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.

Salk scientists, Saket Navlakha and Charles Stevens have a paper that shows that the way fruit flies identify smells that are most similar to ones they’ve encountered previously could improve computer search algorithms.WATCH NOW
