Building our own BioLab

One of our main aspects of doing igem everyear is making our own biolab from scrap, i.e jugaad. Using alternatives and different methods to carry out a completely different purpose. We started off with building a microscope from a webcam, and soon we were making a centrifuge out of a hand blender. We also made a laminar air flow, a desicator and an incubator from different materials. We built our own lab by constructing a geodesic 10 feet metal dome which we covered with tarp.

Featured in this image is our own DIY microscope, sterile hood, incubator and a geodesic Biodome which houses our entire lab.

Experiments at NCBS

We worked in the labs at NCBS, under the guidance of Navneet Rai.

The BioGeographer's toolkit

Before our expeditions to collect soil samples, we came up with a tool kit that holds all the essentials required to be carried on the field while working:

The First Prototype:

Fold-able cloth toolkit

Slab to store Epindorf tubes after soil sampling:

Epindorf Bag

Soil Sampler ..for stylish soil extraction

Outreach with Friends

As we all know aerial photography is quite expensive; owing to our tight budget, we had to come up with a simple and cheaper way of the same- balloon mapping.

We invited students from our campus to show them our cost effective way of aerial photography. They were quite impressed of how a easy it was to make a useful gadget out of simple day to day objects- helium filled balloons, a strong thread and a digital camera.

Watching some David Cronenberg

Shivers (a movie directed by David Cronenberg) is about a doctor’s attempts to bring out the inner sexual animal in man, using a parasite. He fooled his co-workers, and sponsors, into thinking that he was working on creating an alternative to organ transplant, by using parasites. The doctor was unable to accurately predict what the modified parasite would do. This lead to the parasite spreading from his teenaged mistress to quite a few other residents of a “sterile” high-end apartment block, and spreading uncontrollable sexual desire. This movie highlighted the unpredictable nature of the effects, the consequences of any modifications that we make in any organisms. It also highlights the unpredictability of the behaviour of the organisms. The behaviour of the modified organism in the laboratory is not adequate enough to predict its behaviour in the outside (real) world. The parasites modified an entire society and, in a manner, the entire purpose of a community.

We also watched The Fly...and here are a few of the reactions!

Some Early Speculative ideas

Spices like chillies & pepper feel "hot" beacuse they contain certain chemicals like capsaicin and piperine. Our body (mainly our mouth) feels a sensation of burning pain, as a result of these chemicals. Our sensory neurons contain a functional cDNA encoding for a capsaicin receptor. The receptor is a non-selective cation channel that is also activated by increases in temperature. Similarly, other spices will all have acting chemicals, mostly organic. Each spice will also have corresponding receptors, or mechanisms, to induce responses. Most of the spices and condiments used are plant parts. This implies that they do contain cells (living or dead. Cells contain DNA, which would be responsible for the production of the chemicals responsible for the flavours of the spices. We would be able to identify the exact DNA sequences that code for the necessary chemicals by DNA sequencing. Once the sequences are identified, they can be introduced into the DNA of a suitable, safe bacteria. This bacteria would produce the different chemicals (for the spices) in certain fixed quantities when introduced into the food. This would reduce the chances of dishes getting "spoilt" due to the usage of incorrect mixtures and quantities of spices.
