The National Geographic Society aims to be an international leader for global conservation and environmental sustainability. The only uncontacted tribe in South America outside the Amazon is having its forest rapidly and illegally bulldozed by ranchers who want their land to graze cattle for beef, Survival, a British-based charity that advocates for indigenous people, said this week. Survival has been publicizing the deforestation by advertising it on a major Paraguayan radio station, Radio Nanduti. The ranchers are operating on the tribe’s land in Paraguay despite having their licence suspended by the Environment Ministry in August for previous illegal clearance, Survival said in its statement. Some of the Totobiegosode have already been contacted and have relatives among those who remain uncontacted, Survival said. Said Survival director, Stephen Corry, “The Totobiegosode are the most vulnerable uncontacted tribe in the world.

Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi.
With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa.
In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave.

The hits keep coming: After nailing a "crazy" landing, Curiosity sends images of its new home, while an orbiter snaps the rover itself. In its first color picture from the surface of Mars, released Tuesday, NASA's Curiosity rover shows the rim of its new home, 15,000-foot-deep (4,600-meter-deep) Gale Crater, shortly after landing on Monday. High above Curiosity, NASA's Mars Reconnaissance Orbiter (MRO) caught this picture of the rover dangling from its parachute about one minute before landing on Monday. Looking something like scorch marks, the dark areas shown in an orbiter's picture were actually created by the planned crash of the "sky crane" lander, which exposed darker, lower Martian soil Monday. Amateur cartographers report on the shifting battle lines to create maps that are among the most accurate and up-to-date reports on the hostilities.

As ice melts and aquifers are drained, Earth's distribution of mass is changinga€”and with it the position of the planet's spin axis.
NASA's Opportunity rover captured the incredible picture by chance after clambering up a steep ridge. From snow-capped peak to smoldering crater, see how the major eruption 30 years ago today changed the face of the famous volcano.
Douglas firs, Pacific silver firs, and mountain hemlock seemed to block the sky over old-growth forests around Spirit Lake, as seen in a picture taken in 1979 (left) by the U.S. Another photograph taken from Johnston's Ridge in September 1980 shows the largely barren landscape surrounding Mount St.
It took more than 200,000 photographsa€”and a whole lot of lucka€”to capture an incredible scene from a carcass dump in Grand Teton National Park.
Egyptologist and National Geographic explorer Sarah Parcak uses high-flying cameras to reveal lost cities and save ancient treasures from looters.
Egyptologist Sarah Parcak, winner of the $1 million TED Prize, envisions dramatic discoveries fueled by technology. Sarah Parcak credits the Tooth Fairy for sparking her first dreams of working as an archeologist in Egypt. Nowadays the pioneering Egyptologist often looks toward the sky to locate treasures buried underground. Parcak analyzed infrared and laser-generated images captured from 700 miles above the Earth to detect the buried remains of buildings, which affect the overlying soils, vegetation, and water. The burgeoning field of space archaeology is allowing researchers to map and model everything from buried Mayan ruins in Central America to hidden structures along Central Asiaa€™s Silk Road.
With each new batch of images, it becomes increasingly clear that archaeologists have vastly underestimated the size and scale of past human settlements. Satellite images have also revealed the accelerating scale of looting at sites around the worlda€”particularly in Egypt, where civil order broke down during the revolution in 2011. Satellite photos made in 2010 (top) and 2013 (bottom) document an upsurge in looting at the ancient site of South Dashur in Egypt. Recently she led a pilot project to identify, track, and monitor looting at two archaeological sites south of Cairo. Parcak says shea€™d eventually like to replicate the project at other sites around the world, allowing the archaeological community and other concerned people to report looting incidents through crowdsourcing sites. While putting the latest aerospace technology to work in archeologya€™s race against looters, urban sprawl, and changing climate, Parcak looks forward to using emerging data to answer some of the fielda€™s oldest and biggest questions: Why did the Pyramid Age end, and why did ancient Egypt collapse?
The $1 million TED Prizea€”awarded annually to a leader with a fresh, bold vision for sparking global changea€”is intended to fund a world-changing a€?dream project,a€? which Parcak will reveal early next year at the 2016 TED Conference. In the meantime, the technology Parcak uses is improving a€?at an astonishing rate,a€? she says. Of course any discoveries made by these high-flying cameras will still need to be confirmed by archeologists working on the ground with trowels and sifting screens. The tsunami was triggered by an underwater 9.0-magnitude earthquake between the Indonesian island of Sumatra and the Indian Andaman Islands.
The wave devastated coastal communities, wiping villages off the map and carrying boats onto unfamiliar, dry territory. Officials estimated that the tsunami forced more than one million Sri Lankans from their homes. Dichato is on the Pacific coast approximately 43 miles (70 kilometers) south of the epicenter of the earthquake.

