Published Webb Space Telescope reveals previously shrouded newborn stars
(via sciencedaily.com) Astronomers took a 'deep dive' into one of the first images from NASA's James Webb Space Telescope and were rewarded with a surprising discovery: telltale signs of two dozen previously unseen young stars about 7,500 light years from Earth.
Published Marsquake!
(via sciencedaily.com) The quake lasted four hours and identified layering in the crust that could indicate a meteoroid impact. The 4.7 magnitude temblor happened in May 2022 and released five times more energy than any previously recorded quake on Mars. Mapping the seismic activity on Mars will help inform scientists where and how to build structures to ensure the safety of future human explorers.
Published Researchers develop wireless, ultrathin 'Skin VR' to provide a vivid, 'personalized' touch experience in the virtual world
(via sciencedaily.com) Enhancing the virtual experience with the touch sensation has become a hot topic, but today's haptic devices remain typically bulky and tangled with wires. Researchers have now developed an advanced wireless haptic interface system, called WeTac, worn on the hand, which has soft, ultrathin soft features, and collects personalized tactile sensation data to provide a vivid touch experience in the metaverse.
Published New robot does 'the worm' when temperature changes
(via sciencedaily.com) A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings 'a kind of intelligence' to the field of soft robotics.
Published Molecular shape-shifting
(via sciencedaily.com) Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists revealed this mechanism which may be used to actively manipulate molecular organization. A seed of the novel desired configuration is sufficient to trigger reorganization. This principle can be applied on to biological building blocks which are constantly recycled to form new structures in living systems.
Published Model shows how intelligent-like behavior can emerge from non-living agents
(via sciencedaily.com) A new model describes how biological or technical systems form complex structures equipped with signal-processing capabilities that allow the systems to respond to stimulus and perform functional tasks without external guidance.
Published Watching water droplets merge on the International Space Station
(via sciencedaily.com) Researchers design and analyze droplet experiments that were done on the International Space Station. The researchers sent four different surfaces with various roughness properties to the station, where they were mounted to a lab table. Cameras recorded the droplets as they spread and merged. The experimental results confirmed and expanded the parameter space of the Davis-Hocking model, a simple way to simulate droplets.
Published Sound recording made of dust devils (tiny tornadoes of dust, grit) on Mars
(via sciencedaily.com) When the rover Perseverance landed on Mars, it was equipped with the first working microphone on the planet's surface. Scientists have used it to make the first-ever audio recording of an extraterrestrial whirlwind.
Published Bolstering the safety of self-driving cars with a deep learning-based object detection system
(via sciencedaily.com) Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.
Published First ultraviolet imaging of Sun's middle corona
(via sciencedaily.com) Researchers have discovered web-like plasma structures in the Sun's middle corona. The researchers describe their innovative new observation method, imaging the middled corona in ultraviolet (UV) wavelength. The findings could lead to a better understanding of the solar wind's origins and its interactions with the rest of the solar system.
Published Antihelium nuclei as messengers from the depths of the galaxy
(via sciencedaily.com) How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team has now measured the survival rate of antihelium nuclei from the depths of the galaxy -- a necessary prerequisite for the indirect search for Dark Matter.
Published Deep-space optical communication demonstration project forges ahead
(via sciencedaily.com) Scientists have demonstrated new laser systems for deep-space optical communication.
Published Soft robot detects damage, heals itself
(via sciencedaily.com) Engineers have created a soft robot capable of detecting when and where it was damaged -- and then healing itself on the spot.
Published NASA missions probe game-changing cosmic explosion
(via sciencedaily.com) On Dec. 11, 2021, astronomers detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray bursts (GRBs), the most powerful events in the universe.
Published Peekaboo! Tiny, hidden galaxy provides a peek into the past
(via sciencedaily.com) Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years across, the tiny galaxy HIPASS J1131-31 has been nicknamed "Peekaboo" because of its emergence in the past 50-100 years from behind the fast-moving star that was obscuring astronomers' ability to detect it.
Published Researchers use ultrasound waves to move objects hands-free
(via sciencedaily.com) Researchers have discovered a new method to move objects using ultrasound waves, opening the door for using contactless manipulation in industries such as robotics and manufacturing.
Published Giant mantle plume reveals Mars is more active than previously thought
(via sciencedaily.com) Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. The discovery reveals that Mars, like Earth and Venus, possesses an active interior, which challenges current views on the evolution of the red planet.
Published Researchers say space atomic clocks could help uncover the nature of dark matter
(via sciencedaily.com) Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark matter.
Published Checking blood pressure in a heartbeat, using artificial intelligence and a camera
(via sciencedaily.com) Original source Engineers have designed a system to remotely measure blood pressure by filming a person's forehead and extracting cardiac signals using artificial intelligence algorithms.
Published Pulses driven by artificial intelligence tame quantum systems
(via sciencedaily.com) Original source Machine learning drives self-discovery of pulses that stabilize quantum systems in the face of environmental noise.
