Tired of your bulky microscope? Researchers at the California Institute of Technology have developed a super-compact high-resolution microscope, small enough to fit on a finger tip.

This "microscopic microscope" operates without lenses but has the magnifying power of a top-quality optical microscope, can be used in the field to analyze blood samples for malaria or check water supplies for giardia and other pathogens, and can be mass-produced for around $10.

"The whole thing is truly compact--it could be put in a cell phone--and it can use just sunlight for illumination, which makes it very appealing for Third-World applications," says Changhuei Yang, assistant professor of electrical engineering and bioengineering at Caltech, who developed the device, dubbed an optofluidic microscope, along with his colleagues at Caltech.

Penn State researchers have used computed tomography (CT) technology to virtually glue newly-discovered skull fragments of a rare extinct lemur back into its partial skull, which was discovered over a century ago. Alan Walker, Evan Pugh Professor of Anthropology and Biology at Penn State, and Research Associate in Anthropology Timothy Ryan, led the research.

The different fragments of this lemur's skull are separated by thousands of miles, with the partial skull in Vienna and the pieces of frontal bone in the United States. The result of the digital manipulation is a nearly complete skull of Hadropithecus stenognathus, which is one of only two known skulls for this species.

A fish-heavy diet has gotten another endorsement, this one saying that a lifetime of eating tuna, sardines, salmon and other fish appears to protect Japanese men against clogged arteries, despite other cardiovascular risk factors.

The research, published in the August 5, 2008, issue of Journal of the American College of Cardiology (JACC), suggests that the protection comes from omega-3 fatty acids found in abundance in oily fish. In the first international study of its kind, researchers found that compared to middle-aged white men or Japanese-American men living in the United States, Japanese men living in Japan had twice the blood levels of omega-3 fatty acids—a finding that was independently linked to low levels of atherosclerosis.
