Discernment of rare alleles in circulating free DNA (cfDNA) may be a useful method for detecting the presence of new or recurring cancer long before it becomes symptomatic and, perhaps, when it is more treatable. Unfortunately the false-positive rate of current methods reduce specificity to an unacceptable level at allele frequencies of less than ~0.5%.

Is the software that runs life the result of accumulated copying errors? Or does it require a programmer? This episode of Science Uprising examines how Microsoft founder Bill Gates, geneticist and entrepreneur Craig Venter, and even evolutionary biologist Richard Dawkins all acknowledge that DNA is like software. But how was that software created?WATCH NOW
Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.
