Octopuses Edit Their Genetic Code Like No Other Animal

Posted on Categories Discover Magazine

New research into the cephalopod genome is undermining our assumptions about evolution, and the role that DNA mutations play in updating a species' physiology. Researchers from the Marine Biological Laboratory in Woods Hole and Tel Aviv University have been studying how cephalopods — squids, octopuses, cuttlefish and nautiluses — edit their genome, and found that instead of relying on DNA mutations to adapt, they have the ability to make changes to their RNA, the genetic "messe ...read more

Dogs Don’t Process Language With Their Left Brains, After All

Posted on Categories Discover Magazine

A case of left-right confusion misled researchers about how dogs process language. Last August, Hungarian neuroscientists Atilla Andics and colleagues reported that the left hemisphere of the dog brain is selectively activated in response to the lexical properties (i.e. the meaning) of spoken words. This result was very interesting, not least because lexical processing is also lateralized to the left hemisphere in most humans. The paper appeared in the prestigious journal Science. However, ...read more

Sizzling Exoplanet Has an Atmosphere, Opening Avenues for Finding Alien Life

Posted on Categories Discover Magazine

On the list of exoplanets that could hold life, GJ 1132b wouldn’t come near making the cut. It’s a super-Earth whose upper atmosphere reaches 500 degrees Fahrenheit (260 degrees Celsius), meaning it only gets hotter as you move down. It’s barely a hair away from its star, completing a year in 1.6 Earth days. Life is incredibly unlikely to survive there. Yet it may be one of the most important planets to come along in the search for life. So why’s that? Well, it’s ...read more
