Creeping crinoids! Sea lilies crawl to escape predators, new video shows

...deos taken from a submersible research vessel at a depth of 430 meters (1410 feet) near Grand Bahama Island reveal that some sea lilies can creep along the ocean floor, apparently to escape from sea urchins that prey upon them. The video and related studies help paint a bigger picture of the evolution and ...

How 'Dirt' Could Educate The Immune System And Help Treat Asthma

...ld be more effective than injecting it at the same depth in either the Pacific Ocean or the Indian Ocean." Future climate change could affect both the uptake of carbon dioxide in the ocean basins and the ocean circulation patterns themselves, Jain said. As sea-surface temperatures increase, the density of...

Climate change will affect carbon sequestration in oceans, model shows

Future climate change could affect both the uptake of carbon dioxide in the ocean basins and the ocean circulation patterns themselves, Jain said.

World-first technology enables study of ancient bacteria

...emperatures (from an icy 2°C to over 100°C), great depth (several kilometres) and age (many millions of years) may contain most of the bacteria on Earth. Some of these bacteria produce methane that accumulates in "gas hydrates" ?a super concentrated methane ice that contains more carbon than all conventio...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...eleton, a finding that amazed scientists given the depth (about 4,500 meters) at which it was found. Research in the Southern Ocean is the most expensive in the world. The recent ANDEEP III expedition by icebreaker cost one Euro per second. The Antarctic Census will also harmonize with efforts by BirdLif...

Scientists discover unique microbe in California's largest lake

...is about 227 feet belowmean sea level, its maximum depth reaches 51 feet and its total volumeis about 7.5 million acre-feet. It was formed in the early 1900s, whenflow from the Colorado River was inadvertently directed to the SaltonBasin. Once the Army Corps of Engineers returned the river to itsnormal bed...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...on-polyA transcripts. This study focused on an in depth scan of 10 chromosomes; however, Affymetrix has developed tiling microarrays that cover all human chromosomes. GeneChip tiling microarrays have been used by Gingeras and his collaborators, as well as the NHGRI publicly funded ENCODE project, to study...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...g, making it easier to tease out what is living at depth in oceanic crust. The fluids that emerge may come in bursts when earthquakes occur; fluid flow may therefore repeat episodically over hundreds of thousands of years as abyssal hills are uplifted and spread away from the mid-ocean ridge crest.
