Artificial spleen to treat bloodstream infections: Sepsis therapeutic device under development Posted: 30 Mar 2013 10:05 AM PDT Scientists are developing blood-cleansing technology. The device will be used to treat bloodstream infections that are the leading cause of death in critically ill patients and soldiers injured in combat. To rapidly cleanse the blood of pathogens, the patient's blood is mixed with magnetic nanobeads coated with a genetically engineered version of a human blood 'opsonin' protein that binds to a wide variety of bacteria, fungi, viruses, parasites, and toxins.

Low-power use for mobile devices: 60 GHz radio frequency chip Posted: 29 Mar 2013 01:12 PM PDT Scientists recently developed a low-power version of the 60 GHz radio frequency integrated circuit (RFIC). The research team said that their RFIC draws as little as 67 mW of power in the 60 GHz frequency band, consuming 31mW to send and 36mW to receive large volumes of data.

Inorganic materials display massive and instantaneous swelling and shrinkage Posted: 29 Mar 2013 09:41 AM PDT The first observation of massive swelling and shrinkage of inorganic layered materials like a biological cell provides insights into the production of two-dimensional crystals.

Everything you know about osmosis is (probably) wrong Posted: 28 Mar 2013 12:25 PM PDT Even though the concept is important to plant and human physiology, osmosis is understood in biology and chemistry in simple -- and often incorrect -- way.
