LA JOLLA, CA—Immune system researchers have designed a computational tool to boost pandemic preparedness. Scientists can use this new algorithm to compare data from vastly different experiments and better predict how individuals may respond to disease. “We’re trying to understand how individuals fight off different viruses, but the beauty of our method is you can apply it generally in other biological settings, such as comparisons of different drugs or different cancer cell lines,” says Tal Einav, Ph.D., ...

Bacterial biofilms are clusters of microorganisms that form on wetted surfaces virtually everywhere. They harbor pathogens that compromise water quality, and they can disrupt the operation of many different engineered systems through the corrosion, fouling and clogging of tanks, pipes and valves. In some settings, they could even be deadly. Space suits that enable crew operations outside of the International Space Station use recirculating water to regulate body temperatures in the orbital extremes of full sun (250 F) and full shade (-250 F). But biofilms blooming in those water lines have nearly compromised astronaut safety during ...

AURORA, Colo. (July 25, 2023) – Scientists at the University of Colorado Anschutz Medical Campus have discovered what they believe to be the central mechanism behind cognitive decline associated with normal aging. “The mechanism involves the mis-regulation of a brain protein known as CaMKII which is crucial for memory and learning,” said the study’s co-senior author Ulli Bayer, PhD, professor of pharmacology at the University of Colorado School of Medicine. “This study directly suggests specific pharmacological treatment strategies.” The study was published today in the journal `Science Signaling.’ Researchers using ...
