Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip.

  A new microscope system that can take 3-D pictures of an embryonic mouse organ over 24 to 48 hours has shown Duke Medical Center researchers the first glimpse of the formation of blood vessels during development.

A multi-institutional consortium including Duke University has created startlingly crisp 3-D microscopic views of tiny mouse brains — unveiled layer by layer — by extending the capabilities of conventional magnetic resonance imaging.

MIT researchers have created an inexpensive method to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample-a technology that could make possible the development of low-cost clinical bedside diagnostics.

For the first time, researchers at MIT can see every vibration of a cell membrane, using a technique that could one day allow scientists to create three-dimensional images of the inner workings of living cells.

Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel “biosensor” to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses.

For the first time, scientists have been able to watch neurons within the brain of a living animal change in response to experience. Thanks to a new imaging system, researchers at MIT’s Picower Institute for Learning and Memory have gotten an unprecedented look into how genes shape the brain in response to the environment.

Georgia Tech researchers have created a nanoscale probe, the Scanning Mass Spectrometry (SMS) probe, that can capture both the biochemical makeup and topography of complex biological objects in their

A team of investigators at Massachusetts General Hospital has developed a nanoparticle that signals when cells are undergoing apoptosis, the kind of cell death triggered by cancer therapies. The new nanoparticles could finally provide oncologists with a rapid assay that could tell them that a given therapy is working. This groundbreaking work was published in [...]
