From EARTH Magazine, 05/15/15 -- The evolutionary age of grass has been hotly contested. Scientists have previously dated the earliest grasses to 55 million years ago; after the dinosaurs went extinct. Now, a new 100-million-year-old specimen of amber from Myanmar potentially pushes back grass evolution to the Late Cretaceous.

From EARTH Magazine, 04/28/15 -- The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) was formed in 1996 to monitor the planet for evidence of rogue nuclear weapons tests and explosions. In its May issue, EARTH Magazine spotlights how the CTBTO's worldwide monitoring network works and how it's using the network for civil and scientific applications beyond test monitoring.
From AGI, 04/17/2015 -- In celebration of Earth Science Week 2015, the American Geosciences Institute (AGI) is sponsoring three national contests honoring this year's theme, "Visualizing Earth Systems." This year's competitions will feature a photography contest, a visual arts contest, and an essay contest.
From EARTH Magazine, 04/13/2015 -- The massive 2011 Las Conchas Fire near Los Alamos, N.M., defied conventional fire science wisdom by racing downhill instead of uphill, and increasing intensity overnight. Now, EARTH Magazine brings you recent scientific analysis of the fire from a research team at Los Alamos National Lab.
From AGI, 03/31/2015 -- In a small lake along the Japanese coast, scientists have found evidence of turbulent waters centuries ago. These telltale signs of severe weather in the geologic record support the legend of the two kamikaze typhoons that protected Japan from Mongol invasion. EARTH Magazine follows University of Amherst geoscientist Kinuyo Kanamaru and his research team as the dig up history in search of signs of the storms.

From EARTH Magazine, March 18, 2015 - Did they survive? Since 1962, the fate of three inmates who broke out of the famous prison on Alcatraz Island in San Francisco Bay - carrying rubber rafts fashioned out of raincoats - has remained a mystery. From the U.S. Army Corps of Engineers to the hosts of the show "Mythbusters," many have tried to figure out what happened to the escapees. Now, EARTH Magazine brings you news of an effort led by a research team from Delft University in the Netherlands.
From EARTH Magazine, 03/04/2015 -- Children born during, and up to three years after, the devastating 1997-1998 El Niño event in northern Peru were found to be shorter than their peers in a new study covered in EARTH Magazine. The rising waters wiped out crops, drowned livestock, cut off bridges, and caused prolonged famine in many rural villages. Now, a new study that tracked long-term health impacts on children from the affected region has found that a decade later, the children continue to bear signs of the hardship endured early in their lives.
From EARTH Magazine, 02/26/15 -- After the Aug. 24, 2014, Napa Valley earthquake, movement continued along the principal fault to the north of the epicenter, according to a report released by the U.S. Geological Survey. Such "afterslip" is known from previous quakes, but this is the first time that strong afterslip has been observed in a populated residential community. While the majority of shaking on the main strand of the West Napa Fault Zone occurred in rural fields, approximately 20 homes were immediately affected.
