Science News Items or Facts - Themes This Week

There is sort of a theme this week. These are all things that people are proposing as solutions to problems. Scientists propose ejecting dust from the moon to act as a shield between the earth and sun in order to mitigate global warming. As mountain lion numbers increase, conservationists have proposed setting up traps that will die their fur pink or another bright color. neuroscientists propose using fMRI scanning to quantify subject reaction to a copycat trademark so they can see if it is too similar to an established trademark.
