Blood Test Identifies Heart-transplant Rejection Earlier than Biopsy Can

June 19, 2014 9:56 am | News | Comments

Stanford University researchers have devised a noninvasive way to detect heart-transplant rejection weeks or months earlier than previously possible. The test, which relies on the detection of increasing amounts of the donor’s DNA in the blood of the recipient, does not require the removal of any heart tissue.

Breathalyzer Test May Detect Deadliest Cancer

June 18, 2014 4:54 pm | News | Comments

Lung cancer causes more deaths in the U.S. than the next three most common cancers combined. The reason for the striking mortality rate is simple: poor detection. Lung cancer attacks without leaving any fingerprints, quietly afflicting its victims and metastasizing uncontrollably—to the point of no return. Now a new device may turn the tide by both accurately detecting lung cancer and identifying its stage of progression. 

Prostate Cancer Biomarkers Found in Seminal Fluid

June 6, 2014 12:35 pm | News | Comments

Improved diagnosis and management of one of the most common cancers in men- prostate cancer- could result from research, which has discovered that seminal fluid (semen) contains biomarkers for the disease.

May 30, 2014 12:13 pm | News | Comments

A sensor which can be used to screen for diabetes in resource-poor settings has been developed by researchers and tested in diabetic patients, and will soon be field tested in sub-Saharan Africa.               

Study Affirms Value of Epigenetic Test for Prostate Cancer Markers

May 29, 2014 2:11 pm | News | Comments

A multicenter team of researchers report that a commercial test designed to rule out the presence of genetic biomarkers of prostate cancer may be accurate enough to exclude the need for repeat prostate biopsies in many— if not most— men.    

New Venture Aims to Understand, Heal Disrupted Brain Circuitry

May 27, 2014 1:57 pm | Videos | Comments

Scientists and physicians at UC San Francisco are leading a $26 million, multi-institutional research program in which they will employ advanced technology to characterize human brain networks and better understand and treat a range of common, debilitating psychiatric disorders.

Cognitive Test Differentiates Between Alzheimer's, Normal Aging

May 21, 2014 12:31 pm | News | Comments

Researchers have developed a new cognitive test that can better determine whether memory impairments are due to very mild Alzheimer’s disease or the normal aging process.                       

Implanted Transistors Wrap Around Tissues

May 13, 2014 2:16 pm | Videos | Comments

Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels. These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and stimulate the body for treatments.
