Phys.org / Beer and cannabis could share 'sex switch,' study finds
Researchers at University College Dublin have identified a genetic "switch" that determines the sex of cannabis plants, and found the same system may exist in hops. The study, published in New Phytologist, pinpoints a specific ...
Phys.org / Why stars spin down, or up, before they die
From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they "spin down." The sun's total angular momentum has declined as material is gradually blown off at the surface ...
Phys.org / Light-based scans reveal how cells can be stable yet adaptable
Our cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers have used ...
Phys.org / Specially designed material combines light and electricity to remove PFAS from water without harmful byproducts
Researchers at Clarkson University have reported a breakthrough in tackling per- and polyfluoroalkyl substances (PFAS), a group of widely used "forever chemicals" that are difficult to remove from water and have raised growing ...
Phys.org / Better volcano eruption predictions on Earth—and Venus—thanks to Mauna Loa study
When Mauna Loa erupted in 2022, the largest lava flow headed on a path headed directly toward Daniel K. Inouye State Highway 200, also known as Saddle Road, a critical route that carries many residents from their homes on ...
Phys.org / Detailed DNA repair snapshots reveal how BRCA-linked cancer cells may survive
Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a finding that could reveal ways to inhibit the effects of BRCA1 and BRCA2 mutations that heighten the ...
Phys.org / Machine learning offers faster, more reliable analysis of Fermi surfaces in search of spintronic materials
The search for next-generation electronic materials often starts with studying the Fermi surface, which serves as a map of a material's electronic structure. Its shape varies with crystal structure, composition, and electronic ...
Phys.org / Synchrotron safety monitoring sheds light on dark photons
A scientist from Tokyo Metropolitan University has proposed using safety monitoring at synchrotron facilities to study the properties of dark photons, hypothetical particles proposed to explain dark matter. Calculations show ...
Phys.org / Location, location, location: How the Nile helped an ancient Sudanese city thrive for centuries
The ancient city of Napata, located in what is now Sudan, was a major urban and cultural center of Kush, an ancient empire in Nubia. University of Michigan archaeologists and earth scientists examined the land underlying ...
Phys.org / Small differences in cell structures called microtubules determine how well cancer drug performs
A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has uncovered the mechanism underlying how cancer patients respond to a widely used cancer drug, ...
Phys.org / Time-evolving polymer recreates nature's signature twist
Science has long taken inspiration from the natural world, and few natural designs are as iconic as the helical shape that makes life possible. The best-known example of such a molecule is DNA, a double helix that carries ...
Phys.org / Amazon safeguards cut deforestation but miss rising forest degradation threat
Antonio has spent the past seven years running toward fires that most others run from. A firefighter in the Brazilian Amazon since 2019, he works inside the Chico Mendes Extractive Reserve, one of the most biodiverse places ...
