Published Computer vision technology effective at determining proper mask wearing in a hospital setting, pilot study finds
(via sciencedaily.com) In a survey and study of hospital employee volunteers, researchers found that a low-cost computer vision system was feasible and well received.
Published Without more data, a black hole's origins can be 'spun' in any direction
(via sciencedaily.com) A study finds that, for now, the catalog of known black hole binaries does not reveal anything fundamental about how black holes form. More data will be needed to determine whether the invisible giants arose from a quiet galactic disk or a more dynamic cluster of stars.
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 Meteorites plus gamma rays could have given Earth the building blocks for life
(via sciencedaily.com) Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids -- life's building blocks -- to our planet. Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.
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 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 Characterizing the earliest galaxies in the universe -- only 200 million years after the Big Bang
(via sciencedaily.com) An international team of astrophysicists has managed to statistically characterize the first galaxies in the Universe, which formed only 200 million years after the Big Bang.
Published New analysis approach could help boost sensitivity of large telescopes
(via sciencedaily.com) Researchers detail an analysis method that could improve telescopes at the Simons Observatory by evaluating their performance before installation. This is the first time the optical performance of a telescope has been confirmed prior to its deployment.
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.
Published Rare sighting of luminous jet spewed by supermassive black hole
(via sciencedaily.com) Astronomers discover a bright optical flare caused by a dying star's encounter with a supermassive black hole.
Published Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
(via sciencedaily.com) Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe.
Published Making 'transport' robots smarter
(via sciencedaily.com) Imagine a team of humans and robots working together to process online orders -- real-life workers strategically positioned among their automated coworkers who are moving intelligently back and forth in a warehouse space, picking items for shipping to the customer. This could become a reality sooner than later, thanks to researchers who are working to speed up the online delivery process by developing a software model designed to make 'transport' robots smarter.
Published Non-detection of key signal allows astronomers to determine what the first galaxies were -- and weren't -- like
(via sciencedaily.com) Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.
Published Astrophysicists hunt for second-closest supermassive black hole
(via sciencedaily.com) As massive as the black hole at the center of the Milky Way, the behemoth is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far -- maybe not for long.
Published Astronomers observe intra-group light -- the elusive glow between distant galaxies
(via sciencedaily.com) Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.
Published A simpler path to better computer vision
(via sciencedaily.com) Research finds using a large collection of simple, un-curated synthetic image generation programs to pretrain a computer vision model for image classification yields greater accuracy than employing other pretraining methods that are more costly and time consuming, and less scalable.
Published A far-sighted approach to machine learning
(via sciencedaily.com) A new technique enables artificial intelligence agents to think much farther into the future when considering how their behaviors can influence the behaviors of other AI agents, toward the completion of a task. This approach improves long-term performance of cooperative or competitive AI agents.
Published Quantum algorithms save time in the calculation of electron dynamics
(via sciencedaily.com) Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, quantum computer algorithms can already run on conventional servers that simulate a quantum computer. A team has succeeded in calculating the electron orbitals and their dynamic development using an example of a small molecule after a laser pulse excitation. In principle, the method is also suitable for investigating larger molecules that cannot be calculated using conventional methods.
Published International team observes innermost structure of quasar jet
(via sciencedaily.com) Scientists have observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
