Researchers have successfully realized logic gates using DNA crystallization, a huge step forward in DNA computing. Their findings have been published in the journal Advanced Materials. Using DNA’s double cross-like motifs as building blocks, they built complex 3D crystal architectures. Logic gates are implemented in these large assemblies of 3D DNA crystals, and the output … Leer más
A new study has found that electromagnetic radiation from satellites like Starlink hinders astronomers’ efforts to study radio waves in outer space. SpaceX has made significant contributions to space exploration and astronomy projects recently, most recently with the launch of the European Euclidean telescope. However, a recent international study found that SpaceX’s Starlink satellites are … Leer más
Elastic scattering measurements at hadron colliders allow a unique experimental approach to non-perturbation dynamics, which cannot be computed from first principles. In a remarkable run of the LHC, proton–proton elastic scattering events were recorded with integrated luminance using ATLAS’s ALFA detector. As part of the ATLAS Collaboration, physicists from the Institute of Nuclear Physics of … Leer más
The arrangement of electrons in matter, known as electronic structure, plays an important role in basic as well as applied research such as drug design and energy storage. However, the lack of a simulation technique that offers both high fidelity and scalability across different time scales and lengths has long been a barrier to the … Leer más
The universe is filled with gravitational waves. The collisions of massive objects like black holes and neutron stars create many of them. Now, astronomers are wondering about the environment in which these catastrophic events occur. Turns out they might need to look at quasars. The first detection of gravitational waves occurred in 2015. Since that … Leer más
Multi-object tracking (MOT) is a complex system consisting of several functional components, such as detection, visualization, and association. Association is in the final stages of the MOT process and is often seen as a core issue, aimed at connecting bounding boxes with existing small tracks. The linkage module makes inferences according to physical features, motion … Leer más
A research team has found that Nourseothricin, an older antibiotic, can be effective against resistant bacteria. Improved purification techniques have identified less toxic forms of antibiotics, namely Streptothricin-F, which show potent activity against gram-negative bacteria, by binding to a bacterial ribosomal subunit bacteria and cause translation errors, offering a unique approach to combating such infections. … Leer más
MIT physicists have successfully imaged pairs of particles in a cloud of atoms, providing new insights into the behavior of electrons in superconducting materials. The discovery, recorded in the journal Science, could aid understanding of superconductivity and further develop non-thermal electronics. (Artist’s concept.) The images shed light on how electrons forming superconducting pairs glide through … Leer más
One of the main ways cells «talk» to each other to coordinate essential biological activities such as muscle contraction, hormone release, nerve cell activation, digestion, and immune activation is through calcium signal. According to a new study published in the American Journal of Science and Technology, Rice University scientists used light-activated molecular machines to trigger … Leer más
