1. Scientists discover new material for gen-next data storage devices.
Traditional storage devices used polycarbonates (for CDs) and lasers to punch pits into them as data arrived. Each pit was read as a 0 and each ''flat'' as 1 by a photovoltaic cell that received reflected laser from pits. The current generated by the cell was used to provide input for audio and video devices. Rewritable CDs used metallic alloys that changed from amorphous to crystalline states under laser. These CDs and DVDs (and hard drives) used a different physical principle (modulating intermolecular forces that build lattice structure) than the one recently invented that uses electron disruption. With PEROVSKITE, we have a ferromagnetic - optical system of data transfer that is both compact and speedy. What would we call it? UltraDigital Disc (UD)?
2. Cheaper anti-stroke drug in the offing.single dose of the existing drugs used to normalise the physical condition of a stroke patient costs around Rs 66,000 while the latest drug -tenecteplase, is expected to cost just Rs 28,000,which helps defuse the blood clot in the brain and give a lease of life to the victims.

3. Baby boomer" generation is healthier. Owing to increased trend in obesity and diabetes, the rate of stroke has more than doubled among Generation X -- the people born between 1965 and 1974, a research has found.In contrast, the baby boomers -- born between 1945 and 1964 -- could be labelled as "stroke-healthiest generation", as they were found to have the lowest incidence of ischemic stroke. In fact, the 'baby boomers' were healthier than those born 20 years before as well as 20 years after them.
