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.

Penn Study: Targeting Downstream Proteins in Cancer-Causing Pathway Shows Promise in Cell, Animal Model

PHILADELPHIA — The cancer-causing form of the gene Myc alters the metabolism of mitochondria, the cell’s powerhouse, making it dependent on the amino acid glutamine for survival. In fact, 40 percent of all “hard-to-treat” cancers have a mutation in the Myc gene.

Accordingly, depriving cells of glutamine selectively induces programmed cell death in cells overexpressing mutant Myc.

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.
