Published Robots predict human intention for faster builds
(via sciencedaily.com) Original source Humans have a way of understandings others' goals, desires and beliefs, a crucial skill that allows us to anticipate people's actions. Taking bread out of the toaster? You'll need a plate. Sweeping up leaves? I'll grab the green trash can. This skill, often referred to as 'theory of mind,' comes easily to us as humans, but is still challenging for robots. But, if robots are to become truly collaborative helpers in manufacturing and in everyday life, they need to learn the same abilities. Computer science researchers aim to teach robots how to predict human preferences in assembly tasks, so they can one day help out on everything from building a satellite to setting a table.
Published Do Earth-like exoplanets have magnetic fields? Far-off radio signal is promising sign
(via sciencedaily.com) Original source Earth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly blasted out of the sun. Researchers have now identified a prospective Earth-sized planet in another solar system as a prime candidate for also having a magnetic field -- YZ Ceti b, a rocky planet orbiting a star about 12 light-years away from Earth.
Published New cyber software can verify how much knowledge AI really knows
(via sciencedaily.com) Original source With a growing interest in generative artificial intelligence (AI) systems worldwide, researchers have created software that is able to verify how much information an AI farmed from an organization's digital database.
Published Origami-inspired robots can sense, analyze and act in challenging environments
(via sciencedaily.com) A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.
Published Galaxy clusters yield new evidence for standard model of cosmology
(via sciencedaily.com) Original source A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models.
Published Robotic hand can identify objects with just one grasp
(via sciencedaily.com) Newly created soft-rigid robotic fingers incorporate powerful sensors along their entire length, enabling them to produce a robotic hand that could accurately identify objects after only one grasp.
Published Forgive or forget: What happens when robots lie?
(via sciencedaily.com) Original source Student researchers investigate how intentional robot deception affects trust, examining the effectiveness of apologies after robots lie.
Published Molecules precursors to life discovered in the Perseus Cloud
(via sciencedaily.com) Original source A study has detected the presence of large quantities of complex organic molecules in one of the nearest star forming regions to the solar system.
Published Microrobot technology: Externally connecting in vivo neural networks
(via sciencedaily.com) Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
Published Scientists observe flattest explosion ever seen in space
(via sciencedaily.com) Original source Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Published 'Taffy galaxies' collide, leave behind bridge of star-forming material
(via sciencedaily.com) Original source The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured a dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in the image. A bridge of highly turbulent gas devoid of significant star formation spans the gap between the two galaxies.
Published Astronomers witness the birth of a very distant cluster of galaxies from the early Universe
(via sciencedaily.com) Original source Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.
Published How cosmic winds transform galactic environments
(via sciencedaily.com) Original source Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds -- high-powered streams of charged particles and gases -- can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.
Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions
(via sciencedaily.com) Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published Preschoolers prefer to learn from a competent robot than an incompetent human
(via sciencedaily.com) Researchers found that preschoolers prefer learning from what they perceive as a competent robot over an incompetent human. This study is the first to use both a human speaker and a robot to see if children deem social affiliation and similarity more important than competency when choosing which source to trust and learn from.
Published JWST confirms giant planet atmospheres vary widely
(via sciencedaily.com) Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.
Published Temperature of a rocky exoplanet measured
(via sciencedaily.com) An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Artificial intelligence discovers secret equation for 'weighing' galaxy clusters
(via sciencedaily.com) Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
Published AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
