CEP: News Update


Researchers at Chalmers Univ. of Technology in Göteborg, Sweden, have developed a new method to provide structural support to canvas using nanomaterials. The method, called consolidation, treats the degraded canvas fibers with a combination of polyelectrolyte-treated silica nanoparticles (SNPs) and cellulose nanofibrils (CNFs).

Just as it is important to brush your teeth every day, it is also important to clean orthodontic retainers to keep your breath smelling fresh. However, the thermoplastic polymers that are used to fabricate retainers, aligners, and other clear overlay appliances (COAs) accumulate bacteria, making it hard to keep them hygienic. A team from South Korea has developed a polysaccharide-based antibacterial coating that helps COAs resist bacteria growth and increases their durability.

Researchers based in China have developed small circular single-stranded DNA (CSSD) that can reduce tumor malignancy and restore the body’s defenses against cancer.

Researchers from the Univ. of Queensland, along with colleagues in Brazil, have developed an effective, reagent-free way to identify mosquitos with Zika virus using near-infrared spectroscopy (NIRS). The technique can distinguish between infected and noninfected mosquitos with accuracies of 94–99% seven days after infection.

According to the National Cancer Institute, breast cancer is the most common cancer among women, with more than 250,000 new cases expected in the U.S. in 2018. A mammogram is a screening method that uses low-energy X-rays to detect breast cancer. However, mammograms are uncomfortable for patients and do not always produce accurate results. Although they can uncover suspicious lumps or abnormalities in breast tissue, mammograms cannot distinguish between cancerous and benign growths, and they are not accurate when imaging dense breast tissue.

Happy hour just got happier, thanks to a new technique developed by scientists from the Univ. of Adelaide that removes bad odors from wines.
