This was no ordinary noise, that they knew of. In a recent interview on NPR, Dr. Simone Baumann-Pickering, Scripps Institution of Oceanography (La Jolla,…

Back in the old days, yesterday, making comments on the mobile version of Scienceblogs.com was sometimes difficult because the thingie at the bottom of the post that suggests the other wonderful blog posts you might want to visit tended to cover up the comments.
