A pig's 'mood' can show us how content he is, say researchers at Newcastle's School of Agriculture, Food and Rural Development.

Led by Dr Catherine Douglas, the team has employed a technique to 'ask' pigs if they are feeling optimistic or pessimistic about life as a result of the way in which they live and their results say that pigs are capable of complex emotions which are directly influenced by their living conditions.

The Newcastle team taught the pigs to associate a note on a glockenspiel with a treat (an apple) and a dog training 'clicker' with something unpleasant – rustling a plastic bag.

Almost 30 years ago philosopher James Flynn discovered that IQ scores were increasing in every industrialized country around the globe. But before we pat ourselves on back, Bronson and Merryman warn us that we may be in the midst of a Creativity Crisis. Although IQ scores continue to climb, creativity scores, at least as measured on the Torrance Test of Creativity are dropping through the floor. 

After reviewing the scores of 300,000 children using the Torrance Test of Creativity, Kyung-Hee Kim of the College of William and Mary saw a steep decline in scores from kindergarteners to 6th graders.

What does the ionosphere sound like?  Well, our Project Calliope sonification will map the ionosphere's properties to a musical range.  What you'll hear is the volume and changes of activity within it.

In some ways, sound is the best method for getting a 'big picture' of an item.  Think of a large body of water.  With your eyes close, you can tell the gentle lapping of a lake from the burble of a brook, the flow of a river, or the periodic crashing waves of an ocean.

Werner Heisenberg's 'Uncertainty Principle'(1927) is a fundamental concept in quantum physics, basically saying you can be increasingly accurate in position or momentum (mass X velocity), but not both(1).  

This can be an important feature rather than a defect in something like quantum cryptography, where information is transmitted in the form of quantum states such as the polarization of particles of light.

A group of scientists from LMU and the ETH in Zurich say they have shown that position and momentum can be predicted more precisely than Heisenberg's Uncertainty Principle states - if the recipient makes use of a quantum memory that employs ions or atoms.

Optics normally treats the behaviour of packages of light waves (photons). However, when passing through appropriately shaped fields, particles may behave similar as photons. A beam of electrons that is not too dense will under such conditions behave similar to light beams that pass comparable lenses. In a dense beam the electrons will influence each others path via their own Coulomb field.
