VA Developing New Heat- Enhanced Pulse Ox Device

Probe improves accuracy in reading blood oxygen saturation levels in patients who are harder to read due to low core temperature. Pulse oximetry has gained widespread clinical acceptance as a standard patient vital sign measurement because it can give clinicians an early warning of low arterial blood oxygen saturation levels, or hypoxemia. Conventional pulse oximetry is subject to technological limitations that reduce its effectiveness and the quality of patient care. To mitigate the limitations of current technologies, the U.S. Department of Veterans Affairs (VA) has developed a novel device that provides reliable pulse oximetry measurements of oxygen saturation and heart rate in patients with low body temperature due to vasoconstriction and low blood perfusion.

Flexible Sensors Offer View into Epileptic Seizures

Brain activity can be monitored and sampled using minimal amount of wires and electrodes and improving implantable devices. Tapping into the human brain to understand its functions in daily life — as well as its malfunctions in illness — has long been a challenge for researchers. Mapping brain activity requires unwieldy, invasive arrays of electrodes and sensors that can damage tissue while only reading activity in a limited area. A team of researchers at the Polytechnic Institute of New York University (NYUPoly) partnering with researchers from the University of Pennsylvania and the University of Illinois at Urbana-Champaign, have devised a streamlined, minimally invasive brain interface that may yield new insights into the causes of brain diseases like epilepsy and could potentially lead to new implantable neuroprosthetic and diagnostic devices.

Biosensor May Improve Disease Detection

A new biosensor could rapidly and accurately detect early stage disease in very low concentrations. A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which could potentially help with early stage disease detection.

Harnessing the Power of Spinach

Vanderbilt University researches have developed a way to combine Photosystem 1 (PS1), the photosynthetic protein that converts light into electrochemical energy in spinach with silicon (the material used in solar cells), in a fashion that produces substantially more electrical current than has been reported by previous biohybrid solar cells.

New Approach to Graphene Electronics

Graphene has been touted as the next silicon, but it is too conductive to be used in computer chips. A University of Manchester team led by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.
