UW center receives $16 million to work on first implantable device to reanimate paralyzed limbs
The University of Washington-led Center for Sensorimotor Neural Engineering has received a $16 million NSF grant to develop the first implantable device to reanimate paralyzed limbs and restore motor function in stroke or spinal cord injury patients.

Early-life exercise alters gut microbes, promotes healthy brain and metabolism
The human gut harbors a teeming menagerie of over 100 trillion microorganisms, and researchers at the University of Colorado Boulder have discovered that exercising early in life can alter that microbial community for the better, promoting healthier brain and metabolic activity over the course of a lifetime.

St. Jude researchers develop powerful interactive tool to mine data from cancer genome
St. Jude Children's Research Hospital has developed a web-based application to advance pediatric cancer research, collaboration and clinical care through enhanced exploration of the pediatric cancer genome

Technology aids kidney transplant patients
Mobile technology helps kidney transplant patients adhere to a rigorous schedule of medications and monitor their own blood pressure.

New breast cancer drug may be effective against other types of cancer
Palbociclib, a new oral drug whose efficacy in combating breast cancer has been demonstrated alone and in combination with endocrine therapy, also has potential to combat other types of cancer, according to a literature review and additional original research conducted by experts at the Abramson Cancer Center in the University of Pennsylvania published this month in JAMA Oncology.

A clue to generate electric current without energy consumption at room temperature
Researchers in Japan and China identified the requirements for the development of new types of extremely low power consumption electric devices by studying thin films made of Cr-doped (Sb, Bi)2Te3.

Study ties insurgency phase of Iraq War to higher PTSD rates
Guerilla tactics such as suicide attacks and roadside bombs may trigger more post-traumatic stress than conventional warfare, suggests a Veterans Affairs study of 738 Iraq veterans.

Geomorphic impact of the flooding caused by Tropical Storm Lee in September 2011
In their article for Geosphere, R. Craig Kochel and colleagues discuss the geomorphic impact of the flooding caused from Tropical Storm Lee in September 2011 on several large watersheds of the Susquehanna River in the Appalachian Plateau region of north-central Pennsylvania.

Thermal microscopy of single cells
Researchers in France working wondered whether it might be possible to tap into active thermography camera technology -- behind night-vision equipment and the thermal imaging of buildings -- to create a sort of thermal microscope to produce heat maps of single cells to help them understand the thermal behavior of the cells or go a step even further by detecting diseased conditions at the sub-cell scale.

Increased long-term death risk for adolescents hospitalized for adversity-related injury
Adolescents discharged from hospitals in England after an admission for violent, drug- or alcohol-related, or self-inflicted injuries have increased risks of subsequent death and emergency re-admission up to a decade later, according to a study published this week in PLOS Medicine.

NTU Singapore unveiled two social and telepresence robots today. One is Nadine, a friendly human-like robot who will greet you back and shake your hand.

Expanded regimens associated with improved treatment response in MDR-TB
Treating multidrug-resistant tuberculosis (MDR TB) with regimens that include a greater number of drugs may improve outcomes, and baseline drug susceptibility testing (DST) could identify drugs with the greatest likelihood of success, according to a paper published this week in PLOS Medicine.

Nearly one in four publicly sponsored cancer clinical trials fail to enroll enough participants to draw valid conclusions about treatments or techniques.

Improving accuracy in genomic mapping with time-series data
Researchers at the University of Minnesota and BioNano Genomics have improved a nanochannel-based form of mapping by using dynamic time-series data to measure the probability distribution, or how much genetic material separates two labels, based on whether the strands are stretched or compressed.

PRO as a sustainable energy production system is crippled by biofouling
According to the new study published in the journal Environmental Science & Technology, researchers at the Zuckerberg Institute and Yale University found that, 'power generation by PRO produces little and next to nothing due to biofouling caused by bacteria that clog the membrane structure and the feed channel.' Prior to this study, researchers from Yale reported that this technology is thermodynamically challenging and is hardly viable.
