FILE - This 2014 file electron microscope image made available by the Centers for Disease Control and Prevention shows numerous, spheroid-shaped enterovirus-D68 (EV-D68) virions. Scientists have found the strongest evidence yet that a virus is to blame for a mysterious and rare illness, called acute flaccid myelitis or AFM, that can start like the sniffles but quickly paralyze children. University of California, San Francisco, researchers tested how the immune system fought back and found clear signs that an enterovirus, a common seasonal virus that specialists have suspected, was indeed the culprit. The the Centers for Disease Control and Prevention noted that AFM spikes coincided with seasons when certain strains of enteroviruses - EV-D68 and EV-A71 - were causing widespread respiratory illnesses.

File-Picture taken in August 2017 show linear clusters of trilobites (arthropods) on the surface of the rock slab. These fossils come the Fezouata Shale in Morocco (near Zagora). Their age is 480 million years. The trilobites are all oriented towards the same direction. The head part has a long spine in the front. There are also two lateral spines along the animal's body.

ADDS THAT THE GROUP HAS PULLED THE VIDEO This image made from the National Academy of Sciences website on Wednesday, Oct. 2, 2019 shows part of a video of people discussing gene editing and designer babies. The group pulled the video and issued an apology after some criticism. The video gives the inaccurate impression that gene editing can give positive traits without any potential downsides - “the definition of hubris,” said Harvard Medical School dean Dr. George Q. Daley, who also has been involved in academy work. “We are not there yet.” (National Academy of Sciences via AP)

A government-funded group that’s leading efforts to set standards for gene editing has pulled a video it posted in the wake of concern about how it portrayed the ethically dicey science and its possible use to make designer babies. The National Academy of Sciences posted the video earlier this week...
