Quoted: PhysOrg news: A midsection between the head and the long tail of sperm contains mitochondria, organelles that generate a cell's power. But sperm have also developed a second energy source to power their long tail. They employ a process known as glycolysis, which breaks down glucose to derive ATP, which cells use for energy.
The pathway for glycolysis requires 10 enzymes. Using special "targeting domains," sperm tether these to a fibrous sheath that runs the length of the tail. In this study, the researchers are trying to re-create this glycolytic pathway by modifying each protein's targeting domain so that they can instead bind to nickel ions on a manufactured chip.

8 Foot Long Bug Fossil Found
wow!Quoted: This was a bug you couldn't swat and definitely couldn't step on. British scientists have stumbled across a fossilized claw, part of an ancient sea scorpion, that is of such large proportion it would make the entire creature the biggest bug ever. How big? Bigger than you, and at 8 feet long as big as some Smart cars.

Giant Bugs Existed!
i knew it in my gut.
hahaQuoted: The discovery of a giant fossilized claw from an ancient sea scorpion indicates that when alive it would have been about two and a half meters long, much taller than the average man. This find, from rocks 390 million years old, suggests that spiders, insects, crabs and similar creatures were much larger in the past than previously thought.
