How Spiroplasma might swim.

Spiroplasmas are small helical bacteria without rigid walls. They have a cytoskeleton in the form of a flat ribbon that runs the length of the cell. In an ordinary liquid medium, a cell spins about its long axis, but it does not translate. In a gel-like medium, containing a viscous agent like methylcellulose, it moves rapidly in a direction parallel to its long axis. Here I suggest how a cytosk...

How Might Climate Change Affect Island Culture in the in the Torres Strait?

The Torres Strait Islands are frequently ‘left off the map’ in research on biophysical change in Australia. There are few observational data sets from which modelling work or inundation studies can be performed—even though these communities may be facing imminent threats to their existence. Some of these islands are only a metre or two above local mean sea level; and in the last two years sever...

How to Change the Redox Potential of Guanine?

Due to some important applications of guanine electrode in scientific and technology research such as electro-chemical DNA based biosensors, and a problem of high redox potential of guanine (0.81 V), our research study concentrates on reducing guanine redox potential by substituting Cu, Ag, Au, CH3, C2H5 and Cl on sites of 1, 2 and 9 of guanine. A 5.0% reduction...

Inner Workings: How saving some of the Southeast's oldest trees might help scientists monitor climate change.

In the swampy floodplains of North Carolina’s Black River stand ancient trees with a story to tell. Many of these bald cypress (Taxodium distichum) were well over a millennium old when Columbus discovered the Western Hemisphere. As it turns out, their locale has greatly promoted their longevity: by being relatively inaccessible, the trees have been spared from loggers’ saws. But the inexorable ...
