The number of animals used for experiments in Switzerland dropped by 13.1 per cent, or 99,547 animals, in 2011 compared with the previous year, the Federal Veterinary Office said on Thursday. Via Jeff Makana

Expedition 30 astronaut Don Pettit uses knitting needles and water droplets to demonstrate physics in space through 'Science off the Sphere.' This is part of the first video in a series for a partnership between NASA and the American Physical Society to share unique videos from the International Space Station with students, educators and science fans from around the world.

Pagan gods traditionally required human sacrifices – preferably of children – and a West Country academy school appears to be leading the way. To give pupils a lesson in "sustainability" they'll never forget, headmaster Rob Benzie of Ansford Academy in Castle Cary, Somerset, ordered a "No Power Day ... as an experiment to see if we can lower our carbon footprint". It took place in December as temperatures plummeted to 1°C, and pupils students were permitted to cheat death by wearing as many jumpers as they could muster. All survived. Predictably, reactionary parents branded it as "barbaric" – ignoring the vital "awareness raising" potential of the experiment. An innovative game in Australia even advised children when they should pop off to help save the Earth Goddess.

A bizarre freckly-pinkish creature with no hair but a white tail and mohawk-style plume of hair terrified locals in Xinxiang, located in Henan province, China, so much that many were convinced that it was botched "genetic experiment" that escaped from a nearby science facility.

In their experiment the German team, led by Markus Oberthaler at the Kirchhoff Institute for Physics, have created a special form of quantum entanglement, called mode entanglement, which rather than involving two particles involves two gases, each containing on average 40 particles. In each gas they measured a property called quadrature and found that the values of quadrature in the gases correlate to a greater extent than classical (that is non-quantum) physics can explain. What is novel about their work is the method they used for accessing these quadratures. "It took so long to get access to [the quadratures] since they are 'encoded' in noise — which is tricky to observe since there are usually many annoying noise sources which are just classical," says Oberthaler. "Thus the experimental challenge is to get the environment under control such that technical noise is not hiding the interesting 'quantum noise'." The result has been published in Nature.

A new thought experiment makes it clearer than ever that photons aren’t simply particles or waves.
