Champing at the bits

Article Abstract:

A practical quantum computer can be achieved by 2020 but building a quantum computer is very hard to do because it involves making quantum systems do things that don't come naturally to them. The quantum computer is revolutionary because of its ability to simulate other quantum systems better, because it stores information in 'qubits' such as the electronic state of an atom or ion as opposed to 'bits' or binary digits in conventional or classical computers.

Seeking the solution

Article Abstract:

A huge number of biochemists, planetary scientists, and philosophers are trying to find out whether water, an essential solvent for life, is in some sense 'fine-tuned' for life. One of the ways they have found to explore the relationship between water and life is to modify water's molecular structure or properties until the liquid state itself begins to change.

Back to the future

Article Abstract:

Various features of relativity are tested in laboratories of France and Germany using high-tech versions of the Michelson-Morley experiment. These groups are looking for tiny changes in the time it takes a light or microwave signal to travel through crystalline structures called resonators.
