A research team has developed a technique enabling them to perform dynamic proliferation measurements in vivo, independent of surgery or anesthesia. This minimally invasive technique is based...Vitamin D analog found to boost radiation
... issue of the Journal of Clinical Cancer Research, compares tumor growth in mice treated with radiation alone and mice exposed to radiation and EB 1089, a derivative of vitamin D. Final tumor volume in animals irradiated with EB 1089 was approximately 50 percent lower than in the group that received radiatio...UCR scientists modify existing chemical scrubber to environmentally friendly, all-natural filter
...iotrickling filter was about $40,000-60,000, which compares well with the annual savings in operating costs. "If one assumes that 25 to 40 percent of the chemical scrubbers worldwide could be converted to biotrickling filters," said Deshusses, "it would represent a total market of $1-3 billion and would resul...Carnegie Mellon University research story ideas on DNA

... weak and will be more difficult to find. Thompson compares the problem with finding a radio station with a weak signal. It may be possible to detect the signal by increasing the volume, but that would also lead to an increase in static and background noise that would need to be filtered out. Nevertheless, t...Salk Institute and SUGEN scientists map 'human kinome'
