Published Researchers find gravitational lensing has significant effect on cosmic birefringence
(via sciencedaily.com) Original source Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into account the gravitational lensing effect, reports a new study.
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 Injectable tissue prosthesis to aid in damaged muscle/nerve regeneration
(via sciencedaily.com) Original source Researchers have made significant strides in biomaterial technology and rehabilitation medicine. They've developed a novel approach to healing muscle injury by employing 'injectable tissue prosthesis' in the form of conductive hydrogels and combining it with a robot-assisted rehabilitation system.
Published Giant planets cast a deadly pall
(via sciencedaily.com) Original source Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.
Published The Crab Nebula seen in new light by NASA's Webb
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.
Published How robots can help find the solar energy of the future
(via sciencedaily.com) Original source To quickly and accurately characterize prospective materials for use in solar energy, researchers built an automated system to perform laboratory experiments and used machine learning to help analyze the data they recorded. Their goal is to identify semiconductor materials for use in photovoltaic solar energy, which are highly efficient and have low toxicity.
Published Robot stand-in mimics movements in VR
(via sciencedaily.com) Original source Researchers have developed a souped-up telepresence robot that responds automatically and in real-time to a remote user's movements and gestures made in virtual reality.
Published Energy-saving AI chip
(via sciencedaily.com) Original source A computer scientist has developed an AI-ready architecture that is twice as powerful as comparable in-memory computing approaches. The researcher applies a new computational paradigm using special circuits known as ferroelectric field effect transistors (FeFETs). Within a few years, this could prove useful for generative AI, deep learning algorithms and robotic applications.
Published Engineers develop breakthrough 'robot skin'
(via sciencedaily.com) Original source Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.
Published A new era for accurate, rapid COVID-19 testing
(via sciencedaily.com) Original source Researchers demonstrate a nanopore-based technique that can detect different variants of SARS-CoV-2, the virus that causes COVID-19. The method was very effective in detecting the Omicron variant of the virus in the saliva of people with COVID-19.
Published Uranus aurora discovery offers clues to habitable icy worlds
(via sciencedaily.com) Original source Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Published Venus had Earth-like plate tectonics billions of years ago, study suggests
(via sciencedaily.com) Original source Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.
Published Deep learning speeds up galactic calculations
(via sciencedaily.com) Original source Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of them are notoriously difficult to simulate accurately in reasonably short amounts of time. For the first time, a team of researchers apply deep learning to the problem of supernova simulation. Their approach can speed up the simulation of supernovae, and therefore of galaxy formation and evolution as well. These simulations include the evolution of the chemistry which led to life.
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 First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
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.
