Phys.org / Mathematical signature spots when competition is fair, winner-take-all, or too soft
A University of Houston researcher and his collaborators have developed a mathematical model that helps identify whether a competitive environment is healthy, stagnant or skewed. Published in the journal npj Complexity, the ...
Phys.org / Wildlife trade increases pathogen transmission: What 40 years of data say about spillover
Hedgehogs, elephants, pangolins, bears or fennec foxes: many wild species are sold as pets, hunting trophies, for traditional medicine, biomedical research, or for their meat or fur. These practices, whether legal or illegal, ...
Phys.org / How an internal plant 'thermostat' guides root growth in unpredictable temperatures
Plants can't move to escape the heat like humans can; they are forced to adapt. As temperatures fluctuate, one key survival strategy is the ability of roots to keep growing, allowing plants to access water and nutrients farther ...
Phys.org / How surface chemistry impacts the performance of malaria nets
Insecticide-treated bed nets remain one of the most effective tools in malaria prevention, acting both as a physical barrier and as an insecticidal surface that kills or disables mosquitoes before they can transmit disease. ...
Phys.org / Examining embryo model ethics beyond box-checking
In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...
Phys.org / Decoy molecules trick soil bacteria into attacking persistent pollutants without genetic engineering
In a study published in the Journal of Materials Chemistry A, Nagoya University researchers demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent ...
Phys.org / Keeping up with the phages: How V. cholerae neighbors swap defenses against viruses
Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems. Previous work has shown that V. cholerae carries a large genetic element called ...
Phys.org / Ant larvae control parental care by using odor signals
In the clonal raider ant (Ooceraea biroi), workers in a colony alternate between caring for larvae and laying eggs in a coordinated cycle. Researchers at the Max Planck Institute for Chemical Ecology in Jena have discovered ...
Phys.org / AI trained like a Rubik's Cube solver simplifies particle physics equations
For years, Rutgers physicist David Shih solved Rubik's Cubes with his children, twisting the colorful squares until the scrambled puzzle returned to order. He didn't expect the toy to connect to his research, but recently ...
Phys.org / The lengths male octopuses go to protect the arm they need to mate
For mating male octopuses, one limb is more important than all others. That is the third right arm or hectocotylus, which is used to transfer sperm to the female because the penis cannot do it directly. Losing the limb can ...
Phys.org / Physicists zero in on the mass of the fundamental W boson particle
When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about ...
Phys.org / AI uncovers hidden immune defenses inside bacteria
Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...
