Periodontitis – an advanced form of gum disease that breaks down tissue and bones housing the teeth – affects more than 70 percent of adults aged 65 and older. Engineers have devised various ways to combat the issue, ...
A diagnostic tool, similar in theory to those used by the medical profession to non-invasively image internal organs, bones, soft tissue, and blood vessels, could be equally effective at "triaging" extraterrestrial rocks ...
For an illness like cancer, doctors often turn to computed tomography (CT) scans for a more definitive diagnosis, based on reconstructing a 3-D organ from multiple 2-D image slices. At the molecular level, such 3-D scans ...
The most intense laser in the world is about to get a power upgrade with $2 million from the National Science Foundation.
A flexible, biodegradable optical fiber that can deliver light into the body for medical applications is the latest work of a collaboration between electrical engineers and biomaterials engineers in Penn State's Materials ...
Traditional leg prosthetics enable amputees to maintain mobility and lead more active lives. But these prosthetics depend on soft limb tissue to function and can be painful to wear, resulting in awkward walking motion and ...
A team of Irish scientists has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute, University of Limerick (UL), Ireland, observed ...
Adding or removing water from a stem cell can change the destiny of the cell, researchers have discovered in a new study published yesterday in the Proceedings of the National Academy of Sciences (PNAS).
From 1932 to 1968, hundreds of tonnes of mercury seeped into the clear waters of Minamata Bay, Japan, causing health and environmental problems still felt today. As the first global treaty on mercury finally comes into force, ...
A team of Caltech scientists has uncovered a molecular code that cells use to communicate with each other. This "language" is thought to be common to many types of cellular communication and has implications for designing ...
