There’s not much good that can be said about asthma, a breathing disease in which the airways become narrowed and inflamed. But there’s this: People with asthma seem to be less likely to develop brain tumors than others. And now, researchers at Washington University School of Medicine in St. LouisContinuar Leyendo
Mutations of a gene that regulates formation of blood vessels in the brain of vertebrates can lead to potentially deadly aneurysms in adults, Yale School of Medicine researchers report in the December issue of Nature Medicine. New Haven, Dec 09, 2021.- Saccular brain aneurysms affect nearly 3% of the humanContinuar Leyendo
Researchers examined autopsy tissue samples of hearts from patients who died early in the COVID-19 pandemic. Frequent and extensive blood clots (thromboses) within heart vessels were found as anticipated, but the type of changes in the endothelial cells lining the heart that are typically observed in thromboses were absent. Instead,Continuar Leyendo
The tiny male golden orb-weaving spider faces a considerable challenge when searching for a mate. He is a fraction of the size of the massive female, but must carefully enter her web and approach her without being noticed, because the cannibalistic female will kill and eat him if he makesContinuar Leyendo
A Canadian-German research team have documented a new type of earthquake in an injection environment in British Columbia, Canada. Unlike conventional earthquakes of the same magnitude, they are slower and last longer. The events are a new type of induced earthquake that have been triggered by hydraulic fracturing, a methodContinuar Leyendo
By performing a series of real and ‘fake’ flybys, ESA’s Mars Express has revealed how Mars’ largest moon, Phobos, interacts with the solar wind of charged particles thrown out by the Sun – and spotted an elusive process that has only been seen at Phobos once before. París, The solarContinuar Leyendo
A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian researchers. The results suggest that countering the activity of these cellsContinuar Leyendo
Which diet is better: moderately reduce meat consumption and eat more fruit, vegetables and wholegrain products, as recommended by the German Nutrition Society? Follow Germany’s southern neighbors’ example and eat more fish and seafood? Or even switch completely to a vegan diet? A new study by the University of BonnContinuar Leyendo
The Arctic Ocean has been getting warmer since the beginning of the 20th century — decades earlier than records suggest — due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean. Cambrigde, Nov 29, 2021.- An international group of researchers reconstructed the recent history of oceanContinuar Leyendo
Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality. Espoo,Continuar Leyendo
