Hadesarchaea: a New Archaeal Class of Cosmopolitan Deep Microbes
The deep biosphere encompasses a variety of ecosystems, from the marine subsurface to crevices in continental crust. These niches are characterized by different physical and chemical conditions, which in turn influence their microbial inhabitants. In a new paper in Nature Microbiology, a team of researchers including several DCO Deep Life scientists describes a new class of Archaea, which thrive in a variety of subsurface settings. The team, led by Brett Baker (University of Texas Austin, USA), used shotgun sequencing to obtain genomes from sediments from the hot springs of Yellowstone National Park and the White Oak River estuary. The Archaea they found are part of a class previously known as SAGMEG (South-African Gold Mine Miscellaneous Euchyarchaeal Group), and are very closely related to organisms found in the Lost City hydrothermal vent field and other deep locales.

Beyond Diamonds and Gems: The World's Rarest Minerals
Scientists have inventoried and categorized all of Earth's rare mineral species described to date, each sampled from five or fewer sites around the globe. Individually, several of the species have a known supply worldwide smaller than a sugar cube. These 2,550 minerals are far more rare than pricey diamonds and gems usually presented as tokens of love. But while their rarity would logically make them the most precious of minerals, many would not work in a Valentine's Day ring setting. Several are prone to melt, evaporate or dehydrate. And a few, vampire-like, gradually decompose on exposure to sunlight. Their greatest value to humanity lies in the tell-tale clues they offer about the sub-surface conditions and elements that created them, as well as insights into the planet's past biological upheavals. In fact, rare minerals represent Earth's truest distinction from all other planets, according to Robert Hazen (Carnegie Institution of Washington, USA) and Jesse Ausubel (The Rockefeller University, USA), authors of a paper in press to appear in the journal American Mineralogist.

New Updates from the Trail by Fire Expedition
Minding the Pampean Gap. Volcán Lastarria was a milestone for the Trail by Fire team because it marked the end of their travels in the Andean Central Volcanic Zone, the belt of active volcanoes that runs through southern Peru and northern Chile. Ahead of them was the long drive south across the Pampean Gap to reach the next target volcano. This gap reveals something fundamental about how volcanoes in the Andes work, and why the team is here in the first place, but it requires a bit of explanation. Read more...
Rapid Formation of Bubbles in Magma may Trigger Sudden Volcanic Eruptions
Some volcanoes erupt with little prior warning. Now, scientists have come up with an explanation behind these sudden eruptions that could change the way observers monitor active or dormant volcanoes. Previously, volcanologists thought eruptions were triggered by a build-up of pressure caused by the slow accumulation of bubbly, gas-saturated magma beneath volcanoes over tens to hundreds of years. But new research, published in Nature Geoscience, shows that some eruptions may be triggered within days to months by the rapid formation of gas bubbles in magma chambers very late in their lifetime.

New Company Launched to Commercialize Portable Gas Monitoring Instruments
Measuring carbon dioxide emissions from deep Earth is a complex and critically important challenge for the Deep Carbon Observatory. DCO convened a Gas Monitoring Workshop at Mt. Etna, Italy, in 2013, to identify and encourage the most promising technologies. As a result, Damien Weidmann (Rutherford Appleton Laboratory, UK) received DCO support to develop his team’s prototype Laser Isotope Ratio-meter (LIR) into a field instrument capable of real time in situ measurement of 12CO2/13CO2. Two years later, the LIR is the first product of MIRICO Ltd., a company established by Weidmann and colleagues. Read more...
The Carbon Mineral Challenge at the 2016 Tucson Gem and Mineral Show

DCO: Deep Life Cultivation Internship Program
The DCO Deep Life Community realizes that the majority of deep microbial life has been resistant to cultivation in the laboratory, which complicates the characterization of physiological characteristics of deep community members. However, recent studies using bioreactor-cultivation techniques, under high pressure and/or temperature, have resulted in successful enrichment of previously uncultivable archaeal and bacterial components that mediate biogeochemical carbon cycling in deep subsurface. In order to maintain and strengthen cultivation strategies in future deep life missions, the DLC will support early career researchers to visit some key laboratories (Inagaki - Kochi, Japan, Bartlett - La Jolla, USA, and others) to learn and practice newly developed cultivation and cultivation-dependent molecular/biogeochemical techniques using samples from the Deep Life Community’s field missions. Financial support includes $5,400 per person for travel and lodging costs and host lab research supply reimbursement. Interested applicants should send their CV, a brief one page statement of their cultivation plans, and a letter of support from their intended host to Fumio Inagaki and Douglas Bartlett.
Call for IODP Scientific Ocean Drilling Proposals
The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure, dynamics, and deep biosphere. The D/V JOIDES Resolution plans to operate 10 months per year in 2018 and 2019 under a long-term, global circumnavigation track based on proposal pressure. Future JR expeditions are projected to follow a path from the southwestern Pacific Ocean, through the Southern Ocean, and into the Atlantic Ocean for opportunities starting there in 2019. The JR is then expected to operate in the Atlantic, Mediterranean, Caribbean, and Gulf of Mexico starting in 2020. Although JR proposals for any region are welcomed, pre- and full proposals for these future operational areas are strongly encouraged. MSP expeditions are planned to operate once per year on average, and proposals for any ocean are welcomed. Chikyu operations will be project-based, and new proposals to use Chikyu in riser mode must be Complementary Project Proposals (with cost-sharing). IODP aims to foster joint projects with the International Continental Drilling Program (ICDP). IODP therefore also invite proposals that coordinate drilling on land and at sea. Deadline: 1 April 2016

