Over the past 34 years, rainfall in Uganda has decreased by about 12 percent even though many of the global climate models predict an increase in rainfall for the area, according to an international team of researchers. Rainfall levels in Uganda impact agriculture, food security, wildlife habitats and regional economics as well as the prevalence of certain diseases.

Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous — their own — immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumors in mice.

Lightning and volcanos both produce glass, and humans have been making glass from silicon dioxide since prehistory. Industrialization brought us boron-based glasses, polymer glasses and metallic glasses, but now an international team of researchers has developed a new family of glass based on metals and organic compounds that stacks up to the original silica in glass-forming ability.
