Brief firearm safety talks more than double openness to out-of-home storage‎

A brief chat about firearm safety can sharply increase willingness among gun owners to consider temporarily storing their firearms outside the home during times of crisis, a step that could help reduce suicide risk, according to a Rutgers-led study.

Belgium races to tame huge wildfire creeping toward Germany‎

Water-bombing aircraft and farmers' tractors joined forces Sunday to help firefighters tame Belgium's largest modern-day wildfire, which has scorched vast swaths of a hard-to-reach nature reserve near the German border.

Japan aims for the moons of Mars‎

Japanese scientists are readying a mission to Mars' moons to retrieve samples that may unlock the origins of the solar system and life on Earth, although a rival Chinese mission aims to make it back first.

A small squeeze reveals new clues about an unusual kind of magnet‎

Researchers at Rice University have found that gently squeezing a crystal of iron sulfide can change two of its unusual properties at the same time: its tiny magnetic signal and the way electricity moves through it. The result gives scientists a clearer picture of how a newly recognized class of magnetic materials works and suggests a simple way to control their behavior.

Gene-edited beagles produce no detectable major dog allergen, early tests find‎

Humans love dogs, but petting them can leave some people sneezing and wheezing. About 15% of the world's population lives with a dog allergy, which can increase the risk of hay fever and asthma. The main culprit is Can f 1, a protein found mainly in dog saliva. Right now, staying away from furry friends or getting regular immunotherapy shots or tablets is the only way to deal with the symptoms.

Phytophthora dieback linked to habitat loss and lower digging activity among quendas in Western Australia‎

A new study from Murdoch University has found that the introduced plant disease Phytophthora dieback is indirectly hindering quendas in Western Australia's jarrah forests by reducing their habitat quality and consequently decreasing their digging activity. The paper, "Exotic Plant Pathogen Reduces Habitat and Foraging Activities of a Digging Mammal," was published in the journal Austral Ecology.

Strain flips Hall signal in altermagnetic manganese telluride, suggesting a path to practical spintronics‎

Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with almost no overall magnetization. Such phases are highly prized for spintronics, where information is carried using the quantum spins of electrons.

Chinese ship sets off for Europe through Arctic, halving travel time‎

A Chinese container vessel has set sail for Europe through the Arctic as part of a new weekly service on a route that cuts shipment times in half but that environmental groups warn could speed up the melting of polar ice.
