But good science is always open-minded, and the history of science is one of surprises and overturnings. Science is nothing but careful thinking, and careful thinking encourages an appreciation of the complexity of the world. The complexity encourages us to maintain several possibilities at once. In a single lifetime, we may have no way to remove the ambiguities from these possibilities.

Scientists isolate, hold, photograph individual Rubidium 85 atom

(PhysOrg.com) — In a major physics breakthrough, University of Otago scientists have developed a technique to consistently isolate and capture a fast-moving neutral atom – and have also seen and photographed this atom for the first time.

Random numbers created out of nothing

Now Christian Gabriel’s team at the Max Planck Institute for the Science of Light in Erlangen, Germany, has built a prototype that draws on a vacuum’s random quantum fluctuations. These impart random noise to laser beams in the device, which converts it into numbers.

Sound can leap across a vacuum after all

Now a theoretical analysis by Mika Prunnila and Johanna Meltaus, both of the VTT Technical Research Centre of Finland in Espoo, suggests that sound may be able to leap across a vacuum separating two objects made of piezoelectric crystals. These crystals generate an electric field when squeezed or stretched by sound waves or other forces, and deform in an electric field.

Study shows real partners are no match for ideal mate

Our ideal image of the perfect partner differs greatly from our real-life partner, according to new research from the University of Sheffield and the University of Montpellier in France. The research found that our actual partners are of a different height, weight and body mass index than those we would ideally choose.

Unlocking the secret of beauty: Scientists discover the complexities of attractive female bodies

Scientists in Australia and Hong Kong have conducted a comprehensive study to discover how different body measurements correspond with ratings of female attractiveness. The study, published in the Journal of Evolutionary Biology, found that across cultural divides young, tall and long armed women were considered the most attractive.
