Published Why insects navigate more efficiently than robots



Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published 3D printed nanocellulose upscaled for green architectural applications



For the first time, a hydrogel material made of nanocellulose and algae has been tested as an alternative, greener architectural material. The study shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods.
Published A long, long time ago in a galaxy not so far away



Employing massive data sets collected through NASA's James Webb Space Telescope, astronomers are unearthing clues to conditions existing in the early universe. The team has catalogued the ages of stars in the Wolf--Lundmark--Melotte (WLM) galaxy, constructing the most detailed picture of it yet, according to the researchers. WLM, a neighbor of the Milky Way, is an active center of star formation that includes ancient stars formed 13 billion years ago.
Published GPT-3 transforms chemical research



Scientists demonstrate how GPT-3 can transform chemical analysis, making it faster and more user-friendly.
Published Which came first: Black holes or galaxies?



Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles



Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Gas on the run -- ALMA spots the shadow of a molecular outflow from a quasar when the Universe was less than one billion years old



Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old.
Published Bright galaxies put dark matter to the test



The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars. But astrophysicists now show that after the Big Bang, hydrogen and helium gas bounced at supersonic speeds off dense, slowly moving clumps of cold dark matter. When the gas fell back in millennia later, stars formed all at once, creating small, exceptionally bright galaxies. If models of cold dark matter are correct, the James Webb Space Telescope should be able to find patches of bright galaxies in the early universe, potentially offering the first effective test for theories about dark matter. If it doesn't, scientists have to go back to the drawing board with dark matter.
Published Engineers unveil new patch that can help people control robotic exoskeletons



A new patch uses tiny needles to measure electrical signals in the human body with incredible accuracy, even when these devices are stretched or twisted.
Published Artificial muscles -- lighter, safer, more robust



Researchers have developed artificial muscles that are lighter, safer and more robust than their predecessors. The newly developed actuators have a novel type of shell structure and use a high-permittivity ferroelectric material that can store relatively large amounts of electrical energy. They therefore work with relatively low electrical voltage, are waterproof, more robust and safer to touch.
Published Sweat-resistant wearable robot sensor



A joint research team has developed a stretchable and adhesive microneedle sensor that can be attached to the skin and stably measure high-quality electrophysiological signals for a long period of time.
Published Researchers propose AI-guided system for robotic inspection of buildings, roads and bridges



Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.
Published Robot trained to read braille at twice the speed of humans



Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers.
Published Utilizing active microparticles for artificial intelligence



Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.
Published Scientists design a two-legged robot powered by muscle tissue



Compared to robots, human bodies are flexible, capable of fine movements, and can convert energy efficiently into movement. Drawing inspiration from human gait, researchers from Japan crafted a two-legged biohybrid robot by combining muscle tissues and artificial materials. This method allows the robot to walk and pivot.
Published Faint features in galaxy NGC 5728 revealed



A new study describes the best method to improve images obtained by the James Webb Science Telescope (JWST) using a mathematical approach called deconvolution.
Published Autonomous synthesis robot uses AI to speed up chemical discovery



Chemists have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed 'RoboChem', the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate chemical discovery of molecules for pharmaceutical and many other applications.
Published Lightest black hole or heaviest neutron star? MeerKAT uncovers a mysterious object in Milky Way



An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
Published Mini-robots modeled on insects may be smallest, lightest, fastest ever developed



Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.
Published Astronomers detect oldest black hole ever observed



Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
