            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. […]

Q: What can other countries learn from the way China has approached COVID-19? A: Social distancing is the essential strategy for the control of any infectious diseases, especially if they are respiratory infections. First, we used “nonpharmaceutical strategies,” because […]

Five critically ill patients were hospitalized in Shenzhen, China, with serious cases of COVID-19. They received an experimental plasma transfusion and have since recovered to varying degrees, according to new research published 27 March 2020 in the Journal […]

           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 […]

           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 […]

           A single course of antibiotics can change the composition of oral and gut microbiomes for at least a year, according to a modelling study by UCL researchers. Moreover, this change leads to a decrease in the number and types of microbes found in the gut, but an increase in the diversity of the oral microbiome. […]

            In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone’s brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. This breakthrough, which harnesses the power of speech synthesizers and artificial intelligence, could lead to new ways for computers to […]

    1      1Share Researchers of the University of Bern, Switzerland, showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning. Sleeping time […]

           Pain sensation and the emotional experience of pain are not the same, and now, in mice, scientists at Stanford have found the neurons responsible for the latter. Gregory Scherrer and his collaborators have identified in mice an ensemble of cells that seems to specifically function as an on-off switch for pain aversion. Paul Sakuma If […]
