Published AI's memory-forming mechanism found to be strikingly similar to that of the brain
(via sciencedaily.com)
Original source 
An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published Scientists measure the distance to stars by their music
(via sciencedaily.com)
Original source 
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe.
Published New red galaxies turn out to be already known blue galaxies
(via sciencedaily.com)
Original source 
Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data.
Published Astronomers discover first population of binary stripped stars
(via sciencedaily.com)
Original source 
Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers.
Published Reaching for the (invisible) stars
(via sciencedaily.com)
Original source 
Supernovae -- stellar explosions as bright as an entire galaxy -- have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, scientists may have found the missing precursor star population.
Published Unexpected chemistry reveals cosmic star factories' secrets
(via sciencedaily.com)
Original source 
Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into individual colors, the scientists were amazed to discover light from many different molecules -- more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com)
Original source 
Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Engineers design a robotic replica of the heart's right chamber
(via sciencedaily.com)
Original source 
Engineers developed a robotic replica of the heart's right ventricle, which mimics the beating and blood-pumping action of live hearts. The device could be used for studying right ventricle disorders and testing devices and therapies aimed at treating those disorders.
Published Stellar winds regulate growth of galaxies
(via sciencedaily.com)
Original source 
Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already been observed in the local universe, an international research team has just revealed the existence of the phenomenon in galaxies which are more than 7 billion years old and actively forming stars, the category to which most galaxies belong. The team's findings thus show this is a universal process.
Published Artificial intelligence makes gripping more intuitive
(via sciencedaily.com)
Original source 
Artificial hands can be operated via app or with sensors placed in the muscles of the forearm. New research shows: a better understanding of muscle activity patterns in the forearm supports a more intuitive and natural control of artificial limbs. This requires a network of 128 sensors and artificial intelligence based techniques.
Published Exposure to soft robots decreases human fears about working with them
(via sciencedaily.com)
Original source 
Seeing robots made with soft, flexible parts in action appears to lower people's anxiety about working with them or even being replaced by them. A study found that watching videos of a soft robot working with a person at picking and placing tasks lowered the viewers' safety concerns and feelings of job insecurity. This was true even when the soft robot was shown working in close proximity to the person. This finding shows soft robots hold a potential psychological advantage over rigid robots made of metal or other hard materials.
Published Astronomers determine the age of three mysterious baby stars at the heart of the Milky Way
(via sciencedaily.com)
Original source 
Through analysis of high-resolution data from a ten-meter telescope in Hawaii, researchers have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars proved to be unusually young with a puzzling chemical composition that surprised the researchers.
Published Underwater vehicle AI model could be used in other adaptive control systems
(via sciencedaily.com)
Original source 
Unmanned Underwater Vehicles (UUVs) are used around the world to conduct difficult environmental, remote, oceanic, defense and rescue missions in often unpredictable and harsh conditions. A new study has now used a novel bio-inspired computing artificial intelligence solution to improve the potential of UUVs and other adaptive control systems to operate more reliability in rough seas and other unpredictable conditions.
Published Snail-inspired robot could scoop ocean microplastics
(via sciencedaily.com)
Original source 
Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
Published A color-based sensor to emulate skin's sensitivity
(via sciencedaily.com)
Original source 
In a step toward more autonomous soft robots and wearable technologies, researchers have created a device that uses color to simultaneously sense multiple mechanical and temperature stimuli.
Published Ghostlike dusty galaxy reappears in James Webb Space Telescope image
(via sciencedaily.com)
Original source 
Astronomers studying images from the James Webb Space Telescope have identified an object as a 'dusty star-forming galaxy' from nearly 1 billion years after the Big Bang. They have also discovered more than a dozen additional candidates, suggesting these galaxies might be three to 10 times as common as expected. If that conclusion is confirmed, it suggests the early universe was much dustier than previously thought.
Published A new possible explanation for the Hubble tension
(via sciencedaily.com)
Original source 
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values. This so-called 'Hubble tension' poses a puzzle for cosmologists. Researchers are now proposing a new solution: Using an alternative theory of gravity, the discrepancy in the measured values can be easily explained -- the Hubble tension disappears.
Published Researchers develop novel deep learning-based detection system for autonomous vehicles
(via sciencedaily.com)
Original source 
Autonomous vehicles require object detection systems to navigate traffic and avoid obstacles on the road. However, current detection methods often suffer from diminished detection capabilities due to bad weather, unstructured roads, or occlusion. Now, a team of researchers has developed a novel Internet-of-Things-enabled deep learning-based end-to-end 3D object detection system with improved detection capabilities even under unfavorable conditions. This study marks a significant step in autonomous vehicle object detection technology.
Published Blasts to clear World War II munitions could contaminate the ocean
(via sciencedaily.com)
Original source 
World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.
