Cells, dyes and videotape: Online scientific methods journal incorporates multimedia
November 06, 2006Observing the microscopic mysteries of embryos, cells, and chromosomes is feasible with advanced live imaging technologies. In space and time, researchers can follow the fates of embryos, track migrating cells, and watch how molecules signal and interact with each other-all in their native environments. The current issue of CSH Protocols, released online today-http://www.cshprotocols.org-includes biomedical research techniques that incorporate this 'cellular cinematography' and-for the first time-adds multimedia content in the form of movie clips.
Pictures may be worth a thousand words, but they are static: photographs do not truly capture the lively properties of cells and embryos. Images that move in real time permit biologists to more fully observe and compare biological processes. CSH Protocols now has the capability to present movies, which may be used to demonstrate particular techniques and to show examples of experimental results.
Live cell imaging involves tagging specific proteins, organelles, or cellular compartments with fluorescent labels. Movements of the fluorescent markers are then captured and recorded using sophisticated microscopes equipped with cameras or other advanced imaging devices. Because the cells are carefully maintained under optimal growing conditions, scientists can visualize and accurately assess changes in a cell's physiology, morphology, or behavior.
In the current CSH Protocols release, two articles that incorporate imaging technologies are freely available. One describes how to track the movement of RNA molecules in the nuclei of living mammalian cells. The other outlines appropriate equipment for live imaging in Drosophila, the fruit fly used as a model in genetic and developmental studies. Both articles will be useful for many scientists interested in dynamic, microscopic processes, as they are applicable to a variety of species and systems.

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms.
Discovery will assist treatment and research into fatal brain disorder
Research using newly developed Magnetic Resonance Imaging technology could soon allow clinicians to confirm Huntington's disease before symptoms appear in people who have the gene for the fatal brain disease.
New molecular imaging techniques may lead to advances in disease treatment
A promising new technique has been developed that will enable more accurate non-invasive positron emission tomography (PET) imaging of new cells injected into the body, according to researchers at SNM's 55th Annual Meeting.
Memory loss linked to common sleep disorder
For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.
Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of biomedical engineering at Emory University and the Georgia Institute of Technology.
Synergy between biology and physics drives cell-imaging technology
Developing techniques to image the complex biological systems found at the sub-cellular level has traditionally been hampered by divisions between the academic fields of biology and physics. However, a new interdisciplinary zeal has seen a number of exciting advances in super-resolution imaging technologies.
How to make microwaves on a chip to replace X-rays for medical imaging and security
Is microwave radiation the nondestructive imaging technology of the future? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionizing damage caused by X-rays.
Astronomers search for orphan stars using newly upgraded telescope
Using new charge coupled device (CCD) instrumentation, Case Western Reserve University astronomers can now view the night sky wider and deeper than before.
X-rays power discoveries at Chicago's Field Museum
Digital medical imaging and information technology from Carestream Health, Inc., is playing a key role in helping The Field Museum of Chicago discover and analyze secrets hidden within its world-class collections.
MRI: A window to genetic properties of brain tumors
Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery.
