Incredible Jungle games - Follow the hunter, New from BBC Earth
June 17, 2011 08:42 AM - Willow Murton, Assistant Producer, Oceans and Jungles team, BBC Earth
"Is it all going to be like this?" Human Planet's Assistant Producer Willow Murton takes us into the thick of the rainforest and shares what it's really like to be confronted by deadly poisoned darts, a broken down boat and fortune in disguise. There are places that you imagine you may return to and people you may meet again and then there are farewells to people and places you assume you will hold as a treasured memories. For me Aurelio village was one of those places; so remote, so distant, one of only two communities where the Matis of Brazil live. Set in the vast indigenous Vale do Javari reserve, it takes several days' boat ride to reach the village, as well as many months of painstaking preparation. I had first come here to make the series "Tribe" and couldn't believe my luck when I was asked to make a return trip for "Human Planet"— a rare privilege. There is good reason to return to this remote corner of the Amazon for Human Planet's Jungles episode. The Matis are true masters of the rainforest. Pete, our endurance fit cameraman, and I are reminded of this on our first filming day. An hour into the hunt we’d come to film, we are up to our knees, even thighs at times in swamp mud, soaked through by the unrelenting rain and all eyes on deadly poisoned darts being fired over our heads! Pete turns to me and asks if it's all going to be like this?
Short Term Air Emissions and Their Effect on Global Warming
June 16, 2011 03:37 PM - Andy Soos, ENN
Fast action on certain pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 3.6 degrees F. Protecting the near-term climate is central to significantly cutting the risk of amplified global climate change linked with rapid and extensive loss of Arctic ice on both the land and at sea, said assessment authors including Veerabhadran Ramanathan, a climate and atmospheric scientist at Scripps Institution of Oceanography, UC San Diego.
Returning to the Caveman Diet
June 16, 2011 09:12 AM - David A Gabel, ENN
In today's age of highly processed food, packaged and shaped to look like animals, filled with ingredients we have never heard of, it is tempting to return to a diet from a much simpler time. A new fad that is catching on, known as the Paleolithic or "paleo" diet, aims to return people to a more "natural" way of eating. Before agriculture, people would eat lean meats, fruits, and vegetables, and they would avoid grains and processed foods. Is this what is really best for human consumption? According to a new book, the so-called caveman diet was abandoned for a reason, and the belief that it is superior is pure hokum.

Nature's fury reached new extremes in the U.S. during the spring of 2011, as a punishing flooding and rainfall brought the greatest flood in recorded history to the Lower Mississippi River, an astonishingly deadly tornado season, the worst drought in Texas history, and the worst fire season in recorded history. There's never been a spring this extreme for combined wet and dry extremes in the U.S. since record keeping began over a century ago as shown by statistics released last week by the National Climatic Data Center. One other results is the Gulf of Mexico’s hypoxic zone is predicted to be larger than average this year, due to extreme flooding of the Mississippi River this spring, according to an annual forecast by a team of NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University and the University of Michigan. The forecast is based on Mississippi River nutrient inputs compiled annually by the U.S. Geological Survey. Scientists are predicting the area could measure between 8,500 and 9,421 square miles. The largest hypoxic zone measured to date occurred in 2002 and encompassed more than 8,400 square miles.
New from BBC Earth: The circus comes to town
June 14, 2011 12:06 PM - Mark Flowers, Producer/Director Rivers/Urban team, BBC Earth
Traveling to the farthest corners of the world, it is not just the remarkable environments that can prove a little hard to capture. When Rivers Producer/Director Mark Flowers met the children from the North-East Indian root tree villages, he hadn't bargained on having to make himself the center of attention. But sometimes it's the little extra's that make an experience unforgettable. The most heart-stealing and downright soul- enhancing benefit of working on a Human Planet shoot is the children we encounter while we are filming. It's unbelievably refreshing to step outside of a regulated, fast-paced and impersonal modern, urban society and meet people who live in a more open, communal and for me personally, a far more "Human" way. The children we met during our trip to film living root bridges in one of the most remote areas of North-East India were fantastic — cheeky, smart and funny. To the young people who live in isolated hill villages in the rainforests of Meghalaya, the arrival of a gangly bunch of giant, pale-skinned strangers, brandishing weird black boxes, screens and cables, was the most surprising thing to happen in a long while. The circus had come to town! Within minutes of us stepping out of the cars, there were bright eyes at the windows and small hands waving from the homes we passed. High pitched "hellos" echoed all around while tiny toddlers stood dumb struck for a few seconds in doorways and then exploded into howls. Dogs barked and sulky, caged cuckoos crooned from dark corners.
