Researchers investigate cell-free DNA as early sepsis marker in foals
It's hard to be a horse. It's especially hard to be a newborn foal, dropped into a world of microbes and bacteria with your sole initial defense against devastating infections being the antibodies you get from your mother's milk, or colostrum. Resear.....»»
Model highlights three roots of online toxicity
In 2022, Professor of Cognitive Neuroscience Dean Mobbs began to investigate the relationship between social media use and mental health and well-being. As his research program ramps up to test brain activity and physiological markers of stress durin.....»»
For metro governments, bigger may not be economically better
When big cities gobble up smaller ones nearby, residents often are told a consolidated government is more efficient, providing improved services and other economic benefits......»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
Watch a star get destroyed by a supermassive black hole in the first simulation of its kind
Giant black holes in the centers of galaxies like our own Milky Way are known to occasionally munch on nearby stars......»»
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequenc.....»»
Breaking down the indestructible: New technologies target PFAS environmental menace
PFAS are synthetic chemicals widely used in products such as non-stick cookware and waterproof clothing due to their water and grease-resistant properties. However, their persistence in the environment has led to widespread contamination and signific.....»»
Exploring bamboo charcoal"s slow-release properties for enhanced anti-acne formulations containing bamboo vinegar
Bamboo vinegar is a concentrated liquid obtained from bamboo under high temperature and anaerobic conditions. It contains more than 200 organic components, including organic acids, phenols, ketones, alcohols, and esters, among which acetic acid is th.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Hubble spots the Tucana Dwarf in the dark
A splatter of stars glows faintly at almost 3 million light-years away in this new image from NASA's Hubble Space Telescope. Known as the Tucana Dwarf for lying in the constellation Tucana, this dwarf galaxy contains a loose bundle of aging stars at.....»»
Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways
Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of t.....»»
An Iceland volcano erupts again but spares the nearby town of Grindavik for now
A volcano in southwestern Iceland erupted Thursday evening for the sixth time since December, spewing red lava through a new fissure on the Reykjanes Peninsula......»»
Novel carbon nanohorn-based treatment enables efficient delivery of drugs in cancer therapy
Cancer remains one of the most challenging diseases to treat due to its complexity and tendency to metastasize (spread into, or invade, nearby tissues or distant places in the body to form new tumors). Traditional therapies, such as chemotherapy and.....»»
World"s first micromachine twists 2D materials at will
Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbe.....»»
Astronomers explore the nature of galaxy NGC 891 with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 891. Results of the observational campaign, published August 15 on the preprint server arXiv, provide more insights int.....»»
Fiery Tesla Semi crash in California draws NTSB probe
The Tesla Semi ran off the road on Interstate 80 near Emigrant Gap, Calif., around 3 a.m. Aug. 19. No one was injured, but the vehicle caught fire and ignited nearby brush, closing the freeway in both directions for several hours......»»
MeerKAT observations detect a mysterious faint radio ring
An international team of astronomers reports a serendipitous discovery of a new radio ring toward the Galactic center. The newfound object is relatively faint and its true nature is yet unknown. The finding was reported in a research paper forthcomin.....»»
Astronomers discover spectacular increase in the deuterium to hydrogen ratio in Venus"s atmosphere
Thanks to observations by the Solar Occultation in the Infrared (SOIR) instrument on the Venus Express space probe of the European Space Agency (ESA), researchers have discovered an unexpected increase in the abundances of two water molecule variants.....»»
"Amazon" algae shed light on what happens to populations when females switch to asexual reproduction
Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilized gametes and thrive without males. In a study published in Nature Ecology & Evolution, they use.....»»
