Women spend longer in labor now than 50 years ago Posted: 30 Mar 2012 01:48 PM PDT Women take longer to give birth today than did women 50 years ago, according to an analysis of nearly 140,000 deliveries. The researchers could not identify all of the factors that accounted for the increase, but concluded that the change is likely due to changes in delivery room practice.

Tales from the crypt lead researchers to cancer discovery Posted: 30 Mar 2012 09:32 AM PDT Tales from the crypt are supposed to be scary, but new research shows that crypts can be places of renewal too:  Intestinal crypts, that is. Intestinal crypts are small areas of the intestine where new cells are formed to continuously renew the digestive tract.  By focusing on one protein expressed in our intestines called Lrig1, the researchers have identified a special population of intestinal stem cells that respond to damage and help to prevent cancer.

Preschoolers tend to have negative perceptions of overweight children Posted: 30 Mar 2012 09:30 AM PDT A Canadian study has found that some preschoolers may perceive overweight children to be not as "nice".

Glycemic index foods at breakfast can control blood sugar throughout the day Posted: 30 Mar 2012 08:02 AM PDT Eating foods at breakfast that have a low glycemic index may help prevent a spike in blood sugar throughout the morning and after the next meal of the day, researchers say.

Menopause clinicians support new advice on steroid use Posted: 30 Mar 2012 05:17 AM PDT Glucocorticoids - a type of steroid hormone - are widely used in a number of medical disorders. Worldwide, it is estimated that almost 5% of postmenopausal women take glucocorticoids. As well as having specific benefits, Glucocorticoids have side effects. One of the potentially most important is that glucocorticoid use is associated with bone loss, which is most rapid in the first 3-6 months of treatment, potentially leading to serious complications and osteoporosis in many postmenopausal women.

Maintaining restraint in the face of danger Posted: 30 Mar 2012 05:12 AM PDT A central regulator of the inflammatory response shows signs as an appealing target for therapies against autoimmune disease.

Treating cancer as a chronic disease? Posted: 29 Mar 2012 02:02 PM PDT New research could someday lead to treatments that transform cancer from a lethal disease to a chronic, manageable one, similar to AIDS.

Intelligence is more accurate predictor of future career success than socioeconomic background, study suggests Posted: 29 Mar 2012 11:20 AM PDT When intelligence and socioeconomic background are pitted directly against one another, intelligence is a more accurate predictor of future career success, researchers have found.

Being bilingual wards off symptoms of dementia Posted: 29 Mar 2012 09:46 AM PDT New research explains how speaking more than one language may translate to better mental health. Scientists examine how being bilingual can offer protection from the symptoms of dementia, and also suggests that the increasing diversity in our world populations may have an unexpected positive impact on the resiliency of the adult brain.

Genome study confirms immune system link to disfiguring leg swelling Posted: 28 Mar 2012 02:22 PM PDT Genetic variants in a region of the genome linked to our immune response have been linked to increased risk of podoconiosis, a disfiguring and disabling leg swelling caused by an abnormal reaction to the minerals found in soil. An estimated four million people worldwide suffer from the condition.

In immersion foreign language learning, adults attain, retain native speaker brain pattern Posted: 28 Mar 2012 02:22 PM PDT In a series of studies, researchers demonstrate that the kind of exposure you have to a foreign language can determine whether you achieve native-language brain processing, and that learning under immersion conditions may be more effective in reaching this goal than typical classroom training. But they also show that the brain consolidates knowledge of the foreign language as time goes on.

More than half of all cancer is preventable, experts say Posted: 28 Mar 2012 12:44 PM PDT More than half of all cancer is preventable, and society has the knowledge to act on this information today, according to health researchers. Investigators now outline obstacles they say stand in the way of making a huge dent in the cancer burden in the United States and around the world.

HPV vaccination reduces the risk of infection even after a previous case of the disease, study suggests Posted: 28 Mar 2012 06:08 AM PDT The vaccination against human papillomavirus (HPV) reduces the risk of a renewed HPV-associated illness in patients who have already had diseases as a consequence of an HPV infection new research suggests. It had previously been the view that the HPV vaccination had a purely preventative effect and was also only effective in young women and men.

Afghans share unique genetic heritage, DNA analysis shows Posted: 27 Mar 2012 07:00 PM PDT A study by the Genographic Project has found that the majority of all known ethnic Afghans share a unique genetic heritage derived from a common ancestral population that most likely emerged during the Neolithic revolution and the formation of early farming communities. Through detailed DNA analysis of samples from 27 provinces, the Genographic team found the inter-Afghan genetic variability to be mostly attributed to the formation of the first civilizations in the region during the Bronze Age.
