Dinosaur DNA? New Patent Covers Degraded DNA recovery

...used DNA samples to become degraded. "We hope this gives criminal investigators another tool to re-open cold cases or revisit crime scenes, stringing together strands of detached DNA into a genetic trail that could solve a crime or exonerate the falsely accused," says Dr. Ensley. This patent is part of a ...

Results of the study appear the week of March 28 in the early online edition of the Proceedings of the National Academy of Sciences. Most primary brain tum...

Scientists collaborate to assess health of global environment

... "This is really important because the global view gives averages, and global averages may be misleading," he said, noting that different ecosystems face different issues--overfishing in the Caribbean, for example, versus groundwater usage in Chile's Atacama Desert or wood fuel harvesting in Zambia. Overa...

BRCA1 causes ovarian cancer through indirect, biochemical route

...The well-known breast cancer gene, BRCA1, not only gives carriers of its mutated form a four in five chance of developing breast cancer, it also confers a 40 percent risk of developing ovarian cancer by the age of 70. How that risk is imparted, however, had been harder to pin down. "We've known for a long...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...ed that the Streptomyces bacterium -- the bug that gives us the antibiotic streptomycin -- also produces a natural compound called migrastatin, which appears to inhibit cell migration. Natural migrastatin's effect is relatively weak, but Dr. Huang suspected the molecule might be manipulated into something...

The algorithm was applied to three different data sets and the results obtained were compared to work done by others using the same data sets. This study presents an entropy-based iterative algorithm for se...

Nano-Probes Allow an Inside Look at Cell Nuclei
