Nanoparticles of iron compounds + a colloidal solution of water, oil and a surfactant = Awesome ferrofluid video.

When a magnetic field is applied to the fluid, the particles of iron compound inside align to it creating a fluid solid. Click here for more information.

“The retina is a lush layered field of tissue lining the back of the eye, a complex mix of specialized cells that serve as a transfer station where light signals are absorbed and sent to the brain to be translated into sight.

Researchers from University of Wisconsin, Madison have now created these unique retina cells from lowly skin cells — opening the possibility that patients with damaged or diseased retinas might some day be able to grow themselves a cure from their own skin.”

“Whoever thinks science isn’t fun must have never heard of Legos. The colorful construction toy has been used before as a cellular teaching tool. But these days, even researchers working in the nanoscale world get to play around a little.

Johns Hopkins engineers are now using Lego to visualize what is (or might be) happening on scales much too small to see with the naked eye or even to watch dynamically with a microscope. Specifically, they are building blown-up models of a lab-on-a-chip to watch and test the dynamics at work in those minuscule machines.”

“Since 2006, about 30 percent of the commercial honeybee population has died off due to Colony Collapse Disorder. Though many theories have emerged about the causes of CCD since it first began ravaging honeybee populations, a study released this week has identified the first molecular marker of the disorder.

Researchers from the University of Illinois and the U.S. Department of Agriculture used information compiled through the Honeybee Genome Project to compare gene expressions in healthy bees with CCD-affected bees. They discovered large quantities of fragmented ribosomal RNA in CCD-affected bees. These fragments were found in the healthy bees, too — they are apparently products of the damage repair mechanism in insects in general — but they’re present to a much greater extent in CCD-affected bees.”
