New discoveries about the deep ocean's temperature variability and circulation system could help improve projections of future climate conditions. http://www.physorg.com/news179755953.html Space & Earth Fri, 11 Dec 2009 12:13:24 EST news179755953 The oceans could become the source of more of humanity's food if steps are taken to expand and improve marine aquaculture, according to a study published in the December 2009 issue of BioScience. http://www.physorg.com/news178892701.html Biology Tue, 01 Dec 2009 12:40:01 EST news178892701 (PhysOrg.com) -- Corals depends on the products of photosynthetic algae for most of their food, but they also eat tiny plankton. Now, for the first time, there is evidence of a coral eating jellyfish. http://www.physorg.com/news177666871.html Biology Tue, 17 Nov 2009 09:50:02 EST news177666871 The impact of airborne nitrogen released from the burning of fossil fuels and wide-spread use of fertilizers in agriculture is much greater that previously recognized and even extends to remote alpine lakes, according to a study published Nov. 6 in the journal Science. http://www.physorg.com/news176655560.html Space & Earth Thu, 05 Nov 2009 16:00:01 EST news176655560 (PhysOrg.com) -- Creatures large and small may play an important role in the stirring of ocean waters, according to a study released Wednesday that confirms a theory advanced by Charles Darwin. http://www.physorg.com/news168093166.html Space & Earth Wed, 29 Jul 2009 13:33:21 EST news168093166 Researchers have discovered where basking sharks - the world's second largest fish - hide out for half of every year, according to a report published today in Current Biology. The discovery revises scientists' understanding of the iconic species and highlights just how little we still know about even the largest of marine animals, the researchers said. http://www.physorg.com/news160921814.html Biology Thu, 07 May 2009 13:30:52 EST news160921814 Global warming could have chilling consequences for European livestock, warned Professor Peter Mertens from the Institute for Animal Health, at this week's meeting of the Society for General Microbiology in Harrogate. http://www.physorg.com/news157733711.html Biology Tue, 31 Mar 2009 15:55:43 EST news157733711 The origin of the neurotoxin azaspiracid has finally been identified after a search for more than a decade. The azaspiracid toxin group can cause severe poisoning in human consumers of mussels after being enriched in the shellfish tissues. The scientific periodical European Journal of Phycology reports in its current issue (Vol. 44/1: p. 63-79) that a tiny algal species, the dinoflagellate Azadinium spinosum, is responsible. http://www.physorg.com/news157129483.html Medicine & Health Tue, 24 Mar 2009 16:05:38 EST news157129483 Research published today reveals the major influence of fish on maintaining the delicate pH balance of our oceans, vital for the health of coral reefs and other marine life. http://www.physorg.com/news151251557.html Space & Earth Thu, 15 Jan 2009 14:19:17 EST news151251557 (PhysOrg.com) -- The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726
