Published 'Bouncing' comets could deliver building blocks for life to exoplanets
(via sciencedaily.com) Original source How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.
Published Using eclipses to calculate the transparency of Saturn's rings
(via sciencedaily.com) Original source A student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings.
Published Individual back training machine developed
(via sciencedaily.com) Original source 18 percent of reported sick leave relates to musculoskeletal ailments, in particular back-related disorders. The GyroTrainer is an intelligent training device that resembles a balance board. It uses artificial intelligence to adjust the difficulty level to the individual patient's current ability.
Published Galactic 'lightsabers': Answering longstanding questions about jets from black holes
(via sciencedaily.com) Original source The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.
Published Scientists uncover aurora-like radio emission above a sunspot
(via sciencedaily.com) Original source Astronomers have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km above a relatively dark and cold patch on the Sun, known as a sunspot.
Published Second-most distant galaxy discovered using James Webb Space Telescope
(via sciencedaily.com) Original source The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope.
Published Milky Way-like galaxy found in the early universe
(via sciencedaily.com) Original source Astronomers have discovered the most distant barred spiral galaxy, similar to the Milky Way, that has been observed to date.
Published Glow in the visible range detected for the first time in the Martian night
(via sciencedaily.com) Original source Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughout the year.
Published Engineers are on a failure-finding mission
(via sciencedaily.com) Original source Engineers developed a technique to quickly identify a range of potential failures in a system before they are deployed in the real world.
Published How human faces can teach androids to smile
(via sciencedaily.com) Original source A research team used 125 physical markers to understand the detailed mechanics of 44 different human facial motions. The aim was to better understand how to convey emotions with artificial faces. Beyond helping with the design of robots and androids, this research can also benefit computer graphics, facial recognition, and medical diagnoses.
Published Scientists find 14 new transient objects in space by peering through the 'Christmas Tree Galaxy Cluster'
(via sciencedaily.com) Original source Scientists have discovered 14 new transient objects during their time-lapse study of galaxy cluster MACS0416 -- located about 4.3 billion light years from Earth -- which they've dubbed as the 'Christmas Tree Galaxy Cluster.'
Published New findings support long-proposed process of planet formation
(via sciencedaily.com) Original source Scientists just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, they confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published Lightening the load: Researchers develop autonomous electrochemistry robot
(via sciencedaily.com) Original source Researchers have developed an automated laboratory robot to run complex electrochemical experiments and analyze data. The Electrolab will be used to explore next-generation energy storage materials and chemical reactions that promote alternative and sustainable energy.
Published 450-million-year-old organism finds new life in Softbotics
(via sciencedaily.com) Original source Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Studies of geologic faulting on icy moons aid exploration of extraterrestrial watery worlds
(via sciencedaily.com) Original source Earth and space scientists document and reveal the mechanisms behind strike-slip faulting on the largest moon of Saturn, Titan, and Jupiter's largest moon, Ganymede.
Published Mystery resolved: Black hole feeding and feedback at the center of an active galaxy
(via sciencedaily.com) Original source Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, with high enough resolution to gain further insights into the gas flows to and from the black hole at its galactic nucleus.
Published Black holes are messy eaters
(via sciencedaily.com) Original source New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.
Published Exploding stars
(via sciencedaily.com) Original source When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.
Published 'Jurassic worlds' might be easier to spot than modern Earth
(via sciencedaily.com) Original source An analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.
