Penn-Led Research Suggests a New Strategy to Prevent or Halt Periodontal Disease

PHILADELPHIA — Periodontitis, a form of chronic gum disease that affects nearly half of the U.S. adult population, results when the bacterial community in the mouth becomes unbalanced, leading to inflammation and eventually bone loss. In its most severe form, which affects 8.5 percent of U.S. adults, periodontitis can impact systemic health.

El Yunque Rock, an Icon of Puerto Rico, Is Eroding More Slowly Than Expected, Penn Geologists Discover

PHILADELPHIA — El Yunque rock is a majestic, anvil-shaped promontory that has been an icon of the island of Puerto Rico since pre-Columbian times. The barren rock, standing 3,412 feet high, protrudes above primary old growth forest and is enshrouded in clouds, swept constantly by the trade winds and frequently stricken by hurricanes. The rock receives an average of three rain showers a day and more than 14 feet of rain every year. Given Puerto Rico’s warm and dynamic tropical climate, El Yunque should be covered with vegetation and eroding rapidly.

A Comparative Medicine Study by Penn Vet Identifies a New Approach to Combat Viral Infections

PHILADELPHIA — When a virus such as influenza invades our bodies, interferon proteins are among the first immune molecules produced to fight off the attack. Interferon can also play a role in suppressing tumor growth and the effects of autoimmune diseases, and doctors may use an artificial form of interferon to treat patients with certain cancers or multiple sclerosis. But even this approach sometimes fails when patients’ bodies reject the foreign interferon or growing resistant to its effects.
