Mars: Meteorites yield clues to Red Planet's early atmosphere
Geologists analyzed 40 meteorites that fell to Earth from Mars to understand the history of the Martian atmosphere. Their new article shows the atmospheres of Mars and Earth diverged in important ways early in the solar system's 4.6 billion year evolution.
Goldschmidt2014: Mentor Program Update
Thank you to the 115 scientists and 193 students and early career scientists who have registered for the Goldschmidt2014 Mentor Program. The program has arranged many opportunities to interact including the Students Mixer (sponsored by the Moore Foundation), the Students Lounge (sponsored by NASA) and also during program Breakfasts (sponsored by Nu). Students and early career scientists may also have the opportunity to enjoy Wine Tasting (sponsored by the Moore Foundation) or a Wild Cats Baseball game (sponsored by Savillex). In addition, a number of insightful workshops, panels and town halls will provide relevant career and professional development information. The workshops topics include teaching (sponsors ASI-Resonetics and MAGNET), publishing (sponsor Elsevier), grant writing (sponsor Elementa), applying for jobs (sponsor ECORD), careers outside academia (sponsors CETAC and AIPG), and communicating science (sponsor Nature Communications). Town halls will meet with funding agencies (sponsor Stanford) and research programs like GEOTRACES (sponsor SCOR) and Critical Zone Observatories. Panels on dual career (UC Davis and UCSC) and a mini-workshop on integrating microbiology and geochemistry (Moore Foundation) will round out the program. Please visit the Goldschmidt2014 Mentor Program webpage for more details.

New study outlines 'water world' theory of life's origins
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin?
Warm US West, cold East: 4,000-year pattern; Global warming may bring more curvy jet streams during winter
Last winter’s curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A new study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth’s climate warms.
There's something ancient in the icebox: Three-million-year-old landscape beneath Greenland Ice Sheet
Scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. This finding provides strong evidence that the ice sheet has persisted much longer than previously known, enduring through many past periods of global warming.
IODP-ICDP Town Hall Meeting at EGU
The International Ocean Discovery Program (IODP) and International Continental Scientific Drilling Program (ICDP) are hosting a Town Hall Meeting on Tuesday, April 29 at the EGU General Assembly. This Town Hall meeting will be a valuable opportunity to share views on exciting challenges to take up for a better understanding of the Earth system and its changing environment.
ICDP Active Fault Zone Drilling Training Course
The International Continental Scientific Drilling Program (ICDP) will be holding an Active Fault Zone Drilling training course held from Oct. 6-10, 2014, in New Zealand. This training will touch upon relevant aspects of scientific drilling in active fault zones, including project planning and management, pre-site studies, drilling engineering, sample handling and storage, on-site analysis, downhole logging, permanent downhole seismic monitoring, and data management. The training course is recommended for graduate students and post-doctoral scientists involved in upcoming scientific drilling.
Uwingu PhD Student TravelGrants — deadline is April 30
Uwingu is announcing a solicitation for graduate students seeking travel grants; 10-15 awards are expected. Graduate students completing their PhD in 2014 and studying planetary science and/or exoplanets are eligible. Recipients must use the funds to present their research at a conference occurring by April 30, 2015. Selections will be made based on material provided by applicants in the form below. Applications are due no later than April 30, 11:59 p.m. PST. Contact firstname.lastname@example.org with questions. Award announcements are expected the week of 2 June.
AbGradCon abstract submission deadline — extended through April 24
The Astrobiology Graduate Conference (AbGradCon) held in Troy, N.Y., from July 27-31, provides a unique setting for astrobiologically-inclined graduate students and early career researchers to come together to share their research, collaborate, and network. AbGradCon 2014 is still considering applications for talks and travel funding through April 24. Applicants who submitted an abstract pre-deadline should expect to hear about the status of their presentation and travel funding within the next 3-4 weeks.
