While medical marijuana has been promoted as a treatment for a variety of ailments, finding anyone who promotes it as a memory boost is rare. Yet a German-Israeli team of researchers has just published a paper suggesting that at least in aging mice, marijuana does just that. Both in terms of mental performance and gene activity in the brain, treatment with pot's active ingredient seems to restore older mice to a state resembling that of youth. But getting to that point took a month of treatments at levels that might affect mental performance as well.
[...] The researchers performed the tests with mice in different age groups: two months, 12 months, and 18 months. That's roughly young, middle-aged, and elderly for mice. The mice were subjected to tests of learning and memory. In both tests, the animals that had received THC showed no decline with age. All the treated mice consistently tested as if they were two months old.
Something similar was found when the authors looked at gene activity in the brain. As mice age, a variety of genes see their activity go up or down; a number of the genes here have been associated with aging's effects on the brain in earlier studies. After four weeks of THC, however, these genes ended up being active at levels similar to those seen in two-month-old mice.
The study found that mouse brains age more quickly when they do not have cannabinoid receptors in the brain, that the drop in cannabanoid production quantity within the brain rapidly increases brain aging, and that THC which mimics naturally produced cannabanoids can fill in this production gap. Mice in the treatment group had more neuron connections than the control group, implying their ability to learn has been increased as well. The original paper is paywalled but ScienceDaily has a good article about it. Before you start lobbying your manager to hot-box the break room in the office it's worth nothing that when THC is given to young rats they become lazy. Surprising no-one, this happens in humans too (but only when they're high). Original papers (no paywalls).
I guess it's okay for Grammy and Grampa to share a daily roach in their golden years?

Is it known that a bunch of links on SN are broken (never respond or lead to errors)?
For example, the Finances page: https://wiki.soylentnews.org/wiki/Finances [soylentnews.org]
Or the "Who's who" page: https://wiki.soylentnews.org/wiki/WhosWho [soylentnews.org]

Both work for me, so maybe your DNS is wrong on wiki.soylentnews.org ?

Hmm, I get the same IP address. But things are happening right now, because about half an hour ago I got "nothing for you to see here, move along" messages, trying to connect with "&from=rss" in the URL. And all the pages looked like the CSS was missing. At the moment everything looks fine again.

Thanks for testing it and reporting what you find. I'll try to get this thread to one of the devs attention.

Should be fixed now. One file got missed from when da boss man migrated that server from Apache 2.2 to Apache 2.4.
