Science Outreach : Getting Started is Easy!

Sharing scientific knowledge is a fundamental part of university life. Regardless of whether you’re an undergraduate or a tenured professor, everyone has the responsibility of spreading their knowledge as widely as possible.

Why would you want to, though? “For a variety of reasons,” answers William Raillant-Clark, Press attaché at Université de Montréal’s Office of Communications and Public Relations. “The media is an excellent vehicle for communicating your ideas or your discoveries to the general public, and it can also draw the attention of your research peers to your work. This is one of the reasons why funding partners and potential research directors take into consideration science outreach work.” (more…)

A Half-Billion Stars And Galaxies From NASA’s WISE Mission Revealed — Many For First Time

A new atlas and catalog of the entire infrared sky with more than a half-billion stars, galaxies and other objects captured by NASA’s Wide-field Infrared Survey Explorer (WISE) mission was unveiled by NASA Wednesday.

“Today WISE delivers the fruit of 14 years of effort to the astronomical community,” said Edward L. (Ned) Wright, a UCLA professor of physics and astronomy and the mission’s principal investigator, who began working on the mission in 1998. (more…)

Hiding in Plain Sight, A New Frog Species With A ‘Weird’ Croak is Identified in New York City

In the wilds of New York City — or as wild as you can get so close to skyscrapers — scientists have found a new leopard frog species that for years biologists mistook for a more widespread variety of leopard frog.

While biologists regularly discover new species in remote rain forests, finding this one in the ponds and marshes of Staten Island, mainland New York and New Jersey — sometimes within view of the Statue of Liberty — is a big surprise, said the scientists from UCLA, Rutgers University, UC Davis, and The University of Alabama who worked together to make the unexpected discovery.

Loss of Appetite Deciphered in Brain Cell Circuit

The meal is pushed way, untouched. Loss of appetite can be a fleeting queasiness or continue to the point of emaciation. While it’s felt in the gut, more is going on inside the head.

New findings are emerging about brain and body messaging pathways that lead to loss of appetite, and the systems in place to avoid starvation. (more…)

Another World, Magnified

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…)

Researchers ‘Print’ Polymers That Bend Into 3-D Shapes

*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…)

Insulin, Nutrition Prevent Blood Stem Cell Differentiation in The Fruit Fly

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…)
