In response to serious new security flaws found in almost every computer chip on the market today, researchers at Technische Universität Kaiserslautern, Germany, in collaboration with scientists at Stanford, have developed a mathematical algorithm to automate and expedite the process of finding flaws in future designs prior to production.
Cellulose soaked in a carefully designed polymer mixture acts as a sensor to measure pressure, temperature and humidity -- at the same time! The measurements are completely independent of each other. The sensor may be highly significant in fields such as robotics, healthcare and security.
Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of tools and technology used by gravitational wave scientists. Physicists at Louisiana State University measure quantum "back action" in the audio band at room temperature.
Ions move faster than atoms in the gas streams of a solar prominence. Scientists at the University of Göttingen, the Institut d'Astrophysique in Paris and the Istituto Ricerche Solari Locarno have observed this. The results of the study were published in The Astrophysical Journal.
Researchers develop a hydrogel whose stiffness and permeability to cells can be controlled with light
Although we're still a long way from commercial airplanes powered by a combination of fossil fuel and batteries, a recent feasibility study at the University of Illinois explored fuel/battery configurations and the energy lifecycle to learn the tradeoffs needed to yield the greatest reductions in carbon dioxide emissions.
A new method allows the quantum state of atomic 'qubits'--the basic unit of information in quantum computers -- to be measured with twenty times less error than was previously possible, without losing any atoms.
Puberty is a period of extensive changes of body morphology and function. As much as we are familiar with these life-altering changes, relatively little is known about what sets the whole process in motion. Thanks to studies in the tiny worm C. elegans, the group of Helge Großhans is getting closer to understanding how the onset of puberty is genetically controlled. Recently they uncovered a mechanism that initiates sexual organ maturation.
The Belle II detector got off to a successful start in Japan. Since March 25, 2019, the instrument has been measuring the first particle collisions, which are generated in the modernized SuperKEKB accelerator. The new duo produces more than 50 times the number of collisions compared to its predecessor. The huge increase in evaluable data means that there is not a greater chance of finding out why there is an imbalance between matter and anti-matter in the Universe.
Physicists from the University of Pennsylvania have developed a model that describes how individual parameters, like the variability in growth and the timing of cell division, can influence population dynamics in bacteria. Progress in this new field of study, which sits at the interface of math, physics, and biology, can help researchers better understand how individual-level metrics connect to population-level changes.
