Social experiment in women"s amateur soccer: Is a foreign name a disadvantage?
To find out if we discriminate against people with foreign-sounding names an experiment with fictional girls who wanted to play soccer yields some answers......»»
A dog"s breed can affect pain sensitivity, but not necessarily the way your vet may think
Dog breeds differ in pain sensitivity, but these differences don't always match up with the beliefs people—including veterinarians—hold about breed-specific pain sensitivity. The results appear in a new study from North Carolina State University.....»»
Novel method for producing thin metasurfaces with a diameter of almost 30 centimeters
Bye-bye lens, hello metasurface. So-called metasurfaces can help to make optical systems thinner in the future, while at the same time increasing their functionality......»»

NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) mission acquired stunning views of Mars in two ultraviolet images taken at different points along our neighboring planet's orbit around the sun......»»
Bridging the gap for precision medicine: Nanofluidic aptamer nanoarray measures individual proteins
In the evolving world of precision medicine, the need for methods that can measure biomolecules with supreme accuracy and specificity is paramount. Recognizing this, Associate Professor Yan Xu of the Graduate School of Engineering at Osaka Metropolit.....»»
Researcher uses hydrostatic pressure to understand RNA dynamics
Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn......»»
"Shoebox" satellites help scientists understand trees and global warming
The early blooms of some of Washington D.C.'s iconic cherry blossoms this year set off a flurry of questions: Were trees communicating sensitivity to climate change?.....»»
1RXS J165424.6-433758 is a polar, new observations find
An international team of astronomers has performed X-ray, ultraviolet, and optical observations of an X-ray source known as 1RXS J165424.6-433758. Results of the observational campaign, published June 8 on the pre-print server arXiv, shed more light.....»»
Researchers report light-controlled transport of biomolecules across the cell membrane
Crossing the membrane is a major challenge on the journey through the cell. Large biomolecules usually benefit from different transport strategies to overcome the lipid bilayer, so the design and synthesis of new carriers is key for the delivery of h.....»»
Breaking barriers: Advancements in meta-holographic display enable ultraviolet domain holograms
The term meta means a concept of transcendence or surpassing, and when applied to materials, metamaterials encompass artificially engineered substances that exhibit properties not naturally found in the environment. Metasurfaces, characterized by the.....»»
New insight into how xeroderma pigmentosum causative gene products ensure the accuracy of DNA repair
Our genomic DNA is continuously damaged by endogenous factors such as reactive oxygen species, and also by environmental factors such as ultraviolet light, radiation, and chemicals. Failure to repair damaged DNA may induce mutations and cell death, e.....»»
Ozone layer recovery delayed, surface UV radiation continues to rise, finds study
According to a new study published in Advances in Atmospheric Sciences, the ozone isn't healing as quickly as expected, leading to higher levels of surface ultraviolet (UV) radiation in recent years......»»
Plants found to leave chemical fingerprints on an ozone-depleting gas
Methyl chloride (CH3Cl) is one of the most common chlorine-based gases in Earth's atmosphere. Along with related chemicals, it depletes the ozone layer, exposing life on the planet to more of the sun's ultraviolet radiation. The sources and processes.....»»
