New Jersey Institute Of Technology Pioneers New Way To Teach Engineers
In Professor Richard Foulds' freshman design class, students perform angioplasty on pasta, amniocentesis on jelly donuts and surgery on hot dogs. Foulds, along with other professors at New Jersey Institute of Technology (NJIT), is pioneering a new way to educate engineers. Professors who use the method, called studio learning, demonstrate the fundamentals of engineering not by lecture and recitation but by active, hands-on, experiment-based learning. Conservation of the Dred Scott Papers
Description of the conservation of papers from the case in which "Dred Scott petitioned the St. Louis Circuit Court for his freedom in April 1846."The case, which eventually went to the U.S. Supreme Court and was decided on March 6, 1857, "brought the country to the brink of civil war."Includes many images showing the conservation process.

The gene expression profile detected in the core needle biopsy of a breast tumour is representative of gene expression in the whole tumour. A study published today in the open access journal Breast Cancer Research confirms the reliability of core needle biopsy as a tool in breast cancer diagnosis and prognosis. How One Virus Uses Mimicry To Replicate Successfully: Related Mechanis
Both viruses and cancers subvert the growth-control machinery in a cell to serve their own needs. According to a new study, at least one virus uses mimicry to gain access to that machinery. A common target for both is a cell protein called the retinoblastoma protein, or pRb, which serves to block cell division when potentially cancer-causing gene mutations are present. Krakatoa: Volcano of Destruction
Companion to a "dramatized documentary that reconstructs the weeks before, and the struggle for survival during ... [the] cataclysmic eruption"in 1883 of the Krakatoa volcano. Features video clips, survivor diaries, a build-you-own volcano interactive feature, an illustrated essay, and puzzles. From Discovery Channel. Scientist Refines Cosmic Clock To Determine Age Of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. Dauphas' method, which he reports in the June 29 issue of the journal Nature, can now be used to tackle other mysteries of the cosmos that have remained unsolved for decades. Color Contrast Is 'Seen'By The Brain Early Doors
Color contrast is detected much earlier in the brain than previously thought, a new study shows. The research also confirms that the brain does most of the work in seeing the difference between colors, rather than the eye. Sexual Conflict Resolution? Mating Frequency And Fitness In Fruit Flie
In the gene's eye view, female mating frequency is difficult to understand. A substantial body of evidence, taken throughout the animal kingdom, demonstrates that females mate frequently, even when bouts of mating decrease offspring production. This finding is counterintuitive because we would expect natural selection to remove mating behaviors which decrease fitness. However, new research suggests that frequent mating females receive fitness benefits from an unexpected source: their daughters. People With Genetic Predictors Of Colorectal Cancer Are Not Getting Sc
Even when diagnosed with a condition that is a strong genetic predictor of colorectal cancer, many patients do not seek out genetic counseling or cancer screening. According to a recent study in the American Journal of Gastroenterology, counseling and screening rates could be improved if physicians provided stronger encouragement and more complete information about the benefits of screening to their patients. Desktop hockey face-off
Scientists sure know how to have fun, Iain “Beaker” Larmour and Lauren “Comical Flasks” Rutherford of QUB, in Norther Ireland, square up for the match of the century playing micro mechanical hockey on a super water repellent, a superhydrophobic, material, that makes a duck’s back look positively damp.There is a serious objective to this work.
