The sun issues a continuous stream of charged particles called the solar wind, which create a vast region around our solar system called the heliosphere. This region acts like a protective

[ad_1] Geoengineering is a hotly contested topic both among scientists and policymakers. While some call it an innovative solution that could buy a warming world some time, others believe it’s a reckless cop out that could further environmental exploitation. A new study, led by University of Exeter geoscience professor Martin Siegert, has now tipped the

[ad_1] The Greek philosopher Pythagoras explained the universe using the ‘Music of the Spheres’, orbs on which celestial objects moved in consonance with mathematical harmonies to create a cosmic symphony of sorts. Today, astronomers are treated to this ethereal ‘music’ every time they eavesdrop on the universe using radio telescopes to unravel its mysteries. The

[ad_1] Maize (Zea mays) has long stood at the intersection of human culture and the natural world. Originating from teosinte, a wild grass domesticated in Mesoamerica over 9,000 years ago, it was gradually transformed through centuries of selective breeding by Indigenous farmers. From a small-eared plant with a handful of hard kernels, maize thus evolved

For a long time, astronomy was almost entirely based on light, i.e. what we see through telescopes, across the spectrum from

[ad_1] Battery energy storage systems are key to balancing India’s growing renewable power. But limited manufacturing, high costs, and lithium import dependence raise big questions about India’s clean energy future. [ad_2] Source link

[ad_1] Between 2000 and 2015, the world’s fight against malaria made remarkable progress, with millions of lives saved through better prevention, diagnosis, and treatment. Of late, however, that momentum has slowed. In 2023 alone, malaria claimed nearly 6 lakh lives, with 95% of those deaths occurring in the African region. India has made dramatic progress too,

[ad_1] An acronym that stayed… Late in the 1940s, following the end of World War II, a small number of visionary scientists – including Danish physicists Niels Bohr and French physicist Louis de Broglie – became aware of the need for Europe to have a world-class physics research centre. By December 1951, with some assistance
