Extensively used grassland is host to a high degree of biodiversity, and performs an important climate protection function as a carbon sink and also serves for fodder and food production. However, these ecosystem services are jeopardised if productivity on these lands is maximised and their use therefore intensified. Until now,Continuar Leyendo
Astronomers estimate that 100 million black holes roam among the stars in our Milky Way galaxy, but they have never conclusively identified an isolated black hole. Following six years of meticulous observations, the NASA/ESA Hubble Space Telescope has, for the first time ever, provided direct evidence for a lone blackContinuar Leyendo
Researchers at Massachusetts General Hospital (MGH) have discovered that the interferon gamma receptor (IFNgR) signaling pathway is critical for susceptibility of glioblastoma tumors to killing by CAR T-cell immunotherapy. The same phenomenon was observed in other solid tumors. This discovery may partly explain why liquid and solid tumors respond veryContinuar Leyendo
ESA’s Comet Interceptor mission to visit a pristine comet or other interstellar object just starting its journey into the inner Solar System has been ‘adopted’ this week; the study phase is complete and, following selection of the spacecraft prime contractor, work will soon begin to build the mission. París, JuneContinuar Leyendo
A multi-center study of more than 3,000 people with high blood pressure and brain aneurysms found that the use of RAAS inhibitors, a class of blood pressure lowering medications, reduced the risk of an aneurysm rupture by 18%, according to new research published today in Hypertension, a peer-reviewed journal ofContinuar Leyendo
In the fall of 2017, geology professor Patricia Gregg and her team had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. One of the scientists onContinuar Leyendo
Superconductors are materials with no electrical resistance whatsoever, commonly requiring extremely low temperatures. They are used in a wide range of domains, from medical applications to a central role in quantum computers. Superconductivity is caused by specially linked pairs of electrons known as Cooper pairs. So far, the occurrence ofContinuar Leyendo
Two separate findings by a University of Houston nationally recognized expert in systemic lupus erythematosus (SLE or lupus), a chronic autoimmune disease that affects multiple organs including the kidneys, skin, joints and heart, are being reported in scientific and medical journals. Houston, June 03, 2022.- Chandra Mohan, M.D., Ph.D., HughContinuar Leyendo
Genetically engineered immune cells successfully target the specific cancer cells that may be responsible for relapse of acute myeloid leukemia (AML), a type of blood cancer, and proved effective in animal models of the disease, according to a preclinical study by investigators at Weill Cornell Medicine. The new cell therapy,Continuar Leyendo
Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations from the Gemini North telescope, the NASA Infrared Telescope Facility, and the Hubble Space Telescope, researchers have developed a single atmospheric model that matches observations of both planets. The model reveals that excess hazeContinuar Leyendo
