Most able-bodied people take their ability to perform simple daily tasks for granted — when they reach for a warm mug of coffee, they can feel its weight and temperature and adjust their grip accordingly so that no liquid is spilled. People with full sensory and motor control of theirContinuar Leyendo
Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body’s immunity changes over time.Continuar Leyendo
The human body is constantly exposed to various environmental actors, from viruses to bacteria to fungi, but most of these microbial organisms provoke little or no response from our skin, which is charged with monitoring and protecting from external dangers. San Diego, May 23, 2021.- Until now, researchers weren’t quiteContinuar Leyendo
One trait shared by all humans is that they don’t remember specific life episodes that occurred before the age of 3 or 4. Many scientists have attributed this so-called «infantile amnesia» to a lack of development in the hippocampus, an area of the brain located in the temporal lobe thatContinuar Leyendo
A new software tool developed by Earlham Institute researchers will help bioinformaticians improve the quality and accuracy of their biological data, and avoid mis-assemblies. The fast, lightweight, user-friendly tool visualises genome assemblies and gene alignments from the latest next generation sequencing technologies. Norwich, UK, May 20, 2021.- Called Alvis, theContinuar Leyendo
A new study by a Belgian team using data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) has shown that iron and nickel exist in the atmospheres of comets throughout our Solar System, even those far from the Sun. A separate study by a Polish team, who alsoContinuar Leyendo
The development of dementia, often from Alzheimer’s disease, late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health. Most of these proteins were not knownContinuar Leyendo
Scientists at UCL have identified a new immunotherapy to combat the hepatitis B virus (HBV), the most common cause of liver cancer in the world. London, May 17, 2021.- Each year, globally, chronic HBV causes an estimated 880,000 deaths from liver cirrhosis and hepatocellular carcinoma/liver cancer (HCC). The pioneering studyContinuar Leyendo
B cells are the immune cells responsible for creating antibodies, and most B cells, known as B2 cells, produce antibodies in response to a pathogen or a vaccine, providing defense and immunity against infections. But a small subset of long-lived B cells, known as B1 cells, are quite different fromContinuar Leyendo
Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world’s second-largest ice sheet, as the effects of climate change continue to accelerate.Continuar Leyendo
