Phys.org / How changing environments can preserve an ancient microbial survival strategy
A research group led by Tetsuhiro Hatakeyama from the Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo has revealed how a seemingly self-destructive survival strategy could persist in yeast for hundreds ...
Phys.org / Light reveals transient electronic step behind a hidden state in metal-organic framework
A fleeting photoinduced electronic state and the subsequent formation of a photoinduced hidden state in a metal–organic framework were captured in just 30 femtoseconds by researchers at Science Tokyo, Tohoku University and ...
Phys.org / Research cautions that sometimes working together can actually spur inequality
Encouraging people to contribute to a common good can have a surprising drawback: a risk that rewards become concentrated among a smaller group, putting the rest at a disadvantage. Put more simply, "equality and cooperation ...
Phys.org / Hidden DNA copying may give bacteria a faster route to antibiotic resistance
The dangers of antibiotic overuse have become increasingly clear in recent decades. Excessive use accelerates the evolution of bacterial resistance to antibiotics, raising the alarming prospect of infections that no longer ...
Phys.org / Burning soil and peat drove most emissions in Canada's record 2023 wildfire season, study finds
Most of the carbon released during Canada's record-breaking 2023 wildfire season came from burning soil and peat, rather than trees, according to new research from McMaster University.
Phys.org / Biodegradable implant can deliver targeted cancer immunotherapy while protecting healthy tissue
Scientists at Houston Methodist Research Institute have developed a biodegradable implant designed to deliver cancer-fighting immunotherapy drugs directly into tumors over an extended period, a strategy that could improve ...
Phys.org / First 3D views explain how primate cone pigments distinguish red from green
Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green ...
Phys.org / Plants know when to grow—and when to hold back, study finds
Researchers have uncovered a surprising mechanism that allows plants to carefully coordinate the formation and growth of new leaf parts. The study shows that the hormone auxin regulates different phases in organ formation ...
Phys.org / New snail species bolster case for protecting Montenegro's biodiversity
The descriptions of the two new additions to the European snail fauna, named Cochlostoma komarnica and Cochlostoma dobrido, have been published in the open-access Biodiversity Data Journal.
Phys.org / Biomolecular condensates reveal surprising activity as catalysts
Biomolecular condensates are ubiquitous in living cells, including bacteria, viruses, plants and mammalian systems. These membraneless bodies, or molecular communities made up of DNA, RNA and proteins, are where molecules ...
Phys.org / Moth wings reveal an unexpected ability to smell plant chemicals
Insect wings are bristling with senses, feeling the wind blowing and even tasting potential mates, but little was known about whether moth wings are equipped with a sense of smell. Sonja Bisch-Knaden and Bill Hansson from ...
Phys.org / AI and robotics accelerate search for better gut microbiome therapies
Biomedical engineers at Duke University have demonstrated a method for systematically developing novel, complex combinations of probiotics and prebiotics to more effectively maintain gut health and treat various gastrointestinal ...
