"Ho ho, ha ha ha," students in a fitness class at the University of Michigan Health System chant repeatedly while clapping their hands and walking around the room. They're just getting warmed up; in the next half-hour, they will stretch their muscles and work on breathing exercises. They'll also laugh for most of the 30 minutes, from self-conscious giggles to uninhibited belly laughs. All in the name of fitness. Source: ScienceDaily: Latest Science News | 6 May 2008 | 9:00 pm
Scientists have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. They also have shown that this type of laser, when used as a frequency comb -- an ultraprecise technique for measuring different colors of light -- could boost the sensitivity of astronomical tools searching for other Earthlike planets as much as 100 fold.

Methanol fuel cells are an efficient and sustainable alternative to fossil fuels, but they are still not economically viable. Now, a University of the Basque Country research chemist has developed new materials that enable the manufacture of cheaper and more efficient methanol fuel cells.

The incidence of a strain of tuberculosis (TB) called Mycobacterium bovis, or M. bovis, associated more often with cattle than humans, is increasing in San Diego and is concentrated mostly in Hispanics of Mexican origin, according to a new study. The analysis shows that changing patterns of TB in the United States are increasingly being driven by conditions outside of the country, especially in binational communities.

Paleontologists have long been perplexed by dinosaur fossils with missing pieces -- sets of teeth without a jaw bone, bones that are pitted and grooved, even bones that are half gone. Now a Brigham Young University study identifies a culprit: ancient insects that munched on dinosaur bones. Source: ScienceDaily: Latest Science News | 6 May 2008 | 6:00 pm
A process of self-digestion called autophagy prompts the maturation of red blood cells. Without a protein called Nix, the cells would not effectively rid themselves of organelles called mitochondria and consequently become short-lived, leading to anemia, said researchers at Baylor College of Medicine in Houston in a report that appears online in the journal Nature.

A specially coated metal tube, no larger than a cigarette, could be the key to developing an artificial pancreas to help millions of people with diabetes avoid insulin injections, according to an article in Chemical & Engineering News. The so-called "bioartificial pancreas" also could help keep blood sugar closer to normal levels, and perhaps reduce the risk of diabetic complications, which include blindness, kidney failure, and premature death, the article suggests.

Brain-training efforts designed to improve working memory can also boost scores in general problem-solving ability and improve fluid intelligence, according to new research. Many psychologists believe general intelligence can be separated into "fluid" and "crystalline" components. Fluid intelligence --- considered one of the most important factors in learning --- applies to all problems while crystallized intelligence consists of skills useful for specific tasks.
