- Fixed versus growth intelligence mindsets: It’s all in your head, Dweck says
02-16-2007 · EurekAlert!
Stanford psychologist Carol Dweck says that people's self-theories about intelligence have a profound influence on their motivation to learn. People who have a "fixed" theory are mainly concerned with how smart they are -- they prefer tasks they can already do well and avoid ones on which they may make mistakes and not look smart. In contrast, people who believe in a "growth" theory of intelligence want to challenge themselves to increase their abilities, even if they fail at first.

- Do galaxies follow Darwinian evolution?
12-06-2006 · EurekAlert!
Using VIMOS on ESO's Very Large Telescope, a team of French and Italian astronomers have shown the strong influence the environment exerts on the way galaxies form and evolve. The scientists have for the first time charted remote parts of the Universe, showing that the distribution of galaxies has considerably evolved with time, depending on the galaxies' immediate surroundings. This surprising discovery poses new challenges for theories of the formation and evolution of galaxies.

- Tufts University biologists link Huntington's disease to health benefits in young
09-25-2007 · EurekAlert!
Hypothesis by Tufts University researchers explain prevalence of the disease by suggesting that people with Huntington's disease are healthier in childbearing years and have more children than general population. Huntington's strengthens the immune system during most fertile years allowing them to produce more offspring. Symptoms associated with Huntington's occur later in life, after peak reproductive age. The researchers' hypothesis challenges a long held belief that people with Huntington's had more children because of promiscuous behavior.
