A class of molecules called microRNAs may offer cancer patients two ways to combat their disease.
Researchers at Princeton University have found that microRNAs — small bits of genetic material capable of repressing the expression of certain genes — may serve as both therapeutic targets and predictors of metastasis, or a cancer’s spread from its initial site to other parts of the body. The research was published in the journal Cancer Cell. (more…)
PASADENA, Calif. — NASA’s Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.
Examination of loose rocks, sand and dust has provided new understanding of the local and global processes on Mars. Analysis of observations and measurements by the rover’s science instruments during the first four months after the August 2012 landing are detailed in five reports in the Sept. 27 edition of the journal Science.

For most animals, scent is the instant messenger of choice for quickly exchanging personal profiles. Scientists, however, have long dismissed birds as odor-eschewing Luddites that don’t take advantage of scent-based communications.
In a first-of-its-kind study, however, a Michigan State University researcher has demonstrated that birds do indeed communicate via scents, and that odor reliably predicts their reproductive success. The study appears in the current issue of Animal Behaviour and focuses on volatile compounds in avian preen secretions. (more…)
UD joins research team teaching robots to respond in disaster emergencies
How do you teach a robot to get into vehicle and drive it? Three University of Delaware professors plan to figure it out by the end of next year.
Christopher Rasmussen, Ioannis Poulakakis and Herbert Tanner are part of a team competing in a new U.S. Defense Advanced Research Projects Agency (DARPA) Challenge. The team, with members from 10 schools, led by Drexel University, is one of several groups worldwide working to advance robotics technology for disaster relief. (more…)
The wide swings in debate performances by this year’s presidential candidates reflect the fact that in modern campaigns, a candidate’s image is the message, according to linguistic anthropologists who have studied presidential campaigns.
Candidates send important messages to voters through even their smallest gestures, the researchers say. For example, in this year’s first debate, President Barack Obama often looked down at the podium and was criticized for appearing disengaged. In subsequent debates Obama directly addressed his Republican opponent, former Massachusetts Gov. Mitt Romney, and increased the use of a hammering hand gesture sometimes called the “power grip.” (more…)
*MU researcher finds negative language inspires further viciousness*
A University of Missouri study of recent political blogs indicates politics are getting nastier due to digital media, which are segmenting people into polarized interest groups. The researcher recommends a balanced approach to finding information in order to return civility to political discourse, which is at the heart of democracy.
“One side is going to lose in every political discussion,” said Ben Warner, associate professor of communication in the MU College of Arts and Science. “The danger with this open hostility found in digital media toward the other side in politics is that it undermines the legitimacy of the people that we disagree with politically. It’s important to recognize that people who disagree with you aren’t ‘evil’ or ‘trying to destroy America;’ they just have different perspectives.” (more…)
