Phys.org / Wars between nations face persistent escalation risk, decades of conflict data suggest
Military leaders frequently underestimate how big the wars they engage in will get. Gen. Douglas MacArthur predicted U.S. troops could come home from the Korean War in time for Christmas, just months after the conflict started. ...
Phys.org / How to design a space habitat that supports its residents' mental health
In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room ...
Phys.org / Tropical trees show unexpected drought adaptability across Puerto Rico's rainfall extremes
Tropical forests store enormous amounts of carbon and harbor most of the world's terrestrial biodiversity, but scientists fear that increasingly severe droughts threaten their ability to survive and continue absorbing carbon ...
Phys.org / Chemical fingerprints reveal hidden binary pasts of massive stars
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...
Phys.org / Immune 'reprogramming' could protect poultry from deadly diseases without antibiotics
University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. ...
Phys.org / Radiation vest tested on NASA moonshot can cut astronauts' exposure in solar storms, study suggests
A new study suggests a protective vest tested on a manikin during NASA's first Artemis moonshot could drastically cut the radiation exposure of lunar astronauts during severe solar storms.
Phys.org / Rangers and scientists map vulnerable reefs in the remote Groote Archipelago
For thousands of years, the Anindilyakwa people have lived in deep connection with the waters surrounding Groote Eylandt, a remote island in the Gulf of Carpentaria.
Phys.org / Arctic cyclone clusters batter sea ice, leaving coasts more exposed to storms
In the Arctic, weather plays a key role in determining how much ice covers the ocean. Arctic cyclones are one weather phenomenon with a significant influence, causing unusually warm and stormy conditions that typically lead ...
Phys.org / Oxytocin nudges distrustful men to invest 15% more in anonymous trust game
In 2005, a research team led by University of Zurich economics professor Ernst Fehr published a study in the journal Nature that provided evidence for the first time that intranasally administered oxytocin can increase trusting ...
Phys.org / Bumblebees can learn to associate new smells with their queen
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For ...
