Summary Restoring sight with stem cells; underground climate clocks; surpassing the Hubble Telescope; the chameleon's ballistic tongue; The Surfing Scientist demonstrates; and how long is a year on Neptune?CORNEAL STEM CELLSThe cornea, the transparent outer layer of the eye, can lose clarity if the stem cells in the outer layer aren't doing their job properly, causing a reduction in or even loss of vision. Maryanne Demasi witnesses brilliant new surgery that transplants stem cells from a patient's healthy eye to rejuvenate the damaged cornea of the other eye.FOLDING OBSERVATORYThe Hubble Space Telescope has been called one of the most productive scientific instruments ever made, capturing images of the distant cosmos in amazing detail. But now, NASA is building a new space telescope far more powerful than the Hubble. Graham Phillips goes to Los Angeles for a sneak preview.CAVES AND CLIMATEThe history of Earth's climate has been well informed by the gases trapped in ice and marine sediments. But, a more ancient complementary record is being exploited. Looking at carbon and oxygen isotopes within stalagmites and stalactites, geochronologists can establish exactly when dramatic changes occurred across the world. Paul Willis drills into the story in the Wombeyan Caves of NSW.BALLISTIC TONGUESChameleons have a deadly weapon hidden in their mouths a spring loaded tongue. But like all reptiles, its performance suffers in the cold. Researchers from the University of South Florida have filmed the hot and cold tongue action of the chameleon and found that it has a clever strategy to catch its breakfast when it's nippy.SCIENCE DEMONSTRATIONSNothing conveys the excitement and principles of science quite like a good practical demonstration. Ruben Meerman teams up with Graham Phillips to demonstrate Newton's 1st Law of Motion and the perfect reversibility of Laminar Flow. NEPTUNE'S SOLAR CIRCUITNeptune has just completed its first orbit of the Sun since it was first observed by astronomers in 1846. It's a planet with one year equivalent to 164.79 Earth years - that must be worth a birthday bash!
