Washington, May 09, 2022.- The James Webb Space Telescope is aligned across all four of its science instruments, as seen in a previous engineering image showing the observatory’s full field of view. Now, we take a closer look at that same image, focusing on Webb’s coldest instrument: the Mid-Infrared Instrument,Continuar Leyendo
Scar-like cells that make up a sizable portion of malignant pancreatic tumors and shield these cancers from immune attack are derived from mesothelial cells that line tissues and organs, a new study led by UT Southwestern researchers suggests. The findings, published in Cancer Cell, could offer a new strategy toContinuar Leyendo
Are astronauts more likely to develop blood clots during space missions due to zero gravity? That’s the question NASA is trying to answer with help from UNC School of Medicine’s Stephan Moll, MD, professor in the UNC Department of Medicine. A new publication in Vascular Medicine shows the results ofContinuar Leyendo
Elevated levels of an enzyme called PHGDH in the blood of older adults could be an early warning sign of Alzheimer’s disease, and a study led by the University of California San Diego provides new evidence to support this claim. In analyzing brain tissue, researchers observed a trend consistent withContinuar Leyendo
Today, ESA and the Zooniverse launch Rosetta Zoo, a citizen science project that invites volunteers to engage in a cosmic game of ‘spot the difference’. By browsing through pictures collected by ESA’s Rosetta mission, you can help scientists figure out how a comet’s surface evolves as it swings around theContinuar Leyendo
When you daydream, or ruminate on something bothersome, or ponder the past, or plan for the future, the part of your brain most engaged is the default mode network, or DMN, which includes part of the prefrontal cortex. Scientists have long hypothesized that changes to DMN dynamics play major rolesContinuar Leyendo
Newcastle University scientists have found new types of plastic loving bacteria that stick to plastic in the deep sea that may enable them to ‘hitchhike’ across the ocean. Newcastle upon Tyne, April 30, 2022.- The team showed for the first time that these deep-sea, plastic loving bacteria make up onlyContinuar Leyendo
Archival observations of 25 hot Jupiters by the NASA/ESA Hubble Space Telescope have been analysed by an international team of astronomers, enabling them to answer five open questions important to our understanding of exoplanet atmospheres. Amongst other findings, the team found that the presence of metal oxides and hydrides inContinuar Leyendo
In a small but multi-institutional study, an artificial intelligence-based system improved providers’ assessments of whether patients with bladder cancer had complete response to chemotherapy before a radical cystectomy (bladder removal surgery). Ann Arbour, April 25, 2022.- Yet the researchers caution that AI isn’t a replacement for human expertise and thatContinuar Leyendo
Physicists at the University of California, Irvine have demonstrated the use of a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope, a technique that can measure the chemical properties of materials at unprecedented time and spatial resolutions. Irvine, April 25, 2022.- This new technique canContinuar Leyendo
