Scientists find brain region that helps you make up your mind Posted: 24 Nov 2013 05:05 PM PST One of the smallest parts of the brain is getting a second look after new research suggests it plays a crucial role in decision making.

Even if emissions stop, carbon dioxide could warm Earth for centuries Posted: 24 Nov 2013 05:05 PM PST Research suggests that even if carbon-dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years. Thus, it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Unusual greenhouse gases may have raised ancient Martian temperature Posted: 24 Nov 2013 05:05 PM PST Much like the Grand Canyon, Nanedi Valles snakes across the Martian surface suggesting that liquid water once crossed the landscape, according to a team of researchers who believe that molecular hydrogen made it warm enough for water to flow.

New genomic study provides a glimpse of how whales could adapt to ocean Posted: 24 Nov 2013 05:05 PM PST Researchers have completed the first in-depth minke whale genome sequence and their new findings shed light on how whales successfully adapted to ocean environment. The data yielded in this study will contribute to future studies of marine mammal diseases, conservation and evolution.

Study pinpoints cell type, brain region affected by gene mutations in autism Posted: 21 Nov 2013 09:59 AM PST A team has identified the disruption of a single type of cell -- in a particular brain region and at a particular time in brain development -- as a significant factor in the emergence of autism.
