Greater risk of heart attack associated with Vioxx than Celebrex

In the first epidemiological study designed and executed specifically to determine the heart-attack risk associated with COX-2 inhibitors rofecoxib (Vioxx) and celecoxib (Celebrex), researchers at the University of Pennsylvania School of Medicine found a greater risk of heart attack associated with Vioxx than Celebrex, although neither of the two drugs showed a statistically significant elevated risk of heart attack relative to people who did not use the drugs.

Oxidants are responsible for sex in algae

Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidants within their cells activated the algae's sex-inducer gene, the researchers report.
