Tasmanian scientists have taken a leap forward in a battle to save a rare and endangered plant. The plant has been reproducing itself for over 43 000 years, it's probably the oldest living clone in the world.

In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, scientists at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than earlier strains, cutting the time to reach electricity-producing concentrations on the electrode.

"A Natural History of Rape: Biological Bases of Sexual Coercion", argues that rape is an adaptation, a trait encoded by genes that confers an advantage on anyone who possesses them. Back in the late Pleistocene epoch 100,000 years ago men who carried rape genes had a reproductive and evolutionary edge over men who did not: they sired children not only with willing mates, but also with unwilling ones.

Mating between the rare California tiger salamander and the introduced barred tiger salamander has created a monster—at least for animals that dwell in the ponds of California's Salinas River Valley.

Experiment after experiment confirms that a diet on the brink of starvation expands lifespan in mice and many other species. But the molecular mechanism that links nutrition and survival is still poorly understood. Now, researchers have identified a pivotal role for two enzymes that work together to determine the health benefits of diet restriction.

I read a fantastic article in Nature magazine that summarizes not only the current state of novel H1N1 (aka Swine Flu) understanding, but also a compares H1N1 against other flu strains. In particular, it discusses in-depth how the pathogenic components — i.e., the stuff that kills you — compare against each other.

A self-assembling molecule synthesized in a laboratory may resemble the earliest form of information-carrying biological material, a transitional stage between lifeless chemicals and the complex genetic architectures of life.
