A recent study reveals a growing trend among teenagers using AI for companionship, advice, and emotional support, raising concerns about its impact on social development and mental health. Teens are increasingly turning to platforms like ChatGPT for personal guidance, sometimes even over real-life interactions.
A recent study, analyzing the Newall Boulder fragment, reinforces the theory that Stonehenge's builders transported massive stones from Wales using human effort and basic tools. Dismissing the glacial transport theory, geochemical evidence links the stones to quarries over 200 kilometers away. This highlights the ingenuity and endurance of Neolithic people in constructing the iconic monument.
A groundbreaking study reveals the alarming presence of 27 million tons of nanoplastics in the North Atlantic Ocean, posing significant threats to marine ecosystems and human health. These microscopic particles, originating from plastic breakdown and other sources, infiltrate the food chain and can penetrate tissues. Experts emphasize the urgent need to prevent further plastic pollution to mitigate this pervasive threat.
Asteroid 2025 OL1, about the size of a small plane, will safely pass Earth on July 30, 2025, at a distance of 1.29 million kilometers. NASA assures it poses no threat, but the event underscores the importance of monitoring near-Earth objects. ISRO is collaborating with global agencies to enhance detection and deflection capabilities, focusing on potential threats like asteroid Apophis.
Elon Musk says orbital refuelling is a hurdle for Starship. Two Starships will dock in space for fuel transfer. This is important for missions to Mars. Musk wants a reusable heat shield. He aims to cut spaceflight costs. The next Starship launch is in August. SpaceX wants to reshape space travel. Political tensions are rising for SpaceX.
In March 2025, a magnitude 7.7 earthquake struck central Myanmar, marking the strongest seismic event in over a century. A nearby CCTV camera captured the fault's rupture in real time, revealing a 2.5-meter ground slip in just 1.3 seconds. This unprecedented footage offers scientists a unique opportunity to study earthquake mechanics and improve future predictions.
The joint NASA-ISRO mission, NISAR, is set to launch, revolutionizing Earth observation with its advanced radar technology. Scanning the planet every 12 days, it will detect subtle changes, aiding in flood warnings, coastal erosion monitoring, and disaster response. This collaboration, fifty years after the SITE project, marks a significant advancement in Indo-US space cooperation, providing invaluable data to scientists worldwide.
A new study suggests the universe might collapse in 20 billion years. This challenges the idea of endless expansion. Scientists analyzed data from the Dark Energy Survey and Dark Energy Spectroscopic Instrument. They propose dark energy may not be constant. Gravity could eventually reverse expansion, leading to a Big Crunch. This is the opposite of the Big Bang.
NASA and ISRO are set to launch the NISAR satellite on July 30, 2025, aboard the GSLV-F16 rocket. This collaborative mission will employ advanced radar technology to monitor Earth's environmental changes, including land deformation, glacier movement, and ecosystem health. NISAR's data will benefit global climate research, disaster management, and agricultural planning.
