Female choice key to evolutionary shift to modern family Posted: 30 May 2012 02:20 PM PDT How females chose their mates played a critical role in human evolution by leading to monogamous relationships, which laid the foundation for the institution of the modern family.

Marriage may make people happier Posted: 30 May 2012 12:23 PM PDT Married people may be happier in the long run than those who aren't married, according to new research.

Eat healthy -- your kids are watching Posted: 30 May 2012 12:23 PM PDT If lower-income mothers want kids with healthy diets, it's best to adopt healthy eating habits themselves and encourage their children to eat good foods rather than use force, rewards or punishments, says a new study.

Potential new HIV vaccine/therapy target Posted: 30 May 2012 12:22 PM PDT A new discovery may shed light on the mystery of why some people infected with HIV are better able to control the virus, live longer and have fewer associated health problems than others who have been infected as long. It also provides a potential new target for developing therapies or vaccines.

First epigenome in Europe completed Posted: 30 May 2012 10:37 AM PDT Scientists have now completed the first epigenome in Europe.

Despite less play, children's use of imagination increases over two decades Posted: 30 May 2012 10:37 AM PDT Children today may be busier than ever, but psychologists have found that their imagination hasn't suffered -- in fact, it appears to have increased.

Light-induced delivery of nitric oxide eradicates drug-resistant bacteria Posted: 30 May 2012 10:37 AM PDT Researchers have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. Medical researchers developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder.

A trained palate: Understanding complexities of taste, smell could lead to improved diet Posted: 30 May 2012 10:37 AM PDT Researchers have made some fundamental discoveries about how people taste, smell and detect flavor, and why they love some foods much more than others. The findings could lead to the Holy Grail of nutrition -- helping people learn to really like vegetables.

To spread, nervous system viruses sabotage cell, hijack transportation Posted: 30 May 2012 10:37 AM PDT Researchers have found that herpes and other viruses that attack the nervous system may thrive by disrupting cell function in order to hijack a neuron's internal transportation network and spread to other cells.

Genetic variant increases risk of heart rhythm dysfunction, sudden death Posted: 30 May 2012 10:37 AM PDT Cardiovascular researchers have identified a genetic variant in a cardiac protein that can be linked to heart rhythm dysfunction.

Genes predict if medication can help you quit smoking Posted: 30 May 2012 08:58 AM PDT A new study shows the same gene variations that make it difficult to stop smoking also increase the likelihood that heavy smokers will respond to nicotine-replacement therapy and drugs that thwart cravings. The finding suggests it may one day be possible to predict which patients are most likely to benefit from drug treatments for nicotine addiction.

BioChip may make diagnosis of leukemia and HIV faster, cheaper Posted: 30 May 2012 07:40 AM PDT Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers.

Speeding up drug discovery with rapid 3-D mapping of proteins Posted: 30 May 2012 07:07 AM PDT A new method for rapidly solving the three-dimensional structures of a special group of proteins, known as integral membrane proteins, may speed drug discovery by providing scientists with precise targets for new therapies.

Misuse of over-the-counter pain medication is potential health threat Posted: 30 May 2012 07:04 AM PDT A significant number of adults are at risk of unintentionally overdosing on over-the-counter (OTC) pain medication, according to a new study.

Ketamine improved bipolar depression within minutes, study suggests Posted: 30 May 2012 07:02 AM PDT Bipolar disorder is a serious and debilitating condition where individuals experience severe swings in mood between mania and depression. The episodes of low or elevated mood can last days or months, and the risk of suicide is high.

Hear to see: New method for the treatment of visual field defects Posted: 30 May 2012 07:02 AM PDT Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly. Neural pathways that simultaneously process information from different senses are responsible for this effect.

New findings on astronaut vision loss Posted: 30 May 2012 06:31 AM PDT Could vision changes experienced by astronauts be linked to a vitamin B-12 or folate deficiency? While investigating the vision changes recently identified in astronauts, nutritional assessment data showed similarities to symptoms that occur with vitamin deficiencies, according to a new study.

Less couch time equals fewer cookies Posted: 28 May 2012 02:56 PM PDT Simply changing one bad health habit has a domino effect on others, a new study reports. It's a two-for-one benefit because many behaviors are closely related, like noshing in front of the TV. The most effective way to rehab a delinquent lifestyle requires two key behavior changes: cutting time spent in front of a TV or computer screen and eating more fruits vegetables. The simplified strategy is less overwhelming for people and their doctors.
