Before the pancreas is a pancreas, it is just two tiny bumps–two groups of cells sprouting from a central tube. What makes these cells bud off from the main group? How do they go on to make all the cell types of the mature pancreas? These are the kinds of questions that drive the research efforts of Vanderbilt developmental biologist Chris Wright and colleagues. The answers could pave the way toward limitless supplies of pancreatic cells for transplantation therapy of diabetes.

In the future, a “broccoli-pill” a day may help keep breast cancer at bay. Researchers have developed a new compound, designed from a known anticancer agent found in broccoli, that shows promise as a breast cancer preventive.
Apparently less toxic than its natural counterpart, the compound could be marketed for cancer prevention, the researchers say. Their findings were described at the 224th national meeting of the American Chemical Society, the worlds largest scientific society.
Australian researchers have created the ideal manufacturing material of the future – clean, green ‘super steel’ that is double the strength of normal steel and resistant to fracture.
“Stronger steel means less material is required to support a load or resist a force, which should lead to lighter structures and vehicles,” says Deakin University researcher, Dr Georgina Kelly.
“This would deliver reduced energy needs and emissions in cars, and greater potential to develop more complex
Researchers at Purdue University have made a surprising discovery that could open up numerous applications for metal “nanocrystals,” or tiny crystals that are often harder, stronger and more wear resistant than the same materials in bulk form.
The research engineers have discovered that the coveted nanocrystals are contained in common scrap, the chips that are normally collected and melted down for reuse.
“Imagine, you have all of these bins full of chips, and they get melted down
A DMS professor is leading the way in using computer technology for medical education with a pioneering virtual clinic to teach “Genetics in Clinical Practice.” Joseph V. Henderson, MD, a professor of community and family medicine who heads Dartmouth Medical Schools Interactive Media Lab (IML), created a “virtual practicum in genetics” using state-of-the-art interactive multimedia and world leaders in genetics research to foster more effective continuing medical education at DMS.

Researchers from Woods Hole, Scripps oceanographic institutes sail on new Coast Guard ice breaker to study climate, ocean changes
A University of Massachusetts Amherst geoscientist is part of a team of researchers sailing the Bering and Chukchi seas this summer, searching for clues about the sea floor history and the land bridge that once existed between what is now Alaska and Russia. The team will also explore how the disappearance of the land bridge may have affected that region
