Separating circulating cancer cells from blood cells for diagnostic, prognostic and treatment purposes may become much easier using an acoustic separation method and an inexpensive, disposable chip, according to a team of engineers from Penn State Univ.
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.
Calico, a company whose mission is to harness advanced technologies to increase understanding of the biology that controls human lifespan, and UC San Francisco have partnered on an innovative project to develop potential therapies for cognitive decline.
Scientists have developed tiny nanoneedles that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice. The researchers, from Imperial College London and Houston Methodist Research Institute, hope their nanoneedle technique could ultimately help damaged organs and nerves to repair themselves and help transplanted organs to thrive.
Employing an ingenious microfluidic design that combines chemical and mechanical properties, a team of Harvard Univ. scientists has demonstrated a new way of detecting and extracting biomolecules from fluid mixtures. The approach requires fewer steps, uses less energy, and achieves better performance than several techniques currently in use and could lead to better technologies for medical diagnostics and chemical purification.
Acne, a scourge of adolescence, may be about to meet its ultra-high-tech match. By using a combination of ultrasound, gold-covered particles and lasers, researchers from Univ. of California, Santa Barbara and Sebacia have developed a targeted therapy that could potentially lessen the frequency and intensity of breakouts, relieving acne sufferers the discomfort and stress of dealing with severe and recurring pimples.
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.
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.
Engineers at Oregon State Univ. have used additive manufacturing to create an improved type of glucose sensor for patients with Type 1diabetes, part of a system that should work better, cost less and be more comfortable for the patient. A key advance is use of electrohydrodynamic jet, or “e-jet” printing, to make the sensor.
A big federal study finds that people who see a doctor for chest pain have no less risk of suffering a heart attack, dying or being hospitalized later if they are checked with a fancy newer type of CT scan rather than a simple treadmill test or other older exam. CT scans, a type of x-ray that gives a very detailed look at heart arteries, have been used for about a decade without evidence they are better or worse than older tests.
A sophisticated necklace developed by researchers at the Univ. of California, Los Angeles, can monitor food and drink intake, which could help wearers track and improve their dietary habits. The inventors of the WearSens device say it could help battle obesity, heart disease, diabetes and other problems related to nutrition.
Researchers at Massachusetts Institute of Technology have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles: a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
Federal health officials are stepping up their oversight of medical scopes linked to potentially fatal "superbug" outbreaks. The Food and Drug Administration released stricter guidelines for manufacturers of reusable medical instruments, including specialized endoscopes used in about a half-million U.S. medical procedures each year.
Three-dimensional bioprinting has come a long way since its early days when a bioengineer replaced the ink in his desktop printer with living cells. Scientists have since successfully printed small patches of tissue. Could it someday allow us to custom-print human organs for patients in need of transplants?
The editors of R&D Magazine have announced an eligibility extension for products to be entered into the 2015 R&D 100 Awards. The 2015 R&D 100 Awards will honor products, technologies and services that have been introduced to the market between January 1, 2014 and March 31, 2015.
Most military battlefield casualties die before ever reaching a surgical hospital. Of those soldiers who might potentially survive, most die from uncontrolled bleeding. In some cases, there’s not much medics can do. That’s why Univ. of Washington researchers have developed a new injectable polymer that strengthens blood clots, called PolySTAT.
This professor carries out pioneering work in the creation of biological circuits.
It’s been “known” for decades: Sensory, motor and cognitive signals come in from the brain’s cortex and are processed in the basal ganglia.
A new simple tool developed by nanoengineers at the Univ. of California, San Diego, is opening the door to an era when anyone will be able to build sensors, anywhere. The team developed high-tech bio-inks that react with several chemicals, including glucose. They filled off-the-shelf ballpoint pens with the inks and were able to draw sensors to measure glucose directly on the skin and sensors to measure pollution on leaves.
Current peanut allergy tests are not very reliable when it comes to diagnosing the severity of an individual’s allergic reaction, which can range from hives to life-threatening anaphylactic shock. With an estimated three million people in the U.S. allergic to peanuts and tree nuts, having a more precise and reliable allergy test could prevent hospitalizations and allow for better monitoring of individuals suffering from peanut allergies.
Scientists around the world make use of cell culture techniques on a daily basis. Whether they happen to be working with primary cell cultures, secondary cultures or cell lines, they all face many of the same problems: slow growth, spontaneous differentiation, evaporation, contamination and a host of other issues that require troubleshooting.
When diagnosing a case of Ebola, time is of the essence. However, existing diagnostic tests take at least a day or two to yield results, preventing health care workers from quickly determining whether a patient needs immediate treatment and isolation. A new test could change that: The device, a simple paper strip similar to a pregnancy test, can rapidly diagnose Ebola, as well as other viral hemorrhagic fevers.
Univ. of Tokyo researchers have developed a "fever alarm armband," a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in health care settings.
Electrical impulses play an important role in cells of the human body. For example, neurons use these impulses to transmit information along their branches and the body also uses them to control the contraction of muscles. The impulses are generated when special channel proteins open in the outer envelope of the cells, allowing charged molecules (ions) to enter or exit the cell. These proteins are referred to as ion channels.
An estimated 285 million people are visually impaired worldwide. Age-related macular degeneration alone is the leading cause of blindness among older adults in the Western world. However, Eric Tremblay from EPFL in Switzerland unveiled a new prototype of his telescopic contact lens, giving hope for better, stronger vision.
