New look at relativity: Electrons can't exceed the speed of light -- thanks to light itself, says biologist
When resolving why electrons can never beat the speed limit set by light, it might be best to forget about time. Thanks to insight from studying movement inside a biological cell, it seems that light itself -- not the relativity ...

How not to blow up a molecule
High-charge-state ions in a molecule cause strong Coulomb forces, repulsive forces that try to blow its atoms apart. But the research team's crucial finding was that a way to produce only lower charge states ...

Study reveals a 'missing link' in immune response to disease (w/ Video)
The immune system's T cells have the unique responsibilities of being both jury and executioner. They examine other cells for signs of disease, including cancers or infections, and, if such evidence is found, ...
