- A tricky tumor virus
01-17-2008 · EurekAlert!
Viruses use many tricks to gain control over their host cells and to reprogram them to their own advantage. Dr. Arnd Kieser and his colleagues of the Department of Gene Vectors of the Helmholtz Zentrum Munich, Germany, were able to show in a recent publication in PLoS Biology by which mechanism Epstein-Barr virus exploits a signal protein of its host cell, which normally mediates programmed cell death, in order to convert the cell into a cancer cell.

- Getting to the core of an emergent public health threat
05-15-2007 · EurekAlert!
The outbreak of severe acute respiratory syndrome (SARS) in 2002 was a loud wake-up call for researchers studying infectious diseases. "The SARS outbreak was a strong reminder that new viruses can emerge, and whether new or old, pathogens can cause not only significant disease and death, but they can also have a global socioeconomic impact," said Brenda Hogue, an associate professor at the Biodesign Institute. Hogue has uncovered some key clues behind SARS-related viruses.

- An AIDS-related virus tricks cells to become tumors, new Penn study finds
11-08-2006 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine have discovered how the Kaposi's sarcoma-associated herpesvirus (KSHV) subverts a normal cell process in order to promote tumor growth. The finding, published in the most recent issue of PLoS Pathogens, offers new potential strategies for treating Kaposi's sarcoma and other cancers associated with viruses

- Cognitive lock-in: Why you can't teach an old dog new tricks
06-04-2007 · EurekAlert!
The ability to learn from experience is of central importance to human existence. It allows us to acquire the skills we need to complete complicated, multistep tasks in an efficient manner. It also creates habit -- a critical, if often overlooked factor in the choices consumers make. A new study from the Journal of Consumer Research demonstrates how this "cognitive lock-in" can cause us to remain loyal to a product, even if objectively better alternatives exist.

- New behavior may use old genes
10-25-2006 · EurekAlert!
Though you may not be able to teach an old dog new tricks, ASU researchers have found that evolution may have taught old genes new tricks in the development of social behavior in honeybees. The genetic basis of social behavior is being deciphered through the efforts of ASU researchers and their work with the honeybee, Apis mellifera.
