Hi all,

I don’t know how it’s possible, since I’m pretty convinced that it’s still early-mid January, but somehow our March issue has gone live. This issue is jam-packed with interesting science, including zebrafish-insect hybrids, vitamins gone wild, and click chemistry crossed with kinases (try saying that three times fast!).

In addition, we have (as always) our editorial, which for this month focuses on the unique challenges of publishing in interdisciplinary fields. In our experience, these challenges primarily arise from the different interests and expectations of widely varied scientists, whether in a collaborative or author/referee relationship. In putting together the editorial, we heard a few anecdotes of scientists from different fields trying to coordinate their sense of what aspect of a research project is most interesting, or what conclusions are reasonable based on a given data set. Do you have any experiences that stem from this intellectual divide? Or do you have any advice for scientists looking to get started in your field? Or, most importantly, what would you do with your own fish-insect hybrid?

As always, thanks for reading!

The whiff of yeast might help determine lifespan.

Eating less can lengthen an animal’s life. But now it seems that — for flies at least — they don’t have to actually cut down on the calories to benefit. Fruitflies can boost their lifespan just by not smelling their food.
