Startup creates drug toxicity app

October 29, 2013 7:47 am | Videos | Comments

Accurate and rapid testing for drug toxicity just became easier, thanks to a half-dozen Rice Univ. student interns working at Houston-based startup Nano3D Biosciences (n3D). The bioengineering and nanoscale physics students just wrapped up a year-long effort to aid the company in developing a new method for conducting high-throughput, in vitro cytotoxicity assays.

Neuroscientists discover new “mini-neural computer” in the brain

October 28, 2013 9:36 am | News | Comments

Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at the Univ. of North Carolina at Chapel Hill have shown that these dendrites do more than relay information from one neuron to the next. They actively process information, multiplying the brain's computing power.

“Anklebot” helps determine ankle stiffness

October 25, 2013 10:58 am | News | Comments

The act of walking is seldom given a second thought, but upon closer inspection locomotion is less straightforward. In particular, the ankle is an anatomical jumble, and its role in maintaining stability and motion has not been well characterized. A device called the “Anklebot” could help matters by measuring the stiffness of the ankle in various directions.

London uses van with x-ray machine to find TB

October 23, 2013 7:41 pm | by Maria Cheng, AP Medical Writer | News | Comments

Famed for its historic sites, its double-decker buses and its West End shows, London now has a more dubious distinction: Britain's public health agency says it has become the tuberculosis capital of Western Europe. In response, health officials are taking to the streets in an effort to stop the spread of the infectious lung disease.

Paper-based device could bring medical testing to remote locales

October 23, 2013 9:48 am | News | Comments

In remote regions of the world where electricity is hard to come by and scientific instruments are even scarcer, conducting medical tests at a doctor’s office or medical laboratory is rarely an option. Scientists are now reporting progress toward an inexpensive point-of-care, paper-based device to fill that void with no electronics required.

Separating the good from the bad in bacteria

October 17, 2013 7:39 am | by Jennifer Chu, MIT News Office | News | Comments

Massachusetts Institute of Technology researchers have developed a new microfluidic device that could speed the monitoring of bacterial infections associated with cystic fibrosis and other diseases. The new microfluidic chip is etched with tiny channels, each resembling an elongated hourglass with a pinched midsection. Researchers injected bacteria through one end of each channel, and observed how cells travel from one end to the other.

Finding blood clots before they wreak havoc

October 16, 2013 7:53 am | by Anne Trafton, MIT News Office | News | Comments

Life-threatening blood clots can form in anyone who sits on a plane for a long time, is confined to bed while recovering from surgery, or takes certain medications. There is no fast and easy way to diagnose these clots, which often remain undetected until they break free and cause a stroke or heart attack. However, new technology from Massachusetts Institute of Technology may soon change that.

IBM unveils two new Watson-related projects with Cleveland Clinic

October 15, 2013 9:40 am | News | Comments

Details have been released by IBM Research on Watson-related cognitive technologies that are expected to help physicians make more informed and accurate decisions faster and to cull new insights from electronic medical records (EMR). The new computing capabilities allow for a more natural interaction between physicians, data and EMRs.

Urine test could diagnose eye disease

October 9, 2013 11:54 am | News | Comments

You might not think to look to a urine test to diagnose an eye disease. But a new Duke Univ. study says it can link what is in a patient's urine to gene mutations that cause retinitis pigmentosa, or RP, an inherited, degenerative disease that results in severe vision impairment and often blindness.

Cell-detection system promising for medical research, diagnostics

October 3, 2013 8:33 am | News | Comments

Researchers are developing a system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient's blood, an advance that could help medical doctors diagnose cancer earlier than now possible and monitor how well a patient is responding to therapy.

Mass producing pocket laboratories

October 2, 2013 9:24 am | News | Comments

There is certainly no shortage of lab-on-a-chip devices, but in most cases manufacturers have not yet found a cost-effective way to mass produce them. Scientists are now developing a platform for series production of these pocket laboratories. The first major step is moving away from the usual injection molding or wet chemical processing techniques in favor of roll-to-roll processing.

Liquid biopsy could improve cancer diagnosis, treatment

October 1, 2013 8:27 am | News | Comments

A microfluidic chip developed at the Univ. of Michigan is among the best at capturing elusive circulating tumor cells from blood—and it can support the cells' growth for further analysis. The device, believed to be the first to pair these functions, uses the advanced electronics material graphene oxide. In clinics, such a device could one day help doctors diagnose cancers.

Scientists develop human-on-a-chip to research chemical warfare agent exposure

September 26, 2013 9:39 am | News | Comments

At the U.S. Army Edgewood Chemical Biological Center, experts have been conducting research of “organs” on microchips. Unlike the few other laboratories conducting these types of studies, the Army is specifically looking at potential scenarios that will affect warfighters, especially chemical agent exposure.

New study finds “microbial clock” may help determine time of death

September 25, 2013 9:04 am | News | Comments

An intriguing study led by the Univ. of Colorado Boulder may provide a powerful new tool in the quiver of forensic scientists attempting to determine the time of death in cases involving human corpses: a microbial clock. The clock is essentially the lock-step succession of bacterial changes that occur postmortem as bodies move through the decay process.

Microfluidic platform gives a clear look at a crucial step in cancer metastasis

September 20, 2013 1:31 pm | by Jennifer Chu, MIT News Office | News | Comments

Cancer cells metastasize in several stages—first by invading surrounding tissue, then by infiltrating and spreading via the circulatory system. Some circulating cells work their way out of the vascular network, eventually forming a secondary tumor. Now researchers have developed a microfluidic device that mimics the flow of cancer cells through a system of blood vessels. High-resolution time-lapse imaging captures the moment of metastasis.

August 27, 2013 2:43 pm | by Kurt Pfitzer, Lehigh Univ. | News | Comments

Standard drug-testing methods have shortcomings. Animal testing is expensive and unreliable, and the static environment of cells and cultures don’t mimic the behavior of the entire organism. An interdisciplinary research team at Lehigh Univ. is using microscopy and optical tweezers to develop a new finger-sized chip that can study the activities of cells at the nanoscale, possibly offering an alternative to traditional drug testing.

Microneedle patch could replace standard tuberculosis skin test

August 27, 2013 7:40 am | News | Comments

Each year, millions of people in the U.S. get a tuberculosis skin test to see if they have the infection. But the standard diagnostic test is difficult to give, because a hypodermic needle must be inserted at a precise angle and depth in the arm to successfully check for tuberculosis. Now, a team has created a microneedle patch that can penetrate the skin and precisely deliver a tuberculosis test.

New tool peeks into brain to measure consciousness

August 15, 2013 2:23 pm | by Lauran Neergaard, AP Medical Writer | News | Comments

When people have a brain injury so severe that they can't squeeze a loved one's hand or otherwise respond, there are few good ways to tell if they have any lingering awareness or are in a vegetative state. Now researchers have created a technique using a magnetic coil and an electroencephalogram to allow them to peek inside the brain and measure varying levels of consciousness.
