In between red light and blue light: New functionality of molecular light switches
Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth’s atmosphere and perform around one-quarter of the global carbon dioxide assimilation, i.e. they convert carbon dioxide into organic substances. Their light receptors are a crucial factor in this process. Researchers have now discovered that blue and red light sensing photoreceptors control the carbon flow in these algae.

Imaging electric charge propagating along microbial nanowires
Physicists report that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive human-made material.

Crystallizing the DNA nanotechnology dream
For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features -- a design quest just fulfilled by scientists. The team built 32 DNA crystals with precisely-defined depth and an assortment of sophisticated three-dimensional features.

NASA's Terra Satellite sees Tropical Storm Ana over Hawaii
(NASA/Goddard Space Flight Center) Tropical Storm Ana made a slow track west of the Hawaiian islands over the last couple of days, and by Oct. 20 was moving westward away from the main Hawaiian islands and heading toward the northwest Hawaiian islands. NASA's Terra satellite caught Ana on a flyby on Oct. 19 that showed the storm's clouds blanketing the chain of islands.

The quick life and death of Tropical Storm Trudy
(NASA/Goddard Space Flight Center) Tropical Storm Trudy formed on Saturday, Oct. 17 and by Oct.19 the storm made landfall in southern Mexico and weakened to a remnant low pressure area.
