Phys.org / High levels of forever chemicals found in Svalbard reindeer

Svalbard reindeer live in a place so remote they have actually evolved to become a subspecies. But that remoteness isn't enough to protect them from contaminants from the industrial world.

Phys.org / African swine fever: A novel model assesses transmission between domestic pigs and wild boar

African swine fever (ASF) is one of the most devastating diseases affecting domestic pigs and wild boars worldwide. Since its introduction into Europe, this deadly virus has spread widely, threatening pig production and causing ...

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 / New AI method flags fluid flow tipping points before simulations break down

David J. Silvester, a mathematics professor at the University of Manchester, has developed a novel machine-learning method to detect sudden changes in fluid behavior, improving speed and the cost of identifying these instabilities ...

Phys.org / A smarter way to build vaccines: Scientists harness AI to target emerging alphaviruses

A team of scientists at The University of Texas Medical Branch (UTMB), led by Nikos Vasilakis, Ph.D., and Peter McCaffrey, MD, has developed a new computational pipeline that could dramatically accelerate the development ...

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 / Rock bonding changes understanding of earthquake mechanics

When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is suddenly released—resulting in an earthquake. What exactly governs this behavior remains one of the ...

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 / 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 / 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 / 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 / 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, ...
