Approaching the $100 Genome

 Approaching the $100 Genome
Threading long DNA molecules through nano-sized channels on a specially
fabricated chip could provide a cheaper way to sequence DNA.

It currently costs roughly $60,000 to sequence a human genome, and a handful of research groups are hoping to achieve a $1,000 genome within the next three years. But two companies, Complete Genomics and BioNanomatrix, are collaborating to create a novel approach that would sequence your genome for less than the price of a nice pair of jeans–and the technology could read the complete genome in a single workday.

UK Scientists Make Transistor One Atom Long, 10 Atoms Wide

 

UK Scientists Make Transistor One Atom Long, 10 Atoms Wide
Chunks of this atom-thick material just one nanometer across can function as transistor

A leading contender to replace silicon as the basis for computing has made another step forward.

Transistors one atom thick and ten atoms wide have been made by UK researchers. They were carved from graphene, predicted by some to one day oust silicon as the basis of future computing.

Underwater cell analyzer used to detect harmful marine algae

Through the use of an automated, underwater cell analyzer developed at the Woods Hole Oceanographic Institution (WHOI), researchers and coastal managers were recently able to detect a bloom of harmful marine algae in the Gulf of Mexico and prevent human consumption of tainted shellfish.
