New way to study uterine fluid in the lab could avoid invasive procedures during pregnancy

The quest to create safer, more successful pregnancies is one of the top goals of modern science. While pregnancy is better understood today than ever before, with improvements in technology helping to lower the risk of negative outcomes, there is much researchers still don't know about a vital part of the pregnancy process: uterine fluid.

Scientists identify the language the body uses to marshal responses to threats

UCLA life scientists have identified six "words" that specific immune cells use to call up immune defense genes -- an important step toward understanding the language the body uses to marshal responses to threats.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.
