It was a day Christian Njatcha will never forget. A graduate student in pharmacology, Njatcha was examining mice with lung cancer with one question in mind: Could the proto-drug he had given them defeat the disease? Answer: It could. The tumors had shrunk, and the mice were doing well. “That […]

For some animals, such as salamanders, regrowing a missing limb is a common healing process. But what if people could do the same? Could the future of treating amputations include warfighters regrowing their own muscle, bone, and nerve tissues? “We’re not quite there yet,” said Army Lt. Col. David Saunders, […]

Individual tumors respond differently to cancer drugs, if at all. Until now, it remained a mystery why tumors have different reactions to the exact same therapy. But a new study at the USC Viterbi School of Engineering finds that tumor growth properties can influence response to cancer drugs. “Identifying a […]

The air we breathe contains particulate matter from a range of natural and human-related sources. Particulate matter is responsible for thousands of premature deaths in the United States each year, but legislation from the U.S. Environmental Protection Agency (EPA) is credited with significantly decreasing this number, as well as the […]

In the journey from egg to embryo to mature organism, our bodies stretch and wrinkle and fold like a fabulously intricate piece of origami. Now UC San Francisco bioengineers have shown that many of the complex folded shapes that form mammalian body plans and internal tissue structures can be re-created […]
