PhD student in Plant Sciences at Cambridge working on dissecting the molecular basis of C4 photosynthesis. Formerly plant biologist, data analyst, bioinformatician and programmer at the Millennium Seed Bank.

My expertise is in plant biology, genomics, transcriptomics and computational biology.

I write software in Objective-C, C++, Ruby, Python, Javascript and R.

Solvers.io is my attempt to help highly skilled developers use their skills to benefit the world's poorest, or to help solve crucial scientific problems.

comment Height and natural selection in humans?
Excellent answer (you did a simulation!). Marta is right: mutation generates variation, but also human mate selection is not driven by height.

comment Are there any plants that fix their own nitrogen?
Well, by definition a food plant can't be a noxious weed, because they aren't noxious. But you raise a valid concern - mostly engineered traits such as vitamin A synthesis or herbicide tolerance are maladaptive and so they pose little risk of surviving outside deliberate cultivation for long. N fixation would be an adaptive trait in many habitats. Still, I don't think that's a reason not to do it, it's a reason to address the problem with a solution.

comment If I put a cup over a spider, and leave it there for a day, will the spider survive?
Good point about oxygen depravation, but I'd really like to see some links to references. Congrats on your first answer :)

comment Is Behe's experiment (evolving the bacterial flagellum) plausible in the lab?
It's true that directed evolution, by definition, is supposed to take a shortcut. But the likelihood of achieving the desired outcome is miniscule in this case, precisely because of the complexity of the organ. And whilst we might skip some of the non-contributory generations, we are talking many orders of magnitude difference between a human lifetime and evolutionary time. Previous directed evolution experiments have never achieved this. By a random evolutionary walk, we might see a simpler solution or none at all in human timescales in the lab.

comment How do I clean phenol contaminated RNA without losing any of the sample?
I did clean with isopropanol and Ethanol, and then Nanodropped afterwards. I take full responsibility!

comment Why do we age? or Do we have a theory of senescence?
That doesn't explain why we don't just reach sexual maturity and then stop aging - it can't be the primary explanation, although it would be a selective pressure once aging existed in the first place.

I must not be as good at pipetting as I thought! Thanks very much for your answer. I'll make sure I get better at pipetting and in the meantime I'll leave a safe amount of the aqueous phase behind.

comment How do I clean phenol contaminated RNA without losing any of the sample?
Which bit of pipetting is the crucial part? Is it the removal of the clear upper phase after centrifugation? If so - do most people leave a bit of the upper phase behind so as to avoid contamination? I was trying to get every last drop!

comment How does water buffer a sudden drop in temperature?
I think the updated question is a much better fit for this site, as you put it in a biological context. I think Rory's answer is the right one, perhaps he could expand it into a full answer?
