Revealing security flaws in teleoperated surgical robots

May 8, 2015 8:17 am | by Jennifer Langston, Univ. of Washington | News | Comments

To make cars as safe as possible, we crash them into walls to pinpoint weaknesses and better protect people who use them. That’s the idea behind a series of experiments conducted by a Univ. of Washington engineering team who hacked a next-generation teleoperated surgical robot to test how easily a malicious attack could hijack remotely controlled operations in the future and to make those systems more secure.

VEST helps deaf feel, understand speech

April 9, 2015 9:59 am | by Mike Williams, Rice Univ. | Videos | Comments

A vest that allows the profoundly deaf to “feel” and understand speech is under development by engineering students and their mentors at Rice Univ. and Baylor College of Medicine. Under the direction of neuroscientist David Eagleman, Rice students are refining a vest with dozens of embedded actuators that vibrate in specific patterns to represent words. The vest responds to input from a phone app that isolates speech from ambient sound.

How do you feel? Video of your face may tell all

April 7, 2015 7:42 am | by Mike Williams, Rice Univ. | Videos | Comments

Rice Univ. researchers are developing a highly accurate, touch-free system that uses a video camera to monitor patients’ vital signs just by looking at their faces. The technique isn’t new, but engineering researchers in Rice’s Scalable Health Initiative are making it work under conditions that have so far stumped earlier systems.

Facebook app encourages individuals to get in touch with their DNA

April 1, 2015 7:48 am | by Laurel Thomas Gnagey, Univ. of Michigan | News | Comments

Have you ever wondered if your dad's fight with prostate cancer means you could face the same reality? Perhaps your family has several members who have struggled with obesity and you wonder if it's something you inherited or if it's caused by the environment. Maybe you have always wanted to learn where your ancestors came from beyond the basic paper trail. Good news: Researchers have an app for that.

Minimal device maximizes macula imaging

March 18, 2015 7:49 am | by Mike Williams, Rice Univ. | Videos | Comments

A smart and simple method developed at Rice Univ. to image a patient’s eye could help monitor eye health and spot signs of macular degeneration and diabetic retinopathy, especially in developing nations. The patient-operated, portable device invented at Rice is called mobileVision. It can be paired with a smartphone to give clinicians finely detailed images of the macula, without artificially dilating the pupil.

“Smart bandage” detects bed sores before they are visible

March 17, 2015 2:23 pm | by Sarah Yang, Univ. of California, Berkeley | Videos | Comments

Engineers at the Univ. of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes, and while recovery is still possible.

Wearable sensor clears path to long-term EKG, EMG monitoring

January 20, 2015 10:16 am | by Matt Shipman, News Services, North Carolina State Univ. | News | Comments

Researchers from North Carolina State Univ. have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.

Technology advances eye tracking as biomarker for brain function

December 16, 2014 3:19 pm | by Stacey Harris, NYU Langone Medical Center | News | Comments

Researchers at NYU Langone Medical Center have developed new technology that can assess the location and impact of a brain injury merely by tracking the eye movements of patients as they watch music videos for less than four minutes, according to a study published online in the Journal of Neurosurgery.

Sound-powered chip to serve as medical device

October 17, 2014 9:18 am | by Tom Abate, Stanford Engineering | News | Comments

Medical researchers would like to plant tiny electronic devices deep inside our bodies to monitor biological processes and deliver pinpoint therapies to treat illness or relieve pain. But so far engineers have been unable to make such devices small and useful enough. Providing electric power to medical implants has been one stumbling block. Using wires or batteries to deliver power tends to make implants too big, too clumsy—or both.

“Smart” bandage emits phosphorescent glow for healing below

October 1, 2014 9:37 am | News | Comments

Inspired by a desire to help wounded soldiers, an international team has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Because oxygen plays a critical role in healing, mapping these levels in severe wounds and burns can help to greatly improve the success of surgeries to restore limbs and physical functions.

Magnetic field opens and closes nanovesicle

September 24, 2014 9:18 am | Videos | Comments

Researchers in the Netherlands have managed to open nanovesicles in a reversible process and close them using a magnet. Previously, these vesicles had been “loaded” with a drug and opened elsewhere using a chemical process, such as osmosis. The magnetic method, which is repeatable, is the first to demonstrate the viability of another method.

Program predicts placement of chemical tags that control gene activity

September 22, 2014 9:20 am | by Susan Brown, Univ. of California, San Diego | News | Comments

Biochemists in California have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. By comparing sequences with and without epigenomic modification, the researchers identified DNA patterns associated with the changes. They call this novel analysis pipeline Epigram and have made both the program and the DNA motifs they identified openly available to other scientists.
