| Microfluidic platform gives clear look at a crucial step in cancer metastasis Posted: 20 Sep 2013 08:14 AM PDT A microfluidic platform provides a high-resolution view of a crucial step in cancer metastasis. |
| Tiger genome sequenced: Tiger, lion and leopard genomes compared Posted: 20 Sep 2013 07:21 AM PDT Scientists have unraveled the first whole genome of a nine-year-old male Amur tiger (Panthera tigris altaica), and compared it with the genomes of other big cats including the white Bengal tiger, lions, and snow leopards. The genomic data from this study provides an invaluable resource for the future studies of big cats and their whole family's conservation. |
| Songbirds may have 'borrowed' DNA to fuel migration Posted: 20 Sep 2013 06:47 AM PDT A common songbird may have acquired genes from fellow migrating birds in order to travel greater distances, according to a new study. |
| Climate change: Polar bears change to diet with higher contaminant loads Posted: 20 Sep 2013 06:47 AM PDT Over the past 30 years, polar bears have increasingly exchanged ringed seal with harp seal and hooded seal in their diet. This change exposes the polar bear to more contaminants, according to a recent international study. |
| Antibacterial products fuel resistant bacteria in streams and rivers Posted: 19 Sep 2013 12:44 PM PDT Triclosan -- a synthetic antibacterial widely used in personal care products -- is fueling the development of resistant bacteria in streams and rivers. So reports a new paper that is the first to document triclosan resistance in a natural environment. |
