Rewriting the history of volcanic forcing during the past 2,000 years

Posted: 06 Jul 2014 12:33 PM PDT

Scientists have completed the most accurate and precise reconstruction to date of historic volcanic sulfate emissions in the Southern Hemisphere. The new record is derived from a large number of individual ice cores collected at locations across Antarctica and is the first annually resolved record extending through the Common Era.

Size of the human genome reduced to 19,000 genes

A new study updates the number of human genes to 19,000; 1,700 fewer than the genes in the most recent annotation, and well below the initial estimations of 100,000 genes. The work concludes that almost all of these genes have ancestors prior to the appearance of primates 50 million years ago.
