“Artificial nose” speeds sepsis diagnosis

http://phys.org/news/2013-09-artificial-nose-device-diagnosis-sepsis.html Researchers at the National University of Kaohsiung in Taiwan and the University of Illinois have developed an “artificial nose” capable of detecting the odor of germs that lead to blood poisoning.  Within 24 hours it determines whether a patient’s blood has bacteria that cause sepsis, a gain of up to two days over conventional methods.

Human-to-human brain interface – UW researcher controls colleague’s movement

http://www.washington.edu/news/2013/08/27/researcher-controls-colleagues-motions-in-1st-human-brain-to-brain-interface/ University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other […]

Eliminating sugar slows cancer growth

http://www.scotsman.com/news/health/cutting-off-sugar-could-stop-cancer-growth-1-3024411 Old but important news: Eliminating sugar can slow cancer growth. Researchers were aware that all cancer cells are attracted to sugar, grabbing it from the blood before using it to fuel their growth.  In breast cancer the process involves binding proteins called CtBPs together to form pairs known as dimers. These in turn help […]

Piezo-Phototronic LEDs may help robots feel

http://www.nature.com/nphoton/journal/vaop/ncurrent/full/nphoton.2013.191.html In a related development to Berkeley’s touch responsive e skin, Georgia Tech Professor Zhong Lin Wang  has proposed a new “piezo-phototronic” approach to the human-machine interface.  Zinc-oxide nanowires serve as tiny LEDs which have an emission intensity dependent on the local strain put on them.  The nanowire array could act as artificial skin for robots to […]

Angel Health Monitor – Open platform, wearable vital sign sensors

http://www.angelsensor.com/index.html The Angel Health Monitor is an open platform and SDK that senses motion and acceleration, skin temperature, blood oxygen saturation, and heart rate.  It was created by Eugene Jorov in Israel and will launch a crowdfunding campaign soon.  Developers will be able to use Angel to create apps for iPhone, Android, and other devices […]

Brain-like computing from IBM

http://www-03.ibm.com/press/us/en/pressrelease/41710.wss IBM is planning a a brain-inspired model for a new generation of highly-interconnected, asynchronous, parallel and large-scale computing systems based around the concept of cognitive computing.  It is an ecosystem designed for programming neurosynaptic chips that have an architecture inspired by the function, low power, and compact volume of the brain Cognitive computing systems can be […]

Sensor based continuous monitoring helps doctors individualize treatment

http://www.theengineer.co.uk/medical-and-healthcare/in-depth/tailored-treatments-sensors-for-personalised-medicine/1016865.article Doctors are still dependant on single point-in-time measurements of factors such as blood glucose and hormone levels, which do not show how these factors dip or rise into danger zones over the course of a day.   Similarly, monitoring heart rates over time in a hospital does not always show the physical responses caused […]

Computer model reprograms cells

http://onlinelibrary.wiley.com/doi/10.1002/stem.1473/abstract Professor Antonio del Sol of the Luxembourg Centre for Systems Biomedicine has developed a model that makes predictions from which differentiated cells, such as skin cells, can be very changed into completely different cell types, such as nerve cells.  Embryonic stem cells are not used.  Researcher Issac Crespo describes the process: “Our theoretical model first queries […]

Insulin pump detects overnight hypoglycemia, shuts off automatically

http://www.bloomberg.com/news/2013-06-22/medtronic-insulin-pump-cuts-deadly-night-blood-sugar-lows.html Medtronic has designed an insulin pump that temporarily shuts off when blood sugar levels fall too low—a key advance in the effort to fully automate the delivery of insulin in diabetes patients.  Current technology allows people who use insulin pumps to wear a sensor that measures the amount of blood sugar in the body, which […]

Artificial spleen-on-a-chip to treat sepsis

http://wyss.harvard.edu/viewpressrelease/108/ Harvard researchers are developing a device that could be used to rapidly remove pathogens from the blood of patients with sepsis.  The dialysis-like machine acts as an artificial spleen, filtering the blood using injectable magnetic nanobeads engineered to stick to microorganisms and toxins.  After the beads are injected, blood is removed and run through a […]
