Science & the Public: Large Hadron Collider suffers carb attack
Efforts to get the Large Hadron Collider up and running just encountered a temporary snag, according to yesterday's online edition of The Times of London. A crusty chunk of bread “paralysed a high voltage installation that should have been powering the cooling unit.”
Science & the Public: Nanoparticles' indirect threat to DNA
Tiny metal nanoparticles can damage DNA, essentially by triggering toxic gossip.
Quantum computers could tackle enormous linear equations
New work suggests that the envisioned systems would be powerful enough to quickly process even trillions of variables.
