| Posted: 09 Jan 2015 07:10 AM PST A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip. Such arrays are crucial components of devices that use photons to perform quantum computations. |
| Map of mysterious molecules in our galaxy sheds new light on century-old puzzle Posted: 09 Jan 2015 06:35 AM PST Astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars. |
| More sun means fewer children, grandchildren, Norwegian study finds Posted: 09 Jan 2015 01:55 AM PST A new study shows that increased UV radiation can have an effect on human fertility over generations. On average, the lifespan of children born in years that had a great deal of solar activity was 5.2 years shorter than other children. Children who were born in years with lots of sunshine and who survived were also more likely to have fewer children, who in turn gave birth to fewer children than others. This finding shows that increased UV radiation during years of high solar activity had an effect across generations. |
