NPL researchers have synthesised a security ink that emits intense red colour due to fluorescence when exposed to 254 nm wavelength UV and emits green colour due to phosphorescence soon after the UV source is turned off. A novel security ink that emits intense red colour when exposed to 254 nm wavelength UV and emits … Continue reading NPL synthesises novel security ink

Social factors too determine skin colour of Indians
Researchers from CCMB and other international institutions have found that socio-cultural factors had a bigger influence on skin colour variation in Indians than genetics (6.4%) and environmental factors (16%). While the SLC24A5 gene variant rs1426654-A is usually associated with lighter skin colour in most Indian populations, an intriguing pattern was seen in two specific populations studied. … Continue reading Social factors too determine skin colour of Indians
Less risk of skin cancer if exposed to UV radiation in the morning: Nobel Laureate Aziz Sancar
“If you really must go to a tanning booth, do it in the morning,” Aziz Sancar, from the University of North Carolina, Chapel Hill, U.S., who shared the Nobel Prize in Chemistry with two others — Tomas Lindahl of Francis Crick Institute and Clare Hall Laboratory, Hertfordshire, U.K. and Paul Modrich of Howard Hughes Medical … Continue reading Less risk of skin cancer if exposed to UV radiation in the morning: Nobel Laureate Aziz Sancar
