A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development.

Claims that coastal tree barriers can halt the might of a tsunami are false and dangerous, according to a team of international marine scientists.

Facial expressions of emotion are hardwired into our genes, according to a study published today in the Journal of Personality and Social Psychology.

DARMSTADT, Germany — From the outside, there is nothing unusual about the stylish new gray and orange row houses in the Kranichstein District, with wreaths on the doors and Christmas lights twinkling through a freezing drizzle.

Researchers have found that pregnant women who are vitamin D deficient are also at an increased risk for delivering a baby by caesarean section as compared to pregnant women who are not vitamin D deficient. These findings currently appear on-line in the Journal of Clinical Endocrinology & Metabolism.

Participants in a study who slept on average an hour longer per night than other participants had an associated lower incidence of coronary artery calcification, which is thought to be a predictor of future heart disease.

A research team has discovered an unexpected mechanism governing alternative splicing, the process by which single genes produce different proteins in different situations.

Researchers have found that a molecule known to preserve memories – PKMzeta – specifically stores complex, high-quality memories that provide detailed information about an animal’s location, fears, and actions, but does not control the ability to process or express this information.

Researchers have discovered the atomic structure of a powerful “molecular motor” that packages DNA into the head segment of some viruses during their assembly, an essential step in their ability to multiply and infect new host organisms.

According to a new study, 52 percent of patients with REM sleep behavior disorder develop a neurodegenerative disease within 12 years after their initial diagnosis.
