Alzheimer's Vaccine Shown To Be Safe In Phase II Clinical Trial
A potential vaccine against Alzheimer's has been found safe and capable of producing an immune response, results from a phase II clinical trial have shown.

All normal matter is made of humming particles vibrating at their own frequencies we can’t see. To get them to an almost standstill is incredibly difficult. Scientists just managed it with an object 10 trillion times more massive than the previous record-holder for the heaviest object prepared close to its motional ground state.
