Relaxing Covid-19 restrictions could pave the way for new vaccine-resistant virus mutations, according to researchers at the University of East Anglia and the Earlham Institute. Norlfok, July 28, 2021.- A new article published today warns against relaxing Covid-19 restrictions prematurely. It describes how we are in an ‘arms race’ withContinuar Leyendo
A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus, a deeper structure strongly associated with memory but shrouded in mysteryContinuar Leyendo
París, July 27, 2021.- Jupiter’s moon Ganymede is the largest moon — and the ninth-largest object — in the Solar System. It may hold more water than all of Earth’s oceans, but temperatures there are so cold that water on the surface freezes and the ocean lies roughly 160 kilometresContinuar Leyendo
The rapid spread of the Alpha variant of COVID-19 resulted from biological changes in the virus and was enhanced by large numbers of infected people ‘exporting’ the variant to multiple parts of the UK, in what the researchers call a ‘super-seeding’ event. Oxford, UK, July 26, 2021.- Results of theContinuar Leyendo
Scientists have identified five new plant species in the Bolivian Andes. Exeter, Devon, UK, July 26, 2021.- The species are all part of the genus Jacquemontia, which are twining or trailing plants with pretty blue flowers. With rapid biodiversity loss taking place across South America and worldwide, identifying plant speciesContinuar Leyendo

Birmingham, July 24, 2021.- That route ofContinuar Leyendo
University of Virginia School of Medicine researchers have discovered a previously unknown repair process in the brain that they hope could be harnessed and enhanced to treat seizure-related brain injuries. Charlottesville, VA, July 24, 2021.- Common seizure-preventing drugs do not work for approximately a third of epilepsy patients, so newContinuar Leyendo

For much of human history, animals and plants were perceived to follow a different set of rules than the rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by a non-physical energy or «life force» that allowed them toContinuar Leyendo
A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world. Ithaca, July 23, 2021.- The cutting-edge technologies were developed in theContinuar Leyendo
