Foster’s is teaming up with scientists at the University of Queensland to convert beer wastewater into energy. They will be building a “fuel cell” powered by bacteria. The bacteria will consume the beer wastewater, which is ripe with all sorts of good stuff: sugar, starch, and alcohol.
The cell will convert the chemical energy into electrical energy. Don’t get too excited, they are talking about a cell that can generate 2 kW of power, enough to only power one home.
Why don’t they take it one step farther? Might as well use the beer waste water they are putting into the Foster can.

According to the WHO, over 150 million people worldwide now have diabetes. The surge is in Type II diabetes, which afflicts adults over 30. Diabetes is one of three major new diseases that hardly existed 100 years ago: diabetes, heart disease, and cancer.
In the May 3rd issue of Human Reproduction, Queen’s University researcher’s show a link between diabetes and low sperm quality. There was no significant difference in sperm concentration, appearance, or mobility. There was a small reduction in sperm volume. But the most significant affect was a higher DNA fragmentation, 53% versus 32% in non-diabetics. DNA fragmentation could affect the ability to fertilize an egg and even lead to abnormalities in an offspring.
Sperm DNA does not have the ability to repair itself unlike other DNA in the body. The damage is permanent.
The authors of the study admit more work is to be done, including analyzing birth defects in children with diabetic fathers.
Healthy sperm look like points of light. The DNA fragmented sperm have tails on the end.
