When a coherent laser hits a surface, the laser light is diffracted in all directions. It is easy to take a laser pointer and do this experiment. The pattern that is emitted is a complex dotted pattern of bright and dark intensities. These intensities appear random but are actually a property of the material and…
In gene knockout studies, scientists delete or stop expression of one gene and then check to see if that gene is required. In these studies, if a gene is critical – say for cell division then cells do not divide and the gene is termed essential, the mutations in that gene would be termed lethal…
Many of the phone today, have accelerometer chips and they all seem to be sourced from a handful of manufacturers. Cell phone manufacturers also change their favorite chip and since each of them have slightly different characteristics, it is likely that they will give different results. Here is a list of Cell phone manufacturers, their…
It is postulated that the high nitrate content in beetroot is responsible for its ability to reduce the blood pressure. Circulation. 2012 June 12; 125(23): 2922–2932, Hypertension. 2008 March; 51(3): 784–790. The benefit of beetroot juice in reducing the blood pressure is worth cosidering.

Pharmaceutical companies are thought has rich giants with many resources available to them. However, they optimize manufacturing costs for small molecule chemical entities by outsourcing parts of the manufacturing, forming alliances with chemistry suppliers or basing their operations in low cost countries, like Puerto Rico. This works well for chemistry but for biological entity manufacturing,…
There are different kinds of accelerometers in phones. They seem to vary in characteristics in different phones. The accelerometer can be thought up as a device that measures gravity. The way to imagine an accelerometer is that of a ball hung on a spring that is attached to a solid surface (like the phone). As…
Innovation: Simplistically, innovation has been defined as a creative solution to the problem. However, innovation is 1) Identification of the problem and 2) Definition of the problem. The solution to the problem will occur once the first two steps are complete. An creative person has to be agnostic to the solution and technology since the…
In summer 2012, Krainc’s lab published a paper on the biochemical cause for the link between Gaucher’s disease and Parkinson’s. It is known in the literature that Gaucher’s disease families have a higher incidence of Parkinson’s disease, however the reason was unknown. Gaucher’s disease is an inherited disorder caused by the mutations of the GBA…
Aetna CEO, Mark Bertolini spoke at the 2012 4th annual mHealth summit and summarized his companies outlook to mHealth. He made some very interesting points. First of all, he recognized that the health system was expensive and that it was useful for a company like Aetna to participate in mobile health initiatives to reduce cost….
People spend a significant amount of time playing games and solving puzzles. It has always been argued that there must be some benefit that could be derived from the endeavors. Many man-hours, computer computation and power go into playing games. Obviously, they serve some physiological and psychological functions since so many people continue playing games….
