Researchers at NJIT have developed a safe and sustainable alternative to BPA in consumer products. The new epoxy resin is derived from corn starch and offers a renewable resource with estrogenic properties similar to BPA.
Researchers developed a microfluidic device that selectively isolates targeted cells, including cancer cells, based on their electrical properties. This breakthrough enables the screening of entire blood samples for cancer detection.
Case Western Reserve University scientist Dave Wilson has developed a cryo-imaging system that enables the identification of single molecules, counting of cells in organs, and comparison of normal and abnormal tissues. The system produces incredibly detailed images showing the effectiveness of different drug therapies.
Undergraduate researchers at UAB have developed a computer program that teaches CPR using hand-held remote controls from the Nintendo Wii video game console. The American Heart Association has pledged $50,000 to fund the project and make it available as an open source code download.
Researchers in India developed an X-ray image analysis technique that detects the early stages of tooth decay by analyzing X-ray wavelengths. This method could help save affected teeth and prevent tooth loss.
Researchers at Purdue University have created a needle-size device that can track tumors and provide real-time information on the radiation dose received. The device uses radio frequency identification technology and has the potential to improve treatment accuracy without exposing patients to damaging X-rays.
A recent study led by Howard Bassen found no electromagnetic interference from iPods on pacemaker users. Researchers tested four different iPod models and measured magnetic fields and voltages within pacemakers, with all results showing no effects.
The Oregon Health & Science University (OHSU) has received a $1 million grant from Intel to develop and test new technologies for monitoring cognitive function and mobility in older adults. The project aims to create innovative devices that can help prevent the loss of independence among seniors.
Two Yale Biomedical Engineers, Erin Lavik and Tarek Fahmy, have received Early Career Translational Research Awards for their innovative projects on glaucoma treatment and autoimmune disease diagnosis. The awards support their research collaborations with clinical investigators and provide two years of funding.
A team of students from Johns Hopkins University has developed a prototype that improves chest closure after heart surgery, replacing traditional metal wires with polymer cable ties. The device, which resembles a stapler, is designed to be safer and less invasive, reducing potential injuries to patients and surgeons.
Researchers at Yale University have developed a standardized method for synthesizing bulk nanowires, allowing for the exploration of next steps in semiconductor miniaturization. The new technology produces ten-times more nanowires than previous methods and sets parameters for standardization.
The Whitaker Foundation offers international fellowships and scholarships to US biomedical engineering students, aiming to provide an international outlook. The program will fund 15 years of fellowships and scholarships, with a focus on increasing interaction between US-educated engineers and overseas colleagues.
As people age, their lenses become four times stiffer, increasing the risk of eye injury. The study recommends using safety systems like seat belts while driving and wearing impact-resistant glasses or protective lenses in sports or work environments.
Biomedical engineers at Case Western Reserve University have developed a new, minimally invasive sensor that can accurately monitor glucose levels and other bodily fluids. The sensor, smaller than a pencil tip, uses color changes to detect glucose levels, providing diabetics with continuous monitoring capabilities.
Researchers have developed a new system to improve heart defibrillation by targeting rogue electrical waves in arrhythmia. The device produces milder shocks, reducing the amount of energy required, which could lead to smaller, longer-lasting devices that spare patients from frequent replacements.
University of Michigan researchers have developed an ultra-fast laser technique that enables precise nanoscale machining. The method uses femtosecond pulses to selectively ablate features as small as 20 nanometers, making it possible to machine a wide variety of materials on the nanometer scale.
Researchers at Vanderbilt University have discovered that groups of brain cells synchronize their electrical activity to enhance orientation discrimination. By studying the firing rates of dozens of neurons, scientists found that synchronization among six neurons can discriminate variations in orientation as small as two degrees. This ...
Researchers at Rutgers University have developed a bio-nano motor using virus-based proteins that can perform linear opening and closing motion. The tiny motor is small enough to line up with human hair, enabling potential use in systems for sensing temperature or position.
The Falk Center will utilize state-of-the-art gene chip technology to identify genes responsible for neurological disorders. Two therapeutic developments are approaching the product stage, including a gene-based therapy for malignant brain tumors and a treatment for attention deficit hyperactivity disorder.
A Rutgers biomedical engineering professor has discovered that cross-hand and one-hand grips can reduce eye movement during longer putts and head movement during shorter putts. The findings are part of a book exploring the physics, biomechanics, and physiology of various sports, including golf.
Researchers suggest that mechanical forces play a crucial role in shaping the developing heart, which could help scientists better understand heart defects. By studying the bending and rotation of chicken embryos, researchers have found that cellular contraction is driven by at least two different mechanical forces.
