Researchers create realistic virtual rodent      (via sciencedaily.com)     Original source 

To help probe the mystery of how brains control movement, scientists have created a virtual rat with an artificial brain that can move around just like a real rodent. The researchers found that activations in the virtual control network accurately predicted neural activity measured from the brains of real rats producing the same behaviors.

Trash-sorting robot mimics complex human sense of touch      (via sciencedaily.com)     Original source 

Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.

NASA's Webb opens new window on supernova science      (via sciencedaily.com)     Original source 

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments      (via sciencedaily.com)     Original source 

Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who screens them for potentially hazardous compounds.

Hubble finds surprises around a star that erupted 40 years ago      (via sciencedaily.com)     Original source 

Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst onto the scene as a bright and long-lived nova. A nova is a star that suddenly increases its brightness tremendously and then fades away to its former obscurity, usually in a few months or years.

Galactic bloodlines: Many nearby star clusters originate from only three 'families'      (via sciencedaily.com)     Original source 

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of giant gas structures in galaxies like our Milky Way.

Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap      (via sciencedaily.com)     Original source 

A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.

Planet-forming disks around very low-mass stars are different      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.
