MIT engineers designed polymer microparticles that can deliver vaccines at predetermined times after injection.

Now, in ACS Applied Materials & Interfaces, researchers report a dental floss pick with a built-in sensor that could monitor stress as part of a daily routine. The device, which accurately senses levels of the stress hormone cortisol in minutes, could help users recognize when it’s time to get help.

A joint research team affiliated with UNIST has developed a 3D-printed artificial tumor tissue capable of replicating the in vivo conditions of patient-derived cancer cells. This innovative model not only simulates the tumor microenvironment but also integrates artificial intelligence (AI) technology that can predict patient prognosis solely from images of tumor growth.

Researchers at UCL and the Francis Crick Institute have, for the first time, identified the origin of cardiac cells using 3D images of a heart forming in real-time, inside a living mouse embryo.

University of California, Los Angeles and University of California, San Diego researchers developed an injectable sealant for rapid hemostasis and tissue adhesion in soft, elastic organs.

Yale researchers have built a 3D-bioprinted synthetic aorta that they have successfully implanted into rats. This technology could advance the treatment of cardiovascular diseases such as coronary artery disease or peripheral arterial disease by allowing scientists to engineer and replace blood vessels in humans.

A new probiotic could soon tackle the burden of heavy-metal-contaminated fish.

The future of electroencephalography (EEG) monitoring may soon look like a strand of hair. In place of the traditional metal electrodes, a web of wires and sticky adhesives, a team of researchers from Penn State created a hairlike device for long-term, non-invasive monitoring of the brain’s electrical activity. The lightweight and flexible electrode attaches directly to the scalp and delivers stable, high-quality recordings of the brain’s signals.
