NASA has released a number of stunning colour photographs of the planet Pluto. The pictures have been compiled from four images from the New Horizons’ Long Range Reconnaissance Imager mixed with color data from the Ralph instrument. The new pictures indicate that Pluto is covered by masses of flowing ice.

So when Salomon Amar, a periodontal specialist at Boston University, began exploring links between oral bacteria and heart disease in animal studies in the late 1990s, reactions were lukewarm. “Many cardiologists thought we were a bit crazy,” he says. Skepticism still abounds, but the same molecular tools that have dramatically changed understanding of the gut microbiome are now allowing scientists to track and examine bacteria in the mouth. Advocates of a connection between the artery disease atherosclerosis and microbes are hoping to find convincing proof of their suspicions, while exploring links between ailing gums and other conditions, including cancer, arthritis, diabetes and even Alzheimer’s disease.

German architect Andre Broessels has developed a spherical glass solar power collector that tracks the sun and can collect much more power than the flat screen solar collectors. Still in its development he has patents pending in 5 jurisdictions and hopes to market it in the near future. The indiegogo campaign has been successful and he is now testing.

In January, researchers Mike Brown and Konstantin Batygin proposed that a possible ninth planet was orbiting on the outer edge of the solar system. They created a mathematical model that showed a distant, Neptune-sized planet might be influencing the orbital path of six smaller objects out in the Kuiper Belt.
