Lung cancer drug could aid plight of ectopic pregnancy patients Posted: 09 Sep 2013 05:13 PM PDT Women with ectopic pregnancies could be spared surgery if they are treated with a lung cancer drug, a study suggests. Researchers treated ectopic pregnancies -- where an embryo implants inside the Fallopian tube -- by combining an existing treatment with a lung cancer therapy.

Copper destroys highly infectious norovirus Posted: 09 Sep 2013 05:12 PM PDT Scientists have discovered that copper and copper alloys rapidly destroy norovirus – the highly-infectious sickness bug. Worldwide, norovirus is responsible for more than 267 million cases of acute gastroenteritis every year.

Turning to parasites as potential disease fighters Posted: 09 Sep 2013 05:12 PM PDT Researchers have described exciting progress in harnessing the human immune system's reaction to the presence of parasitic worms, as a way to lessen susceptibility to type 1 diabetes and other autoimmune and inflammatory diseases, as well as for use in promoting wound healing.

Testes size correlates with men's involvement in toddler care Posted: 09 Sep 2013 02:20 PM PDT Men with smaller testes are more likely to be involved in hands-on care of their toddlers, a new study by anthropologists finds. Smaller testicular volumes also correlate with more nurturing-related brain activity in fathers. The data suggest that the biology of human males reflects a trade-off between investments in mating versus parenting effort.

Toward treating disease the way artificial limbs replace the function of lost arms and legs Posted: 09 Sep 2013 01:20 PM PDT The vision for a new branch of medicine, inspired by the ancient field that began with peg legs and hand hooks has been named "molecular prosthetics." Scientists have described advances toward making molecular prosthetics a reality, including progress in developing a platform that would revolutionize the now-tedious processes of making or synthesizing the ingredients for those drugs.

Translating nature's library yields drug leads for aids, cancer, Alzheimer's disease Posted: 09 Sep 2013 01:20 PM PDT An ingredient in a medicinal tea brewed from tree bark by tribal healers on the South Pacific island of Samoa — studied by scientists over the last 25 years — is showing significant promise as a drug lead in the long-sought goal of eliminating the AIDS virus from its sanctuaries in the body and thus eradicating the disease, a scientist said.

Toward making people invisible to mosquitoes Posted: 09 Sep 2013 12:28 PM PDT In an advance toward providing mosquito-plagued people, pets and livestock with an invisibility cloak against these blood-sucking insects, scientists today described discovery of substances that block mosquitoes' ability to smell and target their victims.

eButton health monitor gets a facelift Posted: 09 Sep 2013 10:12 AM PDT A wearable, picture-taking health monitor has received a recent facelift. Now, in addition to documenting what a person eats, the eButton prototype can accurately match those images against a geometric-shape library, providing a much easier method for counting calories.

Positive interactions vital to pre-K learning Posted: 09 Sep 2013 10:09 AM PDT A new study shows young children improve self-regulation skills in classrooms where teachers exhibit approving behavior with a positive emotional tone.

Vehicle/motorcycle accident regularity possibly linked to brain miscalculating time of impact of smaller objects Posted: 09 Sep 2013 10:09 AM PDT Results show that small, near objects can appear farther away than larger, farther objects.

Programmable glue made of DNA directs tiny gel bricks to self-assemble Posted: 09 Sep 2013 09:19 AM PDT A team of researchers has found a way to self-assemble complex structures out of bricks smaller than a grain of salt. The new method could help solve one of the major challenges in tissue engineering: Creating injectable components that self-assemble into intricately structured, biocompatible scaffolds at an injury site to help regrow human tissues.

Parents' genes may influence children's back to school fears Posted: 09 Sep 2013 09:19 AM PDT Many parents may have noticed their children seemed on edge during their first week of school. They may have been agitated, withdrawn or more focused on themselves, rather than what was going on around them. Such behaviors are classic symptoms of high anxiety.

How bedbugs shrug off pesticides and simple measures to deal with it Posted: 09 Sep 2013 09:18 AM PDT The bedbug's most closely guarded secrets — stashed away in protective armor that enables these blood-sucking little nasties to shrug off insecticides and thrive in homes and hotels. The talk includes implications for millions of people trying to cope with bed bug infestations that have been resurging for more than a decade.

Early detection of Parkinson’s disease through handwriting Posted: 09 Sep 2013 07:50 AM PDT The primary tool for diagnosing Parkinson's is the diagnostic ability of the physician. A new study compares the writing process of 40 sick and healthy subjects and suggests an innovative and noninvasive method of diagnosing Parkinson's at a fairly early stage.

Recycled sewage water is safe for crop irrigation, study suggests Posted: 09 Sep 2013 07:47 AM PDT The first study under realistic field conditions has found reassuringly low levels of chemicals from pharmaceuticals and personal care products in crops irrigated with recycled sewage water, scientists have reported.

First animal model of adult-onset SMA sheds light on disease progression & treatment Posted: 09 Sep 2013 06:31 AM PDT A research team has used a recently developed technology they call TSUNAMI to create the first animal model of the adult-onset version of spinal muscular atrophy, a devastating motor-neuron illness.

More breast cancer screening needed in younger women Posted: 09 Sep 2013 06:31 AM PDT A new analysis confirms the need for greater use of annual mammography in women ages 40-49. It also confirms that, even with new therapeutics and protocols for treating breast cancer, regular mammography screening is still the best way to significantly reduce breast cancer deaths.

Children referred for chest pain rarely have cardiac disease Posted: 09 Sep 2013 06:31 AM PDT Employing a unique quality improvement methodology, physicians have demonstrated that chest pain in children, rarely caused by heart disease, can be effectively evaluated in the ambulatory setting using minimal resources, even across a diverse patient population.

Capturing brain activity with sculpted light Posted: 09 Sep 2013 06:25 AM PDT A major aim of today's neuroscience is to understand how an organism's nervous system processes sensory input and generates behavior. To achieve this goal, scientists must obtain detailed maps of how the nerve cells are wired up in the brain, as well as information on how these networks interact in real time.

Is bigger really better when it comes to size of labor wards? Posted: 09 Sep 2013 06:25 AM PDT New research reveals that large labor wards — those handling 3,000 to 3,999 deliveries annually — have better overall approval rates compared to small, intermediate or very large obstetric units. The study suggests that greater access to in-house obstetricians and auxiliary specialists contributes to the lower obstetric injury claims from patients at large labor wards in Denmark

Severity of sleep apnoea predicts aggressiveness of melanoma Posted: 09 Sep 2013 06:24 AM PDT The severity of sleep apnoea can independently predict the aggressiveness of malignant skin melanoma, according to a new study.

Severe asthma patients less responsive to treatment Posted: 09 Sep 2013 06:24 AM PDT People with severe asthma, who are often described as 'steroid-dependent', are actually less likely to respond to the treatment they depend on, when compared to people with mild asthma.

Breath tests could be used to diagnose lung cancer Posted: 09 Sep 2013 06:24 AM PDT Collecting samples of exhaled breath from people at a high risk of lung cancer could be a cheap and non-invasive method of diagnosing the disease, according to new research.

New 'artificial nose' device can speed diagnosis of sepsis Posted: 09 Sep 2013 06:23 AM PDT Disease-causing bacteria stink — literally — and the odor released by some of the nastiest microbes has become the basis for a faster and simpler new way to diagnose serious blood infections and finger the specific microbe, scientists have reported.
