Magicians have delighted audiences for centuries with magic tricks. What is little known is that they subtly influence decisions. A master like Apollo Robbins can even tell you what he is going to do and you still won't know he is doing it.

Yet there has been little systematic study of the psychological factors that make magic tricks work. A team of Canadian researchers has combined magic and psychology to demonstrate how certain contextual factors can sway the decisions people make, even though they may feel that they are choosing freely.

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years--and, that they erupt almost exclusively during the first six months of each year.

The pulses--apparently tied to short- and long-term changes in earth's orbit, and to sea levels--may help trigger natural climate swings. Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon dioxide might influence climate; but up to now there was no evidence from submarine volcanoes.

To help people with hormone deficiencies, scientists have developed a potential new therapy based on an unlikely model: immune molecules from cows. Their research, published recently in the journal Proceedings of the National Academy of Sciences, shows that human hormones and antibodies can be fused together--mimicking long, stalk-like cow antibodies.

The new study, whose senior authors were Peter Schultz, the Scripps Family Chair Professor at at The Scripps Research Institute (TSRI), and Feng Wang, a principal investigator at the California Institute for Biomedical Research (Calibr), could also provide the foundation for treatments for a range of other diseases.

Don't like the second law of thermodynamics - that heat transfer has limits when trying to do work? Maybe you can just use a different one.

Rather than being an immutable fundamental law, researchers from University College London and the Universities of Gdansk, Singapore, and Delft write in Proceedings of the National Academy of Sciences that they have uncovered additional second laws of thermodynamics which complement the ordinary second law of thermodynamics, they are just not noticeable except on very small scales. 

A cautionary tale on fad diets seems obvious enough; no one should listen to anyone whose sole credentials are putting 'babe' in the name of their website or uses 'holistic' as part of their job description. But even the U.S. and U.K. governments have at times been overrun by epidemiological anecdotes that they nonetheless turn into formal policy.
