Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of tissue or drop of blood. But they don't tell you where specific genetic ...

Although it is an important technology for studying genomes, DNA sequencing was initially accomplished in 1977 by Frederick Sanger. Since its conception, the technology has developed rapidly. Alvaro G ...

Roche has put forward a new approach to genetic analysis, which it describes as sequencing-by-expansion—a proprietary method that pulls apart the DNA molecule and amplifies the signal of each ...

Students take samples of water and the microscopic creatures within at the Alviso Marina County Park. (Image by Erika Cardema) At the Alviso Marina County Park, reddish-brown water laps at the edge of ...

Harvard scientists have unveiled a new technique called expansion in situ genome sequencing (ExIGS) that combines existing in situ genome sequencing (IGS) with expansion microscopy (ExM). The ...

Nanopore sensors are tiny devices used to detect and analyze individual molecules by measuring ionic changes as the molecules pass through nanometer-scale openings. These sensors are classified into ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...
