Understanding SARS-CoV-2 antibody binding

Researchers mapped where various antibodies bind to the SARS-CoV-2 spike protein. The results could lead to more effective COVID-19 therapies.

The genetic effects of Chernobyl radiation exposure

At a Glance Researchers found no evidence that radiation exposure from the Chernobyl accident caused genetic changes that were passed on to children. Scientists also found that thyroid cancers arising after radiation exposure were more likely to have certain types of DNA damage. The results further our understanding of the genetic effects of radiation exposure. Researchers used DNA sequencing technology to explore the effects of radiation from the Chernobyl nuclear disaster. National Cancer Institute | iStock In April 1986, an accidental reactor explosion at the Chernobyl nuclear power plant in present-day Ukraine exposed millions of people in the surrounding area to radioactive contaminants. “Cleanup” workers were also exposed. Such radiation is known to cause changes, or mutations, in DNA.

"Sweat sticker" for diagnosing cystic fibrosis | National Institutes of Health (NIH)

At a Glance Researchers created a “sweat sticker” for measuring chloride concentrations in sweat, a sign of cystic fibrosis. The sticker could allow earlier and more reliable diagnoses. A healthy infant modeling a device developed to diagnose cystic fibrosis by measuring chloride concentrations in sweat.Northwestern University Cystic fibrosis (CF), a life-shortening genetic disorder, affects about 30,000 people nationwide. People with CF have a faulty protein that affects the glands that make mucus and sweat, causing problems in the lungs and other organs. Maintaining quality of life and extending life expectancy depends on early diagnosis. One of the characteristic features of CF is excessive chloride in sweat. Measuring sweat chloride remains the gold standard for CF diagnosis. Typically, this involves collecting sweat in a device strapped to the wrist. The collected sweat is then transferred to a separate device for chloride measurement. But this approach often prod
