            Scientists have identified at least eight strains of coronavirus as the bug wreaks havoc spreading across the globe. More than 2,000 genetic sequences of the virus have been submitted from labs to the open database NextStain, which shows it mutating on maps in realtime, according to the site. Think of the open-source project Nextstrain.org as an outbreak museum. […]

           By the second trimester, long before a baby’s eyes can see images, they can detect light. But the light-sensitive cells in the developing retina — the thin sheet of brain-like tissue at the back of the eye — were thought to be simple on-off switches, presumably there to set up the 24-hour, day-night rhythms parents […]

           Close to 3 million people in the United States develop difficult to treat infections caused by drug-resistant bacteria and fungi each year — and about 35,000 die, according to a new government report. “The modern medicine available to us today may very well be gone tomorrow if we don’t slow the development of antibiotic resistance,” said Robert […]

           Researchers at the University of Copenhagen have found a new survival mechanism for a commonly known type of bacteria. It can send out warning signals and thus make sure that other bacteria escape ‘dangers’ such as antibiotics. The researchers hope that the new knowledge can be utilised to make antibiotic treatment more effective. A bacterial […]
