There is no life without a heart. And none without a beat. Which is why the heart is one of the first organs to be formed - albeit in a rudimentary fashion - very early on in life; as early as two weeks in the human embryo which, at that point, bears little resemblance to a human being. The heart is such a vital part of us that it has been a symbol of life for millennia, as it has of love, because so many of our emotions pass through it, either making it flutter, skip a beat or beat faster. It is so central that a lot of time, thought and energy is put into keeping a heart pulsing, be it during an operation or following cardiac arrest. Some hearts are also born lazy, which can be seriously disabling. Pacemakers are an answer to this, but they are artificial so have their drawbacks. A biological alternative, however, known as T-box transcription factor Tbx18, could prove to be revolutionary in the near future.

Our defense mechanism has no pity. Foreign matter for whom our organism can be a great playing field is rapidly dealt with. Virus, bacteria, pollen or even tumor cells face a merciless battle against the soldiers of our immune system: the white cells. Despite this, and however well-disposed these white cells may be, they cannot cross the cell barrier which isolates the brain from the rest of our body. So how does such a vital organ fight off invaders? The answer is: microglia.
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.”
