I'm sure you can still read the text to work out who the culprits were ...

The Deep Carbon Observatory is an international interdisciplinary project studying the hidden carbon fluxes deep within the earth, along with implications for life in the subsurface and on planet formation and development.
I've written a feature about this work which is out in Chemistry & Industry:
Chemistry & Industry March 2013, pp 32-35
The full text is freely accessible here.
The article is also featured on the cover of the issue:
In the same issue, I also have a review of the book "Synthetic biology: a primer", which appears on page 50.

Scientists are now able to design new enzymes to catalyse reactions for which a natural enzyme doesn't exist. I've rounded up some of the first success stories in enzyme design for my latest feature which is out now:

Moving on from first movement of the Beethoven Duo no. 1, we're now trying to play the third movement of the same piece, which is actually a little bit easier.
Here's the score:
As of 2021, the Flash view of the score disappeared, but this link is working.
This is mainly adapted from the Kalmus edition for violin and viola. A slightly different version is included in the duets for violin and cello from Editio Musica Budapest.
PS: Note that I added the first bar just to count me in and allow me time to get my hand back to the flute after pressing start.

I've now figured out what to do with DNA double helices of the wrong chirality, which I frequently see in print and online. Earlier I started compiling a hall of shame, but that might reinforce the wrong image (eg by adding to the already considerable proportion of wrong helices that show up in google searches for double helix).
Instead, I'm now going to flip the images that also contain text, such that the DNA will be the right way round and the text will be mirrored. This way, I can signal-boost the correct structure while also exposing the error.
So, for example, a poster I received yesterday now looks like this:
much better, huh?
The same treatment for the historic blunders of Nature and Science yields:

Ooops, now it's March and I haven't done the roundup of the German pieces published in February yet. Time, you're moving too fast.
So in Feb, we had quantum procrastination, reduction and oxidation at the sea floor, and cycloaddition with triple bonds:

My latest feature in Current Biology juxtaposes a highly acclaimed project to simulate the function of the heart and a somewhat controversial, but well-funded one to do the same for the brain.
Simulating hearts and minds

Here is a video about the Alya Red project featured in my article:
