If Martian life existed a few billion years ago, scientists think any plant-like microbes would have left behind a stringy fuzz of fibers. That's because here on Earth, researchers now say they have found such ancient fuzz, called cellulose, preserved in chunks of salt deposited more than 250 million years ago -- making it the oldest biological substance yet recovered. The announcement comes about a week after a team of planetary scientists announced discovering evaporated salt...

Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature. Mark Schoenfisch and his lab of analytical chemists at UNC have created nano-scale scaffolds made of silica and loaded with nitric oxide (NO) "“ an important...

By Sabia, Joseph J Controlling for a wide set of individual- and family-level observables available in the National Longitudinal Study of Adolescent Health, ordinary least squares (OLS) estimates show that sexually active adolescents have grade point averages that are approximately 0.2 points lower than virgins. However, when information on the timing of intercourse decisions is exploited and individual fixed effects are included, the negative effect of sexual intercourse disappears for...
