Shocking Recipe for Making Killer Electrons

ScienceDaily (Mar. 11, 2010) — Take a bunch of fast-moving electrons, place them in orbit and then hit them with the shock waves from a solar storm. What do you get? Killer electrons. That's the shocking recipe revealed by ESA's Cluster mission.

World crude oil production may peak a decade earlier than some predict

The world's crude oil production, which comes from sources like this oil field, may peak a decade earlier than some scientists had predicted.

In a finding that may speed efforts to conserve oil and intensify the search for alternative fuel sources, scientists in Kuwait predict that world conventional crude oil production will peak in 2014 — [...]

End-of-Days Danger

If 2012 marks the start of the apocalypse, it will be our own fault, not nature’s or God's

Matt Collins
I don’t know how many e-mails I have received from children who are terrified that 2012 will somehow involve the end of life as we know it, all because of an unfounded fringe religious prophecy that has [...]

Invasion of the Drones: Unmanned Aircraft Take Off in Polar Exploration

Unmanned aircraft for polar science, such as the Meridian (shown during a test flight in Antarctica), are less expensive and safer to operate than ordinary airplanes.

Deforestation has revealed what could be a giant impact crater in Central Africa, scientists say.

The 36-46km-wide feature, identified in DR Congo, may be one of the largest such structures discovered in the last decade.
Italian researchers considered other origins for the ring, but say [...]

Ever-Changing Earth: How the Atmosphere Can Affect Planet’s Shape, Rotation, Gravitational Field

A new research project investigates how Earth's atmosphere affects our planet's shape, its rotation and its gravitational field.

ScienceDaily (Mar. 10, 2010) — Researchers at the Institute of Geodesy and Geophysics at Vienna University of Technology (TU) are investigating the effects of the Earth's atmosphere on our planet's shape, its rotation and its gravitational field.

ScienceDaily (Mar. 9, 2010) — The extremely strong earthquake that struck Chile Feb. 27 was a complicated rupture process, as scientists of the GFZ German Research Centre for Geosciences found out. Quakes [...]

Chile Earthquake Moved Entire City 10 Feet to the West

The magnitude 8.8 quake that struck near Maule, Chile, Feb. 27 moved the entire city of Concepcion 10 feet to the west.

Precise GPS measurements from before and after the earthquake, the fifth largest ever recorded by seismographs, show that the country’s capital, Santiago, moved 11 inches west. Even Buenos Aires, nearly 800 miles from the [...]

ScienceDaily (Mar. 8, 2010) — Some scientists will go anywhere for a proper test, including the mouth of a (sleeping) Hawaiian volcano. Dr. Inge Ten Kate, a University of Maryland Baltimore County research assistant, led an [...]

How Big Waves Go Rogue

An extra-tall wave struck a cruise ship off the Mediterranean coast of Spain this week, claiming two lives and injuring one person on board. Though the wave may not qualify as a “rogue wave,” it could have been created by the same forces.

To officially be rogue, the wave’s height must be more than double the [...]
