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 Extended habitability of exoplanets due to subglacial water
(via sciencedaily.com) Original source New research promises to redefine our comprehension of habitable exoplanets. A recent study introduces the concept of subglacial liquid water as a pivotal element in broadening the boundaries of the conventional Habitable Zone.
Published Exploring the origin of nucleosynthetic isotope variations in Ryugu samples
(via sciencedaily.com) Original source The observed variations in chromium (Cr) isotope ratios in the Ryugu asteroid samples collected by Hayabusa2 likely resulted from elemental redistribution of slightly soluble Cr by water within the parent body, reveals a multinational study. The results provide useful insights for expanding our understanding of the origin and evolution of materials in our solar system.
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 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 '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.
Published The remains of an ancient planet lie deep within Earth
(via sciencedaily.com) Original source The remnants of an ancient planet that collided with Earth to form the Moon lie deep within the earth, according to a new model.
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 To advance space colonization, new research explores 3D printing in microgravity
(via sciencedaily.com) Original source Research into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars.
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.
