DNA gives new perspectives to understand the mysteries of nature
02-13-2007 · EurekAlert!Scientific breakthrough: What caused the extinction of the woolly rhinoceros ten thousand years ago from an area in Europe covering the coasts of the Arctic Ocean in the north to the coasts of the Mediterranean in the south? What caused the extinction of the mammoth while other ice age mammals like the musk ox just barely survived to present day. A new scientific methodological approach to detect genetic material will help researchers to solve the many mysteries of the past.

- Enhanced DNA-repair mechanism can cause breast cancer
10-15-2007 · EurekAlert!
Although defects in the "breast cancer gene," BRCA1, have long been known to increase the risk for breast cancer, exactly how the defects lead to tumor growth has remained a mystery. Now scientists provide insight into how the normal BRCA1 gene suppresses the growth of tumors as well as the nature of the genetic instability that leads to cancer when BRCA1 is defective.

- No matter their size black holes 'feed' in the same way
12-06-2006 · EurekAlert!
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.For many years astronomers have been trying to understand the similarities between stellar-mass sized Galactic black hole systems and the supermassive black holes in active galactic nuclei (AGN).

- Mayo Clinic discovers DNA repair as key to Huntington's disease
04-22-2007 · EurekAlert!
Mayo Clinic researchers, along with collaborators from the National Institutes of Health (NIH) and University of Oslo, Norway, have discovered that a miscue of the body’s genetic repair system may cause Huntington's disease, a fatal condition that affects 30,000 Americans annually by destroying their nervous system. Until now, no one knew how Huntington’s begins, only that it is incurable. The findings appear in the online issue of the journal Nature.

- Scientists find missing link to understand how plants make vitamin C
04-27-2007 · EurekAlert!
Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery. That is until now. A group of Dartmouth and UCLA researchers, who normally work on genes involved in aging and cancer in animals, discovered the last piece of the puzzle, they report in a study published online April 26 in the Journal of Biological Chemistry.

- Shoulder ligament a linchpin in the evolution of flight
12-17-2006 · EurekAlert!
Brown University and Harvard University scientists created a 3-D model of a gliding pigeon, put alligators on a treadmill, and examined rare Chinese fossils to better understand the evolution of flight. They learned how modern birds balance an array of forces, from the pull of muscles to the pull of gravity, at the shoulder joint. They discovered that this "force balance system" changed over time so that a single ligament acts as a linchpin in today's fliers. Results are published online in Nature.
