Do looks matter in the work place? There are a lot more unattractive people running departments and entire companies than there are pretty ones - but a new paper by academics says just the opposite. Pretty people have an easier time on the job.

The paper by Timothy Judge, professor of management at the University of Notre Dame, and Brent Scott from Michigan State University, is the first to link attractiveness to cruelty in the workplace. 

Despite the horrors of the Maoist regime, the Communist Party dictatorship in the People's Republic of China continues to exist and retain control, even though tens of millions of people suffered from persecution or were executed for political reasons while he lived. 

Even less likely, the perpetrators and victims have managed to continue living together long after the death of Mao Zedong and the beginning of the reform era in 1978.

Why do we value gold? It's not strong, it's not pretty, it's rare but in the 21st century, given enough energy we can turn lead into gold, the way alchemists once only dreamed about.

It's not just rare on Earth, it's rare in the universe, even though the universe has a fantastic amount of energy, it is a perpetual Philosopher's Stone. Yet even in the infinite universe creating gold is not trivial. Unlike elements such as carbon or iron, gold cannot be created within a star. Instead, it must be born in a more cataclysmic event, like one that was witnessed last month: a short gamma-ray burst.

Neutrinos are the second most abundant particles in the Universe, after photons, but when it comes to being elusive they can compete with anything. That's due to their having extremely weak interactions with all other particles, which leads to them being called  'ghost particles’.

Neutrinos are invisible but could carry as much mass as all other known forms of matter, traveling almost at the speed of light over fantastic distances. Their tiny masses have  important consequences for the structures in the Universe and they are the driving element in the explosion of Supernovae.

A group at the Bristol Robotics Laboratory have developed a novel way of charging mobile phones - using urine as the power source to generate electricity.

Lead author Dr. Ioannis Ieropoulos from the University of the West of England is an expert at harnessing power from unusual sources using microbial fuel cells and says, “We are very excited as this is a world first, no-one has harnessed power from urine to do this so it's an exciting discovery. Using the ultimate waste product as a source of power to produce electricity is about as eco as it gets.”

Basically, the microbial fuel cells contain bacteria that produce electricity from pee. Bet you never thought of that, Muad'Dib.

The Earth has a violent history: About 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the sun, gathering in rocky clumps to form asteroids. These asteroids, gaining momentum, whirled around a fledgling solar system, repeatedly smashing into each other to create larger bodies of rubble — the largest of which eventually cooled to form the planets.

Countless hypotheses, simulations and geologic observations support such a scenario, but there remains one lingering mystery: If the Earth arose from the collision of asteroids, its composition should resemble that of meteoroids, the small particles that break off from asteroids.
