Image Credit: Left/The Wire/Right/CNN A cockroach producing something resembling milk sounds like an unlikely subject for serious scientific research. Yet one species has developed a remarkably unusual way of nourishing its young. The Pacific beetle cockroach, Diploptera punctata, gives birth to live offspring rather than laying eggs, and its developing young feed on a milk-like…

NASA’s Hubble captures Saturn’s mysterious 10-sided atmospheric wave at its south pole (Image: X/ @NASAHubble) Saturn has revealed another strange feature in its atmosphere, and this time it is hiding around the planet’s south pole. New observations from NASA’s Hubble Space Telescope have captured a giant, evolving 10-sided atmospheric wave encircling the southern pole of…

Harvard neuroscientists have kept tiny clusters of human brain cells alive in laboratory dishes for more than five years, setting a new record that could change how researchers study the human brain. The peppercorn-sized brain organoids, each containing more than one million cells from the cerebral cortex, survived for roughly three times as long as…

PC: Harris & Ewing/Wikipedia In 1921, a 14-year-old boy working in an Idaho potato field imagined something almost impossible: sending pictures through the air in the same way radio carried sound. His name was Philo Farnsworth, and the vision he had would eventually lead him towards electronic television. Farnsworth believed pictures could be transmitted as…

The Burmese python has become a symbol of two completely different conservation battles. In Florida, wildlife managers search for and remove the giant snake because its introduced population is threatening native wildlife in the Everglades. Thousands of kilometres away in Bangladesh, researchers are putting radio transmitters on the same species to understand where it moves,…

​Representative Image of a caterpillar guarding wasp larvae and aggressively swinging its head at approaching predators (AI-generated image) A species of parasitic wasp has evolved one of the strangest survival strategies in the insect world, turning its caterpillar host into a living bodyguard for its own young. The wasp, from the genus Glyptapanteles, lays as…

One of the world’s most difficult plastics to recycle could soon have a far more valuable second life. Scientists at Virginia Tech have developed a chemical method that converts polyvinyl chloride, or PVC, into polyalphaolefin, an important material used in high-performance lubricants including engine oil. The approach tackles a longstanding problem with PVC, which is…

In 2023, researchers tested whether a building could be cooler than the air outside while still relying on natural ventilation. The experiment used two insulated boxes in California to study how radiative cooling, thermal mass and temperature-driven airflow could work together without fans or mechanical systems. The test box had an uninsulated aluminium roof covered…

Pine martens are making a remarkable return to south-west England after disappearing from Exmoor for more than a century, with conservationists capturing the first confirmed evidence that the reintroduced animals are breeding in the wild. A remote trail camera recorded a female pine marten with four kits on Exmoor, signalling that an ambitious effort to…

Gisat-1A is the programme’s second attempt, and its success finally gives India the capability that Gisat-1 was meant to establish. BENGALURU: When Isro’s GSLV-F17 lifted off from Sriharikota early Friday and successfully placed Gisat-1A or EOS-05 into its intended orbit, the mission did more than add another Earth observation satellite to India’s growing fleet.It ended…
