The Coevolution of Lice & Their Hosts 179

eldavojohn writes "It might be an uncomfortable subject but parasites are an interesting subject when it comes to evolution. Ever wonder if pocket gophers have lice? Well, they do. And most interesting of all is the evolution of these lice mirroring the evolution of gophers. To study the genes of lice may shed just as much light on evolutionary trees as studying the genes of the actual host the lice has evolved to. The most unsettling result from these studies is that human head lice and human pubic lice (crabs) vary so greatly that they are in two separate genera. There were similarities between our pubic lice and the lice found on gorillas. Scientists came to the conclusion, which they published today in BMC Biology, is just as striking as their earlier one about head lice. But it is hardly the same. We did not get pubic lice from other hominids. We got them from the ancestors of gorillas."

Submission + - Work expirience at Yahoo, Google and MS compared

dgtlmoon writes: "Fun and juicey short article on various work expiriences at Yahoo, MSN and Google as an internet, dont miss the fab graph at the bottom comparing them! And the classic interview questions — "Can you tell me what was the most difficult bug you faced while programming and what you did to resolve it?" isn't "My programs don't have bugs.""
Education

Submission + - High Tech School shut down

fermion writes: In the continuing story of corporations attempting to reform education, High Tech High in Redwood City has been shut down two years into a five year project, leaving bewildered parent and students behind. I guess this shows that educating the masses is not as simple as running a corporation. The threat of layoff cannot be used to bring unmotivated kids into line. The pipe dream of stock options cannot be used in place of genuine concern for the child. And the scores on standardized test cannot be fabricated as easily as the numbers in an SEC filing. As much as the Bill and Melinda Gates foundation wants to do good, they and others in the corporate world must discover that educating the populous is not a activity that will bend toward the standard corporate buzz words.

Submission + - Definitive answer to Fermi's Paradox

fiveniner writes: "I have written my definitive answer to Fermi's paradox, which I think is pretty more accurate and fun than the one shown one month ago in slashdot (http://science.slashdot.org/article.pl?sid=07/02/ 19/1515205) I really belive no one can argument on it. Here it goes: (link to my post: http://logforbuggymind.blogspot.com/2007/02/my-own -response-to-fermis-paradox.html ) So today I came with my own response to Fermi's paradox: As the technology and science knowledge of extraterrestrial civilizations advance, they feel eager to conquer the rest of the universe, but at some point in that way to the universe, they advance in science enough to know how does their brain work, and they realize that being eager to conquer the world is an impulse originated by their desire of power, which ultimately only gives pleasure because some neurotransmitters activate when "power" is achieved. So before they can even go and conquer the universe, they discover a drug which gives that same pleasure, but without conquering the universe, just eating a pill, so then they eat the pill, and dont want to conquer anything, because they are happy, and after that, they discover that disappearing is not such a bad option, so they decide to just disappear, so that's why there's no evidence of extraterrestrial life, it's better to have drugs and disappear. That's the ULTIMATE ANSWER to Life, the Universe and Everything thanks and best regards... (I love karma) elias"

Submission + - Dow Jones Plunge Fueled by Overwhelmed Computers

cloudscout writes: "The Dow Jones Industrial Average dropped over 400 points today. While there were various valid financial reasons for such a decline, some of the blame is being placed on computer systems that couldn't keep up with the abnormally high volume at the New York Stock Exchange and the resulting tremor as they switched over to a backup system. In other words, Dow Jones got Slashdotted."

jon_anderson_ca writes: The CBC reports:

Opposition parties banded together Tuesday to defeat a controversial Conservative proposal to extend two anti-terrorism measures contained in the Criminal Code.
It should be noted that neither of these measures, put in place in December 2001, were ever used.

Submission + - Argentina Storm Chase Expedition, Strongest Storms

Jeff Gammons writes: "A group of storm chasers from the United States are currently on a storm expedition in search of the worlds most intense lightning storms. The group is filming with the BBC for a upcoming documentary on National Geographic about these intense thunderstorm convergence area's in Argentina east of the Andes mountains. A NASA study identified these thunderstorms to be the most intense on earth. The strongest of the storms were found to occur east of the Andes Mountains in Argentina, where warm, humid air often collides with cooler, drier air, similar to storms that form east of the Rockies over the Plains in the United States.

Submission + - Stock Market Drop Blamed on Computer Error

WebHostingGuy writes: "Today the Dow Jones Industrial Index dropped a little over 3% in value. Stock market swings come and go but it is interesting that the sudden drop in the stock market is the result of a computer glitch. According to MSNBC, the computers running were not properly calculating trades. This led to the switch to a backup system which led to several seconds delay which impacted the Dow. Even now after the close of the market spokesmen for the NYSE Group Inc. could not confirm if all closing share prices were even valid."

daria42 writes: Ubuntu developers are finalising preparations for the release of the next version — dubbed Feisty Fawn — of the popular Linux distribution in mid-April. Overnight, Ubuntu developer Tollef Fog Heen announced Ubuntu's main software repository had been frozen — with no changes allowed to the code — as developers got ready to issue a fifth major test version ("Herd 5") of the next version of Ubuntu.
Security

Submission + - Laptop hibernation a security risk?

wally writes: "I was having a long think today when it popped into my mind, is hibernation on laptops a security risk?

My flow of thought went like this: if I stole a laptop knowing that it had encrypted home and root partitions (assuming a Unix-like OS), presumably if it has a separate swap partition, that'd contain an unencrypted snapshot of the system prior to hibernation.

Therefore, this RAM image is presumably exploitable. Booting a USB stick would allow closer examination, presumably I could do anything from reading an open sensitive OpenOffice document to inserting some exploitable code into the frozen kernel to do something nasty when the laptop is next booted.

Even if the system keeps a checksum somewhere hidden to ensure the integrity of the RAM image before loading, you could at the least extract some potentially sensitive details that would otherwise be safe?

What do other slashdotters think? Is this an easily exploitable threat that should see suspended RAM images encrypted?"

Submission + - VMware cries foul over Microsoft virtualisation

daria42 writes: The battle to control the virtualisation market has heated up with the launch of a white paper from VMware, which accuses Microsoft of anti-competitive practices. In language reminiscent of Microsoft's anti-trust battles in the US and its ongoing struggle with the European Union, VMware claimed that the software giant is "forcing [its] specifications and APIs on the industry", and "trying to restrict customers' flexibility and freedom to choose virtualisation software".

Submission + - Google Maps for the Brain

azonips writes: "From EurekAlert: Explore your brain, literally, at the largest online atlast of the brain! BrainMaps.org features the highest resolution whole-brain atlases ever constructed, with over 50 terabytes of brain image data directly accessible online. Users can explore the brains of humans and a variety of other species at an unprecedented level of detail, from a broad view of the brain to the fine details of nerves and connections. The website also includes a suite of free, downloadable tools for navigating and analyzing brain data. The high-resolution maps will enable researchers to use "virtual microscopy" to compare healthy brains with others, looking at structure, gene expression and the distribution of different proteins. They will enable better understanding of the organization of normal brains, and could help researchers in identifying fine morphological and chemical abnormalities underlying Alzheimer's, Parkinson's and other neurological diseases."
