Firefly protein lets researchers monitor molecule linked to cancer

...in-protein interactions. Researchers can employ an instrument known as an in-vivo bioluminescence camera to take real-time measurements of light from luciferase in cell cultures and in cells within live animals. To use the firefly protein to monitor IKK, Gross altered cell lines to genetically fuse the lucifer...

NHGRI expands effort to revolutionize sequencing technologies

...ve of this project is to develop a general utility instrument to provide inexpensive sequencing that can also be used for projects to recognize genome variation. The group will design novel nanopores articulated with probes to sequentially, and directly, identify nucleotides in very long fragments of genomic DN...

NCAR analysis shows widespread pollution from 2004 wildfires

...the fires, the research team used a remote sensing instrument known as MOPITT (Measurements of Pollution in the Troposphere) that is operated by NCAR and the University of Toronto and flown on NASA's Terra satellite. The scientists simulated the transport of the pollutants emitted by the fires and the resulting...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...l trap" housed in his Stanford lab. This sensitive instrument allows researchers to observe transcription in real time by trapping individual molecules of DNA and RNAP in minute beams of infrared light. "Our measurements are accurate to one-tenth of a nanometer--the width of a single hydrogen atom," Block expl...

The scanner could be coupled to the surgeon-operated robots that are being increasingly used for performing minimally invasive "laparoscopic" surgeries on the heart or other organs, Smith said. In such operations, surgeons work t...

UCSD study reveals how plants respond to elevated carbon dioxide
