Ultrathin metal layer boosts spin-related signals, opening a door to ultralow-power electronics

Researchers at Kyushu University have found that an ultrathin layer of iridium manganese (IrMn) can improve two spin-related signals in a structure made of a magnetic insulator and a platinum film. By examining how spin currents ...

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" ...

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 ...

150-year-old mystery about the identity of an 'extinct' giant crane solved

Scientists at Bournemouth University (BU) have solved a 150-year-old mystery about the identity of an extinct giant crane that lived in Europe over 20,000 years ago. The work is published in the journal Royal Society Open ...

New tissue atlas aims to help AI understand cancer

How cells are arranged within tissue can reveal as much about disease as the cells themselves. When doctors examine a cancer tumor, for example, they don't just look at which cells are present; they also want to know how ...
