Analyses on a small pebble in south-west Egypt cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from. Researchers found exotic micro-mineral compounds in the ‘Hypatia’ stone that are not known to occur on Earth, elsewhere in our solar system, or in known meteorites or comets.

All-weather friendly cooling technology works without mechanical compressors or chemical refrigerants, and generates drinking water. A team of researchers from the National University of Singapore (NUS) has pioneered a new water-based air-conditioning system that cools air to as low as 18C without the use of energy-intensive compressors and environmentally harmful refrigerants. This game-changing technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for both indoor and outdoor use, the novel system is portable and it can also be customised for all types of weather conditions.
Engineers at Rice University’s Nanotechnology Enabled Water Treatment (NEWT) Center have found a catalyst that cleans toxic nitrates from drinking water by converting them into air and water. “Nitrates come mainly from agricultural runoff, which affects farming communities all over the world,” said Rice chemical engineer Michael Wong, the lead scientist on the study. “Nitrates are both an environmental problem and health problem because they’re toxic...Read More
Magenta panes also help plants save water. The first crops of tomatoes and cucumbers grown inside electricity-generating solar greenhouses were as healthy as those raised in conventional greenhouses, signaling that “smart” greenhouses hold great promise for dual-use farming and renewable electricity production...Read More
