Antimatter observed to be falling down under influence of gravity

This handout illustration released by U.S. National Science Foundation on September 27, 2023, shows an anti-matter gravity experiment ALPHA-g at an undisclosed location. For the first time, scientists have observed antimatter particles — the mysteriously absent twins of the visible matter all around us — falling downwards due to the effect of gravity, Europe’s physics…

Tropical cyclones are intensifying more rapidly and frequently: INCOIS study

In a recent study, scientists have deduced that global warming has heightened cyclone intensity, multiple rapid intensifications leading to unpredictability of cyclone behaviour. File photo | Photo Credit: The Hindu A growing number of cyclones are experiencing multiple rapid intensification globally where a tropical cyclone intensifies dramatically in a short period like an increase in…

Traditional medicine provides health care to many around the globe – the WHO is trying to make it safer and more standardised

For approximately 80% of the world’s population, the first stop after catching a cold or breaking a bone isn’t the hospital — maybe because there isn’t one nearby, or they can’t afford it. Instead, the first step is consulting traditional medicine, which cultures around the world have been using for thousands of years. Traditional medicine encompasses the…

Muscle, wood, coal, oil: what earlier energy transitions tell us about renewables

In 2022, the burning of fossil fuels provided 82% of the world’s energy. In 2000, it was 87%. Even as renewables have undergone tremendous growth, they’ve been offset by increased demand for energy. That’s why the United Nations earlier this month released a global stocktake – an assessment on how the world is going in weaning itself off these energy-dense but…
