Our digital afterlife

(Arizona State University) It’s a problem unique to the 21st century: What happens to your digital self after you die? Social media pages and accounts often turn into memorials when someone dies, giving people a chance to still feel connected to those they’ve lost. But after we’re gone, who owns the information on our pages? Who can access them? Faheem Hussain, a clinical assistant professor at Arizona State University (ASU), will explore this topic in his discussion at the AAAS annual meeting.

DGIST increased the possibility of early diagnosis for neuro-developmental disorders

(DGIST (Daegu Gyeongbuk Institute of Science and Technology)) DGIST identified causes of hypersensitivity accompanied by neurodevelopmental disorder such as autism-spectrum disorder (ASD). This is expected to make huge contributions to the early diagnosis of sensory-defective symptom brought with neurodevelopmental disorder and cancer as well as the improvement of anti-cancer drug side effects.

Catalyst deposition on fragile chips

(Ruhr-University Bochum) Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst particles to tiny electrodes. It is inexpensive, simple and quick to perform. In order to characterize catalysts and test their potential for various applications, researchers have to fix the particles to electrodes so that they can then be examined, for example, with transmission electron microscopy.

Demonstration of world record transmission capacity over a 38-core 3-mode optical fiber

(National Institute of Information and Communications Technology (NICT)) The National Institute of Information and Communications Technology, Sumitomo Electric Industries, Ltd. and Optoquest Co., Ltd. succeeded in experimental transmission at 10.66 Pb/s, achieving a spectral efficiency of 1158.7 bps/Hz. This result exceeded the previous record of 10.16 Pb/s. We develop an optical fiber that supports the transmission of three transverse modes in 38 cores with reduced relative propagation delays between modes, and demonstrated its suitability for high spectral efficiency modulation, namely 256QAM and 64QAM.

The catalyst that removes CO2 and produces hydrocarbons

(FECYT – Spanish Foundation for Science and Technology) Water is split into hydrogen and oxygen by electrolysis, but if CO2 is also added to the mixture, compounds can be generated to make textiles, diapers and even spirits. American scientists, led by a Spaniard, have developed a catalyst that accelerates this reaction, while also removing a greenhouse gas.

KIST unveils the mystery of van der Waals magnets, a material for future semiconductors

(National Research Council of Science & Technology) The Korea Institute of Science and Technology (KIST) have announced that their team successfully controlled the magnetic properties of FGT (Fe3GeTe2) in a joint research project with for Basic Science(IBS) team. Fe3GeTe2 has recently attracted attention as a material for next-generation spintronic semiconductors.
