Brutish and Short? DNA 'switch' Sheds Light on Neanderthals

By Sharon Begley NEW YORK (Reuters) - How can creatures as different in body and mind as present-day humans and their extinct Neanderthal cousins be 99.84 percent identical genetically? Hundreds of Neanderthals’ genes were turned off while the identical genes in today’s humans are turned on, the international team announced in a paper published online in Science. They also found that hundreds of other genes were turned on in Neanderthals, but are off in people living today.

Key Brain 'Networks' May Differ in Autism, Study Suggests

WEDNESDAY, April 16, 2014 (HealthDay News) — Differences in brain connectivity may help explain the social impairments common in those who have autism spectrum disorders, new research suggests. The small study compared the brains of 25 teens with an autism spectrum disorder to those of 25 typically developing teens, all aged 11 to 18. “It is generally agreed that the way the networks are organized is not typical [in those with autism],” explained study lead researcher Inna Fishman, assistant research professor of psychology at San Diego State University.

Should Scientists Be Killing Species They Thought Were Extinct?

In May 2006, in the Himalayan foothills of northern India, an astronomer and ecologist named Ramana Athreya caught two of an elusive bird species in a mist net. Now, this sounds crazy when you learn it out of context, but here’s what Athreya should have done, according to 250 years of scientific protocol: immediately kill those animals. Having the bird in hand has been the essential means of defining a species, both for the original scientific description and as source material for later researchers.

Study Finds No Evidence of Heartbleed Attacks Before the Bug Was Exposed

SAN FRANCISCO — Ever since the Heartbleed bug was exposed last week, the question everyone has been asking is: Did anyone exploit it before a Google researcher first discovered it? The worry is that in the two years since the bug was accidentally incorporated into OpenSSL — a crucial piece of free security software used by governments and companies like the F.B.I. and Google — attackers could have exploited Heartbleed to take sensitive information like passwords and the virtual keys used to decipher any scrambled information stored on a web server. But security researchers at the Energy Department’s Lawrence Berkeley National Laboratory, which conducts unclassified scientific research, say that it is still possible to look for past Heartbleed exploitations by measuring the size of any messages sent to the vulnerable part of the OpenSSL code, called the Heartbeat, and the size of the information request that hits a server.

Paleontologists Discover Land Herbivores' Earliest Ancestor

Paleontologists unearthed the oldest ancestor of land-dwelling herbivores with the discovery of a 300-million-year-old skeleton, shedding light onto plant eaters’ emergence on land, a study said Wednesday. A partial fossil of the animal, called Eocasea martini, is “the first link between carnivores and herbivores, the transition,” Robert Reisz, the article’s principal author and professor at Canada’s University of Toronto Mississauga, told AFP. Eocasea was a carnivore, but had certain skeletal features that indicate it was a close relative of herbivores, Reisz said.

ACAPULCO, Mexico (AP) — A powerful, magnitude-7.5 earthquake shook central and southern Mexico on Friday. The U.S. Geological Survey said it was centered northwest of the Pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday.
