High-resolution satellite imaging of the Amazon basin reveals previously undetectable selective logging and forces a doubling of estimates of forest degradation rates.

Cytoplasmic organelles called P-bodies cannot only degrade mRNA but can store it for later release into the translation machinery.

Infection of cultured neurons with inactive prions that otherwise cause Creutzfeld-Jakob Disease and scrapie can prevent subsequent infection by other prion strains, consistent with in vivo results.
