Rice University researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods.
Faster, portable microbial analysis in the field
Until recently, it took hours – sometimes days – to analyze biological samples after they were frozen in the field and brought back to the laboratory. But now there is a faster, cheaper and smaller way ...
New device successfully captures metastasis-associated circulating tumor cell clusters
The latest version of a microfluidic device for capturing rare circulating tumor cells (CTCs) is the first designed specifically to capture clusters of two or more cells, rather than single cells. The new ...
Researchers can trace dust samples using fungal DNA

Scientists identify mineral that destroys organic compounds, with implications for Mars Curiosity mission
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, with implications for Mars research.
Researchers find bubonic plague fragments on NY subway
It is universally acknowledged that the New York subway is grubby. What may come as a shock is that it contains DNA fragments linked to anthrax and bubonic plague.
Soils could keep contaminants in wastewater from reaching groundwater, streams
With endocrine-disrupting compounds affecting fish populations in rivers as close as Pennsylvania's Susquehanna and as far away as Israel's Jordan, a new research study shows that soils can filter out and ...
Contamination of impacted meteorites can happen quickly
A team of scientists has published the results of an investigative survey into the Sutter's Mill meteorite that landed in California in 2012.
Tropical trees may not be the carbon sink planet scientists have been hoping for