The Wetness of Water
June 14, 2011 08:13 AM - Andy Soos, ENN
Water is amazing. It occupies about 2/3rds of the Earth's surface. It is the basis of life in many ways. It interacts with the atmosphere as a major cleanser of sorts. So how does it do it? Some water molecules split the difference between gas and liquid, a study in Nature shows. Air and water meet over most of the earth’s surface, but exactly where one ends and the other begins turns out to be a surprisingly subtle question. A new study in Nature narrows the boundary to just one quarter of water molecules in the uppermost layer — those that happen to have one hydrogen atom in water and the other vibrating freely above.
Measuring Ruminant Emissions Through Biomarkers Found in Stool
June 13, 2011 10:08 AM - David A Gabel, ENN
Livestock is a significant contributor to greenhouse gases. The ruminant digestive system creates ample amounts of methane which is released into the atmosphere. It is difficult to measure the amount of methane produced by cows because unlike emission stacks, ruminant exhaust cannot be controlled or monitored. However, researchers from the University of Bristol and the Teagasc Animal and Grassland Research Centre in Ireland have made the connection between methane production and a certain chemical found in the stool of cows, sheep, and other animals. This link may be used to more accurately estimate methane emissions by animals and assess their contribution to global warming.
The Waste of Heat
June 13, 2011 07:08 AM - Andy Soos, ENN
No system is 100% effective. There is always some energy wasted. One of the more common examples is the automobile engine which gets quite hot. Some of the waste is recovered by heating the car for example. With the completion of a successful prototype, engineers at Oregon State University have made a major step toward addressing one of the leading problems in energy use around the world today — the waste of half or more of the energy produced by cars, factories and power plants. New technology is being developed at the university to capture and use the low-to-medium grade waste heat that’s now going out the exhaust pipe of millions of automobiles, diesel generators, or being wasted by factories and electrical utilities. The new systems now being perfected at the university should be able to use much of that waste heat either in cooling or the production of electricity.
Natural Gas Green Role
June 10, 2011 01:34 PM - Andy Soos, ENN
Some people believe that all energy related problems can be resolved with renewable sources such as solar power or wind power. Maybe in the long term future this will be so. However, in the short term what is the best option for those fuels (energy sources) that we have? MIT (Massachusetts Institute of Technology) has issued a report that states that natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation. That’s the conclusion reached by a comprehensive study of the future of natural gas conducted by an MIT study group comprised of 30 MIT faculty members, researchers, and graduate students. The findings, summarized in an 83-page report, were presented to lawmakers and senior administration officials this week in Washington. The two-year study, managed by the MIT Energy Initiative (MITEI), examined the scale of U.S. natural gas reserves and the potential of this fuel to reduce greenhouse-gas emissions. Based on the work of the multidisciplinary team, with advice from a board of 16 leaders from industry, government and environmental groups, the report examines the future of natural gas through 2050 from the perspectives of technology, economics, politics, national security and the environment.
Court Rules France Not Doing Enough to Protect Its Hamsters
June 10, 2011 10:20 AM - David A Gabel, ENN
When the subject of hamsters comes up, most people would think about the cute furry pets that run on wheels and roll around in clear plastic balls. But in Europe, there is an endemic species of wild hamsters. Much like mice, they live a very fragile existence, always on the lookout for predators. Now, that predator has come in the form of the French, who are driving them toward extinction.
