A new study could explain why "daddy" and "mommy" are often a baby's first words – the human brain may be hard-wired to recognize certain repetition patterns. Using the latest optical brain imaging techniques, University of British Columbia post-doctoral fellow Judit Gervain and a team of researchers from Italy and Chile documented brain activities of twenty-two newborns (two to three days old) when exposed to recordings of made-up words 
Animal Intelligence and the Evolution of the Human Mind

The human brain lacks conspicuous characteristics—such as relative or absolute size—that might account for humans’ superior intellect. This article in Scientific American is a smoothly written and interesting discussion of how scientists have found ways to measure intelligence in non-human species--especially primates--and of the speculation on the reasons behind human intelligence.

If you hide your real hand under a cloth and place a rubber or plastic hand where your real hand ought to be and then have someone touch both real and false hands in the same way, you will begin to feel as if the sensation is coming from the false hand. Scientists have used this technique for years to figure out how people perceive body boundaries.
The spooky part? The body temperature of the real hand will decrease. So will sensation.

There's no real difference between the scores of U.S. boys and girls on common math tests, according to a massive new study. Educators hope the finding will finally dispel lingering perceptions that girls don't measure up to boys when it comes to crunching numbers.
"This shows there's no issue of intellectual ability--and that's a message we still need to get out to some of our parents and teachers," says Henry "Hank" Kepner, president of the National Council of Teachers of Mathematics in Reston, Virginia.
It won't be a new message
Thanks for the future memories
sea-maid submitted, created time 2 months 2 weeks (www.sciencenews.org)
Scientists have found that the same machinery that we use to construct our memories of the past also helps us to imagine and envision the future.
Other studies show that total amnesiacs report a “blank” when asked about their personal futures. And severely depressed patients, who tend to think about both the past and future in a nonspecific manner, have difficulty visualizing positive future events.
This article also discusses different kinds of memories, how they're constructed, and how they might contribute to an individual's life and survival.
Happy thoughts may dampen cravings

Want to quit smoking? Next time the urge to light up strikes, think of snow-capped peaks instead of the fleeting pleasure of a white cigarette. That's the conclusion of a new brain study which shows that thinking happy thoughts could help dampen cravings.
Mauricio Delgado, a cognitive neuroscientist at Rutgers University in Newark, New Jersey, and his colleague Elizabeth Phelps of New York University measured the brain activity of 15 volunteers as they played a simple game.
The researchers told their subjects to associate blue cards with a real $4 payoff, and yellow cards with nothing

The main strength of the paper is that it shows how the two different "moral motivations" were isolated and details the investigation of how they are represented in the brain.
Location, location, location. Voting sites affect voting outcomes.

This study shows that people who vote in a certain type of building, such as a church or school, are more likely to vote for the canditate who is, say, better on education. I'm surprised that it took us this long to figure that out, but I have to say that I'm pleased. It means that at least a few American voters bothered to find out where their candidates stood on education.

Girls who eat more omega-3 fatty acids outsmart those who eat higher amounts of omega-6 fatty acids, according to new research. As a result of this and other studies, government dietary recommendations--especially those aimed at pregnant women--should emphasize fish over soy and corn oils, which are respectively high in these fatty acids.
Women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children

Emotion plays a critical role in many contemporary accounts of decision making, but exactly what underlies its influence and how this is mediated in the brain remain far from clear. Here, researchers review behavioral studies that suggest that Pavlovian processes can exert an important influence over choice and may account for many effects that have traditionally been attributed to emotion...

Monkeys show amazing learning curve with thought-controlled prosthetics
Darkfrog submitted, created time 4 months 1 week (www.nytimes.com)
Monkeys with small (as in a mm or so wide) grid implanted just beneath their skulls have shown themselves able to control a mechanical arm with their thoughts.
This is an NYT writeup of an article originally published in Nature. Scientists first taught the monkeys how to control a mechanical arm with a joystick, then implanted a small grid, only a mm or so wide, onto the motor centers of their brains. The monkeys' own arms were then gently restrained. The scientists used a computer to move the arm at first. The article uses the expression, "teaching with biofeedback
