An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers or powered drills; they can reach depths of over two miles , and contain ice up to 800,000 years old. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide. Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past. These data can be combined to find the climate model that best fits all the available data. Impur…

The girl who survived rabies is about 15 year old, Jeanna Giese, from Wisconsin in the USA, who survived rabies thanks to an innovative and desperate treatment tried out on her by Dr. Rodney Willougby.

His technique involved putting her into a deep coma allowing her body to begin an antibody response to the disease that let Jeanna gradually regained normal function. Subsequent testing of the same technique did not have such good results.

The School of Doc—a free five-week summer filmmaking camp open to all Durham, North Carolina, public high school students—is an extension of the Full Frame Documentary Film Festival. Participants learn the art and craft of documentary filmmaking from instructors who make their living in the film industry and produce a completed documentary film in partnership with a Durham non-profit organization. The finished films will be presented at the 2016 Full Frame Documentary Film Festival next April, and camp participants will be able to attend the festival free of charge.
