Electrocatalysis is one of the most studied topics in the field of material science, because it is extensively involved in many important energy-related processes, such as the oxygen reduction reaction (ORR) for fuel cells, the hydrogen evolution reaction (HER) for green hydrogen production, and the oxygen evolution reaction (OER) for…

Like a snapshot, amber preserves bygone worlds. An international team of paleontologists from the University of Bonn has now described four new beetle species in fossilized tree resin from Myanmar, which belong to the Kateretidae family. They still exist today, with only a few species. As well as the about…

Discrete electronic states split-off from Bloch bands have been of interest for decades(1) and continue to be at the forefront of solid-state research and development because of their intimate connection with point defects in materials, such as dopant atoms and color centers, which exhibit nonclassical effects such as single photon…

These findings should have a significant impact on future vaccination strategies and pave the way for new treatments of an underperforming or over-reacting immune system. The results of this research are published in Cell Stem Cell on March 12, 2020. Stem cells in our bodies act as reservoirs of cells…

An analysis of publicly available data on infections from the new coronavirus, SARS-CoV-2, that causes the respiratory illness COVID-19 yielded an estimate of 5.1 days for the median disease incubation period, according to a new study led by researchers at Johns Hopkins Bloomberg School of Public Health. This median time…

If I were at risk of infection for novel coronavirus (COVID-19), how many days would I need to be quarantined before I was cleared? Research done by Dr. Lauer and Ms. Grantz of Johns Hopkins Bloomberg School of Public Health showed that the median period of incubation for COVID-19 was…

Magnetic (anti)skyrmions are microscopically small whirls that are found in special classes of magnetic materials. These nano-objects could be used to host digital data by their presence or absence in a sequence along a magnetic stripe. A team of scientists from the Max Planck institutes (MPI) of Microstructure Physics in…
