The Regulation Game: The key to controlling cellular microRNA levels

What can viruses, culprits of the flu, or even worse pathogens teach us about our biochemistry? For decades, viruses have brought scientists from a wide swath of specialties together and proven to be a hotbed of discovery because their relatively

Follow the Energy, See Where it Goes: Investigating the energetic expenditures of embryonic cleavage divisions

Energy is a tricky concept. The term is bandied around within and without science; even among scientists, “ener­gy” takes different meanings in different contexts. Though it is far from straight­forward to define what energy actually is, more important is what

Getting the Signal: Elucidating the chemical crosstalk driving ovarian cancer

Cells are notoriously chatty. Communication between different cell and tissue types is happening constantly in any multicellular organism, and this crosstalk is critical to survival. In humans, chemical signaling pathways ensure that information in one tissue can be shared with

Discovering the evolvability of RNA structures We often think of “evolution” as the work of millennia: a slow but steady process by which species diversify and gradually adapt to different environmental niches. On a much smaller scale, evolution must also
