Whew, I feel pretty good about my large hippocampus now. Wait. I don’t know how big my hippocampus is. I wonder if there’s a spammer with a product that might help enlarge that… hmm…

Having a large hippocampus – a part of the brain involved with memory – seems to provide protection against the symptoms of dementia, a study suggests.
A US team compared the brains of 35 people who had Alzheimer’s “plaques”, some of whom died with sharp minds and others who showed no dementia symptoms

I’m going to assume hundreds of studies saying “vitamins good” out-weigh this one that says they kill, but it will be interesting to see if this develops into anything else

Glad they’ve landed safely. There are some interesting stats on Peggy Whitson in a sidebar (she’s been up for 192 days).

A Russian Soyuz spacecraft has returned to Earth, but came down more than 400km (250 miles) away from its planned touchdown point, say Russian officials.
The crew are safe, but were subjected to severe G-forces during re-entry, said a spokesman for mission control.

Hormone’s driving the market? does this mean sex really does sell? Are the markets driven by machismo?

A Cambridge University team found testosterone levels were directly linked to the profit they made.
The Proceedings of the National Academy of Sciences study also found levels of the stress hormone cortisol could affect the risks they took.
A psychologist who works with investment bankers said it may help explain seemingly irrational behaviour.
