A degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells has been developed by a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science.

Tiny shells (about 100 nanometers in length, roughly half the size of the smallest bacterium) are composed of a water-soluble polymer that safely delivers a protein complex to the nucleus of cancer cells to induce their death. The shells degrade harmlessly in non-cancerous cells.

The process does not present the risk of genetic mutation posed by gene therapies for cancer, or the risk to healthy cells caused by chemotherapy, which does not effectively discriminate between healthy and cancerous cells, said Yi Tang, a professor of chemical and biomolecular engineering and a member of the California NanoSystems Institute at UCLA.

A South Korean study evaluating the antioxidant and antimicrobial activities of tea extracts found that green tea showed the highest antioxidant activity in most tests and potent antimicrobial activity.

Researchers have now reported that the use of quantum dots - tiny luminescent crystals that can be used to monitor disease at a cellular level - appears to be safe in primates over a one-year period.

Manchester scientists have developed a tiny molecular machine that mirrors the function of the ribosome, which builds the proteins in our body's cells.

The ultimate goal is to synthesize new drug molecules or new types of plastic.

Researchers are working to find ways to strengthen a microscopic cellular defender that has the power to boost cellular health and longevity.

Ray & Terry recommend green tea as a healthy beverage containing calming l-theanine and many useful plant nutrients. 

Green tea has been examined for numerous potential health benefits, including glucose management, cognitive support, immune health, weight management, and cellular function.
