Quote of the day by Stephen Hawking Few questions have occupied the human mind for quite as long as why the universe exists, and whether human life actually has any real purpose. For centuries, people have approached these questions through religion, philosophy and science, often arriving at genuinely very different conclusions. Stephen Hawking, one of…

Since time immemorial, humans have been consuming food derived from the land, air and water. From vegetables and birds to even crabs, there is not much we have not used to survive on. But currently, people in New England are feasting on green crabs not to survive themselves but to help the native species subsist….

A fungus that infects house flies has evolved a remarkable way to send spores towards new hosts. Entomophthora muscae grows inside an infected fly and, after the insect dies, it produces microscopic stalks that emerge from its body. Each stalk forms a single spore at its tip. Instead of simply dropping away, the spore is…

In 2011, conservation teams set out on one of the biggest rat eradications ever on a tropical atoll, targeting an estimated 30,000 invasive rodents on Palmyra Atoll in the central Pacific. The goal was not just to remove a pest, but to restore an entire ecosystem that had been suppressed for more than a century….

In 2003, Nasa researchers reported that freshwater snails carried into orbit aboard the Space Shuttle had mated and reproduced during their mission, allowing their gravity-sensing organs to develop entirely under microgravity. According to the study published in PubMed, tittled ‘Otoliths developed in microgravity‘ formed part of the results of the STS-90 Neurolab Spacelab mission, a…

In 2005, five thick-toed geckos left Earth aboard the unmanned Russian spacecraft Foton-M2, embarking on a 16-day orbital flight with no access to food or water. The mission, a joint undertaking between Nasa and the Russian Academy of Sciences, was designed to test whether a reptile species could serve as a viable model for studying…

In January 1960, Nasa launched the rhesus monkey Miss Sam aboard a Little Joe rocket from Wallops Island, Virginia, to test the launch escape system built for Project Mercury. The flight was designed to confirm that the escape tower could pull the capsule clear of its booster during an abort, a safeguard critical to any…

The universe has fascinated humanity for centuries, but understanding it requires more than simply looking at the stars and planets. Galileo Galilei, one of history’s most influential astronomers and scientists, offered a powerful way of thinking about nature, arguing that the universe could be understood only by learning the language in which it was written….

Representative Image (AI-generated) What happens when waste from a coal-fired power station is placed beneath the sea? In 1989, researchers in the UK built an experimental artificial reef from 50 tons of stabilised coal-fired power station waste, and marine life began moving in almost immediately. The unusual experiment took place in Poole Bay, off the…

Engineers in Switzerland have worked out how to make miniature robots fly and steer without a single motor, magnet or battery on board. Researchers at the École Polytechnique Fédérale de Lausanne have built hollow structures that turn sound waves directly into thrust, drawing on Helmholtz resonance, the same physics behind the low hum produced by…