16 February 2016: Earth's Rarest Minerals Give Diamonds A Run For Their Money
Chris D'Angelo for Huffington Post
Marilyn Monroe, who famously said, "Diamonds are a girl's best friend," probably hadn't heard of Sardinian ichnusaite. Ichnusaite, a pearly, colorless and brittle mineral, was discovered on the Italian island of Sardinia in 2013. Mineralogist Robert Hazen says that with only one known specimen, it's a true rarity. "If you wanted to give your fiancé a really rare ring, forget diamond. Give her Sardinian ichnusaite," said Hazen, co-author of a new paper categorizing Earth's rarest minerals.
16 February 2016: "Hellish" Ancient Organisms Found Living Inside Earth's Crust
Robin Andrews for IFLScience
Billions of years of evolution on Earth have produced “endless forms most beautiful,” as Darwin poetically noted. Some have evolved to live in “extreme” environments, such as deep sea hydrothermal vents and around the rims of lava lakes. Now, a new study published in Nature Microbiology reveals that extremely rare lifeforms have even managed to eke out a living inside the Earth’s crust itself.
16 February 2016: Hell (and Hadesarchaea) provides great research
Dave Armstrong for Earth Times
What the hell? In Hades, they have their own unique microflora. What hell holds for these organisms is largely unknown, except that they actually use carbon monoxide for energy. We have only just started looking at deep-sea and deep-in-the-ground life. These Hadesarchaea were first discovered in the US by Carl Woese, but now appear to be of even more immense significance.
13 February 2016: Earth's rarest minerals catalogued
Jonathan Amos for BBC
Scientists have categorised the Earth's rarest minerals. None of 2,500 species described is known from more than five locations, and for a few of them the total global supply could fit in a thimble. The researchers say it is important to hunt down these oddities because they contain fundamental information about the construction of our planet. Some will also undoubtedly have properties that are useful in technological applications. The list appears in a paper about to be published in the journal American Mineralogist. It is authored by Dr Robert Hazen, from the Carnegie Institution in Washington DC, and Prof Jesse Ausubel of The Rockefeller University, in New York.
12 February 2016: Geologists seeking help from rockhounds at gem show
Tom Beal for the Arizona Daily Star
The world’s collectors come to Tucson each February, seeking to add a gem, fossil or rock to their collections. Some geologists, meanwhile, are collecting rockhounds — enlisting those collectors in a challenge to complete the mathematical map of carbon-bearing minerals. The theoretical map of undiscovered minerals is based on work done at the University of Arizona, led by Robert Downs, to compile an open-access database of minerals.

1 February 2016: The 'alien life' deep underneath us: Researchers find first evidence of life in Earth's mantle under the Atlantic Ocean
Cheyenne Macdonald for the Daily Mail
Rock samples from an underwater mountain in the Atlantic Ocean could help to explain how early life formed on Earth, or on other planets. In a 47-day expedition, researchers collected rock samples that reveal signs of life in the mantle of the ocean’s crust. The mantle rocks, which were collected by an international team using seabed rock drills, could provide clues about the reactions that fuel life in areas without sunlight, and the behaviour of carbon in such a setting.
1 February 2016: Unprecedented: Expedition recovers mantle rocks with signs of life
An international team of scientists - recently returned from a 47-day research expedition to the mid-Atlantic - have collected an unprecedented sequence of rock samples from the shallow mantle of the ocean crust that bear signs of life, unique carbon cycling, and ocean crust movement. These unique samples were collected using unique seabed rock drills.

29 January 2016: New clues about how Earth got its moon
Amanda Barnett for CNN
It's the only world besides Earth that man has set foot on. But we still don't know exactly how it got there. Now, rocks brought back by the Apollo astronauts in the late '60s and early '70s are providing new clues about how Earth got its moon.
29 January 2016: Primeval Diamonds Reveal Snapshot of Early Earth's Tumultuous History
Tia Ghose for Live Science
Earth has gotten a number of face-lifts over its 4.4-billion-year history, but in one respect, the planet may look the same way it did when it was young, new research shows. Primeval diamonds from Witwatersrand, South Africa, contain evidence that early Earth replaced its rocky outer plates with deeper-dwelling mantle rock, said Katie Smart, a geologist at the University of the Witwatersrand and co-author of the new study.
