Surprisingly high fraction of dead galaxies found in ancient galactic city Posted: 09 Feb 2022 12:49 PM PST Astronomers have discovered an unusual massive cluster of young galaxies forming in the early universe. The newly discovered growing galactic metropolis, named MAGAZ3NE J095924+022537, is a newborn galaxy cluster, or protocluster, consisting of at least 38 member galaxies, and is about 11.8 billion light-years away from Earth.

New soft robot material to morph from ground to air vehicle using liquid metal Posted: 09 Feb 2022 12:48 PM PST Researchers have developed a new approach for shape changing at the material level. They use rubber, metal, and temperature to morph materials and fix them into place with no motors or pulleys.

Hungry for love: Gut molecule discovered that flips the feeding-to-mating switch Posted: 09 Feb 2022 08:22 AM PST Scientists have identified a molecule released from the gut after a protein-rich meal that switches the focus of fruit flies from eating to courtship. The discovery of Dh31, a type of chemical messenger, opens the door to unexplored areas of gut-to-brain communication.

In a first for 'sonogenetics,' researchers control mammalian cells with sound Posted: 09 Feb 2022 06:34 AM PST Scientists have engineered mammalian cells to be activated using ultrasound. The method paves the way toward non-invasive versions of deep brain stimulation, pacemakers and insulin pumps.

A century later, researchers describe second opabiniid ever discovered Posted: 08 Feb 2022 04:17 PM PST An international team of researchers confirm that a specimen previously considered a radiodont is in fact an opabiniid. The new study used novel and robust phylogenetic methods to confirm Utaurora comosa as only the second opabiniid ever discovered and the first in over a century.

Fecal implants drive behavioral and cognitive changes in Alzheimer’s model Posted: 08 Feb 2022 09:44 AM PST New research in mice for the first time draws a definitive causal connection between changes in the gut microbiome to behavioral and cognitive changes in an animal model of Alzheimer's disease.

Researchers use tiny magnetic swirls to generate true random numbers Posted: 07 Feb 2022 09:48 AM PST Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing.

Engineers develop surgical 'duct tape' as an alternative to sutures Posted: 02 Feb 2022 11:30 AM PST Engineers have developed a kind of surgical 'duct tape.' The strong, flexible, and biocompatible sticky patch can be applied to biological tissues and organs to help seal tears and wounds.
