Small spherical objects fill the field in this mosaic combining four images from the Microscopic Imager on NASA's Mars Exploration Rover Opportunity. The view covers an area about 2.4 inches (6 centimeters) across, at an outcrop called "Kirkwood" in the Cape York segment of the western rim of Endeavour Crater. The individual spherules are up to about one-eighth inch (3 millimeters) in diameter.

Two Opposing Worlds Meet: Development or Death (Part I)

The Stockholm World Water Week, Aug. 26-31, sponsored by the Swedish state's International Development Cooperation Agency, and such global cartel companies such as Nestle and PepsiCo, but dominated by the World Wildlife Fund (WWF), the Stockholm Environmental Institute, and similar malthusian propaganda outlets, promised to be orgy in green ideological madness, where African and Asian nations are regarded by Europe and the U.S.A. as an embarrassing burden, and that those nations should be convinced that their misery could only be reduced, but not relieved, by small hand-outs, instead of large-scale industrial and infrastructural development.

UMass Amherst Chemists Develop Nose-like Sensor Array to 'Smell' Cancer Diagnoses

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

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.

Nuclear Power: Extracting Uranium from Seawater

Fueling nuclear reactors with uranium harvested from the ocean could soon become more feasible thanks to a material developed by a team led by the Department of Energy's Oak Ridge National Laboratory (ORNL). The combination of ORNL's high-capacity reusable adsorbents and a Florida company's high-surface-area polyethylene fibers creates a material that can rapidly, selectively, and economically extract valuable and precious dissolved metals from water.

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

Non-Cytotoxic Nanosilver Structures Bring New Hope for Curing Infections

Iranian researchers from Tehran University of Medical Sciences and Stanford University managed to completely eliminate the cytotoxicity of silver nanoparticles, bringing new hopes for curing infections.
