Two significant advances in anti-aging therapies in one fell swoop. The first was made by a team of researchers at the University of New South Wales, Australia, coordinated by David Sinclair, who, as told on the pages of Science, has identified the molecular processes that allow cells to repair damage caused to DNA , precisely, from aging and radiation. The second, however, is the work of a group of scientists from the Erasmus University Medical Center in the Netherlands, which have developed - and successfully tested on laboratory mice - a treatment that can lead to suicide older cells. Details of the discovery were published in the journal Cell.
Wrinkles, gray hair and other unpleasant corollaries advancing age may be less inevitable than you think. An experiment in gene therapy is able to "reprogram" the internal genetic clock of mouse cells was able, in six weeks, to visibly rejuvenate the animals, improving cardiovascular health, the strength of the spine and life expectancy.
The anesthetist Jean-Jacques Charbonier, which operates in the region of Toulouse in France, calls himself a "professional who studies the experiences at the border of death" -that the spiritual experiences of patients clinically dead or favored by altered states of consciousness.
This video makes us confident: high-speed cameras immortalize an armor-piercing bullet 7.62 X 63 mm of an M2-fired from a close distance of about 5 meters, at a speed of 3,000 km per hour, against a special panel of the thickness of about 2 and a half centimeters-lose about 65 percent of its mass, thus ending up literally shatter.
