Researchers found that across the U.S., anal cancer incidence and mortality rates increased 1.5-fold in men and women over 50 years old. However, the most prominent increase -- more than two-fold -- occurred among people over 50 years of age living in the Midwestern and Southeastern states.
Have humans wreaked too much havoc on marine life to halt damage? A new analysis challenges the idea that ocean ecosystems have barely changed over millions of years, pointing scientists down a new path on conservation efforts and policy.
Researchers have developed a new strategy to help build materials with unique optical, magnetic, electronic and catalytic properties. These pinwheel-shaped structures self-assemble from nanoparticles and exhibit a characteristic called chirality -- one of nature's strategies to build complexity into structures at all scales, from molecules to galaxies.
