Pushing through nanopores: Genetic sequencing with MXene

It took 13 years and one billion dollars to sequence the human genome, an enormous scientific undertaking that launched a new era of medicine. With today's advances in sequencing technology, that same task would have only ...

Rapid DNA Detection Quickly Diagnoses Infections

(PhysOrg.com) -- A new portable device can detect bacteria and help prevent the spread of infectious diseases. This new tool takes from 15 minutes to 2 hours to diagnose a patient for infectious diseases and can be used in ...

Detecting Our Martian Cousins

The iguanas of the Galapagos Islands have evolved many unique characteristics due to their isolation from mainland iguanas. Because they can't swim long distances, biologists believe that the first Galapagos iguanas arrived ...

Replication of enzyme-nucleotide chimeras

DNA polymerases are the "Xerox machines" that replicate our DNA. They must work with great precision to keep errors from creeping into our genes. In spite of this precision, they still accept building blocks that have been ...

A rapid, easy-to-use DNA amplification method at 37 Celcius

Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid detection, their method ...
