Life can be hard. There are times when you find yourself in the most unfriendly circumstances and, more often than not, the best way to deal with the situation is to find your own solution and wriggle your own way out. Living species are the most imaginative of beings when it comes to designing defence mechanisms. Some release nasty smells to ward off predators, or melt into the landscape and become invisible to them. While others live in protective shells, inject toxins that paralyse, or are simply wise enough to walk away from danger. Many species have also chosen to live in places no one would ever dream of settling down in and, over time, have developed ways to flourish in severe temperatures, faced with a total lack of water and under crushing pressures. Among these are tardigrades, also known as water bears or moss piglets. One tardigrade in particular, Ramazzottius varieornatus, lives in very harsh conditions and even seems to have found a way to survive harmful radiation. Thanks to a protein which has been dubbed damage suppressor protein.

Snapshot : Cupidin
A protein neither short nor long
Whose arrow flirts with the brain
And knows how to touch the heart
Whose coiled coil has seduced many
From glutamate receptors to the actin cytoskeleton.
A little bit of praise!
“I recently stumbled upon your columns. Let me congratulate you on achieving the near impossible, for your articles have enabled me to successfully marry IT with the Life Sciences and better explain the concepts of bioinformatics to those who are not in the know of the field.
Your articles are very well written, lucid, and contain just enough information to excite the reader to want to learn more about the topic being discussed. They fall in a very rare category where they are accessible to everyone, from the undergraduate students to research students who want to have a basic idea of the topics being discussed. Some of your articles, like "Our hollow architecture" and "Throb" are outstanding pieces.
I would highly recommend your articles as a necessary reading in undergrad classes to get students inspired about the various avenues of research.”
