Researchers at St. Jude Children's Research Hospital used computer-generated images of enzyme pantothenate kinase to unlock mysteries of antibiotic resistance and rare brain degeneration. The study found that despite differences in enzyme structure, types II and III can perform the same job as type I, leading to antibiotic resistance.
Researchers are using motion capture cameras and MRI scans to create 3D models of elephant locomotion. The study's goal is to understand how elephants coordinate their limbs and determine if they truly run. This knowledge can improve animal welfare, inform human biomechanics, and aid in the design of walking robots.
A Rutgers research team has been awarded a three-year, $599,436 National Science Foundation grant to collaborate with the Port Authority of New York and New Jersey on improving port competitiveness. The project aims to develop tools for analytical group decision-making and improve security at the nation's ports.
Researchers have found evidence of a binary system in the Quintuplet cluster, where two massive stars are orbiting each other. The discovery of 'pinwheel-shaped' dust spirals around these stars provides further proof of their dual nature and corrects previous estimates of their sizes.
Researchers at NIST determined the three-dimensional shape of class IV adenylyl cyclase, an enzyme found in plague bacteria Yersinia pestis. The unusual configuration may play a role in disrupting cell processes in infected hosts, highlighting the importance of molecular data for developing defenses against plague and other pathogens.
Researchers have solved the mystery of Quintuplet stars by identifying them as young massive binary stars producing large amounts of dust. The study captures the stars just before disintegrating in supernovae explosions, revealing a unique pinwheel nebulae around each star.
Astronomers use Hubble Space Telescope to image two mysterious star types, including tiny, slow-burning stars and ancient, giant white dwarfs. The research pushes limits of observatory's capabilities, gathering data that will help refine theories about low-mass stars and the universe's age.
Artificial muscles can create a full range of colors by adjusting the diffraction grating, overcoming limitations of existing displays. The technology uses white LED lights and could lead to consumer products in under eight years.
A new study by UCLA researchers analyzed clots removed from the brain blood vessels of 25 stroke victims, revealing that they are composed of similar components. The analysis showed that red blood-cell accumulations often accumulated on clots after impaction in the brain artery, contradicting previous assumptions.
