Technology could help prevent life-threatening infections in patients receiving chemotherapy.

The longevity and health improvements seen in animals on sulfur amino acid-restricted diets could translate to people, according to Penn State College of Medicine researchers who recently conducted a review of published studies. More research is needed to confirm the benefits in people, the scientists said.

Cells with stem-cell characteristics appear to be especially important in the formation and metastasis of tumors. Scientists have now developed a universal fluorescent probe for these “cancer stem cells”. As reported in the journal Angewandte Chemie, this dye also selectively kills off the cells.

Doctors have been using radiation to treat cancer for more than a hundred years, but it’s always been a delicate art to direct treatment while avoiding healthy tissue.

The lack of anti-inflammatory molecules in the brain and other problems with the immune system can impair working memory and ability to learn, say Russian scientists published an article in the journal Neuroreport.

Russian biologists and physicists have created a unique nanoparticle that allows to print three-dimensional structures of arbitrary shape and of any size in one sitting using a conventional infrared laser.

Cancer research that once involved years of painstaking work can now happen in months with a novel technique for systematically studying cancer-related genes. The results reveal how combinations of mutations influence tumor growth.

Scientists of the Center for composite materials nust «MISIS» developed a material for bone implants, with the possibility of self-healing cracks. In was based on a polymer with a shape memory which recovers its structure with local heating.
