El homólogo terráqueo del vehículo robotizado de la ESA Rosalind Franklin ha logrado perforar y extraer muestras del suelo hasta una profundidad de 1,7 m, un valor mucho mayor del alcanzado hasta la fecha por ningún otro robot sobre la superficie de Marte. París, September 16, 2021.- Esta exitosa recogidaContinuar Leyendo
Transporting a single brick to Mars can cost more than a million British pounds — making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrialContinuar Leyendo
Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines. Melbourne, September 13, 2021.- The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using aContinuar Leyendo
Although metabolic conditions such as obesity and type 2 diabetes have been linked to an increased risk of COVID-19, as well as an increased risk of experiencing serious symptoms once infected, the impact of diet on these risks is unknown. In a recent study led by researchers at Massachusetts GeneralContinuar Leyendo
HIV is a master of evading the immune system, using a variety of methods to prevent the body from being able to find and kill it. The vast majority of people living with HIV require daily medication to suppress the virus and therefore prevent the development of AIDS. Boston, SeptemberContinuar Leyendo
Insulin is a key hormone in energy metabolism and blood sugar regulation. Normal insulin function in the body may be disturbed by e.g. overweight, leading to decreased insulin sensitivity and increased risk of developing type 2 diabetes and cardiovascular diseases. In a Finnish collaborative study of Turku PET Centre andContinuar Leyendo
Climate change is a truth of the 21st century that is difficult to avoid. The burning of fossil fuels in industry, for transport, and other everyday life activities of Homo sapiens has resulted in elevated levels of CO2 in the Earth’s atmosphere. Extreme weather conditions as seen in recent flood,Continuar Leyendo
An avocado a day could help redistribute belly fat in women toward a healthier profile, according to a new study from the University of Illinois Urbana-Champaign and collaborators. Urbana, September 08, 2021.- One hundred and five adults with overweight and obesity participated in a randomized controlled trial that provided oneContinuar Leyendo
COVID-19 patients have differing immune responses that lead to disease outcomes ranging from asymptomatic SARS-CoV-2 infection to death. After examining the blood samples from nearly 200 COVID-19 patients, researchers have uncovered underlying metabolic changes that regulate how immune cells react to the disease. These changes are associated with disease severityContinuar Leyendo
As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are their dark matterContinuar Leyendo
