Epigenetic factor likely plays a key role in fueling most common childhood cancer Posted: 10 Jun 2013 10:35 AM PDT Changes in an epigenetic mechanism that turns expression of genes on and off may be as important as genetic alterations in causing pediatric acute lymphoblastic leukemia, according to a new study.

Potential new target to thwart antibiotic resistance: Viruses in gut confer antibiotic resistance to bacteria Posted: 10 Jun 2013 10:35 AM PDT Bacteria in the gut that are under attack by antibiotics have allies no one had anticipated, scientists have found. Gut viruses that usually commandeer the bacteria, it turns out, enable them to survive the antibiotic onslaught, most likely by handing them genes that help them withstand the drug.

Early exposure to bisphenol A might damage the enamel of teeth Posted: 10 Jun 2013 10:32 AM PDT Are teeth the latest victims of bisphenol A? Yes, according to the conclusions of new work. Researchers have shown that the teeth of rats treated with low daily doses of BPA could be damaged by this.

A rather complex complex: Brain scans reveal internal conflict during Jung's word association test Posted: 10 Jun 2013 10:31 AM PDT Over 100 years ago psychologist Carl Gustav Jung penned his theory of 'complexes' where he explained how unconscious psychological issues can be triggered by people, events, or Jung believed, through word association tests.

Pendulum swings back on 350-year-old mathematical mystery Posted: 10 Jun 2013 10:31 AM PDT A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, researchers report.

The diabetes 'breathalyzer' Posted: 10 Jun 2013 10:31 AM PDT Chemists have demonstrated a sensor technology that could significantly simplify the diagnosis and monitoring of diabetes through breath analysis alone.

Master regulator in cancer metastasis discovered Posted: 10 Jun 2013 10:31 AM PDT In the process of metastasis, the movement of cancer cells to different parts of the body, a specific master regulator gene plays a central role: a transcription factor named Sox4 activates a sequence of genes and triggers the formidable process. Inhibition of Sox4 and subsequent processes may prevent metastasis in cancer patients.

The body electric: Researchers move closer to low-cost, implantable electronics, study suggests Posted: 10 Jun 2013 10:29 AM PDT New technology is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body. The first planned use of the technology is a sensor that will detect the very early stages of organ transplant rejection.

Cardiac MRI use reduces adverse events for patients with acute chest pain Posted: 10 Jun 2013 10:29 AM PDT Doctors have found that using stress cardiac magnetic resonance (CMR) imaging in an Emergency Department observation unit to care for patients with acute chest pain is a win-win – for the patient and the institution.

Transplant patient outcomes after trauma better than expected Posted: 10 Jun 2013 10:28 AM PDT In the largest study of its kind, researchers find that traumatic injury outcomes in patients with organ transplants are not worse than for non-transplanted patients, despite common presumptions among physicians. Additionally, transplanted organs are rarely injured in traumatic events.
