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.

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.

A viral rumour about total darkness on August 2, 2025, is creating panic. NASA clarifies no such event is scheduled. The rumour is a confusion with the August 2, 2027, total solar eclipse. This eclipse will be visible across Spain, North Africa, and the Middle East. It is expected to last over six minutes.
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.
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.
Germany explores bio-robotics for defence. Cyborg cockroaches are the new surveillance bots. Swarm Biotactics develops these insect-based robots. They carry cameras and sensors for real-time data. These robots can operate individually or in swarms. The aim is to gather intelligence from enemy areas. This reduces risk to human soldiers. Germany is embracing innovative military technology.
Brain scans in your 40s might reveal lifespan. Duke University research shows brain structure changes indicate biological aging. The DunedinPACE tool analyzes these changes. It helps predict cognitive decline and diseases. Early detection enables preventative care. This promotes longer, healthier lives. Brain imaging could become a routine health assessment. It helps in slowing age-related decline.
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.
Skywatchers in the Southern Hemisphere are gearing up for a partial solar eclipse on September 21, 2025. While India won't witness this event, viewers in New Zealand, eastern Australia, the Pacific Islands, and Antarctica will enjoy a crescent Sun. The eclipse, lasting over four hours, offers unique opportunities for scientific study and photography.
The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery -- and physicists are deeply divided about what is actually going on, a survey in the journal Nature said Wednesday. More than 1,100 of them responded to a survey conducted by the leading scientific journal Nature.
