Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com) Original source Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Plant-based materials give 'life' to tiny soft robots
(via sciencedaily.com) Original source A team of researchers has created smart, advanced materials that will be the building blocks for a future generation of soft medical microrobots. These tiny robots have the potential to conduct medical procedures, such as biopsy, and cell and tissue transport, in a minimally invasive fashion.
Published Astronomers detect most distant fast radio burst to date
(via sciencedaily.com) Original source An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observed; in a tiny fraction of a second it released the equivalent of our Sun's total emission over 30 years.
Published Black holes could come in 'perfect pairs' in an ever expanding Universe
(via sciencedaily.com) Original source Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black hole.
Published Robotic prosthetic ankles improve 'natural' movement, stability
(via sciencedaily.com) Original source Robotic prosthetic ankles that are controlled by nerve impulses allow amputees to move more 'naturally,' improving their stability, according to a new study.
Published Choosing exoskeleton settings like a radio station
(via sciencedaily.com) Original source Taking inspiration from music streaming services, a team of engineers has designed the simplest way for users to program their own exoskeleton assistance settings.
Published Grasping the three-dimensional morphology of kilonovae
(via sciencedaily.com) Original source An advanced new three-dimensional (3D) computer simulation of the light emitted following a merger of two neutron stars has produced a similar sequence of spectroscopic features to an observed kilonova. '
Published Scientists, philosophers identify nature's missing evolutionary law
(via sciencedaily.com) Original source A new article describes 'a missing law of nature,' recognizing for the first time an important norm within the natural world's workings. In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.
Published Forensic evidence can survive underwater for weeks
(via sciencedaily.com) Original source Forensic fibers can survive underwater for much longer than previously thought -- which could help criminal investigators uncover vital evidence. New research has found that fiber evidence can survive on fabrics underwater for several weeks.
Published New cyber algorithm shuts down malicious robotic attack
(via sciencedaily.com) Original source Researchers have designed an algorithm that can intercept a man-in-the-middle (MitM) cyberattack on an unmanned military robot and shut it down in seconds. The algorithm, tested in real time, achieved a 99% success rate.
Published NASA's Webb captures an ethereal view of NGC 346
(via sciencedaily.com) Original source One of the greatest strengths of NASA's James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased here in a new image from Webb's Mid-Infrared Instrument (MIRI), is NGC 346 -- the brightest and largest star-forming region in the Small Magellanic Cloud.
Published 'Starquakes' could explain mystery signals
(via sciencedaily.com) Original source Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes. Previous studies have noted broad similarities between the energy distribution of repeat FRBs, and that of earthquakes and solar flares. However, new research has looked at the time and energy of FRBs and found distinct differences between FRBs and solar flares, but several notable similarities between FRBs and earthquakes. This supports the theory that FRBs are caused by 'starquakes' on the surface of neutron stars. This discovery could help us better understand earthquakes, the behavior of high-density matter and aspects of nuclear physics.
Published Finding explanation for Milky Way's warp
(via sciencedaily.com) Original source Though scientists have long known through observational data that the Milky Way is warped and its edges are flared like a skirt, no one could explain why. Now, astronomers have performed the first calculations that fully explain this phenomenon, with compelling evidence pointing to the Milky Way's envelopment in an off-kilter halo of dark matter.
Published Stellar fountain of youth with turbulent formation history in the center of our galaxy
(via sciencedaily.com) Original source An unexpectedly high number of young stars has been identified in the direct vicinity of a supermassive black hole and water ice has been detected at the center of our galaxy.
Published Unifying matter, energy and consciousness
(via sciencedaily.com) Original source Understanding the interplay between consciousness, energy and matter could bring important insights to our fundamental understanding of reality.
Published Pulsars may make dark matter glow
(via sciencedaily.com) Original source The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may reveal itself in the form of a subtle additional glow coming from pulsating stars.
Published Scientists discover the highest energy gamma-rays ever from a pulsar
(via sciencedaily.com) Original source Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports.
Published Plot thickens in hunt for ninth planet
(via sciencedaily.com) Original source A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.
Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
