New technology reduces, controls CT radiation exposure in children: CT scan radiation reduced by 37 percent Posted: 19 Jun 2013 01:47 PM PDT Patients at certain hospitals are being exposed to significantly less radiation during CT scans because of new technology that allows doctors to more tightly control radiation doses. The first-of-its-kind imaging software reduced overall radiation exposure from CT scans by 37 percent.

How neural stem cells create new and varied neurons Posted: 19 Jun 2013 01:47 PM PDT A new study examining the brains of fruit flies reveals a novel stem cell mechanism that may help explain how neurons form in humans.

Brain can plan actions toward things the eye doesn't see Posted: 19 Jun 2013 01:47 PM PDT People can plan strategic movements to several different targets at the same time, even when they see far fewer targets than are actually present, according to a new study.

A new model -- and possible treatment -- for staph bone infections Posted: 19 Jun 2013 01:47 PM PDT Osteomyelitis -- a debilitating bone infection most frequently caused by Staphylococcus aureus ("staph") bacteria – is particularly challenging to treat. Now, investigators have identified a staph-killing compound that may be an effective treatment for osteomyelitis, and they have developed a new mouse model that will be useful for testing this compound and for generating additional therapeutic strategies.

Estrogen is a new weapon against urinary tract infection in postmenopausal women Posted: 19 Jun 2013 01:46 PM PDT Estrogen stimulates the production of the body's own antibiotic and strengthens the cells in the urinary tract, according to a new study. The results show that estrogen supplements may help menopausal women to ward off recurrent urinary tract infections.

Fate of the heart: Researchers track cellular events leading to cardiac regeneration Posted: 19 Jun 2013 01:44 PM PDT Scientists have visually monitored the dynamic cellular events that take place when cardiac regeneration occurs in zebrafish after cardiac ventricular injury. Their findings provide evidence that various cell lines in the heart are more plastic, or capable of transformation into new cell types, than previously thought.

Dietary fructose causes liver damage in animal model Posted: 19 Jun 2013 01:44 PM PDT The role of dietary fructose in the development of obesity and fatty liver diseases remains controversial, with previous studies indicating that the problems resulted from fructose and a diet too high in calories. However, a new study conducted in an animal model showed that fructose rapidly caused liver damage even without weight gain. The researchers found that over the six-week study period liver damage more than doubled in the animals fed a high-fructose diet as compared to those in the control group.

Stroke symptoms associated with developing memory and thinking problems, even without stroke Posted: 19 Jun 2013 01:43 PM PDT People who experience any stroke symptoms —- but do not have a stroke —- may also be more likely to develop problems with memory and thinking, according to new research.

HIV-derived antibacterial shows promise against drug-resistant bacteria Posted: 19 Jun 2013 10:25 AM PDT Scientists have developed antibacterial compounds, derived from the outer coating of HIV, that could be potential treatments for drug-resistant bacterial infections and appear to avoid generating resistance.

Chemical that makes naked mole rats cancer-proof discovered Posted: 19 Jun 2013 10:24 AM PDT Scientists have discovered the chemical that makes naked mole rats cancer-proof. Naked mole rats are small, hairless, subterranean rodents that have never been known to get cancer, despite having a 30-year lifespan. Scientists discovered that these rodents are protected from cancer because their tissues are very rich with high molecular weight hyaluronan (HMW-HA).

Structure from disorder: Scientists find new source of versatility so 'floppy' proteins can get things done Posted: 19 Jun 2013 10:24 AM PDT Many proteins work like Swiss Army knives, fitting multiple functions into their elaborately folded structures. A bit mysteriously, some proteins manage to multitask even with structures that are unfolded and floppy -- "intrinsically disordered." Scientists have now discovered an important trick that a well-known intrinsically disordered protein uses to expand and control its functionality.

Nearly 7 in 10 Americans are on prescription drugs Posted: 19 Jun 2013 10:23 AM PDT Nearly 70 percent of Americans are on at least one prescription drug, and more than half take two, researchers say.

No danger of cancer through gene therapy virus, study suggests Posted: 19 Jun 2013 09:22 AM PDT The first modified adeno-associated virus was recently approved for clinical gene therapy in the Western world. Scientists say it appears that no cancer risk emanates from the virus used for gene delivery.

Antioxidant shows promise in Parkinson's disease Posted: 19 Jun 2013 09:21 AM PDT Diapocynin, a synthetic molecule derived from a naturally occurring compound (apocynin), has been found to protect neurobehavioral function in mice with Parkinson's Disease symptoms by preventing deficits in motor coordination.

What do memories look like? Posted: 19 Jun 2013 09:21 AM PDT Scientists develop a way to see the structures that store memories in a living brain.

Validating Maps of the Brain's Resting State Posted: 19 Jun 2013 09:19 AM PDT Researchers have provided important validation of maps of the brain at rest that may offer insights into changes in the brain that occur in neurological and psychiatric disorders.

New Alzheimer's research suggests possible cause: Interaction of proteins in brain Posted: 19 Jun 2013 07:28 AM PDT For years, Alzheimer's researchers have focused on two proteins that accumulate in the brains of people with Alzheimer's and may contribute to the disease: Plaques made up of the protein amyloid-beta, and tangles of another protein, called tau.

Stress hormone could trigger mechanism for the onset of Alzheimer's Posted: 19 Jun 2013 07:26 AM PDT A chemical hormone released in the body as a reaction to stress could be a key trigger of the mechanism for the late onset of Alzheimer's disease.

Researchers discover immunity mechanism: Platelets patrolling the bloodstream Posted: 19 Jun 2013 07:16 AM PDT Scientists have discovered a mechanism that is used to protect the body from harmful bacteria. Platelets, a component of blood typically associated with clotting, were discovered to actively search for specific bacteria, and upon detection, seal it off from the rest of the body. The findings provide the science community with a greater understanding of immunity.

Altered brain structure in pathological narcissism Posted: 19 Jun 2013 07:14 AM PDT A far-reaching disorder of the self-esteem is denoted as a narcissistic personality disorder. Persons with pathological narcissism on the one hand suffer from feelings of inferiority, while on the other hand projecting themselves to the world as arrogant, disparaging and self-absorbed. One of the key features of a narcissistic personality disorder is the lack of empathy. Although patients suffering from such a disorder are well able to recognize what other persons feel, think and intent, they display little compassion.

Distracted walking: Injuries soar for pedestrians on phones Posted: 19 Jun 2013 07:10 AM PDT More than 1,500 pedestrians were estimated to be treated in emergency rooms in 2010 for injuries related to using a cell phone while walking, according to a new nationwide study.

Research of essential molecule reveals important targets in diabetes and obesity Posted: 19 Jun 2013 07:10 AM PDT Medical researchers have made breakthrough advancements on a molecule that may provide more answers in understanding the precise molecular mechanisms by which insulin regulates glucose uptake in fat and muscle cells.

Moderate drinking during pregnancy does not seem to harm baby's neurodevelopment, study suggests Posted: 17 Jun 2013 05:27 PM PDT Moderate drinking during pregnancy -- 3 to 7 glasses of alcohol a week -- does not seem to harm fetal neurodevelopment, as indicated by the child's ability to balance, suggests a large study. In the study, moderate alcohol intake was a marker for social advantage, which may itself be the key factor in better balance, possibly overriding subtle harmful effects of moderate alcohol use, say the authors.
