Chemists at Stanford University have developed a non-invasive technique using lasers and carbon nanotubes that visualizes blood flow in the brain, which could help provide powerful insights into strokes and possibly Alzheimer's disease. Current non-invasive technologies like CT scans or MRI visualize...

A team of engineers at The University of Texas (UT) at Austin have designed an optical device that, they say, may offer a fast, comprehensive, noninvasive, and lower-cost solution to detect melanoma and other skin cancer lesions, thereby reducing unnecessary biopsies. Their device is a probe that uses light in...

The race is on to design smaller, cheaper, and more efficient rechargeable batteries to meet power storage needs. Now, a team of researchers at Stanford University report that they have taken a big step toward designing a pure lithium anode, which, they say, would greatly advance current lithium ion batteries.

UL (Underwriters Laboratories), Northbrook, IL, announced that the FDA has recognized two UL battery safety standards as consensus standards for medical devices incorporating lithium or nickel-based batteries. The two standards are UL 2054 - Standard for Household and Commercial...

A research team at the Cockrell School of Engineering at The University of Texas at Austin has created a new nonlinear metasurface, or meta mirror, that may help advance the miniaturization of laser systems for biomedical research and other applications.

A collaboration between researchers at Penn State University, and Shinshu University in Japan say that they have developed a simple, scalable method of making graphene oxide (GO) fibers that are strong, stretchable, and can be easily crolled into yarn with strengths approximating that of Kevlar.

Scientists at Lawrence Livermore National Laboratory (LLNL) recently received $5.6 million from the Department of Defense's Defense Advanced Research Projects Agency (DARPA) to develop an implantable neural interface that can record and stimulate neurons within the brain to treat neuropsychiatric...

Scientists at the Rochester Institute of Technology, Rochester, NY, are developing imaging software that, they say, could give radiologists a tool to measure the growth of nodules in patients at risk of lung cancer. In a two-year study, Nathan Cahill, an associate professor in RIT’s School of...

Digital printing technologies play an important role in microelectronics, microsystems engineering, and sensor systems. Recently, scientists at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Bremen, Germany, have discovered that they can use...

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory, Berkeley, CA, say that they have demonstrated a technique for producing, detecting, and controlling ultrahigh frequency sound waves at the nanometer scale. Through a combination of...

Using precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan, Ann Arbor, researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. They say that their first-time polariton laser is fueled by...

A team of biomedical engineering students at Johns Hopkins University, Baltimore, MD, designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is...

The NIH’s Bionic Man site helps viewers visually explore some of the latest bioengineering creations from research funded by the National Institute of Biomedical Imaging and Bioengineering. From prosthetics to artificial kidneys, these technologies are changing lives now and in the future.

Researchers at the National Institute of Standards and Technology (NIST), Gaithersburg, MD, say that they have built and demonstrated a chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging. The new microfluidic chip produces polarized (or...

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee say they have developed a new type of battery chemistry aimed at producing batteries that last longer than previously thought possible.

Move over Iron Man! There’s a new engineering superhero who’s part bionic, able to change his height, and scale vertical rock and ice walls with a simple change of leg prosthetics that he designed himself. Not only that, but he designs bionic limbs for others, too.
