The reefs at Funafuti have suffered damage, with 80 per cent of the coral becoming bleached as a consequence of the increase in ocean temperatures and ocean acidification. The coral bleaching, which includes staghorn corals, is attributed to the increase in water temperature that occurred during the El Ninos that occurred from 19982000 and from 20002001. A reef restoration project has investigated reef restoration techniques; and researchers from Japan have investigated rebuilding the coral reefs through the introduction of foraminifera. The project of the Japan International Cooperation Agency is designed to increase the resilience of the Tuvalu coast against sea level rise through ecosystem rehabilitation and regeneration and through support for sand production.
What percentage of the Tuvalu coral has become bleached?
80 per cent

In July 2007, the National Archives announced it would make its collection of Universal Newsreels from 1929 to 1967 available for purchase through CreateSpace, an Amazon.com subsidiary. During the announcement, Weinstein noted that the agreement would "... reap major benefits for the public-at-large and for the National Archives." Adding, "While the public can come to our College Park, MD research room to view films and even copy them at no charge, this new program will make our holdings much more accessible to millions of people who cannot travel to the Washington, DC area." The agreement also calls for CreateSpace partnership to provide the National Archives with digital reference and preservation copies of the films as part of NARA's preservation program.
What company did the National Archives partner with make it's Universal Newsreels available online?

In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
What does a black object do to any of the light that hits it?
it absorbs all the light
