Researchers Develop Test That Can Diagnose Two Cancer Types

A study published in the journal Molecules proposes UV-visible diffuse reflectance spectrophotometry with optic fibers (FORS) as a non-invasive easy and rapid technique for the preliminary identification of precious gemstones.

One of the promising applications of terahertz waves is non-destructive testing. According to research findings, terahertz time-domain attenuated total reflection spectroscopy could be used to non-destructively detect samples packaged in a thin polyethylene bag based on their spectral fingerprints.

Extreme storms, such as tropical cyclones, are responsible for a significant portion of the plastic debris transported from land to sea yet little is known about the storm response of microplastics and other debris in offshore and open waters. To investigate this, we conducted floating plastic surveys in the center of Sagami Bay, Japan approximately 50 km from the coastline, before and after the passage of a typhoon. The concentrations (number of particles/km2) of micro- and mesoplastics were tw...
