UA undergraduate researcher Ersilia Anghel has been collecting artistic photographs of minerals, plants, animals and humans, illustrating the intersections between the arts and sciences.

Scientists and artists have long collaborated to produce illustrative images and paintings of medical procedures, human anatomy and botanical displays.

But with the emergence of new, advanced technologies, scientists have begun to more readily produce their own photographic works, often times revealing the aesthetics of another world around us. (more…)

*Technique could be used to direct growth of blood vessels or tissues in the laboratory*

Christian Santangelo, Ryan Hayward and colleagues at the University of Massachusetts Amherst recently employed photographic techniques and polymer science to develop a new technique for printing two-dimensional sheets of polymers that can fold into three-dimensional shapes when water is added. The technique may lead to wide ranging practical applications from medicine to robotics

The journal Science publishes the research in its March 9 issue. (more…)

UCLA stem cell researchers have shown that insulin and nutrition prevent blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory response and blood development in response to dietary changes in humans.

Keeping blood stem cells, or progenitor cells, from differentiating into blood cells is important as blood stem cells are needed to create the blood supply for the adult fruit fly. (more…)

ANN ARBOR, Mich.— Nerve gases are colorless, odorless, tasteless and deadly. While today’s soldiers carry masks and other protective gear, they don’t have reliable ways of knowing when they need them in time. That could change, thanks to a new litmus-like paper sensor made at the University of Michigan. (more…)
