This rough diamond hints at oceans' worth of water inside Earth
It might be the ugliest diamond you'll ever see, but within this brown sliver of carbon is a gem of a find for a University of Alberta scientist working to unravel an ocean-sized mystery deep beneath the Earth.
Goldschmidt2014: Economy accommodation
For a very short time we are able to offer the chance for delegates to book accommodation in the Sacramento State dorm rooms. As well as the limited number of shared rooms there are a very few apartments with some self catering facilities available. The shared rooms are very basic with bathroom facilities down the hall but include the cost of breakfast and return buses to the conference center at key times. The deadline for booking this accommodation is April 8, all bookings must be finalized and paid by this date to secure your booking. No refunds will be possible. These rooms will sell out quickly, please book quickly via the Sacramento Visitors Bureau Web page.
Goldschmidt2014: Recruiting now — student helpers
One of the things which makes the Goldschmidt conference run so well each year is the input of the student helper team. We are now opening applications for student helpers at the 2014 conference in Sacramento, Calif. We are able to offer either 4 or 6 days employment at $100 a day ($50 per half day) and free registration to the conference. If you have already registered and paid this can be refunded. Applications must be made by filling in the form online by April 8, successful applicants will then be contacted. If you apply and are not accepted you will be allowed to register at the early rate for a further month after the deadline. For more information go to the student helpers page on the website.

More accurate data on thousands of years of climate change
Using a new, cutting-edge isotopic tool, researchers have reconstructed the temperature history of a climatically important region in the Pacific Ocean. The study analyzes how much temperatures have increased in the region near Indonesia, and how ocean temperatures affect nearby tropical glaciers in Papua New Guinea and Borneo. Researchers also evaluated the accuracy of existing climate model predictions for that region. The findings illustrate that the region is very sensitive to climate change and that it has warmed considerably over the last 20,000 years, since the last ice age.
Study: Oceans absorb and remove 15 percent of nitrogen oxide from air
A recent University of California San Diego study has found that besides regulating temperatures and weather patterns, oceans help cleanse the air as well. Researchers said that the surface of the sea has the ability to eliminate about 15 percent of the smog-forming nitrogen oxides (accumulated in polluted air) along the coast overnight.
Life's fuel cells
What is life? To prove that life exists, or did at one time, what signs should we be looking for?
Possible signs of life include a wide range of features on which we can focus. For example, cells walls or membranes made of simple carbohydrates encapsulate the most successful life-forms on our planet: bacteria. Fatty acids-chains of carbons, hydrogens and oxygens-are diagnostic of biosynthetic processes here on Earth. Certain proteins, such as DNA, can only arise from active biological processes. All of these processes and structures all have something in common, though: they use energy to renew themselves.
