Asserting
people’s right to linguistic freedom, the Supreme Court has held that there is
no bar against a State Legislature declaring a language used in the State as an
official language for the convenience of its citizens.

Researchers
have flight-tested new mini robots that will protect the International Space Station (ISS) from
space junk and help repair defunct satellites. The space laboratory
regularly changes orbit to avoid colliding with derelict satellites, rocket
stages and other objects whizzing around Earth at huge xspeeds. These
robots may fly out to assess the danger presented by the vast array of objects
not already tracked by radar. Investigator Alvar Saenz-Otero and his
colleagues at the Massachusetts Institute of Technology (MIT) have built
several self-guided robots that are smaller than a soccer ball and fitted with
a 3D stereo camera. The images are relayed to the crew aboard the ISS,
who can decide how to proceed.
