Visualize the Unbelievably Small Scale of the Cell (and other Biological Structures)
Single cells are small. Really, REALLY small. When you read that a suspended cell is approximately 10-15 microns in diameter it all seems fine and well; you’ll write it down or take note of it, then move along. However, if you stop to think about how small 10-15 microns is, it begins to baffle your [...]

First Synthetic Cellulosome In Yeast Created
ScienceDaily (Nov. 2, 2009) — A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found.

New Fluorescence Microscopy Techniques Directly Image Drug Delivery
X Sunney Wei and others at Harvard University recently demonstrated a new technique for stimulated emission microscopy that allows high resolution imaging of generally non-fluorescent chromophores (such as drugs). This imaging technique relies on pumped laser sources and new techniques for obtaining the fluorescent emission streams. Use of this sort of microscopy could lead to [...]

BioImage of the Week #2
The BioImage for this week comes to us from GPMatthews’ personal website. The site contains a large collection of fascinating images and articles, particularly on the pages that contain images of diatoms. These unicellular organisms are like biology’s snowflakes and often offer some of the most interesting and complex patterns that can be visualized under [...]

BioImage of the Week #1
The image above is featured from Cornell University’s Life Sciences Core Laboratories Center. It is a gorgeous image of a bovine pulmonary artery endothelial cells taken with laser scanning confocal microscopy techniques. The cell is stained with a three dye system showing:
Tubulin: BODIPY FL-labelled tubulin antibody
Actin: Texas Red-X phalloidin
Nucleus/Chromosomes: Texas Red-X phalloidin
This gorgeous image illustrates [...]

Neurons May Be Up To 50% More Efficient Than Previously Thought
A recent publication in Nature has suggested that rather than being only 30% efficient, neurons, the workhorse cells of our brains, may be acting at up to 70-80% efficiency. This has heavy implications, considering that neurons consume approximately 20% of our body’s consumed energy. The question must now be asked: what exactly are those little [...]

Cancer Motility Mechanisms Observed
A new study out of Harvard Medical suggests that cancer cells have an intrinsic ability to mechanistically move through channels such as blood vessels as they make their way through the body and leave tumors. The study, published in Integrative Biology, uses a variety of microchannels and chemicals to treat the cells to a different [...]
