A team at the University of California, Irvine has created a three-dimensional artificial colon that closely replicates the structure and behavior of human colon tissue. This innovation combines biological materials with embedded electronics to simulate real-time responses to disease and drug treatments. The model is designed to support research into colorectal cancer, inflammatory bowel disease, and other gastrointestinal conditions, while also enabling personalized medicine approaches. The artificial colon, referred to as the 3D in vivo mimicking human colon, measures approximately 5 by 10 millimeters and includes key anatomical features such as curved surfaces, layered cell structures, and cryptlike indentations. These…

A team from the Laboratory for Advanced Fabrication Technologies at École Polytechnique Fédérale de Lausanne (EPFL) has created a miniature device called the Magnetic Endoluminal Deposition System, or MEDS, which functions as a pill-sized bioprinter. Once swallowed, MEDS can be guided through the digestive system using external magnets and activated by a near-infrared laser to release bio-ink directly onto internal wounds such as ulcers or hemorrhages. This approach could eliminate the need for invasive surgery and anesthesia, which are currently required to treat many gastrointestinal injuries. The device is designed like a tiny ballpoint pen. It contains a chamber filled…

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…
