How a tiny mutation in the ARHGAP11B #gene helped grow our big human #brain

How a tiny mutation in the ARHGAP11B #gene helped grow our big human #brain | Limitless learning Universe | Scoop.it

After splitting from the chimpanzee lineage, a single letter of our genome switched to another – and likely shaped the evolutionary expansion of the human.

 

The gene ARHGAP11B promotes basal progenitor amplification and is implicated in neocortex expansion. It arose on the human evolutionary lineage by partial duplication ofARHGAP11A, which encodes a Rho guanosine triphosphatase–activating protein (RhoGAP). However, a lack of 55 nucleotides in ARHGAP11B mRNA leads to loss of RhoGAP activity by GAP domain truncation and addition of a human-specific carboxy-terminal amino acid sequence.

 

Scientists now show that these 55 nucleotides are deleted by mRNA splicing due to a single C→G substitution that creates a novel splice donor site. They reconstructed an ancestral ARHGAP11B complementary DNA without this substitution. Ancestral ARHGAP11B exhibits RhoGAP activity but has no ability to increase basal progenitors during neocortex development. Hence, a single nucleotide substitution underlies the specific properties of ARHGAP11B that likely contributed to the evolutionary expansion of the human neocortex.

Is this a case of progressive evolution? I think this is a clear case of random error: just a sigle base change (C for G) with such a great impact.

#FF Three serious #Linux kernel security holes patched | #Update asap!!! | #CyberSecurity | Limitless learning Universe | Scoop.it
The good news is developers are looking very closely at Linux's core code for possible security holes. The bad news is they're finding them.

At least the best news is that they're fixing them as soon as they're uncovered.

The latest three kernel vulnerabilities are designated CVE-2016-8655, CVE-2016-6480, and CVE-2016-6828. Of these, CVE-2016-8655 is the worst of the bunch. It enables local users, which can include remote users with virtual and cloud-based Linux instances, to crash the system or run arbitrary code as root.

#adventure In the Deep of the #Oceans, Clues Hide about How Life Makes #Light

#adventure In the Deep of the #Oceans, Clues Hide about How Life Makes #Light | Limitless learning Universe | Scoop.it

Bioluminescent organisms have evolved dozens of times over the course of life’s history. Recent studies are narrowing in on the complicated biochemistry needed.

 

Dive deep enough under the surface of the ocean, and light reigns. Some 90 percent of the fish and crustaceans that dwell at depths of 100 to 1,000 meters are capable of making their own light. Flashlight fish hunt and communicate with a flashing Morse code sent by light pockets that pulse under their eyes.

 

Tubeshoulder fish shoot luminous ink at their attackers. Hatchetfish make themselves appear invisible by generating light on their underbellies to mimic downwelling sunlight; predators prowling below look up to see only a continuous glow.

Scientists have indexed thousands of bioluminescent organisms across the tree of life, and they expect to add many more. Yet researchers have long wondered how bioluminescence came to be. Now, as explained in several recently released studies, researchers have made significant progress in understanding the origins of bioluminescence — both evolutionary and chemical. The new understanding may one day allow bioluminescence to be used as a tool in biology and medical research.

 

One longstanding challenge has been determining how many separate times bioluminescence arose. How many species came to the same conclusion, independent of one another Though some of the most familiar examples of light from living organisms are terrestrial — think of fireflies, glowworms and foxfire — the bulk of evolutionary events involving bioluminescence took place in the ocean. Bioluminescence is in fact markedly absent from all terrestrial vertebrates and flowering plants.

 

In the deep ocean, light gives organisms a unique way to attract prey, communicate and defend themselves, said Matthew Davis, a biologist at St. Cloud State University in Minnesota. In a study released in June, he and his colleagues found that fish that use light for communication and courtship signaling were especially diverse. Over a period of about 150 million years — brief by evolutionary standards —such fish proliferated into more species than other groups of fish. Bioluminescent species that used their light exclusively for camouflage, on the other hand, were no more diverse.

#Physicists confirm the precision of magnetic fields in the most advanced #stellarator in the world

#Physicists confirm the precision of magnetic fields in the most advanced #stellarator in the world | Limitless learning Universe | Scoop.it
Physicist Sam Lazerson of the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) has teamed with German scientists to confirm that the Wendelstein 7-X (W7-X) fusion energy device called a stellarator in Greifswald, Germany, produces high-quality magnetic fields that are consistent with their complex design.

The findings, published in the November 30 issue of Nature Communications , revealed an error field—or deviation from the designed configuration—of less than one part in 100,000. Such results could become a key step toward verifying the feasibility of stellarators as models for future fusion reactors.

W7-X, for which PPPL is the leading U.S. collaborator, is the largest and most sophisticated stellarator in the world. Built by the Max Planck Institute for Plasma Physics in Greifswald, it was completed in 2015 as the vanguard of the stellarator design. Other collaborators on the U.S. team include DOE's Oak Ridge and Los Alamos National Laboratories, along with Auburn University, the Massachusetts Institute of Technology, the University of Wisconsin-Madison and Xanthos Technologies.
