This new nanotech could help clean up Earth’s microplastics – PBS NewsHour

Scientists have designed reusable nano-sized reactors — called nanocoils — that can trigger microplastic breakdown. The work could someday be applied to wastewater, cutting off the flow of microplastics before they are flushed into the environment. Photo by REUTERS/Eric Gaillard

CRISPR gene-editing ‘eliminates’ HIV in some mice. What does it mean for humans?- PBS NewsHour

For the millions of people infected with HIV, the best way to manage the disease is antiretroviral therapy, which can lower the amount of HIV replicating in the body to undetectable levels. But antiretroviral therapy (ART) can only manage HIV, never eliminate it. A new study of mice charts a preliminary path to eliminating this medication dependency, through gene editing with CRISPR.

Nanomaterials that inhibit bacterial growth – ScIU

Examples of objects on a size scale from an x-ray wavelength at 10 picometers (1 × 10^-11 meters) up to the statue of liberty at 100 meters. Each increment on the scale line increases by an order of magnitude, or 10 times. Other images include a water molecule (1 × 10^-10 meters), a carbon nanotube (1 × 10^-9 meters), an antibody (1 × 10^-8 meters), a virus like particle (1 × 10^-7 meters), a bacterium (1 × 10^-6 meters), a strand of hair (1 × 10^-5 meters), a single pixel (1 × 10^-4 meters), an ant (1 × 10^-3 meters), a penny (1 × 10^-2 meters), an adorable black labrador retriever (1 meter), and the width of an end zone ( shorter length) of a football field (1 ×10^1 meters).