To learn firsthand what's going on in and around this marine treasure of global importance, the National Geographic Society sent its top scientists and officials to the region in January 2016. The photo was shot with the Mars Hand Lens Imager (MAHLI) on the end of Curiosity's robotic arm. The radar enabled Monday's flawless landing by providing crucial altitude and velocity data.
While hovering above Mars earlier, the rocket-powered lander gingerly lowered Curiosity to the surface.When Curiosity was safely on the ground and the sky-crane tethers released, the rocket used its remaining fuel to zip toward its doom at an angle, to avoid crashing atop the rover. Helens still appear as gray ash fields a few years after the eruption, as seen in a 1983 Landsat picture.The barren landscape provided new opportunities for some new tree species.
Helens was showing signs of healing, as seen from a Landsat satellite."When the blast first occurred, the region looked fairly lifeless, but it's become a very rich environment over the last 30 years," Washington State's Swanson said. Helens sitting in contrast to Mount Hood's snowy peak.Magma rising into the volcano from Earth's interior triggered the earthquakes, which ultimately caused Mount St.
Helens's crater.Malone, the retired director of the University of Washington's Pacific Northwest Seismic Network, called the 1980 Mount St. Parcak, winner of the 2016 TED Prize, which was announced today, has pioneered the use of satellite imaging systems to map, quantify, and protect humanitya€™s past. Because ancient Egyptians built most structures out of mud bricks, which are much denser than the soil that surrounds them, Parcak and her team could see the shapes of houses, temples, and tombs. Using images captured by satellites, archaeologists can more precisely target their excavations and surveys. According to Parcak, images made from space can be used to track the destruction of archeological sites and could be part of a coordinated effort to reverse the tide of looting and illegal antiquities trafficking.
Later this month, she and her team will get their first look at images from a new satellite camera so powerful it can depict objects less than one foot in size. The notion that there will always be a place for old-fashioned digging and discovery is one that Parcak finds comforting. The earthquake that caused the Chile tsunami was powerful enough to move the entire city of Concepcion ten feet to the west and shorten the Earth's rotation.
They toured the desert islands off the southeastern coast of the Baja Peninsula and they listened to presentations by more than a dozen experts, including several whose Baja California research is funded by the Society. But because the arm hasn't yet been fully activated and the rover isn't yet mobile, the camera for now can point only in the direction dictated by the landing position."We can't control the orientation of the rover on landing," Peter Theisinger of NASA's Jet Propulsion Laboratory (JPL) said at a pre-landing press conference. MRO's HiRISE camera team needed months to make sure the orbiter was pointed in precisely the right direction at the right time. The lander itself is too small to be seen, but the longest streaks are about 400 feet (120 meters) long.In addition to the parachute, upper heat shield, and sky-crane vehicle, NASA scientists believe that they've spotted both the rover and its lower heat shield in images from the orbiter. These electronic eyes in the sky are helping archaeologists discover an invisible world of lost tombs, temples, and pyramidsa€”even an entire Egyptian city buried for 3,000 years. If it's pointed at the rim, we'll get a great picture of the rim."Actually, the idea of a great picture may be a bit optimistic at the moment, regardless of orientation. Dust kicked up by the Mars landing has settled on the transparent shield meant to protect the camera during descent.
In about a week, though, the cap will be removed, NASA scientists say, allowing sharper images in the future.
