Graph of the Day: The Cost of Production Of Oil

Estimates of the cost of production for oil production form various locations Image Credit: Oil Drum Whenever we speak of Peak Oil, the optimists point out that the technology for finding replacements will turn up as the prices rise; look at what has happened with the oil sands and with shale gas. But as this graph shows, each alternative just gets more expensive. … Read the full story on TreeHugger

The Week in TreeHugger: US Sues BP, New Car Smell Kills Cyclist and More (Slideshow)

The U.S. Department of Justice and the Environmental Protection Agency have filed suit against BP and eight other firms, asking that they be held liable for all clean up and damage costs associated with the Gulf Oil Spill. In other major green news this week, a “new car smell” is blamed for a hit-and-run on a cyclist in Vail; San Jose, California bans plastic shopping bags; NASA publishes two world maps showing that the planet is warming, the MacGyver approach to winter biking (zip ties!), and more in The Week in TreeHugger.

Barney Frank Speaks Out on Repeal of DADT — The Distraction is the Policy

Click here to view this media Barney Frank responded to critics of the repeal of DADT, calling it a distraction that could cost lives. As Frank Rightfully pointed out, “The maintenance of this policy is the distraction.” ‘Don’t ask, don’t tell’ passes handily in House of Representatives : Wednesday’s overwhelming vote for repeal had been expected. In May, the House, by a 40-vote margin, successfully attached repeal language to a broader defense bill that eventually cleared the chamber. Republicans, led by repeal critic Sen. John McCain of Arizona, have twice blocked that bill from heading to the Senate floor, most recently last week. But gay rights activists cheered the vote, saying the House is aligned with President Barack Obama, Defense Secretary Robert Gates, a majority of troops and most Americans, who all believe openly gay men and women should be allowed to put on the uniform. A Washington Post/ABC News poll out Wednesday found 77 percent of Americans favor allowing openly gay men and women to serve in the military. The results mirror previous polls that have shown overwhelming public support for ending the “don’t ask” law. “Momentum is solidly on the side of ending ‘don’t ask, don’t tell,’” Joe Solmonese, president of the Human Rights Campaign, said in a statement. “Now it is up to the Senate to consign this failed and discriminatory law to the dustbin of history.” It looks like they have the votes in the Senate if Reid doesn’t let the Republicans run out the clock.

Grolar Bears Just the Start? Melting Arctic Ice May Lead to More Hybrid Marine Mammals

In the case of disappearing arctic ice, the result is likely to be new hybrid species of marine animals, according to researchers published in the journal Nature . Grolar bears (part grizzly, part polar) are alrea… Read the full story on TreeHugger

Researchers find weak point in lithium-ion batteries, suggest better nanowires could be the answer

We’ve seen countless attempts to build a better lithium-ion battery , but there’s been far fewer research efforts devoted solely to figuring out why lithium-ion batteries don’t last longer. A team of scientists at the Pacific Northwest National Laboratory have been doing just that, however, and they’re now sharing some of their findings. The main culprit, they say, are the nano-sized wires made of bulk tin oxide used in the batteries, which can expand and deform considerably over time, eventually rendering the battery useless. What’s more, while the research was focused primarily on examining the cause of battery aging, the researchers do naturally have a few suggestions on how to improve them — namely, to replace those wires made of bulk tin oxide with finer tin oxide nanowires. As lead scientist Chongmin Wang explains, that would effectively amount to winding together “thinner wires rather than making one thick rope,” which is of course easier said than done. Head on past the break for the complete press release.

LaCie Float concept combines external HDD with trackpad, ingenuity with fantasy

How do you freshen up the typically unexciting external storage unit ? You slap a multitouch trackpad on the top of it, of course. And since you’re dreaming up wild concepts, make that top out of carbon fiber, provide a base made out of glass and insert some LEDs next to it to provide ambient illumination — with an integrated light sensor adjusting their brightness on the fly, obviously. Yes, Andr

Researchers Discover Caterpillar Whistles to Ward Off Birds

Image via Live Science video The walnut sphinx caterpillar has a trick up its sleeve — er, side — to keep birds from chomping on it. The clever bug can make an odd whistling sound, which startles birds enough that they usually just leave it alone. Researchers didn’t know how it managed to make this sound, so they set up cameras and began experimenting. The results are rather strange. … Read the full story on TreeHugger

The Washington Post simply cannot stop putting protesters of the removal of an ants-on-Jesus video on the front page of the Style section. Once again in Friday's paper, art critic Blake Gopnik is publicizing gay artist A.A. Bronson's request that his huge color photo of his skeletal lover Felix Partz in his bed hours after he died in 1994 be removed from the exhibit:
