What happens when we try to manipulate our voice to attract a mate? Her voice is hot, his is not Posted: 11 Apr 2014 12:33 PM PDT Trying to sound sexier? Sorry, guys, it seems you just don't have what it takes. New research suggests that men cannot intentionally make their voices sound more sexy or attractive, while women have little trouble. And true to the stereotype, women will lower their pitch and increase their hoarseness to dial up the allure.

Taking iron improves women's exercise performance, study shows Posted: 11 Apr 2014 06:23 AM PDT Women who take iron supplements experience a marked improvement in their exercise performance, a new study shows. Iron supplementation improved women's exercise performance, in terms of both the highest level they could achieve at 100% exertion (maximal capacity) and their exercise efficiency at a submaximal exertion. Women who were given iron were able to perform a given exercise using a lower heart rate and at a higher efficiency.

Young athletes from higher income families more likely to suffer serious overuse injuries Posted: 11 Apr 2014 06:13 AM PDT Young athletes from higher income families are more likely to specialize in one sport, and also more likely to suffer serious overuse injuries such as stress fractures, according to the first study of its kind. The rate of serious overuse injuries in athletes who come from families that can afford private insurance is 68 percent higher than the rate in lower-income athletes who are on public insurance (Medicaid), the study found.

'Body hack' app by math researchers shortcuts jet-lag recovery Posted: 10 Apr 2014 04:46 PM PDT A different kind of jet-lag mobile app released today by mathematicians reveals previously unknown shortcuts that can help travelers snap their internal clocks to new time zones as efficiently as possible.

Possible new target to attack flu virus identified Posted: 10 Apr 2014 12:36 PM PDT A protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms, researchers have found. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus. When an influenza virus infects a human cell, it uses some of the host's cellular machinery to make copies of itself, or replicate. In this study, the researchers discovered that a protein produced by human body cells, DDX21, blocks this replication process.

Single mothers don't delay marriage just to boost tax credit, study says Posted: 10 Apr 2014 12:35 PM PDT When the Earned Income Tax Credit was expanded in 1993 in the United States, supporters hoped it would reward poor parents for working while critics feared that it might discourage single mothers from marrying or incentivize women to have more children to boost their tax refund. A new collaborative study reveals the EITC has helped the working poor but hasn't affected personal choices.

Phone call from pharmacist can reduce some hospital admissions Posted: 09 Apr 2014 10:43 AM PDT Pharmacist-patient telephone consultations appear to reduce hospitalizations in patients who are least at risk, finds a new study. Providing medication management via phone calls from pharmacists to patients is one strategy being used to reduce medication errors, adverse reactions and drug interactions, all of which contribute to costly hospitalizations and harm to patients. The cost of medication-related illness and death in the United States was estimated to be more than $290 billion in 2009.

Glucosamine promotes longevity by mimicking low-carb diet, study finds Posted: 08 Apr 2014 09:21 AM PDT The widely used food supplement glucosamine promotes longevity in aging mice by approximately 10 percent due to improved glucose metabolism. Researchers find that the compound does so 'by mimicking a low-carb diet in elderly mice reflecting human retirees.' In addition, the results of the study seemed to give some indication of protection from diabetes, a life-threatening disease most prevalent amongst the elderly.

Kitchens are source of multi-drug resistant bacteria Posted: 08 Apr 2014 08:19 AM PDT After handling raw poultry, hands of food preparers and cutting boards remain a source of transmission for multi-drug resistant bacteria, such as E. coli that produce extended-spectrum beta-lactamases. "The spread of multi-drug resistant bacteria has been associated with the hospital setting, but these findings suggest that transmission of drug-resistant E. coli occurs both in the hospital and households," said the lead author of the study. "Our findings emphasize the importance of hand hygiene, not only after handling raw poultry, but also after contact with cutting boards used in poultry preparation."

Grandmas stay sharp when they care for grandkids once a week Posted: 08 Apr 2014 08:17 AM PDT Taking care of grandkids one day a week helps keep grandmothers mentally sharp, finds a study. That's good news for women after menopause, when women need to lower their risks of developing Alzheimer's disease and other cognitive disorders. On the other hand, taking care of grandchildren five days a week or more had some negative effects on tests of mental sharpness.

Higher blood pressure linked to lower tendency to worry Posted: 08 Apr 2014 08:14 AM PDT Blood pressure modulates a person's tendency to worry and can be associated with a "tranquilizing" effect when elevated. This is indicated in a new study that reflects how we can implicitly learn to increase our blood pressure as a way of alleviating tension and emotional unease. A new study points out that our predisposition to worry is linked with blood pressure and baroreceptor reflex sensitivity, fundamental in the stabilization of blood pressure and activated by receptors located in the aortic and carotid arteries.
