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...

Researchers find missing genes of ancient organism

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

... cell's nuclear trafficking mechanism, a ploy that gives the virus an unhindered ride inside the nucleus. Chen and Gerion obtained a portion of this protein and attached it to the quantum dot. The result is a hybrid quantum dot, part biological molecule and part nano-sized semiconductor, that is small enou...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

Changes to the ECM and cytoskeleton are critical to migration of a cancer cell from one site in the body to another. The researchers could alter the Alu I sensitivity of a cell's chromatin by exposing the cell to...
