Northwestern Medicine scientists have discovered for the first time that the rhythm of breathing creates electrical activity in the human brain that enhances emotional judgments and memory recall.

These effects on behavior depend critically on whether you inhale or exhale and whether you breathe through the nose or mouth.

In the study, individuals were able to identify a fearful face more quickly if they encountered the face when breathing in compared to breathing out. Individuals also were more likely to remember an object if they encountered it on the inhaled breath than the exhaled one. The effect disappeared if breathing was through the mouth.

Ukrainian scientist Vladislav Kiselev claims that he has developed a type of battery that can power gadgets like smartphones and even cars for up to 12 years, without having to be recharged.

Kiselev, a senior researcher at the Institute of Bioorganic Chemistry and Petrochemistry in Kiev, and professor at Ukraine’s National Academy of Sciences, unveiled his intriguing battery prototype during the 2016 edition of Sikorsky Challenge, a prestigious international competition for research projects. The matchbox-like device looks fairly unimpressive, but the Ukrainian scientist claims that it has been continuously powering electrical devices for a year and four months without a single recharge, and will continue to do so for the next 11 years. That’s because his “battery” produces energy instead of simply storing it.

Robots have been a major focus in the technology world for decades and decades, but they and basic science, and for that matter everyday life, have largely been non-overlapping magisteria. That’s changed over the last few years, as robotics and every other field have come to inform and improve each other, and robots have begun to infiltrate and affect our lives in countless ways. So the only surprise in the news that the prestigious journal group Science has established a discrete Robotics imprint is that they didn’t do it earlier.

Editor Guang-Zhong Yang and president of the National Academy of Sciences Marcia McNutt introduce the journal:

In a mere 50 years, robots have gone from being a topic of science fiction to becoming an integral part of modern society. They now are ubiquitous on factory floors, build complex deep-sea installations, explore icy worlds beyond the reach of humans, and assist in precision surgeries… With this growth, the research community that is engaged in robotics has expanded globally. To help meet the need to communicate discoveries across all domains of robotics research, we are proud to announce that Science Robotics is open for submissions.

New report: rise of the machines: the dyn attack was just A practice run.

As the adversarial threat landscape continues to hyper-evolve, America’s treasure troves of public and private data, IP, and critical infrastructure continues to be pilfered, annihilated, and disrupted. The Mirai IoT botnet has inspired a renaissance in adversarial interest in DDoS botnet innovation based on the lack of fundamental security-by-design in the Internet and in IoT devices, and based on the lack of basic cybersecurity and cyber-hygiene best practices by Internet users.

The Goldilocks zone with telomere length is the key.

Ever since researchers connected the shortening of telomeres—the protective structures on the ends of chromosomes—to aging and disease, the race has been on to understand the factors that govern telomere length. Now, scientists at the Salk Institute have found that a balance of elongation and trimming in stem cells results in telomeres that are, as Goldilocks would say, not too short and not too long, but just right.

The finding, which appears in the December 5, 2016, issue of Nature Structural & Molecular Biology, deepens our understanding of and could help advance stem cell-based therapies, especially related to aging and regenerative medicine.

“This work shows that the optimal length for is a carefully regulated range between two extremes,” says Jan Karlseder, a professor in Salk’s Molecular and Cell Biology Laboratory and senior author of the work. “It was known that very short telomeres cause harm to a cell. But what was totally unexpected was our finding that damage also occurs when telomeres are very long.”
