Viruses: Engineering on the nanoscale
The image for April in our 2018 calendar depicts a single Zika virus protein in addition to the full Zika virus capsid. In this feature we discuss the transition between these two structures and demonstrate the beautiful simplicity of virus assembly.

Gin, with a twist
Much like a food mixer, with interchangeable tools that render it suitable for whipping, beating or liquidising, bacterial RNA polymerase has an exchangeable subunit called a sigma factor which adapts it to different programmes of gene expression. Sigma factors are controlled by other proteins called anti-sigma factors, to make sure the polymerase doesn’t whip when it should be liquidising.

A powerful little motor
The image for March in our 2018 calendar shows a pathogenic bacterium, the structures that enable it to interact with the environment, and the powerful molecular motor that drives those structures.

Polio- A resolution to eradicate
The near-eradication of poliomyelitis is one of the great success stories of modern medicine. The image in our 2018 calendar for February shows the virus which causes it, and highlights one of the amazing developments in modern structural biology.

Quinine: Barking up the right tree
The final image in our 2017 calendar shows an important enzyme along with the plant that produces one of its best known substrates. You might drink some if you have a Christmas G&T.

The human genome codes for 20-25,000 proteins. The lab workhorse bacterium, E.coli, codes for around 2,300. Every single one of those proteins is produced by the huge molecular machine shown on our 2017 calendar image for November.

Opening a Gate to Human Health
In the 1970s, an exciting discovery of a family of medicines was made by the Japanese scientist Satoshi Ōmura. It is one of these molecules which features in the October image in our 2017 calendar.

The image from our 2017 calendar for August is inspired by a molecular cartwheel which is essential for the mobility of single celled parasites called trypanosomes. Trypanosomes are the causative agents of several potentially fatal human diseases, including Leishmaniasis, Chagas disease and Sleeping Sickness.
