In a pre-clinical non-small-cell lung cancer metastasis model in mice developed by Frank Jirik and colleagues at the University of Calgary, Rotello's team at UMass Amherst use a sensor array system of gold nanoparticles and proteins to "smell" different cancer types in much the same way our noses identify and remember different odors.

The Pencil Nebula is pictured in a new image from ESO’s La Silla Observatory in Chile. This peculiar cloud of glowing gas is part of a huge ring of wreckage left over after a supernova explosion that took place about 11 000 years ago.

The material, HiCap (from high-capacity), outperforms today's adsorbents, which perform surface retention of solid or gas molecules, atoms or ions.

The obtained nanostructure is nontoxic to human cells, in contrast to the conventional silver nanoparticles, and possesses a spectacularly enhanced antibacterial effect.

Hubble sees a supernova explosion called SN 2004dg on the edge of NGC 5806, a spiral galaxy in the constellation Virgo. It lies around 80 million light years from Earth.

Real-time imaging of a rodent brain shows that nanoparticles coated with polyethylene-glycol (PEG) (green) penetrate farther within the brain than particles without the PEG coating (red)

Particularly tested for carbon based substrates such as carbon nanocabon tubes, the proposed method has enabled the synthesis of platinum-cobalt nanoparticles featuring lower dimensions, narrower size distributions and higher stabilities compared to the conventional methods.

In 1604, a new star appeared in the night sky that was much brighter than Jupiter and dimmed over several weeks. This event was witnessed by sky watchers including the famous astronomer Johannes Kepler. Centuries later, the debris from this exploded star is known as the Kepler supernova remnant.

Observations by NASA's Mars Reconnaissance Orbiter have detected carbon-dioxide snow clouds on Mars and evidence of carbon-dioxide snow falling to the surface.

A hypothetical planet is depicted here moving through the habitable zone and then further out into a long, cold winter.
