Why haven't these birds left yet? Thousands of migratory waders are still in Mumbai's wetlands

Thousands of migratory waders are still in Mumbai's wetlands, puzzling experts. Large flocks of sand plovers and other birds were recorded this weekend. Their prolonged stay has coincided with an extended summer and delayed monsoon. "By now they should have reached their breeding grounds," said ornithologist Raju Kasambe.

T-Rex had competition, and it was absolutely terrifying. But here's the twist

Giganotosaurus, a giant carnivore, once dominated South America before T-Rex ruled. This "giant southern lizard" lived roughly 99.6 million to 97 million years ago, while T-Rex appeared nearly 30 million years later. Though they never met, Giganotosaurus was a terrifying predator, rivaling T-Rex in size.

Earth dodged an asteroid by just 6 hours, crossing paths with a potential city-killer

Earth narrowly missed an asteroid, 4581 Asclepius, on March 22, 1989, by just six hours. This 1,000-foot space rock, detected nine days later, would have caused city-leveling devastation. The scare pushed for asteroid watch programs. "An impact would have released a devastating amount of energy," said Harvard professor Avi Loeb.

China's secretive Shenlong space plane releases mystery object in orbit. What is Beijing up to?

China's secretive Shenlong space plane released a mystery object in orbit on June 22, 2026. LeoLabs detected the object near Shenlong, assessing it was released from the Chinese craft. This reusable space plane, launched February 6, has sparked intrigue with its secretive missions and potential testing of advanced space capabilities.

Bird flocks soar through the sky like a liquid, atomic orchestra

NYU mathematicians explained how birds fly in flocks. Their flapping wings create "vortex wakes," guiding others. Birds move like an "atomic orchestra," with their positioning susceptible to disruptions but rapidly reconnecting. This study, published in Physical Review Fluids, uses a mathematical model to understand collective animal movement.

Did India's compliance push come at the cost of innovation?

India focused on compliance and formalisation for a cleaner economy. While countries like the US and Taiwan invested heavily in AI and semiconductors, India's push for innovation lagged. Many argue this focus on compliance may have cost India a share of global investment in strategic technologies.

Scientists discover kadedekedewa, a species of ‘walking’ shark in Papua New Guinea

Scientists discovered a new 'walking' shark species, Hemiscyllium dudgeonae, in Papua New Guinea. These sharks use fins like legs to move across reefs and can survive out of water for hours. Researchers found the species after noticing a unique colour pattern. The shark, named after Christine Dudgeon, may already face threats due to its small range.

New superconducting X-ray detector is up to 1,000 times more sensitive

A new superconducting X-ray detector is 100 to 1000 times more sensitive. Researchers plan to use it to study electronic properties of thin materials and diluted samples. The detector uses 248 sensors cooled to 25 milli-Kelvin. This advancement can reduce data collection times from hours to minutes.
