Healing Bone Fractures with 3D Printing and Stem Cells: Watch This Space

Dr John A. Szivek, a biomedical engineer and professor of orthopedic surgery, has received a five-year, $2 million grant from the U.S. Department of Defense to launch a study to determine how to heal bone fractures using a combination of 3D printing and adult stem cells.

Improving Nature’s Own Ability To Kill Dangerous Bacteria


The ramifications of bacteria's ability to become resistant to antibiotics can be seen in hospitals, public places, our food supply, and our water. Now, researchers have demonstrated how we could improve upon the ability of nature's exquisitely selective collection of antimicrobial enzymes to attack bacteria in a way that's much less likely to cause bacterial resistance.


Decoding the Genetic Mechanisms of Aging


The discovery in the 1990s that a mutation in a single gene of an experimental worm could double its lifespan set off a stampede of research on the molecular biology of aging and triggered hopes that drug therapies or other interventions could be developed to extend healthy human lifespan. But as is often the case in science, the genetic regulation of aging is more complicated than it first appeared.


APOE-Activated Microglia Could Form Link Between Tau Tangles and Neurodegeneration, Suggests Mouse Study


Tangles of a protein called tau can be found in the brains of people with Alzheimer's disease. A new study has found that brain immune cells called microglia form the crucial link between protein clumping and brain damage. The research shows that eliminating such cells cuts tau-linked brain damage in mice - showing a way forward for studies in humans.
