Social networks doomed to fail?
Quote
Social networking technology is a great tool. But, like most powerful tools, it can be misused. If you value your relationships, remember that the true strength of most relationships is determined by the content of the relationship and the effort invested by both parties, rather than the mechanism that established the relationship in the first place.
Women are turn-offs in bed.

The results of the study are striking. As the women were stimulated, activity rose in one sensory part of the brain, called the primary somatosensory cortex, but fell in the amygdala and hippocampus, areas involved in alertness and anxiety. During orgasm, activity fell in many more areas of the brain, including the prefrontal cortex, compared with the resting state, Holstege told a meeting of the European Society for Human Reproduction and Development in Copenhagen on Monday.
Martian microbes may threaten Earth.

So astronauts could inadvertently bring the life back to Earth, with potentially dangerous consequences. "The possibility of transporting a replicating life form to Earth, where it is found to have a negative effect on some aspect of Earth's ecosystem" would present the greatest biological risk, the team wrote.
Growing sperm and eggs. Gattica, here we come.

Work by several groups has shown that a tiny proportion of human embryonic stem cells (ESCs) spontaneously develop into primordial germ cells when allowed to differentiate in a dish. In this latest study, Behrouz Aflatoonian and colleagues at the University of Sheffield, produced primordial germ cells which began to express the proteins characteristic of sperm cells, while others resembled eggs.

The submarine-launched rocket, carrying the solar sail is targeted for liftoff on June 21 at 3:46 p.m. EDT. The Volna rocket being tapped to toss Cosmos 1 into a roughly 500 mile (800 kilometer) circular, near polar orbit is a converted ballistic missile of the type once armed and aimed at the United States. Cosmos 1’s flight is viewed as a stepping stone in developing future solar sail technologies. Solar sailing has been a long sought technology that could lead to future interstellar flight.
