But among the rest of us with normal color vision, can we ever be sure we’re seeing exactly the same thing?

In this video from Vsauce, Michael investigates this very question in addition to other...

Lab Grown Kidneys Have Been Successfully Transplanted Into Animals

While scientists around the world continue to debate the use of the CRISPR/Cas9 system, the tool capable of precisely editing DNA on the genomic level, British scientists working at the Francis Crick Institute in London announced today that they have applied for permission from the United Kingdom's fertility regulator (the UK Human Fertilization & Embryology Authority) to use this technique on viable human embryos.

Mitochondrial function changes as we age

A new study finds that age-related onset of type 2 diabetes and impaired glucose tolerance may be due to the lowered ability of muscle mitochondria to switch from metabolizing fatty acids to metabolizing glucose in healthy elderly people compared to young people. The study was reported in the Proceedings of the National Academy of Sciences. Americans over the age of 65 are more likely to develop type 2 diabetes or glucose intolerance. The reasons for this are largely unknown, but studies have shown that muscle insulin resistance, increased intramyocellular lipid content (IMCL,...
