Retroviruses (red) form in infected cell and are transmitted to neighboring cell. (upper right) Green proteins bind the cells.Retroviruses such as HIV that are already within cells are much more easily transmitted when they are next to uninfected cells than if they are floating free in the bloodstream.

"Cell-to-cell transmission is a thousand times more efficient, which is why diseases such as AIDS are so successful and so deadly," said Walther Mothes, associate professor of microbial pathogenesis at the Yale School of Medicine. "And because the retroviruses are already in cells, they are out of reach of the immune system."

Russell PoldrackCan neuroscience read people's minds? Some researchers, and some new businesses, are banking on a brain imaging technique known as functional magnetic resonance imaging (fMRI) to reveal hidden thoughts, such as lies, truths or deep desires.

New research by neuroscientists at UCLA and Rutgers University provides evidence that fMRI can be used in certain circumstances to determine what a person is thinking. At the same time, the research suggests that highly accurate "mind reading" using fMRI is still far from reality. The research is scheduled to be published in the October 2009 issue of the journal Psychological Science.

University research is becoming an increasingly important source of the innovations that fuel today’s successful companies.  With more than $400 million in research, Georgia Tech’s innovation engine produces more than 300 invention disclosures annually.  These innovations have led to formation of a broad range of new companies.

Georgia Tech VentureLab provides comprehensive assistance to Georgia Tech faculty members, research staff members and graduate students who want to form startup companies to commercialize the technology innovations they have developed.

 Future medical therapies will increasingly focus on interrupting and redirecting pathologic biopathways at the genetic and cellular level. Imaging – especially molecular imaging - will play an indispensible role in the understanding of biopathways, the creation of biospecific interventions, and the monitoring and control of new, highly potent interventions.

Howard Hughes Medical Institute researchers are reporting the first detailed molecular snapshots of a deadly gastrointestinal virus as it is caught in the grasp of an immune system molecule with the capacity to destroy it. The images could help scientists design a more effective vaccine against rotavirus, a lethal infection that kills more than 500,000 children worldwide each year. The discovery is timely.

The Hubble Space Telescope is a powerful orbiting telescope that provides sharper images of heavenly bodies than other telescopes do. It is a reflecting telescope with a light-gathering mirror 94 inches (240 centimeters) in diameter. The telescope is named after American astronomer Edwin P. Hubble, who made fundamental contributions to astronomy in the 1920's.
