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 ...
Advanced gene editor enables more precise insertion of complete genes
Ask scientists which gene-editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of ...

Late Pleistocene horse DNA uncovers two-way migrations and climate-linked population declines
The horse originated in North America around four million years ago. As changing sea levels created land bridges between continents, the horse traveled into Eurasia. A team of 57 international researchers—including 18 Indigenous ...

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 ...

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 ...
