Atomic magnetism reveals why iron, but not chromium, can produce ammonia using sunlight

Two nearly identical materials have completely different chemical behavior. Research teams at the University of Vienna and TU Wien studied catalysts that use the energy of sunlight to produce ammonia. Surprisingly, when the ...

Molecular architecture determines tomato plant resistance to its main pest

An international study investigating why wild tomatoes are more resistant to the tomato leafminer (Phthorimaea absoluta) than cultivated varieties revealed that the secret lies in the spatial structure of a plant defense ...

Explaining the difference between brittle and ductile behavior in polymer glasses

Glasses are (mostly) brittle, metals can be ductile (plastic), and liquids flow easily. Polymers are interesting because they exhibit all three types of behavior, depending on their chemical nature, temperature, and deformation ...

Chornobyl dog population shows genetic signatures of directional selection

The latest research on the wild population of dogs in Chornobyl reveals that the genetic differences between these dogs and other similarly isolated dog populations are likely evidence of directional selection, not mutation. ...

Could next-gen artificial intelligence help map out future space outposts?

Planning a successful trip can be challenging, especially when your destination is in outer space. Even before liftoff, space missions require extraordinary amounts of scientific preparation and data analysis to succeed, ...

Same radical, different paths: X-ray snapshots reveal how neighboring molecules shape its movement

Chemical reactions have their own "impatient molecules." Unable to stay still even for a moment, they latch onto other molecules indiscriminately. Researchers have now found that even these molecules change where they "sit" ...

Schools increasingly affected by poor air quality as wildfire smoke becomes more common

American children are increasingly exposed to air pollution as wildfire smoke becomes more common, and some schools and child care centers struggle to keep indoor breathing conditions clean, a new national study shows.

Rarely seen deep-sea barreleye fish filmed in 4K

During a recent expedition aboard the research vessel David Packard, MBARI scientists encountered a rarely seen barreleye fish (Macropinna microstoma). This sighting is MBARI's 11th observation of this unique deep-sea fish ...
