Why Can’t They Just Stop the Leak?

I've been watching the Gulf Oil leak reports with a technical eye. They report that citizens have sent in over 100,000 suggestions on how to stop the leak, and more on how to clean it up. It's so simple: Just plug it. But I'd wager that the bulk of the suggestions are innumerate; they have no comprehension of the scale of the problem. As though the oil leak is like oil dripping from a car. This is a column of oil at least 2 feet wide and thousands of feet long already moving fast and under pressure. Stopping it is like stopping a freight train with the engines running. And doing it in one of the the harshest environments man has ever tried to work in on this planet. Many of the clean up suggestions, even the ones based on home testing, neglect to consider the scale. What might work in a sink is not practical to do to an ocean. BP has already consumed most of the world's available dispersant Corexit™ in an attempt to keep much of the oil suspended in the water. Sawdust? Hay? Hair? There isn't enough on all the heads in America. People, please do basic arithmetic before sending in suggestions. I heard one fairly clever suggestion from a brother-in-law: Freeze it with liquid nitrogen. My instincts first boggled at the immense cost of doing it. But then I considered and replied with a more convincing argument: Consider wrapping a fire hose in dry ice. All you get is a hole in the dry ice because any cooled material is moved down the pipe before it can slow the flow. I looked up some more details when I got home: Nitrogen won't even evaporate at the the pressure down by the wellhead. I think it's great that people are thinking. But it also shows the world how distinct thinking is from reasoning.

Hotels to guests: Go to sleep

In light of the importance of sleep, some hotels are telling their guests to stop the noise, stop the partying and go to sleep. It's about time, especially for those of us who check into hotels with the need to get some sleep in preparation for a meeting the next morning. The blaringly loud TV next door is my biggest nemesis.

Genomes, Souls, and Cousins

You may have heard the news. Humans and Neanderthals, apparently, had sex with each other at some time. Shocking, yes, I know. But the newish technology of sequencing genomes is turning up all sorts of fascinating (and potentially scandalous) data. In NatureNews Online you can read more about it.

The researchers arrived at that conclusion by studying genetic data from 1,983 individuals from 99 populations in Africa, Europe, Asia, Oceania and the Americas. Sarah Joyce, a doctoral student working with Long, analyzed 614 microsatellite positions, which are sections of the genome that can be used like fingerprints. She then created an evolutionary tree to explain the observed genetic variation in microsatellites. The best way to explain that variation was if there were two periods of interbreeding between humans and an archaic species, such as Homo neanderthalensis or H. heidelbergensis.

Speculation over Neanderthal/Human interaction has been ongoing for a long time. Some of the idiosyncrasies of the Basque language have even been hypothesized to have resulted from such interaction, as that region of Europe seems to have been the last place Neanderthal was known to live. That they shared space---and perhaps much more---with humans is, to say the least, and intriguing notion. [More . . . ]

What Obama is doing about the oil spill disaster

Rolling Stone has published a blistering expose on President Obama's failures regarding the Gulf Oil spill disaster. Yes, the Bush Administration was spectacularly at fault, but President Obama is carrying on Bush's tradition with exuberance:

For weeks, the administration had been insisting that BP alone was to blame for the catastrophic oil spill in the Gulf – and the ongoing failure to stop the massive leak. "They have the technical expertise to plug the hole," White House spokesman Robert Gibbs had said only six days earlier. "It is their responsibility." The president, Gibbs added, lacked the authority to play anything more than a supervisory role – a curious line of argument from an administration that has reserved the right to assassinate American citizens abroad and has nationalized much of the auto industry. "If BP is not accomplishing the task, can you just federalize it?" a reporter asked. "No," Gibbs replied.
At page 6 of the online article, Rolling Stone documents the absurd government dishonest downplaying of the extent of the damage. Further, the U.S. government continues to allow BP to operate in near secrecy. See also this excerpt from this excellent highly-detailed article in Rolling Stone:
On the campaign trail, Obama had stressed that offshore drilling "will not make a real dent in current gas prices or meet the long-term challenge of energy independence." But once in office, he bowed to the politics of "drill, baby, drill." Hoping to use oil as a bargaining chip to win votes for climate legislation in Congress, Obama unveiled an aggressive push for new offshore drilling in the Arctic, the Southeastern seaboard and new waters in the Gulf, closer to Florida than ever before. In doing so, he ignored his administration's top experts on ocean science, who warned that the offshore plan dramatically understated the risks of an oil spill and petitioned Salazar to exempt the Arctic from drilling until more scientific studies could be conducted.
