A series of genetic variants can influence handedness, according to a new paper.

No, researchers have not discovered a “handedness gene.” But through brain imaging of 9,000 people in the United Kingdom, researchers devised a list of genetic variations that contribute to the way different brain processes end up on either side of the brain. This, in turn influences handedness—and can also influence whether someone will develop certain neurological diseases, according to the paper published in the journal Brain.

Researchers at King Abdullah University of Science and Technology have recently developed a flexible and imperceptible magnetic skin that adds permanent magnetic properties to all surfaces to which it is applied. This artificial skin, presented in a paper published in Wiley’s Advanced Materials Technologies journal, could have numerous interesting applications. For instance, it could enable the development of more effective tools to aid people with disabilities, help biomedical professionals to monitor their patients’ vital signs, and pave the way for new consumer tech.

“Artificial skins are all about extending our senses or abilities,” Adbullah Almansouri, one of the researchers who carried out the study, told TechXplore. “A great challenge in their development, however, is that they should be imperceptible and comfortable to wear. This is very difficult to achieve reliably and durably, if we need stretchable electronics, batteries, substrates, antennas, sensors, wires, etc. We decided to remove all these delicate components from the skin itself and place them in a comfortable nearby location (i.e., inside of eye glasses or hidden in a fabric).”

The artificial skin, developed under the supervision of Prof. Jürgen Kosel, is magnetic, thin and highly flexible. When it is worn by a human user, it can be easily tracked by a nearby magnetic sensor. For instance, if a user wears it on his eyelid, it allows for his eye movements to be tracked; if worn on fingers, it can help to monitor a person’s physiological responses or even to control switches without touching them.

For years, an enduring mystery has surrounded the Stuxnet virus attack that targeted Iran’s nuclear program: How did the U.S. and Israel get their malware onto computer systems at the highly secured uranium-enrichment plant?

The first-of-its-kind virus, designed to sabotage Iran’s nuclear program, effectively launched the era of digital warfare and was unleashed some time in 2007, after Iran began installing its first batch of centrifuges at a controversial enrichment plant near the village of Natanz.

The courier behind that intrusion, whose existence and role has not been previously reported, was an inside mole recruited by Dutch intelligence agents at the behest of the CIA and the Israeli intelligence agency, the Mossad, according to sources who spoke with Yahoo News.

A joint study by researchers at the National Institutes of Health (NIH) and the University of Maryland (UMD) has revealed a previously undocumented protective function of the telomerase enzyme.

Telomerase is used by somatic cells too

It was thought for a long time that telomerase is only active in certain cell types, such as stem cells, immune cells, and embryonic cells, in order to protect them from aging. Aside from a few cell types and, of course, cancer cells, which are able to hijack the telomerase enzyme in order to replicate uncontrollably, researchers believed that the enzyme is switched off in other types of cells.

Providing a glimpse the hidden workings of evolution, a group of researchers at UC Santa Barbara have discovered that embryos that appear the same can start out with surprisingly different instructions.

“We found that a lot of undercover evolution occurs in early embryos,” said Joel Rothman, a professor in the Department of Molecular, Cellular, and Developmental Biology, who led the team.

Indeed, although members of the same species are identical across the vast majority of their genomes, including all the genetic instructions used in development, Rothman and his colleagues found that key parts of the assembly instructions used when embryos first start developing can differ dramatically between individuals of the same species.
