Six scientists from India, Serbia, and the USA studied some of the brightest blazers called TeV (Tera-electron Volt) blazars and found that they stand out as a semblance of stability of brightness among the blazar family in the short duration.
Scientists in Bengaluru have found that UV and blue light combination reversibly switches the system between 3D and 1D photonic structure --- a novel interaction that can help make tunable and effective optical devices
Scientists at the National Aeronautics and Space Administration (NASA) say that this could be because the Earth's own atmosphere is lending a helping hand which, in other words, means that the Earth's atmosphere could be protecting the Moon as well.
'This discovery is a very important clue to how the dark ages of the Universe ended and there was light in the Universe'.
The single-step process developed by ARCI scientists comprises surface modification using a femtosecond laser (lasers emitting light pulses with durations between a few femtoseconds and hundreds of femtoseconds, i.e. 10-15 of a second), non-thermal, and ecofriendly.
