Heat is animus. It was there at the birth of the universe, and its death will be the universe’s death. It is impossible to overstate its importance — both throughout human history and across modern technologies. The innovation of steam-powered pumps and engines in the 17th and 18th centuries, reaching the first of many summits…

Microalgae are “under-exploited crops” and do not compete with traditional food crops for space and resources. Representative image. | Photo Credit: Reuters CSIR-Indian Institute of Chemical Technology (IICT) scientists have spotlighted the potential of Chlorella Growth Factor (CGF), a protein-rich extract derived from the microalgae ‘Chlorella sorokiniana’, as an ideal ingredient for a wide range of…

Scientists have designed a magnetic resonance imaging (MRI) scanner that costs a fraction of existing machines, setting the stage for improving access to this widely used diagnostic tool. A MRI helps visualise minute details in the human body, with which doctors can diagnose disorders and select treatments for the brain, the heart, various cancers, and…

Visual: In 1829-1830, Russian mathematician Nikolai Lobachevsky worked out hyperbolic geometry. Name the Hungarian mathematician (above) who achieved the same feat in 1932. 1. Geometry is the study of some properties of space. Hyperbolic geometric is a form of this geometry created when the parallel postulate of _________ geometry is replaced. Fill in the blank…
Swimming through turbulent water is easier for schooling fish compared to solitary swimmers. The turbulent sheltering hypothesis, which suggests that traveling in schools allows fish to shield each other from disruptive water currents, thus making it easier to swim through rough waters. The researchers tested their hypothesis using giant danios (Devario aeqipinnatus), and observed these…
