There are many proteins crouching in the recesses of databanks whose role in vivo eludes researchers. Despite similarities of all kinds they may share with other proteins, they seem to have been designed for another purpose. A few of them may even have an unexpected function in an organism that does not synthesize them at all - much in the way a pair of scissors can be used to hammer a nail into the wall. This is precisely the case of a protein known as gamma-conglutin, found in the seeds of lupins. Unlike the majority of proteins in lupin seeds, gamma-conglutin does not seem to be used as a source of nourishment for seedlings. However, it does have an effect on sugar levels in our blood! Lupin seeds have been part of our diet in various parts of the world for centuries and their beneficial effects on our health long acknowledged. Today, thanks to technological advances, scientists are able to discern what is going on at the molecular level.

Snapshot : Sonic hedgehog protein
Animals have such a keen sense of smell that in most instances they are literally led by their noses. In humans, however, such a sense seems to be more of a luxury than a necessity. Despite this, the mechanisms underlying human olfactory perception have been under close scrutiny for decades. Indeed, one part of our brain – the olfactive bulb – which is in effect the relay between our nose and our brain happens to be supplied with brand-new neurons on a daily basis.
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.”
