Several AIDS prevention advertisements from all over the world, taken from the Wellcome Images. The message is the same across all posters – learn about the risks of HIV/AIDS and practice safe sex. But every poster takes a different route in conveying the point across; the end result is a colourful and interesting display of images/photographs.

I know this is not science.. but I couldn’t help myself. Whether or not you subscribe to numerology, this date is pretty cool! Today is 12-12-12, the last major numerical date using the Gregorian or Christian calendar for almost another century. The next time we will have a date like today’s, will be the 1st of January 2101… I am not sure we will still be alive by then. So lets enjoy it whilst we can!! My grandmother was born 3.3.33 – EVEN COOLER!
Eight MIT biological engineering graduate students volunteered for a three-hour shift. They glued the amino acid side chain structures together for the LEGO protein kits.
Biology isn’t always easy to understand, especially for young kids. For me, the difficulty lies in the inability to really see what is happening, especially when you’re learning cellular processes. When you teach kids to count you use objects, you place them in piles and transfer them across from one pile to another. Fractions are often taught using the analogy of a cake cut into slices – the cake exists, you can eat the cake. You can see it. But how do you explain cell division to a child?
This memorable fictitious word, widely remembered for its use in Mary Poppins is now part of the Oxford Dictionary! Common belief is that it is an adjective used to describe something wonderful, fabulous. And this is the case indeed, that is if you’re talking about a wonderful state-of-mind! Continue reading →
Stubborn myths about the brain that just won’t die… EXPOSED.
The brain is too complicated for us to make sense of. In fact, to the majority of us, the brain is utterly alien. Most of us are perpetually unable to understand anything about the 1.5 kilogram mastermind sat snug on our shoulders. How do we deal with uncertainty? By creating fabrications and actively believing those brain myths circulating the web and dinner conversations.
FACT: our brains try to make sense of non-sense. How ironic. Can you tell which way is up and which way is down? Our brains keep shifting around the way we perceive the direction of the stairs – an example of the brain trying to make sense out of what does not make sense. So are we to blame..? Or maybe we’re just stubborn. Continue reading →
It has been our goal to visualise the brain since the Spanish scientist Santiago Ramón y Cajal (1852 –1934) began using a stain to mark and draw out individual neurons. He peered through the microscope to visualize single cells. “Here everything was simple, clear and unconfused” – he wrote of his observations. This was the beginning of modern neuroscience and since then numerous imaging techniques have been developed for the study of brain activity and brain structures. The result is living art.

Pi Day is an unofficial holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format). But today is also Pi day. July 22nd (or 22/7 in day/month date format) and the fraction 22⁄7 has a value of 3.142857. This has the same first three digits as pi… So yes, you do have to dig around to find it but the reasoning is there. The elusive little man, Constant π, actually gets commemorated on two separate days of the year.
I have been called Fat Cat by my family since prehistoric times. In fact, that was my first name. The one I use now is really just a pseudonym. I wanted to introduce to you another cat – Chemistry Cat. … Continue reading →
Its lovely to have this blog as an excuse to be geeky. To freely roam the web for biology chat up lines and to scratch my head trying to come up with my own. But I do think there is a problem – I have one hour to unwind and this is what I do in my relax time??
You’re so sweet I am developing insulin resistance.
Let’s convert our potential energy to kinetic energy.
I wish I were adenine because then I could get paired with U.
Hey baby, why don’t you get your ligase working on my okazaki fragment and lengthen my strand.
I will introduce the most basic and fundamental concepts of pharmacology. If this is too much then don’t worry, you’re forgiven. I think its necessary to at least have the basics written down on here so that I can refer back to the post if need be. Or perhaps whilst reading this you will discover a new passion for drug kinetics. (I am glad modesty doesn’t get in the way of my pipetting). Continue reading →
The Royal Pharmaceutical Society of Great Britain provides an excellent overview of the pharmaceutical symbols that enjoy widespread usage. This can be found here. I roamed the internet for a more detailed review of the most commonly recognizable symbols. Continue reading →
In Plato’s Phaedrus, the Egyptian god of writing offers King Thamus writing as a “remedy” (“pharmakon”) that can help memory. Thamus refuses the gift on the grounds that it will only create forgetfulness: for him, it is not a remedy for memory itself, but merely a way of reminding. Writing is thus a “poison” (“pharmakon”). The word “pharmakon” meant both the disease and its cure to the ancient Greeks. The word is paradoxical, translated as ‘drug’ and meaning both ‘remedy’ and ‘poison’. This is still the same today – we refer to both effective medicines and to toxic substances as ‘drugs’.
