New Rochelle, NY, Aug. 22, 2017 -- A new study looked at self-presentation of potentially damaging content on social media and examined whether this risky behavior is more likely associated with impulsivity and spontaneity or deliberate self-monitoring. The study results and differences found between British and Italian young adults are reported in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

MIPT researchers teamed up with their colleagues from the Kotelnikov Institute of Radio Engineering and Electronics (IRE) of the Russian Academy of Sciences (RAS) and the International Associated Laboratory of the Critical and Supercritical Phenomena in Functional Electronics, Acoustics, and Fluidics for a successful demonstration of a new kind of computer memory. Their paper was published in Applied Physics Letters.

CHAMPAIGN, Ill. -- Take a fish out of water and its stress hormones will go up. Adrenaline and noradrenaline, the "fight or flight" hormones, peak first, followed more gradually by cortisol. A new study finds that largemouth bass whose cortisol levels rise most after a brief bout of stress are inherently harder to catch by angling.

Many people report positive health effects from practicing yoga and meditation, and experience both mental and physical benefits from these practices. However, we still have much to learn about how exactly these practices affect mind-body health.

Inevitably, large stars at the end of their life collapse under the gigantic force of gravity, turning into black holes. We could cunningly ask if there is a way to delay this process; postpone the death of the star. While investigating "anti-aging therapy" of large stars, researchers at the Center for the Theoretical Physics of the Universe, within the Institute for Basic Science (IBS) conceptualized an ideal material that could store data for an exceptionally longer time than current short-lived devices, bringing new hints for future quantum memory technologies.

Troy, N.Y. - Results from its first run indicate that XENON1T is the most sensitive dark matter detector on Earth. The sensitivity of the detector -- an underground sentinel awaiting a collision that would confirm a hypothesis -- stems from both its size and its "silence." Shielded by rock and water, and purified with a sophisticated system, the detector demonstrated a new record low radioactivity level, many orders of magnitude below surrounding material on Earth.

A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices.

PRINCETON, N.J.--American children, no matter where they live or what school they attend, deserve to be guaranteed a quality education, much as we guarantee a safety net for seniors, argued Professor Marta Tienda of Princeton University's Woodrow Wilson School of Public and International Affairs. Without a federal guarantee to restore the "educational social contract," she wrote, the United States will never close educational achievement gaps or restore its schools to their former international preeminence.

It is not unusual that two similar scientific ideas on a particular phenomenon may echo each other across a long time span with the authors being not aware of each other. Such an unintentional duet over history illustrates the amazing beauty of science by clearly showing that progress of science is not necessarily a linear process, but it is often accumulative.

Even as robots become increasingly common across different parts of our world, they remain incredibly difficult to make. From designing and modeling to fabricating and testing, the process is slow and costly: even one small change can mean days or weeks of rethinking and revising important hardware.

But what if there was a way to let non-experts craft different robotic designs -- in one sitting?
