Mar 20, 2023 (Nanowerk News) Security gaps exist not only in software, but also directly in hardware. Attackers might deliberately have them built in in order to attack technical applications on a large scale. Researchers at Ruhr University Bochum, Germany, and the Max Planck Institute for Security and Privacy (MPI-SP)...
Life on distant moons
Mar 20, 2023 (Nanowerk News) Liquid water is one of the most important ingredients for the emergence of life as we know it on Earth. Researchers of the ORIGINS Cluster from the fields of astrophysics, astrochemistry and biochemistry have now determined in a novel, interdisciplinary collaboration the necessary properties that...
Instrument adapted from astronomy observation helps capture singular quantum interference effects
Mar 20, 2023 (Nanowerk News) By adapting technology used for gamma-ray astronomy, a group of experimental researchers has found that X-ray transitions previously thought to have been unpolarized according to atomic physics, are in fact highly polarized, reports a new study published in Physical Review Letters ("Strong Polarization of a...
Novel strategy drives the intracellular uptake of lipid nanoparticles for photodynamic therapy
Mar 16, 2023 (Nanowerk News) In order to deliver cancer therapeutics to tumor cells, the cells’ membranes must be overcome. A team of researchers have discovered a simple way to achieve this using lipid nanoparticles containing the reagent EDTA (ethylenediaminetetraacetic acid). As the team reports in the journal Angewandte Chemie...
Scientists develop energy-saving, tunable meta-devices for high-precision, secure 6G communications
Mar 16, 2023 (Nanowerk News) The future of wireless communications is set to take a giant leap with the advent of sixth-generation (6G) wireless technology. A research team at City University of Hong Kong (CityU) invented a groundbreaking tunable terahertz (THz) meta-device that can control the radiation direction and coverage...
A fundamental physical concept allows OLED displays with more brilliant colors
Mar 16, 2023 (Nanowerk News) A research team from the University of Cologne (Germany) and the University of St Andrews (Scotland) has shown in a new study how a fundamental physical concept can be used to boost the colour brilliance of smartphone, computer or TV screens without cutbacks in energy...
Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition
Mar 17, 2023 (Nanowerk News) Ice surfaces have a thin layer of water below its melting temperature of 0 °C. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e....
New gene-editing technique reverses vision loss in mice
Mar 17, 2023 (Nanowerk News) Researchers in China have successfully restored the vision of mice with retinitis pigmentosa, one of the major causes of blindness in humans. The study, to be published in the Journal of Experimental Medicine ("Vision rescue via unconstrained in vivo prime editing in degenerating neural retinas"),...
Stalactites and stalagmites in the battery?
Mar 17, 2023 (Nanowerk News) They are considered the "Holy Grail" of battery research: so-called "solid-state batteries". They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult...
Double-helix unzipping reveals DNA physics
Mar 17, 2023 (Nanowerk News) Reconstructing accurately how the parts of a complex molecular are held together knowing only how the molecule distorts and breaks up. This was the challenge taken on by a research team led by SISSA’s Cristian Micheletti and recently published on Physical Review Letters ("Nonequilibrium Thermodynamics...
