Phys.org / A snake-headed vessel hints at a mysterious Roman cult
The ancient Romans were a deeply religious and superstitious people, worshiping dozens of cults—some official and others secretive. One of these was dedicated to Sabazios, a deity from Thrace and Phrygia (regions spanning ...
Dialog / Making superconductors thinner can change how they accommodate magnetic fields
What happens when a superconductor becomes so thin that electrons can no longer behave as if they were moving through an ordinary three-dimensional piece of metal? This question has been at the center of my recent work on ...
Phys.org / Eight-letter DNA alphabet is accurately transcribed by a natural enzyme
All known life on Earth uses the same genetic alphabet, consisting of four letters. Now, researchers at the University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately ...
Phys.org / Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost
Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release ...
Medical Xpress / Neural networks reveal how experience shapes learning in both brains and machines
A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens—both in machines and in living brains.
Medical Xpress / 3D atomic-level snapshots reveal ketamine binds to human opioid receptors
Ketamine, a drug approved for medical use in 1970 as a short-acting anesthetic, including during the Vietnam War for battlefield surgery, is still a pharmacological mystery. For a long time, scientists knew that ketamine, ...
Phys.org / First switchable graphene nanoribbon that twists on demand
Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted ...
Phys.org / Predictive tools can confuse rare mutations with dangerous ones
When a patient's DNA is read, it is compared with a reference version of the human genome. This allows geneticists and rare disease experts to look at a list of places where the patient's DNA differs. Most variations will ...
Phys.org / Resin-mounted wallaby teeth reveal rare 1,200-year-old ornaments in Queensland
While sorting through animal bones in a rock shelter in Queensland, Australia, archaeologists came across a tooth where something was "not quite right." Stuck to the tip of its root was a blackish-brown ball of glue-like ...
Phys.org / Mammalian genes can combine to make previously unknown mRNAs and proteins
For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries instructions for a single kind of protein. Now, researchers at Harvard Medical School have discovered that instructions ...
Phys.org / Built to last or break down: Ring size tunes biodegradable plastic lifetimes
Biodegradable plastics should be tough enough for use yet able to break down at an appropriate rate afterward. Researchers at the University of Osaka show that changing the size of rings threaded onto a biodegradable polymer ...
Phys.org / New 'devil flower' species discovered in Thai national park
Researchers have described a new species of leafless flowering plant found on the forest floor of a national park in western Thailand, and its otherworldly appearance has earned it a fittingly dramatic name: Thismia daemona, ...
