Phys.org / In accidental discovery, scientists find flatworm can grow two heads and flip its body axis
The microscopic flatworm (Stenostomum brevipharyngium) is one of nature's weirder creatures. Chop off its head, and it'll grow one back. Cut it in half, and it'll become two separate healthy worms. And now scientists have ...
Phys.org / Discovery of a new principle: Chiral molecules adhere to magnets
A research group at The University of Tokyo has discovered a new principle by which helical chiral molecules acquire spin through molecular vibrations, enabling them to adhere to magnets. Until now, it was believed that chiral ...
Phys.org / Postcards from ancient Mars: Isotopes illuminate early Martian climate
A new analysis of chemical signatures measured by NASA's Curiosity Rover gives a peek at Mars's past to a time some 3.7 billion years ago, when it was warmer and wetter.
Phys.org / AI models for drug design fail in physics
State-of-the-art AI programs can support the development of drugs by predicting how proteins interact with small molecules. However, a new study by researchers at the University of Basel published in Nature Communications ...
Phys.org / Unit-free theorem pinpoints key variables for AI and physics models
Machine learning models are designed to take in data, to find patterns or relationships within those data, and to use what they have learned to make predictions or to create new content. The quality of those outputs depends ...
Phys.org / Ancient enzyme structure reveals new path to sustainable ethylene production
Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a key chemical in the production of many plastics.
Phys.org / Pre-construction archaeology reveals Benin City's historic urban development and heritage
Archaeological excavation in Benin City, Nigeria, ahead of the construction of the Museum of West African Art (MOWAA) has uncovered previously un-investigated sectors of the Kingdom of Benin's pre-colonial historic palace, ...
Phys.org / Nanobody-based antivenom shows effectiveness against 17 African snake species
Snakebite envenoming is among the world's deadliest yet most overlooked tropical diseases. The WHO has classified snakebite envenoming as one of 21 neglected tropical diseases, resulting in between 100,000 and 150,000 deaths ...
Phys.org / Lignin increases the stability and effectiveness of herbicide nanoparticles, study shows
A recent study has shown that a fraction obtained from lignin, an organic polymer responsible for the rigidity of plant cell walls, was able to improve the performance of nanoparticles with herbicide.
Phys.org / New species of trapdoor spider discovered, just in time for Halloween
Scientists at the University of California, Davis, have discovered a new species of trapdoor spider lurking in California's coastal sand dunes. The newly identified Aptostichus ramirezae is a close relative of Aptostichus ...
Phys.org / 'Molecular movie' capturing ribosome assembly shows how cells build life-sustaining protein factories
Ribosomes are the cell's protein factories, which read the genetic code and assemble the proteins that every organism needs to live. But as far as how ribosomes themselves were formed, tantalizingly little was known.
Phys.org / Preparation guide developed as Mars samples await transport to Earth
Mars is an inhospitable desert planet. Billions of years ago, things were different. In Jezero Crater, for example, fed by a vast river delta, there was probably a considerable body of water roughly the size of Lake Constance. ...
