Medical Xpress / Immune cells may have a biological memory that makes weight loss harder after obesity
According to the World Health Organization, one in eight people lives with obesity. Yet despite numerous health education programs, books, articles and treatments, many individuals still struggle to lose weight once they ...
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 / Small molecular substitutions reshape energy pathways behind aggregation-induced emission
Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.
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, ...
Phys.org / Hubble tracks new decagon encircling Saturn's south pole
Recent observations with NASA's Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn's south pole. This discovery marks the first time a large, regular-sided jet pattern has ...
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 / Researchers tune into Arctic under-ice sounds and test through-ice communication
Beneath the Arctic Ocean is an orchestra featuring natural and human composers, from cracking sea ice and whistling beluga whales to humming shipping-vessel engines. Researchers from MIT Lincoln Laboratory heard some of this ...
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 ...
Phys.org / AI suggests new physics experiments that could outperform human-designed setups
Research means asking questions of the universe. For centuries, clever minds have advanced science by devising ingenious experiments designed so their results reveal something about the laws of nature as clearly and unambiguously ...
Phys.org / In ant nervous systems, gene expression may drive rescue behavior
Why do some ants help nestmates in distress while others don't? A research team from Johannes Gutenberg University Mainz (JGU) and Tel Aviv University addressed this question in a new study. The researchers examined worker ...
Phys.org / Switching gravity on and off leaves particles behind, mathematical model finds
Hawking radiation causes black holes to eventually evaporate. This is because particle pairs are spontaneously created near the event horizon (the position of the last ray of light that can escape the black hole's gravitational ...
Phys.org / Neutron bone imaging brings T. rex to life
A broken rib from Scotty, the largest T. rex skeleton discovered, is helping scientists uncover new information about life on Earth 66 million years ago. Scotty's rib preserves something rarely seen in the fossil record: ...
