RoboBee gets crane fly-inspired legs for soft touchdowns
The Harvard RoboBee has long shown it can fly, dive, and hover like a real insect. But what good is the miracle of flight without a safe way to land?
The Ocean’s Secret Power Source — 2.5x Stronger Than Wind!
As the world races to move away from fossil fuels, new research has uncovered an extraordinary and nearly untapped energy source hiding in plain sight— ocean currents. According to a landmark study by researchers at Florida Atlantic University (FAU), ocean currents can generate 2.5 times more power than wind farms. Even more stunning is their near-constant energy flow, making them one of the most reliable clean energy sources on Earth.
This isn’t a distant dream or a futuristic concept—it’s science-backed, data-verified, and happening now.
Ocean currents are massive, steady flows of water driven by a mix of wind, the Earth’s rotation, temperature gradients, and salinity differences. Unlike wind or solar energy, which vary with weather and daylight, ocean currents flow predictably and consistently year-round.
Isro to launch 2 high-profile space missions: Indian astronaut going to ISS in May, NISAR sat liftoff in June
India’s space program is gaining momentum with astronaut Shubhanshu Shukla’s upcoming trip to the ISS as part of the Axiom-4 mission, marking the second Indian in space. Following this, the joint Indo-US NISAR satellite, a significant Earth observation project, is scheduled for launch in June. These missions highlight India’s growing capabilities and international collaborations in space exploration.
