Scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn's largest moon, Titan. The recipe is used for lab experiments designed to simulate Titan's chemistry. With this approach, the team was able to classify a previously unidentified material discovered in the moon's smoggy haze.

Researchers have found that people with lower blood levels of vitamin D were twice as likely to die prematurely as people with higher blood levels of vitamin D. The finding was based on a systematic review of 32 previous studies that included analyses of vitamin D, blood levels and human mortality rates. The specific variant of vitamin D assessed was 25-hydroxyvitamin D, the primary form found in blood.

Geochemists have calculated a huge rise in atmospheric carbon dioxide was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangea. A new model explains some of the events in the 80 million years following the start of the Carboniferous period.

Researchers have experimentally demonstrated that interferometers, the most sensitive measuring instruments yet invented, can be improved using nonlinear physics. The result answers a fundamental question in quantum mechanics and could open the way to more sensitive detection of magnetic fields in delicate systems such as the human heart.

The Battle of Hastings is regularly fought all over again by enthusiastic re-enactors, before large crowds of spectators. The problem is that they are depositing material that could compromise the archaeology of the historic site. But now one of the world's leading battlefield archaeologists is developing a unique project designed to unearth whatever genuine material survives from 1066.

With just six months until its first trip to space, NASA's Orion spacecraft continues taking shape at the agency's Kennedy Space Center in Florida. Engineers began stacking the crew module on top of the completed service module Monday, the first step in moving the three primary Orion elements -crew module, service module and launch abort system -- into the correct configuration for launch.

This is the story of two perfectly harmless genes. By themselves, PAX3 and MAML3 don't cause any problems. However, when they combine during an abnormal but recurring chromosomal mismatch, they can be dangerous. The result is a chimera — a gene that is half of each — and that causes biphenotypic sinonasal sarcoma. The tumor usually begins in the nose and may infiltrate the rest of the face, requiring disfiguring surgery to save the individual.

New research on the Thwaits Glacier will help ice sheet modeling efforts needed to determine when the collapse of the glacier will begin in earnest and at what rate the sea level will increase as it proceeds.

A father's love contributes as much -- and sometimes more -- to a child's development as does a mother's love. That is one of many findings in a new large-scale analysis of research about the power of parental rejection and acceptance in shaping our personalities as children and into adulthood.
