-
TechCloaked eye still sees
Researchers have proposed a model that would allow sensors to send and receive information virtually undetected.
-
HumansIn teeth, more cracks are better than one
Cracks in tooth enamel, called tufts, distribute force and shield a tooth from fracture, researchers report.
-
Materials ScienceDouble-laser approach makes one thin line
Erasing and stenciling could refine tiny printing for sculpting nano-sized devices.
-
PhysicsRadioactive cigarettes
Polonium remains an underappreciated factor in the lung-cancer risk posed by cigarettes.

ChemistryBubbles turn on chemical catalysts
Mechanical force could help chemical compounds spur reactions when the time is right.
-
Materials ScienceViruses could power devices
Viruses — the biological kind — could be used to construct more efficient, environmentally friendly lithium ion batteries
-
PhysicsSpin control for technology
Long-lived helix offers a new way to keep electron spin stable and in sync
-
AstronomyPlanck 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.

ChemistryExxon 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.

SpaceQuantum entanglement can be too much of a good thing
An overdose of the spooky connection can break down quantum computing systems, researchers find.
-
PhysicsNever mind the Pollock ‘fractals’
Scientists strengthen claim that fractal analysis is moot.
-
ChemistryHelping molecules reach meta
Researchers find a simple way to get molecules into the meta position on an aromatic ring, opening fresh possibilities for making new compounds.
