Hidden messages in protein blueprints

For this purpose, the stem cells simultaneously modify the blueprints for hundreds of proteins encoded in the gene transcripts. In this way, they control the amount of protein produced and can also control the formation of certain proteinisoforms. If this mechanism is inactivated, stem cells lose their self-renewal potential and can no longer react adequately to danger signals or inflammation.

The strange orbits of 'Tatooine' planetary disks

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.
