Transfusions Reverse Aging Effects On Hearts In Mice 130 130

symbolset writes "Research published yesterday in the journal Cell (abstract) by Richard Lee and Amy Wagers of Harvard has isolated GDF-11 as a negative regulator of age-associated cardiac hypertrophy. 'When the protein ... was injected into old mice, which develop thickened heart walls in a manner similar to aging humans, the hearts were reduced in size and thickness, resembling the healthy hearts of younger mice.' Through a type of transfusion called parabiotic or 'shared circulation' in mice — one old and sick, the other young and well — they managed to reverse this age-associated heart disease. From there, they isolated an active agent, GDF-11, present in the younger mouse but absent in the older, which reverses the condition when administered directly. They are also using the agent to restore other aged/diseased tissues and organs. Human applications are expected within six years. Since the basis for the treatment is ordinary sharing of blood between an older ill, and younger healthy patient, we can probably expect someone to start offering the transfusion treatment somewhere in the world, soon, to those with the means to find a young and healthy volunteer."

If you need a hand, ask on the netbsd-users mailing list (http://www.netbsd.org/cgi-bin/subscribe_list.pl?list=netbsd-users). Especially with the new release just being out there should be plenty of people willing to help with whatever issue you have.

(Since you've been running betas for a while you probably know about the mailing lists, so this is more of a PSA for anyone else)

Have you actually flown first class? I haven't, but I can tell you that even flying business class is a huge improvement over economy. Just getting on the plane is easier, with being able to use the priority lane for boarding, and sometimes even for security checks. Then there's the actual in-flight experience (more roomy and comfortable seat, more attention from the flight crew, drink what you want, etc...), but when things do go wrong the ground staff is actually happy to help you, and will do so even if there are a dozen economy class passengers that are clamoring for help. :P
Of course, it's way more expensive, but you get what you pay for.

Sure, some of the airline employees are hateful bastards, but I would be too if someone walked up to me and started yelling, so the "never become angry" applies regardless of what class you're flying.

Comment On the floor (Score 1) 549 549

Most flights I'm on I'm sitting on the floor b/c the plane has no seats. To fit 20+ skydivers into a Twin Otter you need to have at least some people sitting on the floor (and there aren't "seats" in the regular sense anyway). :)

I hate landing in planes; the number of times I've jumped out of the plane far outweighs the number of normal commercial flights I've taken.

Acceleration from a magnitude 5.7 earthquake can be "over 0.1g".

Acceleration from a car crash, even a minor one, can easily be _several_ g! It's not really comparable, unless the earthquake makes your rack fall over and hit the ground.

The reason why worry kills more people than work is that more people worry than work.
