Study links sleep to mood disturbance, poor quality of life in obese Posted: 04 Dec 2013 03:24 PM PST A new study shows that poor sleep quality is strongly associated with mood disturbance and lower quality of life among people with extreme obesity.

Social stigmas may contribute to African-American college students' hesitation to breast-feed Posted: 04 Dec 2013 03:24 PM PST A researcher has found that African-American college students are aware of the benefits of breast-feeding for infants, yet some still are hesitant about breast-feeding future children. Evidence revealed a lack of public acceptance toward breast-feeding may influence this hesitation.

IVF improving, but fertility treatments keep multiple births high Posted: 04 Dec 2013 03:18 PM PST More than one in three twin births and three of four births of triplets or more in the United States arise from fertility treatments, according to new estimates published. Although in-vitro fertilization (IVF) practices have improved to produce fewer triplets or higher-order births than at peak, multiples from non-IVF treatments continue unabated.

Data on people's self-reported 'experienced' well-being could help inform policies Posted: 04 Dec 2013 09:37 AM PST Gathering survey data on "experienced" well-being – the self-reported levels of contentment, joy, stress, frustration, and other feelings people experience throughout the day and while engaged in various activities -- would be valuable to inform policies, says a new report.

Working odd shifts can hurt parent-child relationships Posted: 04 Dec 2013 07:36 AM PST Research shows that working a job that doesn't keep 9 a.m. to 5 p.m. hours can hurt the relationships between parents and adolescents, increasing the likelihood that children will engage in delinquent behaviors. However, the researchers found that in some circumstances, an unconventional work schedule can be a benefit for children.

Dads: How important are they? New research highlights value of fathers in both neurobiology and behavior of offspring Posted: 04 Dec 2013 06:16 AM PST Even with today's technology, it still takes both a male and a female to make a baby. But is it important for both parents to raise that child? Many studies have outlined the value of a mother, but few have clearly defined the importance of a father, until now. New findings show that the absence of a father during critical growth periods, leads to impaired social and behavioral abilities in adults.

Mammography screening intervals may affect breast cancer prognosis Posted: 04 Dec 2013 06:14 AM PST In a study of screening mammography-detected breast cancers, patients who had more frequent screening mammography had a significantly lower rate of lymph node positivity -- or cancer cells in the lymph nodes -- as compared to women who went longer intervals between screening mammography exams.

Looks are all important for girls on tween TV Posted: 04 Dec 2013 06:11 AM PST Researchers believe that television programs for 8- to 12-year-olds may skew their concepts about gender roles. "Girls can participate in everything that boys can, but while doing so they should be attractive." This, according to American researchers, is one of the gender ideals conveyed by tween television programs to their young viewers.

Depression in pregnant mothers may alter the pattern of brain development in their babies Posted: 04 Dec 2013 06:09 AM PST Depression is a serious mental illness that has many negative consequences for sufferers. But depression among pregnant women may also have an impact on their developing babies. Children of depressed parents are at an increased risk of developing depression themselves, a combination of both genetic and environmental factors. These children also display alterations in the amygdala, a brain structure important for the regulation of emotion and stress.

Omega-3 dietary supplements pass blood-brain barrier Posted: 04 Dec 2013 06:09 AM PST New research shows that omega-3 fatty acids in dietary supplements can cross the blood brain barrier in people with Alzheimer's disease, affecting known markers for both the disease itself and inflammation. The findings strengthen the evidence that omega-3 may benefit certain forms of this seriously debilitating disease.

Corporate culture of respect prevents workplace sexual harassment Posted: 04 Dec 2013 06:09 AM PST Potentially harassing behavior is a daily occurrence in many places – and it's not always men who are the offenders and women the victims. There is no such thing as a typical offender or victim profile; much more important is the corporate culture, states a new Swiss study.

For top teacher pay, it's all about location, location, location Posted: 04 Dec 2013 06:08 AM PST Where you live has a strong bearing on what you're paid as a public-school teacher in the State of New York. Median salaries for teachers with Master's degrees and 10 years experience range from $45,882 in the Mohawk Valley to a high of $81,852 on Long Island, according to a recent study.

Exercise beneficial for dementia Posted: 03 Dec 2013 06:01 PM PST Exercise may benefit older people with dementia by improving their cognitive functioning and ability to carry out everyday activities, according to a new systematic review. However, the authors of the review did not see any clear effect of exercise on depression in older people with dementia and say that more evidence is needed to understand how exercise could reduce the burden on family caregivers and health systems.

Sounding tall: Listeners can distinguish the voices of tall versus short people Posted: 03 Dec 2013 01:15 PM PST Our voice can reveal a lot about us: our age, our gender, and now – it seems – our height as well. A new study found that listeners can accurately determine the relative heights of speakers just by listening to them talk. The key clue may be contained in a particular type of sound produced in the lower airways of the lungs, known as a subglottal resonance.

First real-time flu forecast successful Posted: 03 Dec 2013 08:22 AM PST Scientists were able to reliably predict the timing of the 2012-2013 influenza season up to nine weeks in advance of its peak. The first large-scale demonstration of the flu forecasting system by scientists was carried out in 108 cities across the United States.

Disability, distress in rheumatoid arthritis patients cut in half over last 20 years Posted: 03 Dec 2013 06:16 AM PST New research reveals that patients with rheumatoid arthritis today have an easier time with daily living than patients diagnosed two decades ago. According to results of the study, anxiety, depressed mood and physical disability have been cut in half over the last 20 years. Researchers believe a reduction in disease activity is partly responsible for this positive change.

3D mammography increases cancer detection, reduces call-back rates Posted: 03 Dec 2013 06:05 AM PST Compared to traditional mammography, 3D mammography found 22 percent more breast cancers and led to fewer call backs in a large screening study.

Aerobic fitness, hormones predict recognition memory in young adults Posted: 02 Dec 2013 01:22 PM PST Researchers have found further evidence that exercise may be beneficial for brain health and cognition. The findings suggest that certain hormones, which are increased during exercise, may help improve memory.
