A Kitty Cure?
Parasite helps fight tumors.
Toxoplasma gondii, a parasite commonly found in cat feces, made national headlines after being linked to rage disorder and schizophrenia. Now a new study published in PLOS Genetics by researchers from Geisel School of Medicine suggests that the parasite might also play a key role in fighting cancer. Previous experiments have shown that a vaccine derived from T. gondii Is highly effective at Increasing survival rates In mice by curing certain types of tumors. By systematically altering the genetic makeup of the parasite before Injecting It Into mice afflicted with aggressive ovarian cancer, the team, led by David Bzlk of the department of microbiology and Immunology, was able to determine the specific protein responsible for triggering a mouse’s antitumor Immune response. Researchers hope that the protein may one day be used to develop more effective Immunotherapy treatments for fighting ovarian cancer In human patients.

Pest Control
Plan targets tree-eating insects.
Non-native Insects such as the emerald ash borer and hemlock woolly adelgid cause billions of dollars In damage to North American forests and properties each year, according to an article published In the journal Ecological Applications. “The enormous costs of Invasive pests typically fall on landowners and local governments that cannot afford It. We need to become better—fast—at stopping human-aided transport of organisms among continents,” says Matthew Ayres, professor of biological sciences and one of the paper’s 16 coauthors. The study recommends a series of preventive measures aimed at reducing the spread of Invasive species via global trade and Improving the effectiveness of early detection and rapid response programs. “Success will require the engagement of voters, landowners and forest-enjoyers of all kinds,” says Ayers. “I hope that anyone who Is Interested In protecting our forests will contact their representatives In Washington, D.C., and ask them what they are doing to prevent the next emerald ash borer.”
