Did you know a scorpion can control how much venom it produces in its stinger? Meet a scientist who's discovered more than 70 species of scorpions and find out what he's learned about them.
I went on a class field trip to Fernwood Botanic Garden in southwest Michigan when I was in sixth grade. When we toured the restored prairie, the naturalist told us about invasive non-native plants such as garlic mustard and how they destroy native habitats...
If technology, cost, and terrain permitted, scientists seeking key data on stars in our galaxy would have loved to construct a behemoth 330 m wide telescope atop Mount Wilson, just northeast of Los Angeles. Instead, they arranged six smaller telescopes over an identical area, synchronizing the light to achieve an equally superlative resolution. Called the Center for High Angular Resolution Astronomy (CHARA), the array uses the technique of interferometry to spot details the size of a nickel seen from 16,000 km away. Hear from project astronomers why the labyrinthine engineering required for CHARA's renowned precision is a small sacrifice for the valuable data it gleans on the properties and life cycles of stars.
Launched on December 14, 2009, the WISE space telescope is helping scientists create a Digital Universe 3-D Atlas. Take a look at WISE and the data it is capturing.
