New review associates vitamin D with lower rates of tooth decay
Health scientists have long disputed the role of vitamin D in preventing tooth decay. A new review of existing studies suggests that vitamin D may indeed have a role in tooth health. The review encompassed 24 controlled clinical trials from the 1920s to the 1980s. About 3,000 children in several countries participated. Vitamin D levels in many populations are declining while dental caries in children are increasing. The findings reaffirm the importance of vitamin D for dental health. (2012-11-27)

Space-warping white dwarfs produce gravitational waves
Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to observe. Scientists first detected these ripples in the fabric of space-time indirectly, using radio signals from a pulsar-neutron star binary system. The find, which required exquisitely accurate timing of the radio signals, garnered its discoverers a Nobel Prize. Now a team of astronomers has detected the same effect at optical wavelengths, in light from a pair of eclipsing white dwarf stars. (2012-08-28)

The scent of love: Decomposition and male sex pheromones
Young virgin female hide beetles (Dermestes maculatus) are attracted to cadavers by a combination of cadaver odour and male sex pheromones, finds a new study published in BioMed Central's open access journal Frontiers in Zoology. Neither cadaver scent, nor male sex pheromones alone, caught the fancy of the fussy females. This predilection ensures that there is both a waiting male and food for her larvae, and optimises the chances of reproductive success. (2012-08-13)

Fingering the culprit that polluted the Solar System
For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. The shock wave also injected material from the exploding star into a cloud of dust and gas, and the newly polluted cloud collapsed to form the Sun and its surrounding planets. New work from Carnegie provides the first fully three-dimensional models for how this process could have happened and will be published by the Astrophysical Journal Letters. (2012-08-02)
