Smartphone brain scanner

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

A new Mayo Clinic study confirms the use of smartphones medical images to evaluate stroke patients in remote locations through telemedicine.

“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

Smartphone technology inspires design for smart unattended ground sensor

May 30, 2013

ADAPT_DARPA

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

Smartphone training helps people with memory impairment regain independence

February 9, 2012

Baycrest  neuropsychologists have found that a smartphone training program, theory-driven and specifically designed for individuals with memory impairment, can result in “robust” improvements in day-to-day functioning, and boost independence and confidence levels.

“The goal of our study was to demonstrate the generalizability of our training protocol to a larger number of individuals with moderate-to-severe memory impairment,” said Dr. Eva Svoboda, a clinical neuropsychologist in the Neuropsychology… read more

Smartphone-based device could provide rapid, low-cost molecular tumor diagnosis

April 14, 2015

SmartphoneDiagnosis-ft

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 more accurate, faster, cheaper for disease surveillance

March 14, 2012

Smartphones are showing promise in disease surveillance in the developing world.

Smartphone use was cheaper than traditional paper survey methods to gather disease information (after the initial set-up cost), researchers at the Kenya Ministry of Health and the U.S. Centers for Disease Control and Prevention, found in a study.

Survey data collected with smartphones also had fewer errors and were more quickly available for analyses… read more

Smartphones not so smart for learning?

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.”

Smartphoniacs: Addicts of the Information Age

July 10, 2009

The top 10% of smart-phone users — the smartphoniacs — are the true addicts of the information age.

You might be a smartphoniac if you:

- Take your smartphone to the restroom
- Send messages while driving
- Sneak a look at your messages during a conversation
- Suffer from sprained or elongated thumbs
- Openly use your smart phone in inappropriate places, such as first dates

Smell cannon targets virtual reality users

April 2, 2004

A new “air cannon” device can track an individual, shoot an aroma directly at their nose, and leave the person next to them completely unaffected.

Advanced Telecommunications Research Institute in Kyoto, Japan developed it for directing evocative smells to people exploring virtual-reality environments.

The device tracks the person it is aiming at with a camera mounted on top, which follows the target’s eyes. Software on a PC analyzes… read more

Smell-o-Vision is finally here

April 1, 2013

Smell-O-Vision was a system that released odors during the projection of a film so that the viewer could “smell” what was happening in the movie.

Now the “smelling screen,” invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee,… read more

Smile, Gamers: You’re in the Picture

The Smithsonian is using laser scanners and 3D printers to create “digital surrogate” models, exhibits, and scientific replicas of many of 137 million physical objects in its collection.

The museum also hopes to make its digital 3D models publicly available.

 

Smoking leaves ‘footprint’ in DNA

Findings could provide researchers with potential targets for new therapies

Smoking leaves its “footprint” on the human genome in the form of DNA methylation, a process that affects what genes are turned on, according to new research in Circulation: Cardiovascular Genetics, an American Heart Association journal.

The new findings could provide researchers with potential targets for new therapies.

“These results are important because methylation, as one of the mechanisms of the regulation of gene expression, affects… read more

Smoking ‘triggers deadly changes’

May 15, 2008

Oregon Health and Science University researchers have identified a key mechanism by which smoking triggers genetic changes that cause lung cancer.

Cigarette smoke slows production of the FANCD2 protein in lung cells. FANCD2 plays a key role in repairing damage to DNA and causes faulty cells to commit suicide before they go on to become cancerous.

Snake design inspires improved search-and-rescue robots

January 23, 2012

scalybot

Georgia Tech researchers have designed a new all-terrain robot by studying the locomotion of snakes.

Designing an all-terrain robot for search-and-rescue missions requires a machine that is flexible enough to move over uneven surfaces, yet not so big that it’s restricted from tight spaces.

It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but… read more
