Water. Not Just For Earthlings Anymore.

February 9, 2018

Water. Not Just For Earthlings Anymore.

With the help of HiRISE, a powerful camera aboard NASA’s Mars Reconnaissance Orbiter, scientists have found vast quantities subsurface ice reserves that astronauts could mine for drinking, growing crops, or converting into hydrogen for fuel.

“The deposits begin at depths as shallow as one meter and extend upwards of 100 meters into the planet. The researchers don’t estimate the quantity of ice present, but they do note that the amount of ice near the surface is likely more extensive than the few locations where it’s exposed. And what’s more, the ice looks pretty damn pure.”

Uncovering the Secrets of the Ocean Floor

November 1, 2017

Here’s another 20th Century “hidden figure”: Cartographer Marie Tharp. She processed the oceanographic data and produced the ocean floor maps proving Alfred Wegener‘s theory of continental drift. Helen Czerski explains it in this video from the Royal Institution of Great Britain, animated by Rosanna Wan.

GOP Science Gatekeeper: Earth is 9,000 years old

October 6, 2012

Representative Paul C. Broun, Jr., MD (R, GA-10) graduated from the University of Georgia and the Medical College of Georgia. He thinks that Planet Earth is only 9,000 years old and that Evolution and Embryology are “lies straight from the pit of Hell.” So much for higher education in the Peach State.

It gets worse. Congressman Broun, MD is a member of the House Science, Space, and Technology Committee. Perhaps he’s also medical adviser to fellow Science Committee member Todd Akin (R, MO-2), who believes victims of “legitimate rape” don’t get pregnant and that doctors are  giving abortions to women who aren’t pregnant.

Unsurprisingly, Congressmen Broun and Akin are both members of the House Tea Party Caucus.

Seismic Sisterhood: Boobquake

Iranian cleric Hojatoleslam Kazem Sedighi recently asserted that immodest female dress causes earthquakes. Purdue University student Jen McCreight disagreed, and urged other women to join her in a day of décolletée, a worldwide scientific experiment called Boobquake. On Monday they did, risking rumblings of Earth’s tectonic plates by ample exposure of cleavage.

Boobquake was a bust. Ayatollah 1, ladies 0.
