God as a Drug: The Rise of American Megachurches

American megachurches use stagecraft, sensory pageantry, charismatic leadership and an upbeat, unchallenging vision of Christianity to provide their congregants with a powerful emotional religious experience, according to research from the University of Washington.

“The megachurches movement is one of the leading indicators of how American Christians exercise their faith these days, so therefore they should be understood,” said James Wellman, associate professor of American religion at the University of Washington. “And our study shows they’re doing a pretty effective job for their members, based on self-reports, contrary to public opinion that tends to pass them off as a type of consumerist religion. In fact, their members speak eloquently of their spiritual growth.” (more…)

Renowned expert Charles J. Vörösmarty addresses global water crisis

The world’s streams, rivers and lakes are under increasing stress because of human water management – and mismanagement – that threaten aquatic biodiversity and the water supply, Charles J. Vörösmarty said recently during the second annual John R. Mather Visiting Scholars Lecture.

Vörösmarty, professor of civil engineering with the City College of New York, presented “Global Water Crisis: The Slippery Slope” on May 3 at the University of Delaware’s Roselle Center for the Arts.

“The contemporary water system is really defined increasingly by the actions of humans,” he said. (more…)

NASA’s Spitzer Sees the Light of Alien ‘Super Earth’

PASADENA, Calif. – NASA’s Spitzer Space Telescope has detected light emanating from a “super-Earth” planet beyond our solar system for the first time. While the planet is not habitable, the detection is a historic step toward the eventual search for signs of life on other planets.

“Spitzer has amazed us yet again,” said Bill Danchi, Spitzer program scientist at NASA Headquarters in Washington. “The spacecraft is pioneering the study of atmospheres of distant planets and paving the way for NASA’s upcoming James Webb Space Telescope to apply a similar technique on potentially habitable planets.” (more…)

A NASA Weather ‘Eye in the Sky’ Marks 10 Years

For 10 years, it has silently swooped through space in its orbital perch 438 miles (705 kilometers) above Earth, its nearly 2,400 spectral “eyes” peering into Earth’s atmosphere, watching. But there’s nothing alien about NASA’s Atmospheric Infrared Sounder, or AIRS, instrument, a “monster” of weather and climate research that celebrates its 10th birthday in orbit May 4.

AIRS, built by BAE Systems, Boston, under the direction of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., is one of six instruments flying on NASA’s Aqua spacecraft as part of NASA’s Earth Observing System. AIRS, along with its partner microwave instrument, the Advanced Microwave Sounding Unit (AMSU-A), has faithfully measured our planet’s atmospheric temperature, water vapor, clouds and greenhouse gases with unprecedented accuracy and stability. Over the past decade, AIRS and AMSU-A have improved our understanding of Earth’s global water and energy cycles, climate change and trends and how Earth’s climate system is responding to increased greenhouse gases.

Cassini Finds Titan Lake is Like a Namibia Mudflat

A new study analyzing data from NASA’s Cassini spacecraft suggests that the lake, known as Ontario Lacus, behaves most similarly to what we call a salt pan on Earth.

A group led by Thomas Cornet of the Université de Nantes, France, a Cassini associate, found evidence for long-standing channels etched into the lake bed within the southern boundary of the depression. This suggests that Ontario Lacus, previously thought to be completely filled with liquid hydrocarbons, could actually be a depression that drains and refills from below, exposing liquid areas ringed by materials like saturated sand or mudflats.

Space Weather Forecast: Sunspotty, With an Increasing Chance of Solar Storms

The past few months have seen a spate of solar flares – bringing spectacular views of the northern lights as far south as Seattle – along with media speculation that the electrical activity could disrupt power grids, satellites or ground airplanes.

John Sahr, a UW professor of electrical engineering who studies the upper atmosphere, is the regional go-to guy for such questions. We found some time in Sahr’s busy schedule (he’s also the UW’s associate dean of undergraduate academic affairs and a part-time zombie hunter) to get his read on the space weather forecast. (more…)

Newfangled Space-Propulsion Technology Could Help Clean up Earth Orbit

Some of the most valuable “real estate” for humans isn’t on Earth at all but rather above the planet’s atmosphere, where all manner of human-made objects orbit. The problem is that those orbits are too crowded with dead satellites and debris, making new launches riskier.

Robert Winglee has spent years developing a magnetized ion plasma system to propel a spacecraft at ultra-high speeds, making it possible to travel to Mars and return to Earth in as little time as 90 days. The problem is that cost and other issues have dampened the desire to send astronauts to Mars or any other planet. (more…)

Climate Change Boosts Then Quickly Stunts Plants, Decade-long Study Shows

Global warming may initially make the grass greener, but not for long, according to new research results.

The findings, published this week in the journal Nature Climate Change, show that plants may thrive in the early stages of a warming environment but then begin to deteriorate quickly.

“We were really surprised by the pattern, where the initial boost in growth just went away,” said scientist Zhuoting Wu of Northern Arizona University (NAU), a lead author of the study. “As ecosystems adjusted, the responses changed.” (more…)
