Starry tail tells the tale of dwarf galaxy evolution
A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called 'ultra-diffuse' galaxies are formed. 01/27/2023 01:12 PM
Looking back at the Tonga eruption
A 'back-projection' technique reveals new details of the volcanic eruption in Tonga that literally shook the world. 01/27/2023 01:11 PM
Mercury helps to detail Earth's most massive extinction event
Scientists are working to understand the cause and how the events of the LPME unfolded by focusing on mercury from Siberian volcanoes that ended up in sediments in Australia and South Africa. 01/27/2023 01:11 PM
Meteorites reveal likely origin of Earth's volatile chemicals
By analyzing meteorites, researchers have uncovered the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life. 01/27/2023 01:11 PM
Most U.S. children use potentially toxic makeup products, often during play
Scientists found that most children in the United States use makeup and body products that may contain carcinogens and other toxic chemicals. 01/26/2023 04:19 PM
Quantum physicists make major nanoscopic advance
In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially. 01/26/2023 04:19 PM
New AI tool makes speedy gene-editing possible
An artificial intelligence program may enable the first simple production of customizable proteins called zinc fingers to treat diseases by turning genes on and off. The researchers who designed the tool say it promises to accelerate the development of gene therapies on a large scale. 01/26/2023 12:44 PM
Scientists observe 'quasiparticles' in classical systems
Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems. 01/26/2023 12:44 PM
NASA's Fermi detects first gamma-ray eclipses from 'spider' star systems
Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar -- the superdense, rapidly rotating remains of a star that exploded in a supernova -- that slowly erodes its companion. 01/26/2023 12:44 PM
AI technology generates original proteins from scratch
Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein. 01/26/2023 12:43 PM
Artificial human skin paves the way to new skin cancer therapy
In a new study, researchers have managed to curb skin cancer. The study was conducted on artificial human skin. 01/26/2023 10:02 AM
Webb spies Chariklo ring system with high-precision technique
In an observational feat of high precision, scientists used a new technique with NASA's James Webb Space Telescope to capture the shadows of starlight cast by the thin rings of Chariklo. Chariklo is an icy, small body, but the largest of the known Centaur population, located more than 2 billion miles away beyond the orbit of Saturn. 01/26/2023 10:02 AM
Versatile robo-dog runs through the sandy beach at 3 meters per second
Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary. 01/26/2023 10:01 AM
New shield blocks electromagnetic interference while allowing wireless optical signals
Researchers have demonstrated for the first time a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and efficiently shields electromagnetic interference in the X band portion of the microwave radio region. 01/25/2023 12:15 PM
Body phenotypes say a lot, but not everything, about a person's health
Researchers studying body phenotypes -- the observable characteristics like height, behavior, appearance and more measurables -- found that regardless of the muscle they had, high levels of fat mass in an individual were associated with poorer overall health. 01/25/2023 12:15 PM
Watch this person-shaped robot liquify and escape jail, all with the power of magnets
Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests. 01/25/2023 12:15 PM
Supplementation with amino acid serine eases neuropathy in diabetic mice
The study adds to growing evidence that some often-underappreciated, 'non-essential' amino acids play important roles in the nervous system. The findings may provide a new way to identify people at high risk for peripheral neuropathy, as well as a potential treatment option. 01/25/2023 12:15 PM
Wearable sensor uses ultrasound to provide cardiac imaging on the go
Engineers and physicians have developed a wearable ultrasound device that can assess both the structure and function of the human heart. The portable device, which is roughly the size of a postage stamp, can be worn for up to 24 hours and works even during strenuous exercise. 01/25/2023 12:15 PM
New geosciences study shows Triassic fossils that reveal origins of living amphibians
A team of paleontologists have discovered the first 'unmistakable' Triassic-era caecilian fossil -- the oldest-known caecilian fossils -- thus extending the record of this small, burrowing animal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature. 01/25/2023 12:15 PM
