TIFR desalinates seawater without using electricity

TIFR researchers have produced gold nanoparticles that can absorb sunlight over the entire visible region and even the near infrared light. They used such gold nanoparticles to absorb energy from sunlight to be able to desalinate seawater to produce drinking water. The gold nanoparticles can also be used for converting carbon dioxide to methane more … Continue reading TIFR desalinates seawater without using electricity

Antarctic ice reveals that fossil fuel extraction leaks more methane than thought

Hinrich Schaefer, National Institute of Water and AtmosphericThe fossil fuel industry is a larger contributor to atmospheric methane levels than previously thought, according to our research which shows that natural seepage of this potent greenhouse gas from oil and gas reservoirs is more modest than had been assumed. In our research, published in Nature on … Continue reading Antarctic ice reveals that fossil fuel extraction leaks more methane than thought

Editorial: Curiosity can’t kill life on Mars

As if the news on earth weren’t depressing enough, the latest dispatches from Mars are also gloomy. It turns out the red planet doesn’t have any atmospheric methane. Earthlings longing for inter-galactic companionship may have to set their sights elsewhere, for the gas is an important chemical signature of microbial activity. On earth, more than … Continue reading Editorial: Curiosity can’t kill life on Mars
