How do you get plants to grow on Mars? The first step: relieve their anxiety. “According to NASA’s Vision for Space Exploration, humans will visit and explore Mars in the decades ahead. Inevitably, they’ll want to take plants with them. Plants provide food, oxygen, companionship and a patch of green far from home.

On Mars, plants would have to tolerate conditions that usually cause them a great deal of stress — severe cold, drought, low air pressure, soils that they didn’t evolve for. But plant physiologist Wendy Boss and microbiologist Amy Grunden of North Carolina State University believe they can develop plants that can live in these conditions. Their work is supported by the NASA Institute for Advanced Concepts.

Stress management is key: Oddly, there are already Earth creatures that thrive in Mars-like conditions. They’re not plants, though. They’re some of Earth’s earliest life forms–ancient microbes that live at the bottom of the ocean, or deep within Arctic ice. Boss and Grunden hope to produce Mars-friendly plants by borrowing genes from these extreme-loving microbes. And the first genes they’re taking are those that will strengthen the plants’ ability to deal with stress.” (NASA)

“The board of The American Society of Journalists and Authors (ASJA) has voted unanimously to not endorse an earlier decision to give a Conscience in Media award to jailed New York Times reporter Judith Miller, E&P has learned.

The group’s First Amendment committee had narrowly voted to give Miller the prize for her dedication to protecting sources, but the full board has now voted to not accept that decision, based on its opinion that her entire career, and even her current actions in the Plame/CIA leak case, cast doubt on her credentials for this award. ” (Editor and Publisher)

“When your source is the government, and the government is attempting to use you to target a whistleblower, the notion of shielding a source must be reconsidered. To apply standard practices regarding sources to hiding wrongdoing at the highest levels of government perverts the intent of the First Amendment.” [via rebecca blood via walker]
