Much of US data to catch newest coronavirus variants is several months old

Much of US data to catch newest coronavirus variants is several months old CNN 1/11/2021 © Getty Images As part of the hunt for new coronavirus variants, an international database shows the United States ranks 61st in how quickly virus samples are collected from patients, analyzed and then posted online. Countries with far fewer resources, including Bangladesh, Sri Lanka and Suriname, process samples more quickly than the United States does. It s pathetic, said Dr. Peter Hotez, a virologist at Baylor College of Medicine. The median number of days from the time a sample is collected from a patient s nose until the time its genetic sequence is posted on GISAID, an independent data sharing initiative, is 85 days, according an analysis of GISAID data by the Broad Institute of Harvard and the Massachusetts Institute of Technology.

Wiktor Szymanowicz/NurPhoto/Getty Images The UK government will publish its Covid-19 UK Vaccines Delivery Plan on Monday, with Health Secretary Matt Hancock scheduled to hold a news conference at Downing Street in the afternoon to provide details on the program. “Since the historic day the first vaccine was approved, the NHS (National Health Service) has made fantastic strides in offering the vaccine to as many at risk people as possible and at record pace,” Hancock said.

DNA-editing method shows promise to treat mouse model of aging disease progeria

DNA-editing method shows promise to treat mouse model of aging disease progeria Using a recently developed DNA base-editing technique, researchers correct accelerating aging disorder. Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria,  a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy. The study was published in the journal  Nature, and was a collaboration between the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health; Broad Institute of Harvard and MIT, Boston; and the Vanderbilt University Medical Center, Nashville, Tennessee.

A cause for celebration : New gene editing tool offers promise of treating many genetic diseases

Caught on video, the woman speaks in a coaxing voice as the tiny animal quivers, but stays put.

They all look healthy and active, with sleek, black coats. If she picked them up, she says, they would jump out of her hand.
