Inbreeding in Panda Population?: Extremely Rare Brown and White Panda Spotted
An extremely rare brown and white panda was recently spotted in the Qinling region of China. Only 7 such examples of this pigmentation have been seen in the past 25 years, suggesting that the low numbers of giant pandas have lead to inbreeding. This suggestion stems from the nature of this particular sort of pigmentation, [...]
Nature’s Exciting Expectations for the New Year
It seems that Nature magazine has high hopes (and don’t we all) for research progress in 2010. Among goals such as glimpsing the origins of the universe and other Earth-like planets, the biological topics expected to make big impacts are:
Stopping/preventing species loss globally
Synthetic genome from pioneers such as Craig Venter
A surge in the number of [...]

Evidence for Environmental and Epigenetic Cause of Autism
A study published a few months ago in the journal NeuroToxicology investigates the non-random variation in prevalence of autism. The study has shown that the highest frequency of autism occurs in areas of the study location (Minnesota) with increased amounts of pollution in the environment, such as mercury and pesticides. The study concludes there is [...]
Transgenic, Green Monkeys Provide Possibility of Primate Model Organisms
This story is a few months old, but I was reading through the Nature homepage and came across their selected Images of the Year slideshow. Many of these images have to do with various space-related or physics themes, but of particular interest to me when browsing through the images was a gorgeous image of fluorescent [...]

More Proof That Smoking Leads to Small-Cell Lung Cancer
In a Nature article published earlier this week, UK and US researchers have provided more proof that smoking has a direct effect on the development of small-cell lung cancer. This study describes 22,910 somatic mutations characterized by massively parallel sequencing technology (including 134 in highly important exon coding regions) in the small-cell lung cancer cell [...]

RNA Interference Technology Will Improve Pharmaceutical Production
RNA interference, or RNAi, has become a novel and useful tool for silencing gene expression in both cells and organisms as well as in developing therapies for diseases. A new study out of Taiwan has recently been published outlining how RNAi technology can be used to vastly increase the quantity and quality of recombinant protein [...]
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 [...]

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 [...]
