Stuart Haszeldine, a researcher at the University of Edinburgh (UK) has shown that sandstone rock formations under the seabed are capable of storing up to 150,000 million tonnes of CO2. According to the scientist, is the only option for storing carbon and achieve a reduction of 2 ° C in combating climate change.
 “This is a massive storage capacity could amount to hundreds of years of carbon from power plants,” said Stuart Haszeldine, a study author and researcher at the University of Edinburgh (United Kingdom). For the British geologist, another advantage of the underwater storage is that “it is safer and faster than underground storage.

 Researchers are about to undergo a fictional astronaut who has blood cells and simulated human tissue, an artificial solar flare. The way the radiation leaving the unfortunate volunteer for the first time reveal what level of threat posed by solar flares for astronauts traveling to the moon or Mars.
In 1972, the Apollo astronauts barely escaped a potential disaster. On 2 August of that year, a huge and ferocious sunspot appeared and began to erupt again and again for more than a week, producing a burst of solar proton radiation record-breaking.

 Researchers at Yale University (Connecticut) have shown that light can be used to move micro objects, such as driving nanomachines. The results could lead to opto-mechanical systems made from photonic circuits at the nanoscale. Although the force exerted by the photons is too small to be felt on a human scale, it can be recovered significantly by concentrating on small semiconductor circuits.

 Using software, a US-Chinese team has made a very simple system, based on metamaterials, producing an effect of invisibility in the microwave but this time over a wide frequency band. It is a kind of software to develop invisible devices have created: David R. Smith, from Duke University, Tai Jun Cui, University of the South East (Nanjing, China) and colleagues.
