| NOAA lists ringed and bearded ice seal populations under the Endangered Species Act Posted: 30 Dec 2012 03:08 PM PST NOAA Fisheries has announced its final listing decision for four subspecies of ringed seals and two distinct population segments (DPSs) of bearded seals under the Endangered Species Act. Specifically, in line with the proposal, NOAA will list as threatened the Beringia and Okhotsk DPSs of bearded seals and the Arctic, Okhotsk, and Baltic subspecies of ringed seals. The Ladoga subspecies of ringed seals will be listed as endangered. The species that exist in U.S. waters (Arctic ringed seals and the Beringia DPS of bearded seals) are already protected under the Marine Mammal Protection Act. |
| Rare genetic faults identified in families with bowel cancer Posted: 30 Dec 2012 02:59 PM PST Rare DNA faults in two genes have been strongly linked to bowel cancer by researchers, who sequenced the genomes of people from families with a strong history of developing the disease. |
| Teenagers without Internet access at home are educationally disadvantaged, UK study suggests Posted: 30 Dec 2012 02:56 PM PST A major in-depth study examining how teenagers in the UK are using the internet and other mobile devices says the benefits of using such technologies far outweigh any perceived risks. |
| Scientists challenge current theories about natural habitats and species diversity Posted: 30 Dec 2012 11:30 AM PST How can a square meter of meadow contain tens of species of plants? And what factors determine the number of species that live in an ecosystem? This has been selected as one of the 25 most important unresolved questions in science, both for its importance in understanding nature and due to the value of natural ecosystems for humankind. The value of goods and services provided by natural ecosystems is estimated to exceed the GDP of our planet. |
