Rock fins up to about 1 foot (30 centimeters) tall dominate this scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity.

A three-dimensional image of an etched gallium-arsenide semiconductor, taken during etching with a new microscopy technique that monitors the etching process on the nanometer scale. The height difference between the orange and purple regions is approximately 250 nanometers.

The finely honed tip of the atomic force microscope (AFM) allows one to pick up single biomolecules and deposit them elsewhere with nanometer accuracy. The technique is referred to as Single-Molecule Cut & Paste (SMC&P), and was developed by the research group led by LMU physicist Professor Hermann Gaub.

Now, researchers have reported, for the first time, the fabrication of CNT-fiber-based stretchable conductors by a simple prestraining-then-buckling approach. Upon release of the prestrain, the CNT fibers are readily kinked in-plane because of their high flexibility.

In newly published research, Kunio Kimura and colleagues report that the morphology of poly(p-oxybenzoyl) precipitates formed by the co-polymerisation of 4-acetoxybenzoic acid with trifunctional co-monomers based on 3,5-diacetoxybenzoic acid (DABA) is significantly influenced by the structure of the co-monomer and the solvent. As part of their research the authors varied the co-monomer, solvent, co-polymer ratio, temperature of polymerisation, and concentration.

This new image from ESO’s La Silla Observatory shows part of a stellar nursery nicknamed the Seagull Nebula. This cloud of gas, formally called Sharpless 2-292, seems to form the head of the seagull and glows brightly due to the energetic radiation from a very hot young star lurking at its heart.

This image combines photographs taken by the Mars Hand Lens Imager (MAHLI) at three different distances from the first Martian rock that NASA's Curiosity rover touched with its arm.

Janssen K is a roughly 12-kilometer-diameter crater on the floor of the large Janssen Crater. Several debris flows can be seen running down the walls of the crater.
