Twitter, the newest social networking sensation, can generate sales leads for your business faster than other social network, even with a slashed budget, says David White, Founder and Chief Executive of Weboptimiser and he says he can tell you how your company can benefit from it when he presents his webinars in July.   He says Twitter is generating up to half the hits on his company’s website.

Nothing makes biologists happier than psychologists declaring things a product of evolution.   Now it turns out even social constructs like 'taking turns' have gotten some benefit from evolutions' 'invisible hand'.

How so?   It spans across species so it must be evolution, say University of Leicester psychologists professor Andrew Colman and Dr Lindsay Browning, who carried out the simulations due to appear in the September issue of Evolutionary Ecology Research which they say helps explain the evolution of cooperative turn-taking.

If you've read your history and wondered about when the next Ice Age is coming, you can thank global warming it hasn't happened.    But it could be worse.   Earth's 4.5 billion years have seen several instances where temperatures changed dramatically, like in life ending ways, along with asteroids bombarding the planet and any number of species going extinct without a single activist to hunger strike for them.

But one of the biggest moments in Earth's lifetime is a positive one - the Cambrian explosion roughly 540 million years ago when complex, multi-cellular life burst out all over the planet.   Scientists can pinpoint this pivotal period as leading to life as we know it today but no one is sure what caused the Cambrian explosion of life.

The news that Newcastle University researchers have used embryonic stem cells to create human sperm under laboratory conditions has led to a lot of questions; like, who will television commercials make fun of if all men are gone?

In the technique developed at Newcastle, stem cells with XY chromosomes (male) were developed into germline stem cells which were then prompted to complete meiosis - cell division with halving of the chromosome set. These were shown to produce fully mature sperm called In Vitro Derived sperm (IVD sperm). 

Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 — so more than heat wave deaths in French elderly people in 2003 while French young people protested much fewer deaths in the American invasion of Iraq but far less than the nearly 15,000,000 who die annually from cancer.

And it's almost one-third higher than the previously claimed 60,000 deaths but, like many things in pollution-related deaths, accurate numbers are hard to pin down.   You take some sample data and you extrapolate.

If nanotechnology has a dream future, it is self-assembling and self-organizing systems - something nature has been producing for millions of years.

A team of scientists has examined how thousands of bacterial membrane proteins are able to assemble into clusters that direct cell movement to select chemicals in their environment and they say their results provide valuable insight into how complex periodic patterns in biological systems can be generated and repaired.
