“#Antibacterial activewear? The claim is just as absurd as it sounds” Credit: Shutterstock Lorna Jane recently launched an “antiviral” line of its activewear, called “LJ Shield,” generating significant backlash from medical professionals. The popular activewear brand has now pedaled back and removed any mention of LJ Shield being antiviral from its marketing. But it still…
“#Cancer-causing dust released by earthworks” Credit: New Zealand Medical Journal Tiny, needle-like fibers that can become airborne if bedrock is disturbed during earthworks has the potential to cause asbestos-type disease and should be investigated, scientists say. The fibers come from a mineral called erionite which originates in silica-rich volcanic rock commonly found in many parts…

“#Do the TRAPPIST-1 planets have atmospheres?” Artist’s impression shows several of the planets orbiting the ultra-cool red dwarf star TRAPPIST-1. Credit: ESO/M. Kornmesser In February of 2017, the scientific community rejoiced as NASA announced that a nearby star (TRAPPIST-1) had a system of no less than seven rocky planets. Since that time, astronomers have conducted…
“#Probing the properties of a 2-D fermi gas” Sound propagating in a two-dimensional Fermi gas. The image shows the density of the gas in time, shortly after a sound wave has been excited. Dark red values correspond to a high density, lighter values to a low density. One can see a wave traveling up and…
“#Using neural-network soundscapes to protect natural environments” Credit: CC0 Public Domain A team of researchers from Imperial College London, the University of Sydney and Cornel University has found that it is possible to create a soundscape from noises in the natural environment using machine-learning algorithms. In their paper published in Proceedings of the National Academy…
