Bright highlands in equatorial Venus likely ferro-electric. What's up with the high-latitude highlands?

by Paul Wren in Venus Dispatches

OverviewA lot of papers have been written about the highly reflective highlands (in radar) on Venus, with several different hypotheses (e.g. high porosity, metal frost).  Allan Treiman, Elise Harrington, and Virgil Sharpton look specifically at high-latitude highlands in comparison to highlands in the equatorial regions.  Both areas feature high reflectivity, but the reflectance patterns are distinct, as they describe in Venus' radar-bright highlands: Different signatures and mate........

Life amid acidity near a smoldering part of the Arctic

by Rosin Cerate in Rosin Cerate

Way, way up in northwestern Canada (on the lower east side of Cape Bathurst, Northwest Territories), where the mainland meets the Arctic Ocean, a 30 km stretch of seacoast has been smoldering away for hundreds if not thousands of years.The Smoking Hills, named by the explorer John Franklin during one of his early 19th century expeditions to the Canadian Arctic, consist of shale bedrock covered by several meters worth of soil and loose rocks deposited by ancient glaciers and rivers. The land fall........ Read more »

Death by a thousand cuts: how antibacterial clays kill

by Betty Zou in Eat, Read, Science

Researchers at Arizona State University have demonstrated for the first time the mechanism by which antibacterial clays kill bacteria. Iron and alumninum released from the clays damage the outer membrane through oxidation. Iron also enters the cell where it generates hydroxyl radicals to create oxidative stress.... Read more »

A Gift Worth Its Weight In Gold

by Mark Lasbury in As Many Exceptions As Rules

Gold is not considered a dietary micronutrient, and is the one of the most inert metals. But this is not to say it has no role in living systems; in fact, this metal is a veritable gold mine of biology. New research has led to a greater understanding of how gold can down-regulate inflammatory processes and gold complexes are being used in cancer and infectious disease treatments.... Read more »

Missing link in the evolution of complex cells discovered

by Perikis Livas in Chilon

In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes.
