Fair Games against an All-Powerful Adversary

Suppose that a weak (polynomial time) device needs to interact over a clear channel with a strong (in nitely-powerful) and untrustworthy adversarial device.

However, to keep the game fair, the weak player must hide info...

Powerful Skin Cancer Protection by a CPD-Photolyase Transgene

BACKGROUND The high and steadily increasing incidence of ultraviolet-B (UV-B)-induced skin cancer is a problem recognized worldwide. UV introduces different types of damage into the DNA, notably cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs). If unrepaired, these photolesions can give rise to cell death, mutation induction, and onset of carcinogenic events, but the relati...

Caloric restriction: powerful protection for the aging heart and vasculature.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the United States. Research has shown that the majority of the cardiometabolic alterations associated with an increased risk of CVD (e.g., insulin resistance/type 2 diabetes, abdominal obesity, dyslipidemia, hypertension, and inflammation) can be prevented, and even reversed, with the implementation of healthier die...
