In teeth, more cracks are better than one
Cracks in tooth enamel, called tufts, distribute force and shield a tooth from fracture, researchers report.

Planck by Planck
The launch of the European Space Agency’s Planck mission, set for late April or early May, will put into orbit a new tool —the microwave equivalent of polarized sunglasses — that may offer a view of the dawn of time.

Exxon Valdez oil lingers, as does its toxicity
Even 20 years after a major oil spill, barely degraded pockets of the oil persist within some intertidal beaches, research shows.

Quantum entanglement can be too much of a good thing
An overdose of the spooky connection can break down quantum computing systems, researchers find.

Never mind the Pollock ‘fractals’
Scientists strengthen claim that fractal analysis is moot.
