Aging Reversed In Mice 554

Posted by samzenpus from the pressing-the-reset-button dept.
Hugh Pickens writes "The Guardian reports that scientists claim to be a step closer to reversing the aging process after experimental treatment developed by researchers at Harvard Medical School turned weak and feeble old mice into healthy animals by regenerating their aged bodies. 'What we saw in these animals was not a slowing down or stabilization of the aging process. We saw a dramatic reversal – and that was unexpected,' says Ronald DePinho, who led the study. The Harvard group focused on a process called telomere shortening where each time a cell divides, the telomeres are snipped shorter, until eventually they stop working and the cell dies or goes into a suspended state called 'senescence.' Researchers bred genetically manipulated mice that lacked an enzyme called telomerase that stops telomeres getting shorter causing the mice to age prematurely and suffer ailments, including a poor sense of smell, smaller brain size, infertility and damaged intestines and spleens. When the mice were given injections to reactivate the enzyme, it repaired the damaged tissues and reversed the signs of aging raising hope among scientists that it may be possible to achieve a similar feat in humans – or at least to slow down the aging process."

What To Load On a 4-Year-Old's Netbook? 742

Posted by samzenpus from the besides-plants-vs.-zombies dept.
nostrodecus writes "I have a nephew who is very young, but who has the techie gene — he found the Gruffalo on YouTube before anyone knew he could spell. Now he's almost 4, and I was thinking of giving him my netbook (Acer running XP), which I hardly use any more. So, of course, I will be deleting all the porn, but what should I load up on it? Are there tools/apps that I can load up on it to protect it and him from things he shouldn't see until college? Also, what apps or games could I load on it that a 4-year-old will get some use out of?"

Comment long hold out (Score 1) 286

we held out for a very long time, as a non-profit academic institute that didn't want to pay for certs...
The final straw was iPhones and the like, not only NOT talking to our self-signed IMAP-SSL server, but not even complaining why... (in fact, they say everything is fine, but never retrieve the mail...) The mail app doesn't even give you opportunity to accept the cert.

yeah, you can post your cert as a file on a webserver, and point safari to it, and explicitly add it as a profile... but that didn't seem to be a long term viable solution.
so, we finally purchased a wildcard cert. I hate paying the money, but it did fix our "problems".

Scientists Turn T-Shirts Into Body Armor 213

Posted by timothy from the will-stick-with-the-regular-kind-for-now dept.
separsons writes "Scientists at the University of South Carolina recently transformed ordinary T-shirts into bulletproof armor. By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."

Comment Good furniture costs money (Score 2, Insightful) 260

For those complaining about the price tag: good quality furniture made from solid wood costs real money.
I spent over $1000 on black walnut (some highly figured) for a 7 drawer chest on chest I built last summer.
Probably spent close to 100 hours on it too.
Depending on the wood, $10, $20 or even $50 a board foot ( 1 square foot of wood, 1 inch thick) is not unusual.

That said, if it's cheap wood, or plywood with hardwood veneer, you should not be spending the same amount. (unless the veneer is exceedingly rare).

I wouldn't be surprised if there was well over $1000 of wood and hardware in it. (also wouldn't be surprise if it was crap).

while this is certainly super-sized, this technology has been around for over a decade.
z-corp comes to mind (www.zcorp.com)

I saw them print out a rubber ball from elastic particles and flexible glue that actually bounced.
They kept the cost down early by using HP Deskjet hardware for the printing (just glue instead of ink).

cool stuff, but not new.
