Genetically engineering NK cells can target and kill glioblastoma stem cells

Preclinical research from The University of Texas MD Anderson Cancer Center finds that although glioblastoma stem cells (GSCs) can be targeted by natural killer (NK) cells, they are able to evade immune attack by releasing the TFG-β signaling protein, which blocks NK cell activity.

New packaging film can keep strawberries fresh for up to 12 days

Québec produces more strawberries than any other Canadian province. Strawberries are delicate and difficult to keep fresh. In response to this challenge, Monique Lacroix, a professor at at the Institut national de la recherche scientifique (INRS), and her team have developed a packaging film that can keep strawberries fresh for up to 12 days.

Study provides new insights into the invariant rate of aging hypothesis

A study led by Fernando Colchero, University of Southern Denmark and Susan Alberts, Duke University, North Carolina, that included researchers from 42 institutions across 14 countries, provides new insights into the aging theory "the invariant rate of aging hypothesis", which states that every species has a relatively fixed rate of aging.
