GPS stations can detect clandestine nuclear tests

At the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) meeting this week, American researchers are unveiling a new tool for detecting illegal nuclear explosions: the Earth's global positioning system (GPS).

New biofuels processing method for mobile facilities

Chemical engineers at Purdue University have developed a new method to process agricultural waste and other biomass into biofuels, and they are proposing the creation of mobile processing plants that would rove the Midwest ...

Suzaku snaps first complete X-ray view of a galaxy cluster

The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. For the first time, Suzaku has detected X-ray-emitting gas at a cluster's outskirts, where ...

Study of vehicle emissons will aid urban sustainability efforts

Vehicles churn out about 28 percent of the carbon dioxide (CO2) generated from fossil fuels in the United States, and their contribution keeps climbing, particularly in urban areas. But planners and policymakers have lacked ...

3-D printed electrodes free the gas

Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy.

Planetary influences on young stellar disks

A newborn star typically has a disk of gas and dust from which planets develop as the dust grains collide, stick together and grow. Stars older than about five million years lack evidence for these disks, however, suggesting ...

CWRU awarded grant to build battery for smart grid, renewables

A Department of Energy agency that funds high-risk, high-payoff research, has awarded engineers at Case Western Reserve University $567,805 to develop a "rustbelt" battery with unprecedented flexibility and utility.

Production sites of stars are rare

Astronomers using the Nobeyama Radio Obeservatory (NRO) 45-meter telescope found that high-density gas, the material for stars, accounts for only 3 percent of the total mass of gas distributed in the Milky Way. This result ...

Star formation in the outskirts of galaxies

Star formation environments can be roughly grouped into three types, categorized by the density of their gas (or more precisely, the projected "surface" density of the gas, which is easier to determine than the conventional ...
