Extraordinarily transparent compact metallic metamaterials

In materials science, achromatic optical components can be designed with high transparency and low dispersion. Materials scientists have shown that although metals are highly opaque, densely packed arrays of metallic nanoparticles with more than 75 percent metal by volume can become more transparent to infrared radiation than dielectrics such as germanium. Such arrays can form effective dielectrics that are virtually dispersion-free across ultra-broadband ranges of wavelengths to engineer a variety of next-generation metamaterial-based optical devices.

Sedimentary, dear Johnson: Is NASA looking at the wrong rocks for clues to Martian life?

In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks.

Selective application of contraceptives may be most effective pest control

Since the mid-20th century, the global human population has grown from 2.5 billion to 7.7 billion, according to the most recent United Nations estimate. Much of this growth was due to the unprecedented agricultural expansion made possible by the widespread use of synthetic pesticides starting in the 1950s.
