsunami barreling toward the island of Anegada.

Phys.org / Streamlined method to directly generate photons in optical fiber could secure future quantum internet
With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication systems. To counter this, ...

Phys.org / Stinkbug's 'ears on legs' are really symbiotic organs that nurture fungi for guarding eggs against enemies, study finds
Like humans, insects possess sensory organs responsible for vision, hearing, smell, taste, and touch. For vision, insects primarily rely on compound eyes. But what about hearing? For example, crickets develop tympanal organs ...

Phys.org / Overheating bat boxes place bats in mortal danger during heat waves
Staying cool during heat waves is challenging for small creatures, but the problem could be even more extreme for nocturnal creatures that are unable to move to cooler locations while slumbering.

Phys.org / Researchers debunk new sex selection method
In 2019, a group of researchers in Japan published a study that promised the potential to revolutionize sex selection for scientists, farmers, and potentially even human fertility treatments.

Phys.org / Record spin waves thanks to flux quanta
Spin waves are considered to be promising candidates for a new form of electronics. Instead of electrons, the focus here is on magnons. These quantized units of spin waves describe how spin precession propagates. Similar ...

Phys.org / Large fluctuations in sea level throughout the last ice age challenge understanding of past climate
Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age, rather than just toward the end of that period, a study published in the journal Science has found.

Phys.org / Mitochondria play an unexpected role in regulating cell death, study reveals
A new study from The University of Texas at Arlington has revealed how cells control their mitochondria—the "energy producers" of cells—during the process of cell death. The discovery sheds light on how the body manages ...

Phys.org / Humans driving extinctions on scale not seen since dinosaurs, scientists say
Human activity may be triggering the greatest extinction event since the asteroid impact that wiped out the dinosaurs, according to scientists. Their study, based on a review of decades of research on environmental change, ...

Phys.org / Learning the language of lasso peptides to improve peptide engineering
In the hunt for new therapeutics for cancer and infectious diseases, lasso peptides prove to be a catch. Their knot-like structures afford these molecules high stability and diverse biological activities, making them a promising ...
