Georgia considers banning 'evolution'
The state's school superintendent has proposed striking the word evolution from Georgia's science curriculum and replacing it with the phrase "biological changes over time."
The change is included in more than 800 pages of draft revisions to Georgia's curriculum that have been posted by the Department of Education on its Web site. The middle and high school standards are expected to be voted on by the state Board of Education in May, after public feedback.
Superintendent Kathy Cox said the concept of evolution would still be taught under the proposal, but the word would not be used. The proposal would not require schools to buy new textbooks omitting the word evolution and would not prevent teachers from using it.
[...] Social conservatives who prefer religious creation to be taught instead of evolution criticized the proposal [along with educators and legislators].
"If you're teaching the concept without the word, what's the point?" said Rep. Bobby Franklin, a Republican. "It's stupid. It's like teaching gravity without using the word gravity."

So... what *is* a migraine, anyway?

Researchers have identified brain lesions in migraine victims, a finding that could indicate the severe headaches are a progressive brain-damaging disease in some cases, new research suggests.
The research, which has possible implications for treatment, involved 295 Dutch adults aged 30 to 60, some of whom had migraines with visual disturbances and some migraines without eye problems. They were compared to 140 similar people who were migraine-free.
Using magnetic resonance images, the researchers found that for patients with both migraines and visual problems the risk of cerebral infarction -- tissue which has died due to lack of oxygen when a blood clot blocks an artery -- was 13 times higher than the group which had no migraines at all.
The problem increased with the frequency of migraine attacks.
Patients with migraine but no eye trouble had more than seven times the risk that would normally be expected. The problem occurred in the cerebellar region of the brain, which controls motor motions.
