GREEN PEA GALAXIES REVEAL SECRETS OF LyαESCAPE

‘Cryptic’ exons reveal some of their secrets

By regulating the inclusion of 'cryptic' exons in messenger RNA in nerve cells, NOVA proteins are able to influence the abundance of the corresponding proteins.

MicroRNAs: Genetically Sensitized Worms Reveal New Secrets

Why do many microRNA gene mutants display no evident phenotype? Multiply mutant worms that are selectively impaired in genetic regulatory network activities have been used to uncover previously unknown functions for numerous Caenorhabditis elegans microRNAs.

Cretaceous avian crops reveal dietary secrets and pose evolutionary questions.

A mong the most striking avian anatomical divergences from the typical tetrapod pattern is the reduction of the cephalic alimentary canal to a bare minimum required for food procurement, generally believed to be an adaptation for lightening the avian body for flight (1). Much of this anatomical modification involved jettisoning teeth concomitantly with the acquisition of a horny beak, the reduc...

Strippers Reveal Their Depressing Secrets: Removing AMPA Receptors

How do microglia regulate synaptic function? In this issue of Neuron, Zhang et al. (2014) describe a novel form of long-term depression of AMPA receptor-mediated synaptic transmission in the hippocampus involving the activation of microglia.
