“#New technology speeds up organic data transfer” Credit: CC0 Public Domain Researchers are pushing the boundaries of data speed with a brand new type of organic LED. An international research team, involving Newcastle University experts, developed a visible light communication (VLC) setup capable of a data rate of 2.2 Mb/s by employing a new type…
“#A chemical tailor-made suit for Alzheimer’s drugs” Protein crystals of the human enzyme glutaminyl cyclase and atomic structure of the new inhibitor. Credit: Lisa-Marie Funk With over 1.2 million people affected in Germany alone and over 50 million people worldwide, Alzheimer’s disease, also referred to simply as Alzheimer’s, is one of the greatest medical and…
“#Solar Orbiter returns first data, snaps closest pictures of the Sun” Solar Orbiter spots ‘campfires’ on the Sun. Locations of campfires are annotated with white arrows. Credits: Solar Orbiter/EUI Team (ESA & NASA); CSL, IAS, MPS, PMOD/WRC, ROB, UCL/MSSL The first images from ESA/NASA’s Solar Orbiter are now available to the public, including the closest…
“#Pigs turn to humans as dogs do, unless they have a problem to solve” Credit: CC0 Public Domain Researchers of the MTA-ELTE ‘Lendület’ Neuroethology of Communication Research Group at the Department of Ethology at the Faculty of Science, Eötvös Loránd University, Budapest (ELTE) compared human-oriented communicative behaviors of young miniature pigs and dogs kept as…
“#Orderly arranged bead-chain ternary nanocomposites for supercapacitors” A schematic diagram of Cu2O-Mn3O4-NiO ternary nanocomposites preparation process. Compared with the traditional hydrothermal method, the materials prepared by electrospinning are nanostructure, which improved the electron transport capacity and the energy storage capacity of metal oxide. The acquired Cu2O-Mn3O4-NiO ternary nanocomposites were arranged in orderly metallic nanostructures, which…
“#N-doped carbon encapsulated transition metal catalysts to optimize performance of zinc-air batteries” Fe@NCG was be prepared by pyrolyzing solvent-free formed Fechitosan chelates and additional small molecule nitrogen source urea. The formed catalyst exhibits bifunctional catalytic performance toward ORR and OER in alkaline medium and higher power density and superior charge-discharge durability in zinc-air battery. Credit:…
“#Predicting the biodiversity of rivers” In the Swiss river Thur, environmental DNA samples from various locations were analyzed in order to make predictions on the biodiversity of the aquatic insects. Credit: Elvira Mächler, Chelsea Little, Florian Altermatt, University of Zurich Biodiversity is severely threatened both in Switzerland and worldwide, and numerous organisms are facing massive…
“#When the beach was off-limits to humans, a rare colony of seabirds found a place to nest” When the humans left, the seabirds flocked home. A rare colony of least terns, a threatened, federally protected seabird, landed on Deerfield Beach in March, when humans did not have access to the sand. This is the first…
