How to rule a gene 'galaxy': A lesson from developing neurons
A new study has found that many RNA messengers encoding neuronal proteins contain specialized sequences that can promote their destabilization in the presence of an RNA-binding protein called tristetraprolin, or TTP.

Prion trials and tribulations: Finding the right tools and experimental models
Prions are fascinating, enigmatic, and might teach us not only about rare prion diseases like Creutzfeld-Jakob disease, mad cow disease, or scrapie, but also about other more common neurodgenerative diseases. Two studies report progress with novel tools and paradigms to study prion disease.

What bee-killing mites can teach us about parasite evolution
An infestation of speck-sized Varroa destructor mites can wipe out an entire colony of honey bees in two to three years if left untreated. Pesticides help beekeepers rid their hives of these parasitic arthropods, which feed on the blood-like liquid inside of their hosts and lay their eggs on larvae, but mite populations become resistant to the chemicals over time.

First comprehensive analysis of the woolly mammoth genome completed
The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt Arctic life, including skin and hair development, insulin signaling, fat biology, and even traits such as small ears and short tails. A mammoth gene for temperature sensation was resurrected in the lab as a functional test.
