Geologist says there's no need to fight over mineral resources
It's easy to be a pessimist in a world full of calamities. But for those worried about the continuing availability of natural resources, data from the ocean makes a good case for optimism, says economic geologist Lawrence ...
Is the Pacific Ocean's chemistry killing sea life?
The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, Washington's shellfish growers largely shrugged it off.
Computer simulations indicate calcium carbonate has a dense liquid phase (w/ Video)
Computer simulations conducted at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) could help scientists make sense of a recently observed and puzzling wrinkle in one of ...
Acid test: Study reveals both losers and winners of CO2-induced ocean acidification
(PhysOrg.com) -- As the world’s seawater becomes more acidic due to rising atmospheric carbon dioxide, some shelled marine creatures may actually become bigger and stronger, according to a new study.
Scientists probe Canadian sulfide ore to confirm microbial activity in seawater 2.7 billion years ago
An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively ...
Mars was Wet, but was it Warm?
Mars is frozen today, but when it was young there may have been liquid water on its surface. What does the latest evidence indicate about the ancient martian climate? Understanding the past environment of ...

Scientists locate apparent hydrothermal vents off Antarctica
Scientists at Columbia University's Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn ...
Climate change in Kuwait Bay
Since 1985, seawater temperature in Kuwait Bay, northern Arabian Gulf, has increased on average 0.6°C per decade. This is about three times faster than the global average rate reported by the Intergovernmental ...
Salt power: Watt's next in rechargeable batteries?
Reza Shahbazian-Yassar thinks sodium might be the next big thing in rechargeable batteries.
Signs point to sponges as earliest animal life
(PhysOrg.com) -- Even Charles Darwin was puzzled by the apparently sudden appearance in the fossil record of a great variety of multicellular creatures — a rapid blossoming known as the Cambrian explosion. ...
Hot rocks fire up energy from the depths
(PhysOrg.com) -- Scientists at Newcastle University have completed the first phase of a giant central heating system that will harness heat from deep underground.
World's oceans get an acid bath
Among the repercussions of global climate change, the effect of ocean acidification on marine life is one of the least-understood variables.
Fukushima nuke pollution in sea 'was world's worst'
France's nuclear monitor said on Thursday that the amount of caesium 137 that leaked into the Pacific from the Fukushima disaster was the greatest single nuclear contamination of the sea ever seen.
