Gatekeeping proteins to aberrant RNA—'You shall not pass'

They found that RNA-binding proteins are regulated such that gateway proteins can recognize and block aberrant strands of genetic code from exiting the nucleus. Unused messenger RNA (mRNA) strands that cannot exit the nucleus ...

Poor air quality kills 5.5 million worldwide annually

New research shows that more than 5.5 million people die prematurely every year due to household and outdoor air pollution. More than half of deaths occur in two of the world's fastest growing economies, China and India.

In defence of pathogenic proteins

Protein deposits in cells, such as those associated with diseases like Parkinson's and Alzheimer's, can also be beneficial—at least for yeast cells, as biochemists at ETH Zurich have discovered. The researchers found a ...

Cellular damage control system helps plants tough it out

As food demands rise to unprecedented levels, farmers are in a race against time to grow plants that can withstand environmental challenges—infestation, climate change and more. Now, new research at the Salk Institute, ...

In a role reversal, RNAs proofread themselves

Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors every step of the way. There are separate, specialized enzymatic machines ...
