...fascinating study published in the current issue of Science helps fill in a bit of the picture, drawing evidence from that research-friendly fellow mammal, the mouse. The authors, a team from State University of New York Downstate Medical Center, wanted to look at whether the ability to learn is affected by changes in brain chemistry that occur at puberty. They devised a task that was relatively complex (at least for a mouse) and required learning how to avoid a moving platform that delivered a very mild shock. (See the top 10 animal stories...
Smith and company found that having this abundance of receptors, which recede later in adolescence, interferes with learning. And just as fascinating, a dose of THP reverses the learning deficit. "We are suggesting that mild stress is advantageous to learning in adolescence," she says. (Smith's current study involved only female mice; she plans to look next at males and females to see if there are gender differences on the learning task...
...current wave of migration from the global South into the industrialized states is due to the failure of the IMF and the G-8's policies. The current global trading system is under exclusive control of the rich states, which doubtlessly want to keep it that way. Without the prospect of escaping poverty in their home countries any time soon, more and more people will decide to migrate north. The solution to the problem is not more rigid border policing, but a change of policy in the U.S. and Europe toward an equal global trading system that benefits all instead...
Merkel is indeed in the stronger position. The FDP won a record 14.6% of the vote in last September's election, but it was never going to join up with the left-of-center Social Democratic party. That means there is no real alternative to the current coalition. But Merkel's lack of authority remains worrying. "Angela Merkel's strategy is to calm things down - her coping style is emotional and palliative," says Thomas Kliche, a political psychologist at the University of Hamburg. The problem is, "stagnation doesn't overcome crisis...
...Pelosi agreed to an amendment authored by Stupak that barred any federal funds from subsidizing abortion on the health care exchange that is expected to be set up in 2014 to provide insurance to upwards of 31 million uninsured Americans. Prochoice groups were outraged, accusing Stupak of moving beyond current law, and the amendment was stripped out in the Senate and replaced with softer language that Stupak and his group felt did not go far enough. Sunday's last-minute Executive Order, expected to be signed by President Obama immediately following passage of the bill, was the compromise that allowed...
