When marine heatwaves and ocean acidity extreme events co-occur, it can have severe impacts on marine ecosystems. Researchers at the Oeschger Center for Climate Change Research at the University of Bern have determined for the first time the frequency and drivers of these compound events and have projected them intoContinuar Leyendo
Chicago, August 17, 2022.- A black hole is usually where information goes to disappear — but scientists may have found a trick to use its last moments to tell us about the history of the universe. In a new study, two University of Chicago astrophysicists laid out a method forContinuar Leyendo
In 2019, NASA’s OSIRIS-REx spacecraft sent back images of a geological phenomenon no one had ever seen before: pebbles were flying off the surface of the asteroid Bennu. The asteroid appeared to be shooting off swarms of marble-sized rocks. Scientists had never seen this behavior from an asteroid before, andContinuar Leyendo
Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place. Greenbelt, MD, August 13, 2022.- Fermi has shown that theContinuar Leyendo
Researchers and entrepreneurs have developed an implant made of collagen protein from pig’s skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The study jointly led by researchers atContinuar Leyendo
Alzheimer’s disease can begin almost imperceptibly, often masquerading in the early months or years as forgetfulness that is common in older age. What causes the disease remains largely a mystery. Medford, MA, August 11, 2022.- But researchers at Tufts University and the University of Oxford, using a three-dimensional human tissueContinuar Leyendo
Onna-son, Okinawa, 06 August, 2022.- Kamptozoa and Bryozoa are two phyla of small aquatic invertebrates. They are related to snails and clams (collectively called mollusks), bristleworms, earthworms, and leeches (collectively called annelids), and ribbon worms (nemertea). But their precise position on the tree of life, and how closely related theyContinuar Leyendo
A full-size, US-produced HL-LHC quadrupole magnet based on niobium–tin technology has passed a critical endurance test, another step towards confirming the technology’s viability inside accelerators. Upton, August 06, 2022.- Future accelerator projects, including the high-luminosity upgrade of the Large Hadron Collider, will rely on niobium–tin (Nb3Sn) alloys for their superconductingContinuar Leyendo
París, August 03, 2022.- On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concertedContinuar Leyendo
Webb’s Instruments Reveal New Details About Star Formation and Black Holes. París, August 02, 2022.- The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of aContinuar Leyendo
