Astrocytes are star‑shaped support cells that make up much of the brain’s structure, helping neurons communicate and maintaining the blood‑brain barrier. They are essential for healthy brain function, but scientists have struggled to study them because astrocytes lose their distinctive branching shapes when grown on flat glass dishes. Without their natural form, it has been difficult to understand how they behave or how they contribute to diseases such as Alzheimer’s and Parkinson’s. Researchers at Johns Hopkins University, working with colleagues in Italy, have solved this problem by creating mats of nanowires made from glass. These mats mimic the texture of…

Many gut problems are hard to catch because signs like bleeding or inflammation can come and go, and standard endoscopy might miss them. Scientists in China are developing swallowable capsules that contain harmless, engineered bacteria designed to act as tiny sensors inside the digestive tract. The idea is simple: the bacteria are programmed to react when they encounter certain clues linked to disease, such as blood components, inflammation markers, or chemical changes. When they detect these signals, the bacteria produce a response that the capsule’s electronics can read, turning a brief encounter into useful data for doctors. Because the capsule…

Strokes often begin with tiny blood clots forming inside damaged or irregular arteries, but it has been hard to watch those first moments in action. A University of Sydney team has built small, patient‑specific models of blood vessels that let researchers see how clots start and grow under lifelike conditions. They begin with medical scans from real patients and use those as blueprints to create miniature versions of the carotid artery, the vessel in the neck that supplies blood to the brain. These printed vessels are made directly on glass, which helps blood flow more naturally through them during tests.…

A new advance from the University of California, Riverside has produced the first fully synthetic brain tissue model, designed to eliminate reliance on animal-derived materials and provide a reproducible platform for studying neurological diseases. Traditional brain tissue models often depend on biological coatings such as laminin or fibrin to help cells survive, but these coatings are inconsistent and difficult to replicate. Rodent brains have also been used as stand-ins for human conditions, yet genetic and physiological differences limit accuracy. The UC Riverside innovation addresses these challenges by creating a synthetic scaffold that supports functional brain-like tissue without animal materials, aligning…

Lung cancer remains one of the most difficult cancers to diagnose early, largely because tumors often form in the peripheral regions of the lung where conventional bronchoscopes cannot reach. While CT scans can detect small lesions, obtaining a biopsy or delivering treatment has been a major challenge. The bronchi become narrower and more complex toward the periphery, forcing clinicians to stop several centimeters short of the target. This limitation has hindered both accurate diagnosis and minimally invasive treatment options. A new technique developed at Osaka University offers a solution by using balloon-assisted bronchoscopy to safely widen the airway and create…

Researchers at Texas A&M University have introduced a biodegradable microneedle patch designed to help the heart heal after a heart attack. Heart attacks deprive cardiac muscle cells of oxygen, causing them to die. The body responds by forming scar tissue, which stabilizes the heart but cannot contract like healthy muscle. This forces the remaining tissue to work harder, often leading to heart failure. The Texas A&M innovation aims to change this trajectory by delivering immune-modulating molecules directly to damaged tissue, creating a healing environment at the site of injury. The patch uses a microneedle system that penetrates the outer layer…

South Korean beauty company Amorepacific has been recognized as a CES 2026 Innovation Award Honoree for its advanced electronic skin platform, Skinsight, developed in collaboration with researchers at MIT. This achievement highlights the company’s leadership in beauty technology and marks its seventh consecutive CES Innovation Award, underscoring a consistent track record of innovation in the intersection of science, technology, and skincare. Skinsight is designed as a next-generation wearable system that functions like electronic skin. The platform consists of three integrated components: an ultra-thin sensor patch, a compact Bluetooth transmission module, and an AI-powered mobile application. Together, these elements allow users…

MIT researchers have unveiled a groundbreaking injectable antenna that could transform how medical implants are powered deep inside the human body. Traditional implants such as pacemakers or neuromodulators rely on bulky batteries or require invasive surgery for placement and maintenance. These approaches carry risks including infection, tissue damage, and repeated surgical interventions. The new antenna, developed by Associate Professor Deblina Sarkar and her group at the MIT Media Lab’s Nano-Cybernetic Biotrek, offers a safer and more efficient alternative by enabling battery-free implants that can be delivered through a simple injection. The device is a magnetoelectric antenna smaller than a grain…

A team at ETH Zurich has unveiled magnetic microrobots designed to deliver drugs directly to targeted sites in the human body, offering new possibilities for treating strokes, infections, and tumors. This innovation addresses a critical medical challenge: every year, millions of patients suffer strokes, and current therapies require high systemic doses of clot‑dissolving drugs that can cause severe side effects. By guiding medication precisely to the blocked vessel, the ETH Zurich microrobots promise safer and more effective treatment. The microrobots are engineered as spherical capsules with a soluble gel shell. Embedded within the shell are iron oxide nanoparticles that allow…

Researchers at the University of Colorado Boulder have introduced a breakthrough surgical device that is transforming hip arthroscopy by making procedures safer, faster, and more effective. Hip arthroscopy is a minimally invasive surgery used to diagnose and treat joint problems, but traditional tools often limit precision and increase surgical time. The newly developed cannula device, formally named the CAP-LIFT cannula, provides surgeons with improved access to the hip joint, reducing complications and streamlining operations. Traditional cannulas used in hip arthroscopy often require multiple adjustments and can be difficult to position. This increases surgical time and risk, especially in complex procedures.…
