An international physics team with the participation of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has proposed a new concept that may allow selected cosmic extreme processes to be studied in the laboratory in the future. A special setup of two high-intensity laser beams could create conditions similar to those found near neutron stars, for example. An antimatter jet is generated and accelerated very efficiently, as the experts report in the journal Communications Physics (DOI: 10.1038/s42005-021-00636-x).

Physicists of the Technische Universität Dresden introduce the first implementation of a complementary vertical organic transistor technology, which is able to operate at low voltage, with adjustable inverter properties, and a fall and rise time demonstrated in inverter and ring-oscillator circuits of less than 10 nanoseconds, respectively. With this new technology they are just a stone's throw away from the commercialization of efficient, flexible and printable electronics of the future. Their groundbreaking findings are published in the renowned journal "Nature Electronics".

POSTECH-Korea University joint research team develops a radiative cooling material that is transparent under direct sunlight.

Scientific substantiation to date indicates that indoor use of Pulze heated tobacco device is unlikely to present an indoor air quality issue or risk to bystanders, especially compared to existing background levels of toxicants, indoor air quality standards and pollutants in urban areas.

Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They are essential to preventing and treating infections, but they also pose a global threat to public health when microorganisms develop antimicrobial resistance. A University of Pittsburgh lab studied the mechanisms behind bacterial resistance to silver nanoparticles to determine if their ubiquitous use is a solution to this challenge or if it is perhaps fueling the fire.
