Researchers have developed a new idea for a cloaking technology. A completely opaque material is irradiated from above with a specific wave pattern - with the effect that light waves from the left can now pass through the material without any obstruction.
Scientists observed an unexpected result when combining urine with a newly engineered nano-powder based on aluminum. It instantly releases hydrogen from the urine at much higher rate than with ordinary water.
Researchers were able to aggregate cells that had incorporated magnetic nanoparticles using only magnets and without an external supporting matrix, with the cells then forming a tissue that can be deformed at will.
Scientists have found a way for increasing the effectiveness of drug delivery to certain types of brain tumors, by packing epirubicin, a known antitumor agent, in specially designed polymeric micelles.
