IAF successfully test fires aerial version of BrahMos missile

Indian AirForce (IAF) has successfully test fired the BrahMos air version missile from its Su-30 MKI fighter aircraft.BrahMos missile is a 2.5 ton supersonic air to surface cruise missile with ranges of close to 300 km. A cruise missile is an unmanned self-propelled (till the time of impact) guided vehicle that sustains flight through aerodynamic… Continue reading IAF successfully test fires aerial version of BrahMos missile

ISRO launches radar imaging observation satellite RISAT-2B

Indian Space Research Organisation (ISRO) has successfully placed RISAT-2B (Radar Imaging Satellite-2B) into orbit 556 km above earth. The PSLV-C46 launcher carried the RISAT-2B. PSLV-C46 is the 14th flight of PSLV in ‘core-alone’ configuration i.e. without the use of solid strap-on motors. Polar Satellite Launch Vehicle is an expendable medium-lift launch vehicle designed and operated… Continue reading ISRO launches radar imaging observation satellite RISAT-2B

Are LEDs bad for your eyes? The jury is still out

French Agency for Food, Environmental and Occupational Health and Safety has claimed that the blue light in LED lightning can damage retina. LED lights are the latest technology in energy efficient lighting It has added that chronic exposure can accelerate ageing of retinal tissue and can cause degenerative diseases such as macular degeneration. However, experts… Continue reading Are LEDs bad for your eyes? The jury is still out

India adopts new standards for measuring units kilogram, kelvin, mole & ampere

India has adopted a global resolution to redefine four of the seven base units – kilogram, kelvin, mole and ampere. The changes have come into effect from May 20, 2019- World Metrology Day There are seven main units of measurement- a) metre for length, b) the kilogram for mass, c) the second for time, d)… Continue reading India adopts new standards for measuring units kilogram, kelvin, mole & ampere

Microscope to diagnose, treat diseases

Recently, scientists have developed a specialised microscope with the potential to diagnose diseases like skin cancer as well as perform precise surgery without making any incisions in the skin. The microscope will allow medical professionals to pinpoint the exact location of an abnormality, diagnose it and treat it instantly. This will allow scientists to scan… Continue reading Microscope to diagnose, treat diseases

Brain stimulation may help treat Alzheimer’s disease: Study

A study published in the journal has found that Magnetic stimulation of the brain under repetitive transcranial magnetic stimulation (rTMS) therapy improves working memory. This study may lead to a new therapy for individuals living with Alzheimer’s disease and other forms of dementia. Alzheimer’s disease is a chronic neurodegenerative disease. It is a type of… Continue reading Brain stimulation may help treat Alzheimer’s disease: Study
