Abstinence-only education does not lead to abstinent behavior, researchers find Posted: 29 Nov 2011 03:59 PM PST States that prescribe abstinence-only sex education programs in public schools have significantly higher teenage pregnancy and birth rates than states with more comprehensive sex education programs, researchers have determined.

3-D printer used to make bone-like material Posted: 29 Nov 2011 03:59 PM PST It looks like bone. It feels like bone. For the most part, it acts like bone. And it came off an inkjet printer. Researchers have used a 3-D printer to create a bone-like material that can be used in orthopedic procedures, dental work, and to deliver medicine for treating osteoporosis. Paired with actual bone, it acts as a scaffold for new bone to grow on and ultimately dissolves with no apparent ill effects.

High blood sugar levels in older women linked to colorectal cancer Posted: 29 Nov 2011 03:59 PM PST Elevated blood sugar levels are associated with an increased risk of colorectal cancer, according to a new study. The findings were observed in nearly 5,000 postmenopausal women.

Crash experts find car seats protect overweight kids, too Posted: 29 Nov 2011 01:29 PM PST Researchers have found no evidence of increased injury risk among crash-involved children across a broad weight range, when they were properly restrained in the correct child safety seat or booster seat for their height and weight.

Preclinical effectiveness of TB drug target validated Posted: 29 Nov 2011 12:15 PM PST Scientists evaluating new drug targets against tuberculosis recently validated the preclinical effectiveness of a target that could rapidly eliminate infections and potentially shorten treatment time. The new drug target is a protein called DNA gyrase B, found in bacteria that cause TB infections.

Gene acts as a brake on breast cancer progression Posted: 29 Nov 2011 11:20 AM PST New research provides compelling new evidence that a gene known as 14-3-3sigma plays a critical role in halting breast cancer initiation and progression.

Gray matter in brain's control center linked to ability to process reward; Structure-function impairments observed in people addicted to cocaine Posted: 29 Nov 2011 10:11 AM PST The more gray matter you have in the decision-making, thought-processing part of your brain, the better your ability to evaluate rewards and consequences. A new study is the first to show this link between structure and function in healthy people -- and the impairment of both in people addicted to cocaine.

Seeking to be the 'perfect parent' not always good for new moms and dads Posted: 29 Nov 2011 09:33 AM PST Parents of newborns show poorer adjustment to their new role if they believe society expects them to be "perfect" moms and dads, a new study shows. Moms showed less confidence in their parenting abilities and dads felt more stress when they were more worried about what other people thought about their parenting skills.

Medical marijuana laws reduce traffic deaths, preliminary research suggests Posted: 29 Nov 2011 09:32 AM PST A new study shows that laws legalizing medical marijuana lead to fewer traffic deaths and less consumption of alcohol.

Is there a central brain area for hearing melodies and speech cues? Still an open question Posted: 29 Nov 2011 08:23 AM PST Previous studies have suggested a particular hotspot in the brain might be responsible for perceiving pitch, but auditory neuroscientists are still debating whether this "pitch center" actually exists. A review article discusses a recent study claiming that this pitch center may not exist after all, or may not be located where previous research has suggested.

Environment and diet leave their prints on the heart Posted: 29 Nov 2011 06:24 AM PST A new study, which set out to investigate DNA methylation in the human heart and the "missing link" between our lifestyle and our health, has now mapped the link in detail across the entire human genome.

Frequent 'heading' in soccer can lead to brain injury and cognitive impairment Posted: 29 Nov 2011 06:24 AM PST Using advanced imaging techniques and cognitive tests, researchers have shown that repeatedly heading a soccer ball increases the risk for brain injury.

New findings about unwanted fungal growth on dry-cured meat products Posted: 29 Nov 2011 06:20 AM PST The growth of yeast and mold fungus often poses a threat to the quality of dry-cured meat and is a problem facing producers all over the world. Fungal growth can lead to bad quality products, increased production costs and health issues in consumers.
