Science can make you a better dancer - or at least improve your chances of not looking stupid to the opposite sex, say a group of evolutionary psychologists who used 3D motion-capture technology to create uniform avatar figures and identified the key movement areas of the male dancer’s body that influence female perceptions of whether their dance skills are “good” or “bad”.
Apparently it all comes down to neck, trunk, left shoulder and wrist, the variability of movement size of the neck, trunk and left wrist, and the speed of movement of the right knee.
Sounds simple, right? Read on.
We want to know some things in science are absolute yet we accept that a lot is relative. The speed of light is absolute and so the same with respect to any observer in empty space but sound is relative, like when a train whistle goes from high to low as it passes the observer. A longstanding quest in physics has been to determine whether chaos, in which tiny events lead to very large changes in the time evolution of a system, such as the universe, is absolute or relative in systems governed by general relativity, where the time itself is relative.
Like right after the Big Bang.
A 19th century nursery rhyme called "What Are Little Boys Made Of?" and generally attributed to Robert Southey goes
"What are little boys made of? What are little boys made of? Snips and snails and puppy-dogs' tails, that's what little boys are made of.
What are little girls made of? What are little girls made of? Sugar and spice and everything nice,
that's what little girls are made of."
But these days in Australia both genders, even only four weeks old, are made of sugar. And salt and high-fat foods, despite health authorities recommending exclusive breastfeeding to six months of age.
Psychotropic medications - psychostimulants like Ritalin, antidepressants like Prozac and antipsychotics like Haldol - during pregnancy increase the probability of birth defects, according to a University of Copenhagen study.
In Denmark, psychotropic medications were associated with 429 adverse drug reactions in Danish children between 1998 and 2007 - more than half of the 429 cases were serious and several involved birth defects, such as birth deformities and severe withdrawal syndromes.
While proponents of organic farming insist it can meet population projections and is better for wildlife, scientists at the Universities of Leeds and York say instead a balanced approach is superior. At least for butterflies.
Their study found that organic farms have more butterflies than conventional farms but that a conventional farm plus an area specifically managed for wildlife could support more butterflies and produce the same amount of food from the same area of land. Drawback: the wildlife area would have to be similar in quality to a nature reserve rather than similar to an uncultivated field margin, which boosts costs even more.
The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, shows a team from the Jet Propulsion Laboratory, Delft University of Technology (TU Delft, The Netherlands) and SRON Netherlands Institute for Space Research in Nature Geoscience.
The melting of the ice caps has been charted since 2002 using the measurements produced by the two GRACE satellites. From space they detect small changes in the Earth's gravitational field and these changes are related to the exact distribution of mass on Earth, including ice and water. When ice melts and lands in the sea, this therefore has an effect on the gravitational field.
