New definition of domestication challenges traditional views on domestic species
Cats, dogs and farm animals are what come to mind when we think of domesticated animals. For ages, domestication has been portrayed as a uniquely human accomplishment, where species become domestic only through our deliberate ...
AI predicts bacterial resistance to cleaning agents
A group of researchers, including scientists from the DTU National Food Institute, have developed a method that, with the help of artificial intelligence and DNA decoding, can predict how well disease-causing bacteria such ...

How whisker-generated sounds are encoded in the auditory cortex of mice
Nestled in dark burrows, with a limited sense of vision, mice brush their whiskers against their environment to navigate and to detect objects around them. This behavior, termed whisking, has been extensively studied in the ...

Dual associations with two fungi found to improve tree fitness
When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal ...

Plants ignore gravity during droughts to forage for water
Roots "feel" gravity to extend and anchor themselves in the soil, but they can alter their growth direction toward a water source when needed. However, according to a new study by scientists at the Institute of Science and ...

Ancient ambidextrous protein breaks the rules of molecular handedness
A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an occurrence that has never ...
