TV game show Jeopardy! challenges even the best human minds. Can a computer win at Jeopardy!? Aired February 9, 2011 on PBS.
A low-cost smartphone accessory that can detect three infectious disease markers from a finger prick of blood in just 15 minutes, performing all mechanical, optical, and electronic functions of a lab-based blood test.
Ramesh Raskar of the Camera Culture group at MIT has devised a method of providing basic eye tests using just a smartphone and a specially designed eyepiece.
It could provide a home-based eye test for millions of people who cannot easily access regular optometry services.
Worcester Polytechnic Institute (WPI) researchers have developed a smart phone app that can measure heart rhythm and rate, respiration rate, and blood oxygen saturation using the phone’s built-in video camera.
As the camera’s light penetrates the skin, it reflects off pulsing blood in the finger. The app can correlate subtle shifts in the color of the reflected light with changes in the patient’s vital signs.… read more
Trimensional works using an iPhone’s screen, for example, to shine four different lighting patterns on a subject while also using the front-facing camera to snap photos. It produces a full… read more
This is an app and medical sensor that turns a non-specialist, community-level health worker’s smartphone, tablet computer or laptop into an affordable and simple but sophisticated medical-grade diagnostic tool that is typically only available, in the developing world, in some hospitals.

Researchers at Massachusetts General Hospital in Boston have developed a system that can detect tumors by analysing a few thousands cells, sparing patients from the larger biopsies currently used.
The palm-sized device sits on the patient’s bedside table, operated through a simple smartphone app. At the core is a micro nuclear magnetic resonance (microNMR) chip, a scaled-down version of the technology found in magnetic resonance imaging (MRI) scanners. It… read more
University of Michigan computer scientists have developed a new “subconscious mode” for smartphones and other WiFi-enabled mobile devices that could extend battery life by as much as 54 percent for users on the busiest networks. It’s called E-MiLi (Energy-Minimizing Idle Listening).
Even when smartphones are in power-saving modes and not actively sending or receiving messages, they are still on alert for incoming information and they’re… read more
Researchers at the Technical University of Denmark have demonstrated a fully functional smartphone brain scanner — consisting of a low-cost 14-channel EEG headset with a wireless connection to a smartphone (Nokia N900) — enabling minimally invasive EEG monitoring in real-world settings.
The system provides a fully portable EEG based real-time functional brain scanner, sensors, data acquisition, logging, brain state decoding, and 3D activity visualization.… read more
“Essentially what this means is that telemedicine can fit in our pockets,” says Bart Demaerschalk, M.D., professor of Neurology, and medical director of Mayo Clinic Telestroke.
“For patients this means access to expertise in a timely fashion when they need it… read more
DARPA’s Adaptable Sensor System (ADAPT) program aims to transform how unattended sensors are developed for the military by using a manufacturing process similar to that of the commercial smartphone industry.
The goal is to develop low-cost, rapidly updatable intelligence, surveillance and reconnaissance (ISR) sensors in less than a year, a marked improvement to the current three-to-eight year development process.
The unattended ground… read more
A smartphone-based device developed by Harvard Medical School investigators at Massachusetts General Hospital could bring rapid, accurate molecular diagnosis of cancer and other diseases to locations lacking the latest medical technology.
The device uses technology for making holograms to collect detailed microscopic images for digital analysis of the molecular composition of cells and tissues.
“The global burden of cancer, limited access to prompt pathology… read more
Smartphones distracted students from school-related tasks in self-reported results of a one-year study of first-time smartphone users at a major research university in Texas.
“Smartphone technology is penetrating world markets and becoming abundant in most college settings,” said Philip Kortum, assistant professor of psychology at Rice and the study’s co-author. “We were interested to see how students with no prior experience using smartphones thought [smartphones] impacted their education.”
The… read more
