"This distinction goes to a future autonomous version of the 700-tons Caterpillar mining truck. In this article, Discovery News reports that Caterpillar engineers and computer scientists from Carnegie Mellon University have teamed up to develop this autonomous truck. Japan-based Komatsu has already delivered autonomous mining trucks to its customers, but these are smaller than the Caterpillar ones. Both companies are transforming their trucks into 'robots' for three reasons. Improvements in safety, efficiency and productivity will reduce costs and increase availability."

"European astronomers have for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet. Designated HD 189733b, also known as a 'hot Jupiter,' orbits a star slightly cooler and less massive than the Sun about 60 light-years from Earth. According to a Zurich news release, 'Polarization technique focuses limelight,' the researchers used 'techniques similar to how Polaroid sunglasses filter away reflected sunlight to reduce glare. They also directly traced the orbit of the planet, a feat of visualization not possible using indirect methods.' The team thinks that their findings are opening new opportunities for exploring physical conditions on exoplanets."

"When we think about alternative sources of energy, we often forget the potential of geothermal energy resources. In fact, it has been estimated that accessible geothermal energy in the U.S. represents 90 quadrillion kilowatt-hours or 3,000 times the country's total annual energy consumption. So far, it has been difficult and expensive to locate good sources of geothermal energy. But now, two U.S. researchers have found a new method which doesn't require drilling. They are using the ratio of helium isotopes in surface waters to point to the best sources of geothermal energy."
