New marker, new target in Ewing's sarcoma Posted: 29 Jun 2012 06:19 PM PDT A new study implicates the protein EYA3 in Ewing's sarcoma chemoresistance. Checking level could help offer accurate prognosis and aid in treatment decisions, and could eventually provide a therapeutic target.

Skin contact breast tumor detection Posted: 29 Jun 2012 06:18 PM PDT A simple and cost effective imaging device for breast tumor detection based on a flexible and wearable antenna system has been developed. Researchers point out that their system holds the promise of much earlier detection than mammography.

Accelerated radiation effective for noninvasive breast cancer: Cut treatment time in half, study suggests Posted: 29 Jun 2012 06:15 PM PDT Accelerated whole breast irradiation after lumpectomy is an effective treatment for ductal carcinoma in situ (DCIS), a very common early stage and noninvasive form of breast cancer, meaning many more breast cancer patients could see their treatment times reduced by half, according to a new study.

FOXO1 gene may play important role in Parkinson's disease Posted: 29 Jun 2012 11:26 AM PDT A recent study revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

Help for cardiac arrest patients -- fast and without electricity Posted: 29 Jun 2012 09:03 AM PDT Textile cooling pads are to be used in future to prevent neurological damage after successful resuscitation. The system requires no electric power, making it ideal especially for first aid in case of cardiac arrest.

Meat-like vegetarian fare: Replicating the nutrition, texture and taste of meat and eggs Posted: 28 Jun 2012 09:53 PM PDT Food scientists are working to replicate the nutrition, as well as the texture, taste and functionalities of meat and eggs, by utilizing plant-based products and in-vitro technologies, according to new research.

TB treatment paradox: Mouse studies show body's own response helps TB bacteria survive Posted: 28 Jun 2012 11:57 AM PDT Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could -- paradoxically -- shorten treatment time for the highly contagious lung infection according to new research.

Giant raft of data to help us understand disease Posted: 28 Jun 2012 11:56 AM PDT Scientists have used a new method to assemble a massive catalog of data on proteins. This gives them unprecedented insight into a process called protein phosphorylation.

Taking the fate of stem cells in hand: Immature nerve cells generated Posted: 28 Jun 2012 11:56 AM PDT Biologists have deliberately transformed stem cells from the spinal cord of mice into immature nerve cells. This was achieved by changing the cellular environment, known as the extracellular matrix, using the substance sodium chlorate. Via sugar side chains, the extracellular matrix determines which cell type a stem cell can generate.

Sensitive test helps improve vaccine safety Posted: 28 Jun 2012 10:14 AM PDT Salmonella Typhi (S. Typhi) is the causative agent of typhoid fever, a serious health threat resulting in some 22 million new cases yearly and approximately 217,000 fatalities. Researchers have been examining ways to detect the presence of S. Typhi in stool following inoculation with various vaccine strains.

Probing the roots of depression by tracking serotonin regulation at a new level Posted: 28 Jun 2012 10:14 AM PDT An interdisciplinary team of scientists have successfully tagged a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of individual molecules for the first time. This capability makes it possible to study the manner in which serotonin regulates mood, appetite and sleep at a new level of detail.

Building a better Rift Valley fever vaccine Posted: 28 Jun 2012 10:13 AM PDT Researchers have significantly improved an existing experimental vaccine for Rift Valley fever virus, making possible the development of a more effective defense against the dangerous mosquito-borne pathogen.

New cancer stem cell mechanism identified Posted: 28 Jun 2012 10:12 AM PDT A link between two genes which shows how stem cells could develop into cancer has been uncovered.
