A single genetic switch can lead to rapid evolution in sea anemones

One genetic change governs whether certain cells of the starlet sea anemone shoot toxin-laden harpoons into prey or toss out sticky threads to anchor the organism in mud.

A single genetic switch can lead to rapid evolution in sea anemones
Jan. 12, 2021 , 2:40 PM
Anyone who has been stung by a jellyfish might think they know more than enough about cnidocytes, the cells that deliver the sting. But Leslie Babonis has found that these cells have much more to tell, including insight into a simple evolutionary mechanism that may enable jellyfish, sea anemones, corals, and their relatives collectively known as cnidarians to quickly adapt to new environments. Babonis has found that a single genetic switch can transform cells that sting into cells that cling, enabling the animal to colonize new surfaces. The work suggests this kind of switch may have helped power evolutionary transformations for hundreds of millions of ....

Many concussions don’t produce noticeable symptoms, leaving them likely to go undiagnosed and putting the injured at increased risk for lasting complications like brain damage.
A team of researchers led by University of Wisconsin-Madison mechanical engineer Christian Franck is working on better ways to detect concussions and better protective equipment to prevent them. ....
