Researchers at Pohang University of Science and Technology (POSTECH) in Korea have created a bioadhesive sponge that can rapidly stop internal bleeding, especially in high-risk surgeries involving organs like the liver or spleen. The sponge combines mussel adhesive protein with decellularized extracellular matrix (dECM) to provide strong tissue adhesion and support wound healing. Traditional hemostatic agents often fail to stick to wet tissue or degrade properly, leading to complications. The POSTECH sponge addresses these issues by adhering firmly to bleeding sites and activating the body’s natural clotting mechanisms. Once bleeding is controlled, the sponge biodegrades safely, while the dECM promotes…

Engineers at Carnegie Mellon University have developed a customizable finger brace that uses 3D printing and embedded sensors to support recovery from hand injuries. The brace is designed to be lightweight, adjustable, and responsive to individual needs, making it suitable for a wide range of rehabilitation scenarios. The device includes soft actuators and sensors that monitor finger movement and provide feedback during recovery. Patients can wear the brace while performing exercises, and the sensors track progress in real time. This data can be shared with therapists to adjust treatment plans and ensure proper healing. One of the key features of…

A team at Penn State has developed a skin-mounted sensor that can detect vitamin B6 and glucose in sweat, offering a non-invasive way to monitor key health markers. This technology could be especially useful for people with chronic conditions like diabetes, who often experience low vitamin B6 levels and need regular glucose monitoring. Vitamin B6 plays a vital role in immune function and brain health, but current methods for measuring it require expensive and invasive blood tests. The new sensor uses laser-induced graphene nanocomposites combined with molecularly imprinted polymers (MIPs) to selectively bind and detect vitamin B6 molecules. These MIPs…

Researchers at Concordia University have developed a new microchip that can monitor brain activity related to Alzheimer’s disease in real time. This technology could help scientists better understand how the disease progresses and lead to earlier and more accurate diagnoses. Alzheimer’s disease is a complex condition that affects memory, thinking, and behavior. It develops gradually, often over many years, and is difficult to study because traditional tools only provide snapshots of brain activity. The new chip developed at Concordia changes that by offering continuous monitoring of the brain’s electrical signals and chemical markers. The chip is designed to detect specific…

Researchers at North Carolina State University have developed a more accurate way to detect coughing using wearable health monitors. This innovation could improve how doctors monitor chronic respiratory conditions like asthma and help track symptoms of infectious diseases such as COVID-19 or the flu. Traditional cough detection systems rely mostly on audio recordings. However, these systems often misidentify other sounds, such as speech, sneezes, or throat clearing, as coughs. This leads to false positives and limits the usefulness of the technology in real-world environments. To address this, the NC State team created a system that combines audio data with motion…

A pilot study led by researchers at Goethe University Frankfurt and Münster University Hospital has shown that deep brain stimulation (DBS) can significantly reduce stuttering in patients with severe speech flow disorders. The team implanted a thin electrode into the left thalamus of a patient with persistent developmental stuttering and used mild electrical pulses to stimulate the brain region over several months. The results were striking. The patient’s stuttering frequency dropped by 46 percent, and the severity of episodes decreased. When the stimulation was turned off without the patient’s knowledge, his stuttering worsened again, confirming the biological impact of the…

Scientists at the University of Massachusetts, Amherst have created a new type of cancer vaccine that successfully prevents tumors and stops cancer from spreading in mice. The vaccine uses tiny particles called nanoparticles to train the immune system to recognize and destroy cancer cells before they can grow or spread. Led by biomedical engineer Prabhani Atukorale, the research team tested the vaccine on three aggressive types of cancer: melanoma, pancreatic cancer, and triple-negative breast cancer. In one study, mice received the vaccine and were later exposed to melanoma cells. Most of the vaccinated mice, about 80 percent, remained healthy and…

Researchers at the University of Rochester have developed a brain-on-a-chip platform that models how diseases such as sepsis and neurodegenerative conditions damage the blood-brain barrier. This barrier protects the brain from harmful substances in the bloodstream, and its breakdown can lead to serious neurological complications. The new platform allows scientists to observe how inflammation and disease-related stress signals weaken this barrier and trigger harmful changes in brain cells. The device uses human tissue embedded in microchips to simulate the structure and function of the blood-brain barrier. Researchers introduced cytokine storms—intense immune responses often seen in severe infections—and observed how they…

Researchers at the University of Waterloo have developed a contactless radar system that uses artificial intelligence to monitor subtle changes in a person’s health. Unlike wearable devices that require physical contact or regular charging, this system operates remotely by analyzing how radio waves bounce off the human body. It can detect small shifts in movement, breathing, and other physiological signals, offering a noninvasive way to track health over time. The radar system works by sending low-power radio signals toward a person and interpreting the reflections using machine learning algorithms. These reflections contain detailed information about body motion, including patterns that…

Understanding how the brain works during real-life behavior has long been a challenge for neuroscientists. Researchers at the University of Washington have developed a powerful new neural probe that records activity across multiple brain regions while animals are freely moving. This tool allows scientists to observe how different circuits interact during tasks like decision-making, movement, and social interaction. The probe is made from ultra-thin, flexible materials that minimize damage to brain tissue and allow for long-term recordings. It contains hundreds of electrodes arranged to capture signals from deep and surface-level structures simultaneously. In tests with mice, the device recorded detailed…
