Pregnancy, Stress And Schizophrenia
Risk only increased during early pregancy "Children born to women who suffer severe stress early in pregnancy are at increased risk of developing schizophrenia later in life," The Daily Telegraph reported.The newspaper said that a Danish study of 1.38million births from 1973 to 1995 found the risk of schizophrenia increased by 67 per cent among the offspring of women who experienced the death of a relative during early pregnancy.

Sex Differences In Memory: Women Better Than Men At Remembering Everyday Events
There are several human characteristics considered to be genetically predetermined and evolutionarily innate, such as immune system strength, physical adaptations and even sex differences. Psychologists determine significant sex differences in episodic memory, a type of long-term memory based on personal experiences, favoring women. Specific results indicated that women excelled in verbal episodic memory tasks, such as remembering words, objects, pictures or everyday events, and men outperformed women in remembering symbolic, non-linguistic information, known as visuospatial processing. For example, the results indicate a man would be more likely to remember his way out of the woods.

Unique Martian Formation Reveals Brief Bursts Of Water
Several formations on Mars indicate incidents of rapid release of water from the planet's interior. Mars has many basins that contain formations that look like fans. A few of these fans, only about 10, have steps down into the basin. Since scientists first reported this feature three years ago, there has been no clear consensus on how they formed.

First Direct Observation Of 3-D Molecule Folding In Real Time
All the crucial proteins in our bodies must fold into complex shapes to do their jobs. These snarled molecules grip other molecules to move them around, to speed up important chemical reactions or to grab onto our genes, turning them "on" and "off" to affect which proteins our cells make. Since the discovery of RNA clumps called "riboswitches," in 2002, scientists have been striving to understand how they work and how they form. Now, researchers are looking closer than ever at how the three-dimensional twists and turns in a riboswitch come together by grabbing it and tugging it straight. By physically pulling on this loopy RNA, they have determined for the first time how a three-dimensional molecular structure folds, step by step.
