In the quest to repair damaged DNA – a process believed crucial in combating ailments ranging from cancer to aging – antioxidant has been the Holy Grail. But findings published this week in Nature suggest oxidation isnt always the enemy.
Scientists at Michigan State University, along with colleagues in England, have uncloaked a mechanism that uses oxygen to repair DNA – until now an unlikely part of the restorative recipe. Their work is published in the Sept. 12 issue of the British sc
Working with guinea pigs, Johns Hopkins scientists have created what is believed to be the first biologic pacemaker for the heart, paving the way for a genetically engineered alternative to implanted electronic pacemakers. The advance, reported in the Sept. 12 issue of Nature, uses gene therapy to convert a small fraction of guinea pigs heart muscle cells into specialized “pacing” cells.
“We now can envision a day when it will be possible to recreate an individuals pacemaker cel
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency (ESA) hopes to get to the very bottom of it.
Scientists will study space phenomena that do not seem to conform to our perceived understanding of gravity. In this way, they hope to develop a greater comprehension of the Univ
Engineers, computer scientists and graphics technology experts at Purdue University have created the first publicly available simulation that uses scientific principles to study in detail what theoretically happened when the Boeing 757 crashed into the Pentagon last Sept. 11.
Researchers said the simulation could be used as a tool for designing critical buildings – such as hospitals and fire stations – to withstand terrorist attacks.
The simulation merges a realistic-looking visual
Art conservators have been slow to adopt lasers as restoration tools, preferring their trusty scalpels and solvents to untried technologies. But the first systematic study of the long-term effects of lasers on paintings should help ease their doubts: the results show that lasers can be superior restoration tools without sacrificing the safety of priceless works of art.
The findings are reported in the Sept. 15 print edition of Analytical Chemistry, a peer-reviewed journal of the American Ch
For the first time, Stanford researchers have compared genetic patterns with archeological findings to discover that genetics can help predict with a high degree of accuracy the presence of certain artifacts. And they say the strength of this link adds credence to theories that prehistoric people migrated from the Middle East to Europe, taking both their ideas and their way of life with them.
“The recovery of history is really a jigsaw puzzle,” said Peter Underhill, PhD, senior research sci
