Hairpin turn: Micro-RNA plays role in wood formation

For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...

RNA folding: A little cooperation goes a long way

(Phys.org)—The nucleic acid RNA is an essential part of the critical process by which the cells in our bodies manufacture proteins. But noncoding RNAs also exist whose sequences, while not converted into proteins, play ...

Lessons from herbicide tolerance

(Phys.org)—Polyamines are widespread and important organic compounds involved in multiple cellular processes in living organisms. Their levels are highly regulated through a combination of processes including synthesis, ...

Getting inside the control mechanisms of complex systems

Northeastern University researchers are offering a fascinating glimpse into how greater control of complex systems, such as cellular networks and social media, can be achieved by merging the tools of network science and control ...

Old Cells Work Differently

The agglutination and accumulation of proteins in nerve cells are major hallmarks of age-related neurodegenerative illnesses such as Alzheimer's disease. Cellular survival thus depends on a controlled removal of excessive ...
