More certainty on uncertainty's quantum mechanical role: Researchers present findings at Frontiers in Optics 2012 that observation need not disturb systems as much as once thought, severing the act of measurement from the Heisenberg Uncertainty Principle
A general method for measuring the precision and disturbance of any system. The system is weakly measured before the measurement apparatus and then strongly measured afterwards.

NASA Mars Curiosity Rover Prepares to Study Martian Soil
NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple.

Research Shows Graphene Nanopores Can Be Controlled: Less Costly Ways of Sequencing DNA Could Open New Possibilities for Disease Prevention
These are transmission electron microscope images of a nanopore in graphene. The original pore on the left grows considerably under the influence of the electron beam. The image on the right is the pore after four minutes at 800 °C. Pores either shrink or grow depending on the temperature and electron beam irradiation.

NASA's Infrared Observatory Measures Expansion of Universe
Astronomers using NASA's Spitzer Space Telescope have greatly improved the cosmic distance ladder used to measure the expansion rate of the universe, as well as its size and age. The cosmic distance ladder, symbolically shown here in this artist's concept, is a series of stars and other objects within galaxies that have known distances.

Comet crystals found in a nearby planetary system
Close-up of olivine crystals seen inside a meteorite found on Earth that originated from a partly melted Solar System asteroid. The yellow olivine crystals are on the order of a few millimetres to centimetres in size and are held together by an alloy of iron and nickel. In contrast, the olivine crystals found in pristine comets, such as in the material measured in the Beta Pictoris system by ESA’s Herschel space observatory, are iron-poor but magnesium-rich.

The Helix Nebula: Bigger in Death than Life
A dying star is throwing a cosmic tantrum in this combined image from NASA's Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent to the California Institute of Technology in Pasadena. In death, the star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core.
