| Posted: 30 Mar 2012 08:10 AM PDT Graphene could become the next big thing in the quest for smaller, less power-hungry electronics. Physicists are making discoveries that may advance electronic circuit technology.  |
| Scientists refine Earth's clock Posted: 29 Mar 2012 11:19 AM PDT New research has revealed that some events in Earth's history happened more recently than previously thought. Scientists have refined the data used to determine how much time has passed since a mineral or rock was formed. They report uranium isotopic composition of minerals, used to date major geological events, which are more accurate than previously published.  |
| Afghans share unique genetic heritage, DNA analysis shows Posted: 27 Mar 2012 07:00 PM PDT A study by the Genographic Project has found that the majority of all known ethnic Afghans share a unique genetic heritage derived from a common ancestral population that most likely emerged during the Neolithic revolution and the formation of early farming communities. Through detailed DNA analysis of samples from 27 provinces, the Genographic team found the inter-Afghan genetic variability to be mostly attributed to the formation of the first civilizations in the region during the Bronze Age.  |
