Diseased Brain Cells More Involved In ALS-associated Motor Neuron Death->

From feed by sdfeed
Researchers report for the first time that astrocytes -- the most abundant non-neuronal cells in the central nervous system, which carry a mutated gene known to cause some cases of amyotrophic lateral sclerosis (ALS/Lou Gehrig's disease) -- induce motor neuron death. This indicates that astrocytes may contribute to ALS by releasing a toxic factor that damages neurons.

Hypertension has always been associated with a higer risk for Ischemic Stroke (CVA). Whereas high cholesterol has been associated with corornary infarctions (because of artherscelerosis).

This article suggests that the underlying principle underlying both, is the same (clogging of arteries). Which for me as a med-student is pretty damn cool to read, since the hypertension-CVA connection is pretty poorly understood.

P.S. Artherosclerosis is caused by white bloodcells being absorbed into the blood wall and consequently absorbing cholesterol (thereby getting trapped). So it's actually very similar.

Man Arrested for Wireless Piggybacking 925

Sommelier writes "As reported by KATU in Portland, Oregon, a man was arrested for parking outside a coffee shop in nearby Vancouver, Washington, and using their open wireless AP — for three straight months. '"He doesn't buy anything," Manager Emily Pranger says about the man she ended up calling 911 about. "It's not right for him to come and use it."' Turns out the guy was a registered sex-offender as well." A different computer expert might have pointed out some ways to see if anyone is piggybacking on a wireless signal (many APs have a Web-interface client list), or even suggested something like NoCatAuth.

Harvard is only the second American university to announce its venture into the challenging, politically charged research field.'"

Google Releases Picasa for Linux 486

chrisd writes "Hi, everyone. Today I'm pleased to announce that we're making Picasa, our photo management application, available for Linux. This is a pre-beta labs release and since we're still learning on how to best make software for Linux, we're asking that you submit your bugs as you find them. Picasa for Linux uses Wine internally; this shows a bit in the interface, but it works even better than we had hoped. Download it and check it out! A list of supported distributions can be found in the FAQ. We hope our patches to Wine will help make it easier for everyone to run Windows apps on Linux and other Unix-like systems. Thanks to our pals at CodeWeavers who did much of the heavy lifting, and to Marcus Meissner, whose libgphoto support patch was a welcome surprise."

tinkertim writes "According to a Yahoo article, a school district in Libertyville, IL will be holding students accountable for illegal actions discussed in their MySpace blogs even if such actions in no way involved the school or another student. A spokesperson for the school district was quoted as saying: 'The concept that searching a blog site is an invasion of privacy is almost an oxymoron,' he said. 'It is called the World Wide Web.' Supposedly, no direct monitoring or snooping will be done unless the school receives a report from a concerned parent, community member or other student."

rcbutcher writes to tell us the Sydney Morning Herald is reporting that Google has just acquired the rights to a brand new text search algorithm invented by a University of NSW student. From the article: "Orion works as an add-on to existing search engines to improve the relevance of search and won praise from Microsoft founder Bill Gates last year. [...] Orion finds pages where the content is about a topic strongly related to the key word. It then returns a section of the page, and lists other topics related to the key word so the user can pick the most relevant."

No HD-DVD Movies Until April 243

from the very-expensive-paperweight dept.
Jed from Pan and Scan writes "It's official: when the first HD-DVD players are released on March 28, there will be no movie titles available in the new high-def format for at least another three weeks, and far fewer than initially announced. Warner, the only studio that was planning on having HD-DVD movies to accompany the format's much ballyhooed debut, will now release just three initial HD-DVD titles -- and not until April 18."
