An energy-efficient material for removing salt from seawater has been found by engineers at University of Illinois. The material, a nanometer-thick sheet of molybdenum disulfide (MoS2) riddled with tiny holes called nanopores, is specially designed to let high volumes of water through but keep salt and other contaminates out, a process called desalination. The research… Read more
The surface of a single cell contains hundreds of tiny pores, or ion channels, each of which is a portal for specific ions. Ion channels are typically about 1 nanometer wide; by maintaining the right balance of ions, they keep cells healthy and stable. Now researchers at MIT have created tiny pores in single sheets… Read more
Using technical advances not yet developed when the 2014 Ebola outbreak began, UC San Francisco-led scientists completed a proof-of-principle study on a real-time blood test based on DNA sequencing that can be used to rapidly diagnose Ebola and other acute infections. The researchers said that the test can be used even where lab space and… Read more
Researchers at MIT have developed a new thin-film coating that delivers precisely controlled drug doses to specific targets in the body following implantation, effectively becoming a sort of “micro pharmacy.” The film could ultimately be used in the delivery of drugs for diabetes, epilepsy, cancer, and other diseases. It is one of the first drug-delivery coatings that can be remotely activated by applying a small electric field. The film, which is typically about 150 nanometers, or 150 billionths of a meter thick, can be implanted in the body.
