Phys.org / Rare bumble bee's downfall began long before effects from humans, study says
A rare North American bumble bee may have been on a path toward extinction long before modern human impacts, suggesting that its long-term genetic vulnerability made it especially fragile and less able to cope with both past ...
Phys.org / Gunboat diplomacy: How classic naval coercion has evolved into hybrid warfare on the water
Over the summer, the United States deployed warships to the Caribbean—ostensibly to menace drug traffickers but also as a none-too-subtle warning to Venezuela. Earlier in the year, a U.S. Navy destroyer bobbed along waters ...
Phys.org / New AI model for drug design brings more physics to bear in predictions
When machine learning is used to suggest new potential scientific insights or directions, algorithms sometimes offer solutions that are not physically sound.
Phys.org / Microbes at Red Sea vents show how life and geology shape each other
A study led by King Abdullah University of Science and Technology (KAUST) Professor Alexandre Rosado has revealed an unusual microbial world in the Hatiba Mons hydrothermal vent fields of the central Red Sea, a site first ...
Dialog / Long-term data-driven evidence reveals escalating rainfall extremes across urbanizing Himalayan foothills
For years, we believed the Himalayas were a climatic sanctuary—untouched, pristine, and resilient to the turbulence of modernization. But what happens when mountain cities begin to mimic the dynamics of megacities in the ...
Phys.org / National study finds public Montessori programs strengthen early learning outcomes—at sharply lower costs
The first national randomized trial of public Montessori preschool students showed stronger long-term outcomes by kindergarten, including elevated reading, memory, and executive function as compared to non-Montessori preschoolers.
Phys.org / The Southern Ocean may be building up a massive burp
The ocean has helped mitigate global warming by absorbing about a quarter of anthropogenic carbon dioxide (CO2) emissions, along with more than 90% of the excess heat those emissions generate.
Phys.org / Chemical networks can mimic nervous systems to power movement in soft materials
What if a soft material could move on its own, guided not by electronics or motors, but by the kind of rudimentary chemical signaling that powers the simplest organisms? Researchers at the University of Pittsburgh Swanson ...
Medical Xpress / Graying hair may reflect a natural defense against cancer risk
Throughout life, our cells are constantly exposed to environmental and internal factors that can damage DNA. While such DNA damage is known to contribute to both aging and cancer, the precise connection—particularly how ...
Phys.org / Under pressure: How a synchrotron helped reveal hidden differences in our DNA packaging
What happens when you squeeze DNA? Can pressure reveal something about how our genetic material is packed, protected, and accessed?
Phys.org / A mathematical 'Rosetta Stone' translates and predicts the larger effects of molecular systems
Penn Engineers have developed a mathematical "Rosetta Stone" that translates atomic and molecular movements into predictions of larger-scale effects, like proteins unfolding, crystals forming and ice melting, without the ...
Phys.org / How a pathogen disables plants' early warning system and kills crops
Scientists have discovered how one of the world's most destructive plant diseases manages to slip past crops' defenses—a breakthrough that could help farmers grow stronger, more resilient plants.
