The equivalence principle is one of the corner stones of general relativity. Now physicists have used quantum mechanics to show how it fails.
The equivalence principle is one of the more fascinating ideas in modern science. It asserts that gravitational mass and inertial mass are identical. Einstein put it like this: the gravitational force we experience on Earth is identical to the force we would experience were we sitting in a spaceship accelerating at 1g. Newton might have said...
- Scientists at Massachusetts General Hospital are building new livers by using old, unhealthy ones that would normally be discarded. The scientists use a gentle detergent to wash away old cells and debris. The remaining scaffold, which retains its blood-vessel architecture, can then be seeded with healthy liver cells and transplanted into a living animal.
... Unhealthy organs provide a framework for growing replacement ones.
Scientists at Massachusetts General Hospital in Boston have taken the first steps toward building functional, transplantable livers. In a study in rats, published online today by Nature Medicine, the researchers took donor livers, gently stripped them of their cells while leaving other material intact, and then used the remaining structure as a...
Researchers at the Venter Institute explain their groundbreaking techniques.
Last month, researchers at the J. Craig Venter Institute announced that they had made the first synthetic cell by piecing together a genome made from bottled chemicals and transplanting it into a recipient cell. The landmark accomplishment represents a new level of control over the substance of life at the molecular level and...
The company will share parts and production lines between hybrids and conventional vehicles.
Ford is taking a markedly different approach to making hybrids and plug-in hybrids than competitors such as General Motors--and the company hopes this difference will provide it an edge in a potentially volatile market for such vehicles.
