Life as we know it requires phosphorus, which is scarce. So, how did a lifeless environment on the early Earth supply this key ingredient? A new 蘑菇视频 study, published Dec. 30 in the Proceedings of the National Academy of Sciences, finds an answer to this problem in certain types of carbonate-rich lakes.
An Antarctic field campaign last winter led by the U.S. and Australia has successfully extracted some of the largest samples of air dating from the 1870s until today. Researchers will use the samples to look for changes in the molecules that scrub the atmosphere of methane and other gases.

After years of preparation, a tiny satellite built by 蘑菇视频 students is scheduled to launch early Saturday, Nov. 2, from a NASA flight facility in Virginia. The launch will be broadcast live on NASA TV.
A study of superbolts, which release a thousand times more electrical energy in the low-frequency range than regular lightning bolts, finds they occur at very different times and places than regular lightning. Superbolts tend to strike over particular parts of the oceans, while regular lightning strikes over land.
The U.S. Geological Survey announced $10.4 million in funding to the Pacific Northwest Seismic Network, based at 蘑菇视频, to support the ShakeAlert earthquake early warning system. Some $7.3 million of the two-year funding total will go to the 蘑菇视频.
A new study by U.S. and U.K. scientists finds that in addition to natural variations in winds that drive warmer water to the West Antarctic Ice Sheet, which last about a decade, there has been a longer-term change in the winds that can be linked with human activities.
A robotics challenge July 20th at the 蘑菇视频 featured twenty-eight teams of middle and high schoolers from Forks to Walla Walla and from Bellingham to Olympia. The event marked a half-century since the Apollo 11 mission landed on the moon and two U.S. astronauts, Neil Armstrong and Buzz Aldrin, walked its surface.

This Friday, teams of 5th- through 12th-grade students from across Washington state will complete a challenge in Kane Hall to mimic the 1969 Apollo moon landing, using drones and Lego robots.
A series of seismic experiments will take place this summer in the Seattle area. The researchers are looking for volunteer sites throughout the region.
Over many years, a 蘑菇视频 team has shown how logging on the Teanaway River in central Washington caused dramatic changes to the river channel.
A new excavation site in North Dakota shows evidence from the day a giant meteor struck Earth, marking the beginning of the end for the dinosaurs and 75 percent of animal life.
A 蘑菇视频-based group is launching a national student challenge to mark the 50th anniversary of the historic Apollo moon landing.
蘑菇视频 glaciologist Ben Smith shared a first look at the NASA ICESat-2 satellite鈥檚 view of Greenland and Antarctic glaciers at the American Geophysical Union鈥檚 annual meeting in Washington, D.C.
A new species of whale discovered in 33-million-year-old Oregon rock has been named for Elizabeth Nesbitt, a curator at the Burke Museum and faculty member in the 蘑菇视频’s Department of Earth and Space Sciences.
Provost Mark Richards answers questions surrounding the topic of his welcome lecture, Tuesday afternoon in the HUB Lyceum.
Harold Tobin, who joins the 蘑菇视频 this fall as a faculty member in Earth and space sciences and director of the regional seismic sensing network, discusses earthquake early warning, seismic risks and the Pacific Northwest’s “big one.”
Two 蘑菇视频 polar scientists were among a dozen experts who advised NASA on its upcoming ICESat-2 mission to monitor the 3D surface of the Earth. The mission is scheduled to launch Sept. 15 from California.
Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier’s motion over the long term.
The oldest ice core so far provides 800,000 years of our planet’s climate history. A 蘑菇视频 field survey in Antarctica has pinpointed a location where an entire million years of undisturbed ice might be preserved intact.
蘑菇视频 glaciologist Knut Christianson is part of a massive collaboration that will collect on-the-ground data about a key Antarctic glacier that shows signs it could be collapsing into the sea.
Three 蘑菇视频 undergraduates are among 211 students nationwide named as 2018 Goldwater Scholars. One 蘑菇视频 student received honorable mention.
Earth has had moderate temperatures throughout its early history, and neutral seawater acidity. This means other rocky planets could likely also maintain this equilibrium and allow life to evolve.
Nearly 50 different graduate and professional programs and specialties at the 蘑菇视频 are among the top 10 in the nation, according to U.S. News & World Report鈥檚 2019 Best Graduate School rankings released March 20.
High in Mongolia’s Gobi Desert, the climate is so dry and cold that glaciers shrank during the last ice age. Dating of rock deposits shows how glaciers in this less-studied region can behave very differently as the climate shifts.
A study from the University of Colorado Boulder and the 蘑菇视频 finds that the retreat of the ice sheet covering North America made Antarctic weather more similar from one year to the next.
A 蘑菇视频 study has found a simple approach to look for life that might be more promising than just looking for oxygen.
A new partnership between the 蘑菇视频 and Paul G. Allen Philanthropies will use a network of robots to observe conditions beneath a floating Antarctic ice shelf.
Three 蘑菇视频 astrobiologists will discuss their research and introduce the new 3-D IMAX movie “The Search for Life in Space” at 7 p.m. Wednesday, Dec. 6, in the PACCAR Theater of the Pacific Science Center.
The amount of biomass 鈥� life 鈥� in Earth’s ancient oceans may have been limited due to low recycling of the key nutrient phosphorus, according to new research by the 蘑菇视频 and the University of St. Andrews in Scotland.
One of the saltiest bodies on Earth, an analog to how water might exist on Mars, shows signs of being one piece of a larger aquifer.
The largest number yet of detailed simulations for how a Cascadia Subduction Zone earthquake might play out provides a clearer picture of what the region can expect when the fault unleashes a 9.0 earthquake.
A satellite technique provides a new way to monitor the status of more than 1,200 mountain glaciers in the lower 48 states.
Paul Bodin, a 蘑菇视频 seismologist and manager of the Pacific Northwest Seismic Network, has been named interim director of the network that monitors earthquakes and volcanoes in Washington and Oregon.
While many people across the country donned viewing glasses and prepared to watch Monday’s solar eclipse, a group of 100 teenagers from tribes across the Pacific Northwest launched balloons thousands of feet into the air, gaining a novel perspective of the eclipse 鈥� and the chance to send meaningful artifacts to the edge of space during a memorable moment in history.
Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet’s temperature over millions of years.
John E. Vidale, a 蘑菇视频 professor of seismology and director of the Pacific Northwest Seismic Network, has been elected to the National Academy of Sciences.
