Quantum Bug: Qubit might spontaneously decay in seconds
Article Abstract:
Physicists should overcome a fundamental obstacle before quantum computers can become a practical reality, causing decoherence, that is, the loss of the very quantum properties, which computers would rely on. A device based on superconducting quantum bits (qubits) predicts that new source of decoherence would degrade the quibits after just a few seconds.

Chaos in the crater
Article Abstract:
Vredefort is the oldest and largest impact remnant on the planet, created about two billion years ago with a 10-kilometer-wide asteroid slammed into the earth. Intense, random magnetism in the Vredefort Crater occurs due to a strong and chaotic magnetic field generated by currents flowing in the ionized gases produced at the height of the collision.
