Nanomaterials: What are the environmental and health risks? Venice, Italy (SPX) Mar 06, 2018 From nanoscale silver to titanium dioxide for air purification, the use of nanomaterials of high commercial relevance proves to have clear benefits as it attracts investments, and raises concerns. 'Nano' sized materials (a nanometre is one millionth of a millimetre) could pose environmental and health risks under certain conditions. The uncertainties and insufficient scientific knowledge could slow down innovation and economic growth. How do we evaluate these risks and take the appropriate prevent ... read more |

Unlocking the secrets of the universe Tempe AZ (SPX) Mar 01, 2018
Long ago, about 400,000 years after the beginning of the universe (the Big Bang), the universe was dark. There were no stars or galaxies, and the universe was filled primarily with neutral hydrogen gas.
Then, for the next 50-100 million years, gravity slowly pulled the densest regions of gas together until ultimately the gas collapsed in some places to form the first stars.
