A beating biorobotic heart aims to better simulate valves      (via sciencedaily.com)     Original source 

Combining a biological heart and a silicone robotic pump, researchers created a biorobotic heart that beats like a real one, with a focus on a valve on the left side of the heart. The heart valve simulator can mimic the structure, function, and motion of a healthy or diseased heart, allowing surgeons and researchers to demonstrate various interventions while collecting real-time data.

NASA's Webb finds signs of possible aurorae on isolated brown dwarf      (via sciencedaily.com)     Original source 

Astronomers have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, W1935, is cold and lacks a host star; therefore, there is no obvious source for the upper atmosphere energy. The team speculates that the methane emission may be due to processes generating aurorae.

'Blob-like' home of farthest-known fast radio burst is collection of seven galaxies      (via sciencedaily.com)     Original source 

In summer 2022, astronomers detected the most powerful and most distant fast radio burst (FRB) ever observed. Now, astronomers have pinpointed the extraordinary object's birthplace -- and it's rather curious, indeed. Using images from NASA's Hubble Space Telescope, the researchers traced the FRB back to not one galaxy but a group of at least seven galaxies.

Towards more accurate 3D object detection for robots and self-driving cars      (via sciencedaily.com)     Original source 

Robots and autonomous vehicles can use 3D point clouds from LiDAR sensors and camera images to perform 3D object detection. However, current techniques that combine both types of data struggle to accurately detect small objects. Now, researchers have developed DPPFA Net, an innovative network that overcomes challenges related to occlusion and noise introduced by adverse weather. Their findings will pave the way for more perceptive and capable autonomous systems.

Final supernova results from Dark Energy Survey offer unique insights into the expansion of the universe      (via sciencedaily.com)     Original source 

In the culmination of a decade's worth of effort, scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.

New soft robots roll like tires, spin like tops and orbit like moons      (via sciencedaily.com)     Original source 

Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.

Three iron rings in a planet-forming disk      (via sciencedaily.com)     Original source 

Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the gaps between the rings. The detailed analysis is consistent with abundant solid iron grains complementing the dust composition. As a result, the disk likely harbors metals and minerals akin to those in the Solar System's terrestrial planets. It offers a glimpse into conditions resembling the early Solar System over four billion years ago during the formation of rocky planets such as Mercury, Venus, and Earth.

Soft robotic, wearable device improves walking for individual with Parkinson's disease      (via sciencedaily.com)     Original source 

Researchers have used a soft, wearable robot to help a person living with Parkinson's walk without freezing. The robotic garment, worn around the hips and thighs, gives a gentle push to the hips as the leg swings, helping the patient achieve a longer stride. The device completely eliminated the participant's freezing while walking indoors, allowing them to walk faster and further than they could without the garment's help.

Hubble sights a galaxy with 'forbidden' light      (via sciencedaily.com)     Original source 

A whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of the most common subclasses of AGN. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby and their central AGN does not outshine its host, while quasars are very distant AGNs with incredible luminosities that outshine their host galaxies.
