Mankind must abandon earth or face extinction: Hawking
Mankind’s only chance of long-term survival lies in colonising space, as humans drain Earth of resources and face a terrifying array of new threats, warned British scientist Stephen Hawking on Monday.

Wax, soap clean up obstacles to better batteries
A little wax and soap can help build electrodes for cheaper lithium ion batteries, according to a study in August 11 issue of Nano Letters. The one-step method will allow battery developers to explore lower-priced alternatives to the lithium ion-metal oxide batteries currently on the market.

Dark-matter search plunges physicists to new depths
The universe consists of a large amount of invisible matter – dark matter. We do not know what it is, but we know that it is there and that without dark matter there would be no galaxies, and hence stars, planets and life as we know it. The universe is filled with large structures that are dominated by dark matter and in these dark matter spheres or ‘halos’ the light emitting particles form stars and gas clumps. Recent studies show that these dark matter halos have so-called attractors, which preserve their shape. The results are published in Astrophysical Journal Letter.

Hold the Calculators: Let’s Talk About Math!
Many children, when learning to read, are encouraged by their teachers to retell all they remember about a story in order to build their comprehension skills. But can similar comprehension strategies be applied to mathematics? Researchers at North Carolina State University say that when teachers work with kids to talk through math problems, kids do a better job of absorbing and understanding the content.

Foreclosure reduces home’s eventual┬ásale price by 27 percent on average
Foreclosure reduces the eventual sale price of a home by an average 27 percent, compared to the prices paid for similar properties nearby. Those nearby homes, in turn, could see their own prices depressed by 1 percent, if they happen to be within 250 feet of the foreclosed property.
