'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.

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.

Astronomers detect seismic ripples in ancient galactic disk      (via sciencedaily.com)     Original source 

 A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way.   At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe. The researchers were able to not only capture the motion of the gas around BRI 1335-0417, but also reveal a seismic wave forming -- a first in this type of early galaxy.

Supernova encore: Second lensed supernova in a distant galaxy      (via sciencedaily.com)     Original source 

In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by the powerful gravity of the intervening galaxy cluster. In addition to warping and magnifying the distant galaxy, the gravitational lensing effect caused by MACS J0138 produces five different images of MRG-M0138.
