Published Trash-sorting robot mimics complex human sense of touch
(via sciencedaily.com) Original source Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.
Published How did a satellite galaxy of the Milky Way come to be?
(via sciencedaily.com) Original source Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.
Published Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments
(via sciencedaily.com) Original source Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who screens them for potentially hazardous compounds.
Published Protocol for creating 'wired miniature brains'
(via sciencedaily.com) Original source Researchers have developed -- and shared -- a process for creating brain cortical organoids -- essentially miniature artificial brains with functioning neural networks.
Published Researchers demonstrate the first chip-based 3D printer
(via sciencedaily.com) Original source Researchers have demonstrated the first chip-based 3D printer, a tiny device that emits reconfigurable beams of visible light into a well of resin that rapidly cures into a solid shape. The advance could enable a 3D printer small enough to fit in the palm of a person's hand.
Published Webb telescope reveals asteroid collision in neighboring star system
(via sciencedaily.com) Original source Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.
Published Researchers create skin-inspired sensory robots to provide medical treatment
(via sciencedaily.com) Original source Scientists have created innovative soft robots equipped with electronic skins and artificial muscles, allowing them to sense their surroundings and adapt their movements in real-time.
Published The solar system may have passed through dense interstellar clouds 2 million years ago, altering Earth's climate
(via sciencedaily.com) Original source Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models.
Published In a significant first, researchers detect water frost on solar system's tallest volcanoes
(via sciencedaily.com) Original source An international team of planetary scientists has detected patches of water frost sitting atop the Tharsis volcanoes on Mars, which are not only the tallest volcanic mountains on the Red Planet but in the entire solar system.
Published Small, cool and sulfurous exoplanet may help write recipe for planetary formation
(via sciencedaily.com) Original source Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our understanding of how planets forms.
Published In new experiment, scientists record Earth's radio waves from the moon
(via sciencedaily.com) Original source Odysseus, a tenacious lander built by the company Intuitive Machines, almost didn't make it to the moon. But an experiment aboard the spacecraft managed to capture an image of Earth as it might look to observers on a planet far from our own.
Published Lake under Mars ice cap unlikely
(via sciencedaily.com) Original source Researchers have provided a simple and comprehensive -- if less dramatic -- explanation for bright radar reflections initially interpreted as liquid water beneath the ice cap on Mars' south pole.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap
(via sciencedaily.com) Original source A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.
Published Exotic black holes could be a byproduct of dark matter
(via sciencedaily.com) Original source In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.
Published People feel more connected to 'tweezer-like' bionic tools that don't resemble human hands
(via sciencedaily.com) Original source Some say the next step in human evolution will be the integration of technology with flesh. Now, researchers have used virtual reality to test whether humans can feel embodiment -- the sense that something is part of one's body -- toward prosthetic 'hands' that resemble a pair of tweezers. They report that participants felt an equal degree of embodiment for the tweezer-hands and were also faster and more accurate in completing motor tasks in virtual reality than when they were equipped with a virtual human hand.
Published Planet-forming disks around very low-mass stars are different
(via sciencedaily.com) Original source Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.
Published Flapping frequency of birds, insects, bats and whales described by universal equation
(via sciencedaily.com) Original source A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, researchers report in a new study.
Published Olivine unlocks the secrets of the Moon's interior
(via sciencedaily.com) Original source New partitioning coefficients of first-transition row elements, Ga and Ge between olivine and silicate melt have been reported. New high-temperature experiments have investigated the effects of oxygen fugacity and iron content on these partition coefficients. This newly compiled dataset offers insights into interpreting trace elements found in olivine phenocrysts within lunar basalts, shedding light on the deep interior composition of the Moon.
Published Scientists detect slowest-spinning radio emitting neutron star ever recorded
(via sciencedaily.com) Original source Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate -- slower than any of the more than 3,000 radio emitting neutron stars measured to date.
