It is amazing how much thought and science goes into producing food substances that we take for granted. The real wasabi owes its fiery nature to a volatile chemical called allyl isothiocyanate that binds to specific receptor in humans called TRPA1 – (Transient receptor potential) that is activated by heat in some instances. This allyl…
The video below explains it all. But essentially our perception is dependent on what we see. Wonder how many of these effects exist without us realizing it {youtube}FefFfvriAwQ{/youtube}
When we think of internet, it seems amazing to see that there are so many computers connected. This was made possible by the internet protocol version 4 provides 232 (4,294,967,296) addresses even though not all of them are usable. There are mostly saturated and the total number becomes about 4.2 billion and that is about…
The lab is an important place where discoveries are made, whether the lab is virtual or whether the lab is a physical space where experiments are conducted. It is also a place where the data is acquired, compared and finally conclusions drawn to make the discoveries possible. One feature that is common to most labs…
There have been many ways that people use standards for fluorescence but the one big one that has been used in flow cytometry and imaging. The one area that has developed a lot is the use of plastic fluorescent beads as controls. There are obviously many companies that have developed that but the one company…
There are several things that were considered odd by western medicine but have been proven much later to be useful. Consider these two examples: Stitches during surgery: In Kenya, Uganda and parts of South Africa, doctors or sham-doctors used ants to treat a wound. This was considered odd by western medicine. However, what is interesting…
There are many potential cell phone based applications but the firsn to get approved for Diabetes is iBGstar from Sanofi Aventis. This is a good compromise is using the dipstick based technology and then combining it with iPhone to read out the results. All this ends up replacing is the little electronic device that used…
How do you access 200 Terabytes of data? NIH is collecting data of many genomes that are being stored as computer code. These are then stored for researchers to access for their purpose. Being NIH, these large data sets are available for free. But, how do you process this amount of data. About the only…
Big data exists in different forms. Cold Spring Harbor Laboratory has worked to digitize the entire mouse brain. Each of the different regions of the brain can be seen and visualized. The data is estimated to be about 500 Terabytes but the fantastic thing is that it is available for anyone to see and download….
Dr Dharmendra Modha’s group at IBM has been simulating the whole brain one cell at a time. They started with cat brain simulation and have almost reached the whole brain simulation except it runs about 1542 times slower. This is a simulation of nearly 1.6 billion virtual neurons and 9 trillion synapses. The power consumption…
