The Keeling Curve Turns 50

The inception of the "Keeling Curve," a history of atmospheric carbon dioxide levels, marked a key moment in American science history. The record began in March, 1958 at a small observatory on the top of Hawaii's Mauna Loa.

Genome Variation at the Basepair Level - Prof. Aleks Milosavljevic

submitted by: ralanharris
Insights into cancer biology from the study of basepair-level changes in coding sequences. Genotyping vs. resequencing. Identifying cancer-related genes using association studies. Use of next-generation sequencing technologies to map chromosomal aberrations in cancer genomes. PCR-based resequencing vs. array-based enrichment. Using recurrence, pathway enrichment, and other signatures of positive selection to identify "driver" somatic mutations involved in cancer progression. Part of the...

Emperors of the Extreme

Emperor penguins can flourish in locales where few other animals roam. But scientists now wonder if they can adapt to a new threat: climate change.
