Webb demonstrates its spectroscopic power with the first unequivocal detection of carbon dioxide in a planetary atmosphere outside the Solar System. París, August 25, 2022.- The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like starContinuar Leyendo
A new map of Mars is changing the way we think about the planet’s watery past, and showing where we should land in the future. París, August 22, 2022.- The map shows mineral deposits across the planet and has been painstakingly created over the last decade using data from ESA’sContinuar Leyendo
As mice navigate different rooms in virtual reality, the prefrontal neurons (top) communicate with those in the hippocampus (bottom) to conjure associated memories. New York, August 21, 2022.- An unforgettable time at a restaurant is not just about the food. The odors, the decor, the sound of the band playing,Continuar Leyendo
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
