The Wildlife Conservation Society tracked a southern elephant seal for an astonishing 18,000 miles – the equivalent of New York to Sydney and back again.

Jackson, the male southern elephant seal tracked by researchers that traveled an astonishing 18,000 miles.
WCS tracked the male seal from December, 2010, to November, 2011. The animal – nicknamed Jackson – was tagged on the beach in Admiralty Sound in Tierra del Fuego in southern Chile. WCS conservationists fitted Jackson with a small satellite transmitter that recorded his exact location when he surfaced to breathe.
Jackson swam 1,000 miles north, 400 miles west, and 100 miles south from the original tagging location, meandering through fjords and venturing past the continental shelf as he foraged for fish and squid.
During this tracking, the WCS team analyzed the data to better understand elephant seal migratory routes.
Elephant seals are potential indicators of the health of marine ecosystems and may show how climate change influences the distribution of prey species that serve as the basis of Patagonia’s rich marine ecosystem. To protect this vast region, conservationists need to know how wildlife uses it throughout the year.
“Jackson’s travels provide a roadmap of how elephant seals use the Patagonian Coast and its associated seas,” said Caleb McClennen, WCS Director for Global Marine Programs. “This information is vital to improving ocean management in the region, helping establish protected areas in the right places, and ensuring fisheries are managed sustainably without harming vulnerable marine species like the southern elephant seal.”
The information WCS gathers will serve as a foundation for a new model of private-public, terrestrial-marine conservation of the Admiralty Sound, Karukinka Natural Park (a WCS private protected area), and Alberto de Agostini National Park. It will help build a broader vision for bolstering conservation efforts across the Patagonian Sea and coast.
“The Wildlife Conservation Society has a long history of working in the spectacular Patagonia region to establish protected areas and advance conservation of its rich wildlife,” said Julie Kunen, WCS Director of Latin America and Caribbean. “Individual stories like Jackson’s are awe-inspiring, and also inform the science that will ultimately help protect this region.”
WCS reports that Jackson has returned to Admiralty Sound, the site of the original tagging. Each year, elephant seals haul ashore in colonies to molt and find mates. The satellite transmitter is expected to work until early next year, when it will eventually fall off.
WCS has tracked more than 60 southern elephant seals via satellite on the Atlantic side of the Southern Cone since the early 1990s. Jackson represented the first southern elephant seal tagged from the Pacific side of the Southern Cone.
Elephant seals are among the largest pinnipeds in the world, reaching weights of up to 7,500 pounds and lengths of 20 feet.
Since 2004, WCS has owned and managed Karukinka Natural Park, the largest protected area on the main island of Tierra del Fuego. The 728,960-acre park protects the world’s southernmost stands of old growth forests as well as grasslands, rivers, and wetlands. WCS, in partnership with the global investment bank Goldman, Sachs & Co., which donated the lands, has transformed Karukinka into a flagship for wildlife conservation in Patagonia. It is now supported by an advisory council made up of local scientific and business sector representatives who provide recommendations on the park’s development and serves as a model demonstrating how the private sector help advance conservation activities worldwide.
The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes toward nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. Visit: www.wcs.org

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
