These findings indicate that Pycnogenol can play an important role in sports by improving blood flow to the muscles and hastening post-e...

'Pinball protons' created by ultraviolet rays and other causes can lead to DNA damage

... wire" in constructing electrical circuits. Such a breakthrough would allow small electronic devices to shrink even further, but how the electrical properties of DNA would work in such a context is not yet understood. The UGA research adds important knowledge about how so-called "deprotonated" DNA base pairs work...

Pathway toward gene silencing described in plants

...ton University in St. Louis have made an important breakthrough in understanding a pathway plant cells take to silence unwanted or extra genes using short bits of RNA. Basically, they have made it possible to see where, and how, the events in the pathway unfold within the cell, and seeing is believing, as the old...

Allergy battle could be won in five years, says scientist

Research links protein to breast-cancer migration

...other organs in the body." News of the scientific breakthrough comes as the University announced Breast Cancer Campaign funding for two other research projects worth nearly £300,000. Dr. Andrew Gilmore, also in the Faculty of Life Sciences, has been awarded a grant of £146,000 to examine in more detail a proces...

Gene discovery opens door to tackling disease

... tests to diagnose breast and prostate cancer. "A breakthrough in the techniques available to diagnose breast and prostate cancer would hopefully allow for earlier detection and, importantly, lead to better survival rates," said Professor Leedman. SLIRP has also been shown to turn down genes involved in energy ...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...including resistance to avian flu. "This research breakthrough came when we turned our attention to primordial germ cells, the precursor cells to sperm and eggs," said Marie-Cecile van de Lavoir, senior scientist at Origen. "These cells ?which we are the first to successfully culture without changing their commi...
