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 [...]

Whole Genome Duplications Are Potentially An Evolutionary Advantage
A study recently published in Nature suggests that whole genome duplications may have posed an evolutionary advantage in our ancient ancestors. This is a surprising discovery considering the rarity of contemporary whole genome duplications being preserved. These findings may provide insight into new “tactics” organisms use during the course of evolution. Read the original Nature [...]

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 [...]

New Findings Uncover 3 Genetic Links to Alzheimer’s
A new letter in Nature Genetics has shown genetic links of 3 new genes to the onset of Alzheimer’s. The study, featured in the latest edition of the journal, involved 45 different institutions, over 16000 individuals, and is considered the most in-depth and powerful study of its kind. It is expected that these new findings [...]

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 [...]

Monkeys Enjoy Music.. Their OWN Music.
While monkeys prefer silence in the presence of human music, they apparently enjoy the music produced by themselves and their own vocal chords. This could provide significant improvements in the lives of captive animals and offers a unique look at the dynamics of animal physiology and psychology. Read More Read the original publication
