No more needles for diagnostic tests? Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells — ScienceDaily

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen […]

Physicists recorded the flowing sound of a ‘perfect’ fluid for the first time

For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as permitted by the laws of quantum mechanics, an ascending glissando of the frequencies at which the fluid resonates. This research can help us to understand some of the most extreme conditions in the Universe – […]

A female hunter’s remains hint at more fluid gender roles in the early Americas

A number of researchers have speculated that some ancient societies might have had a more equal division of labor. (Credit: Matthew Verdolivo (UC Davis IET Academic Technology Services)/) Women in early hunter-gatherer groups regularly hunted big game alongside their male peers, indicates a study published on November 4 in the journal Science Advances. Researchers excavated […]
