...banks in the Treasury's Troubled Asset Relief Program issued or renewed $127 billion in business loans in November, roughly the same as five months ago. And bank lending, now at $6.7 trillion, is at the same level it was at the end of 2007, when the economy was still expanding. That would be a problem if we had serious inflation. When asset prices rise and loan values don't, that can signal economic stagnation. But at a time when many asset prices are falling, it makes sense that loan volumes would be falling as well. After all, the collateral...
...memories form, for example. But, says the study's lead author, Ian Maze, a doctoral student at Mount Sinai School of Medicine, "when you give an animal a single dose of cocaine, you start to have genes aberrantly turn on and off in a strange pattern that we are still trying to figure...
Increases in the number of these spines can reflect learning. But in the case of addiction, that may involve learning to connect a place or a person with the desire for more drugs. Maze showed that even after a week of abstinence, mice given a new dose of cocaine still had elevated levels of gene activation in the nucleus accumbens, meaning G9a levels were still low. It is not known how long these changes can last. Maze also showed that when he intervened and raised G9a levels, the mice were less attracted to cocaine...
...better understanding of the G9a pathways could lead to the development of safer, more specific drugs. And studying the genes that control G9a itself could also help screen people at risk for cocaine addiction: those with naturally lower levels of the protein would be the ones to watch. Still, there's a lot to be learned even from further mouse studies - particularly if the work involves younger mice, unlike the adults used in Maze's research.

...website is not for everyone, of course. For those whose problem is so serious that quitting entirely is the only safe route, more intensive treatment - often maintained indefinitely - may be needed. Still, for people on the borderline who don't want to find themselves in that danger zone in a few years, a little Web-based self-awareness may make a very big difference...
