Lucrezia Terzi, a researcher at the Belgian Nuclear Research Centre (SCKCEN), has come up with a new way of predicting the monsoon at a science and technology conference organised in Vienna by the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO). The new method measures how much Beryllium-7 (an isotope of the element Beryllium) is present in the ..

L 98-59b, L 98-59c and L 98-59d are new planets discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS). Features of the New Planets While L 98-59b is around 80% Earth’s size, L 98-59c and L 98-59d are around 1.4 and 1.6 times the Earth’s size respectively. L 98-59 is the host star of the three ..
For the first time in Bangladesh, iron ore mine has been discovered at Isabpur village in Dinajpur. According to the Geological Survey of Bangladesh, a 400-foot thick iron layer was found 1,750 feet beneath the surface stretched over an area of 6-10 square kilometre. The percentage of iron in the mine was 65 which indicate ..
Murray Gell-Mann (89), a Jewish American physicist who theorized the existence of the quark and won a Nobel Prize for his method of classifying particles, has passed away in New Mexico on May 24, 2019. He transformed physics by devising a method for sorting subatomic particles into simple groups of eight, based on electric charge, ..
For the second year in a row, Iraq has become India’s top crude oil supplier in 2018-19 fiscal year and meet more than a fifth of the country’s oil needs. According to official data sourced from the Directorate General of Commercial Intelligence and Statistics, Iraq sold 46.61 million tonnes (mt) of crude oil to India ..
The researchers at Jamia Millia Islamia (New Delhi) have developed an ultrasensitive quantum thermometer using graphene quantum dots. The thermometer can precisely measure a wide range of temperature: 27 degree C to –196 degree C. It has high sensitivity when measuring different temperatures and can measure very minute (micro Kelvin) changes in temperature. It showed ..
