Let's talk about root beer & why you've probably never tasted real sassafras OR sarsaparilla.
Root beer was originally made by adding yeast to a syrup made from the pulverized root bark of a sassafras tree.
Sassafras produces SAFROLE, a compound that deters animals from eating the bark or leaves.

One of the most salient lessons I learned in all my adventures with screening and protein engineering is the importance of context. The context in which you test a gene or protein determines what function it has.

After four months, the journal has not found a single reviewer for my PhD student's manuscript. The academic peer review system is broken.
I think we all should:
1. Review three papers for every one that we submit.
2. Promptly declined to review a paper when the request arrives.

"Mail" (letters & such) is from Old French 'male' which meant bag or satchel. It entered Middle English as "male" but acquired the connotation of "bag of letters/correspondence".

Happy to announce that our latest paper is now out! Have you ever wondered how neural tissues control their size? In this paper, we show that cell division orientation is critical in both the cortex and retina. www.science.org/doi/10.1126/...
Oriented cell divisions induce basal progenitors and regulate neural expansion across tissues and species
A fundamental role for division orientation in progenitor output driving cortical and retinal growth is revealed.
