Bone marrow-on-a-chip unveiled (w/video)

The latest organ-on-a-chip from Harvard's Wyss Institute for Biologically Inspired Engineering reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could only be studied intact in living animals.

Functioning of aged brains and muscles in mice made younger

Harvard Stem Cell Institute researchers have shown that a protein they previously demonstrated can make the failing hearts in aging mice appear more like those of young health mice, similarly improves brain and skeletal muscle function in aging mice.

Scientists pack lab into pill for water testing (w/video)

Researchers have reduced the sophisticated chemistry required for testing water safety to a simple pill, by adapting technology found in a dissolving breath strip. Want to know if a well is contaminated? Drop a pill in a vial of water and shake vigorously. If the colour changes, there's the answer.

Biomedical applications of shape-memory polymers: How practically useful are they?

Shape-memory polymers are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to approved products is extremely low. A paper described the general usefulness as well as the limitations of the shape-memory polymers for biomedical applications.
