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 [...]

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 [...]

Great Video Depicting Transcription and Translation
This video, part of a PBS production titled DNA: The Secret of Life, depicts the process of transcription and translation, or in other terms, making mRNA from DNA and proteins from mRNA. The video shows the biologically correct molecules, which sets it apart from most other videos depicting the same process and gives it a [...]
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 and [...]

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.
