Growing up in Albany NY, I spent many summers in the 1950's and 1960's swimming in the Hudson River in an area about 14 miles south of the city. This was before cities had polution controls that are now in place along the river. Of course, the only problem was barge oil on the surface, which prohibited swimming now and then. But the tides carried it away in a couple of hours. I recall seeing many 1000's of people swimming in the Hudson. No health problems were ever identified.

His last chronometer keep better time than my old Accutron watch (circa 1960). Dava wrote a great book, and thanks for calling it to my attention again.
" I'd like to know if there's evidence that glial cells also have functional calcium uptake pumps and if their level of calcium fluctuates with blood level or remains constant..."
Glial cell (C6 glioma) calcium levels fluctuate with that of the external medium. Changes of a few mM produce cytosolic changes on the order of 10's of nM (J. Phyiol. several years ago). In vivo...who knows?
"While this is interesting news, it's certainly not true that we ever thought of glia as (in the words of the press release) "little more than glue." "......
Before 1950, some researchers confused the extracellular space in the brain with glial cells. The 'space' was actually cellular. Unfortunately, glial electrophysiological characteristics did not, do not, lend themselves to sustained, fundable study. i.e., where's that action potential? This glial cell calcium story, and the many other glial calcium studies, may help change some perceptions.
I agree with you: current thinking is astrocytes are good for you when you're developing your brain (providing pathways to guide neurons to 'final' destinations) but 'bad', if you're an adult who has a penetrating nerve-killing injury.
Social Security Numbers, ISPs, and Wireless Phones

The reviewers say that 30 government agencies keep track of you using social security (SS)numbers. Well, I had to fork over my SS number and a credit card number to my ISP to activate a $9 per month internet connection. I was also asked to fork over my SS number, a credit card number and my drivers license number to activate a $18 per month wireless phone plan. Curiously, I was able to buy the $180 wireless phone and an $800 PC with only a credit card number. Why is there an inverse relationship between cost of product and amount of personal information required to make the purchase?
If ABC is successful in preventing those terrible words from reaching our ears, where will censorship end? Censorship of words is just a stepping stone to other forms of censorship. Just think of the effects on American culture if TV networks refused to show people killing other people. The citizenery may view killing as repugnant. Police officers may be found guilty of killing citizens who show their wallets, 6 year old school children would have to vent their anger in other ways, patients released from psychiatric institutions and further medical care would have to use knives to kill other people, and, -horrors - the NRA would lose money. Politicians would go deeper in campaign debt. So, ABC, keep up the good work, continue to show those killings but keep those nast dirty words off the air.
According to the article, annual NAVY expenditures are 88 Billion. Fist Call lists Microsoft's annual revenues for 1999 at 21.8 Billion. While the NAVY may be Microsolft's biggest customer, it is unlikely that the ultimate barganing chip - Naval dissertion of Microsoft products - will deeply impact M$ in the eyes of Wall Street. Besides, M$ has significantly increased soft money "donations" to both political parties. So, I wish the Undersecretary good luck in his discussions with the M$ CEO. By summer, he will probably be working for Red Hat.

"James is an MFA student at Albany, N.Y.'s Rensselaer Polytechnic Institute. "
Last I checked, RPI is 8 miles north of Albany - across the wide reaches of the Hudson River. If your lost, its opposite Watervliet, NY.
