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 [...]

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 [...]

Mitochondrial gene replacement in primate offspring and embryonic stem cells
Researchers at the Oregon National Primate Research Center have successfully replaced damaged and diseased mitochondria (and, likewise, their mtDNA) with healthy mitochondria with no apparent side effects in Macaca mulatta. This has strong implications for future treatment and prevention of mitochondrial DNA associated diseases. Original Publication in Nature : Mitochondrial gene replacement in primate offspring [...]

Baylor researchers find fat cell blocker
A newly discovered molecule dubbed “fatostatin” has been implicated in stopping the pathway that is responsible for fat cell production, as well as cholesterol retention and insulin resistance. Studies in mice show positive results for controlling the negative effects of weight gain. Read more
