WWF celebrates World Rhino Day
September 22, 2011 11:19 AM - WWF
On the occasion of the second annual World Rhino Day, WWF joins the residents of rhinoceros range countries in calling for an end to rhino poaching, which threatens the survival of rhino species. Officials in South Africa, home to most of the world's rhinos, have responded to the recent poaching crisis by increasing protection for rhinos, conducting more rigorous prosecutions, and imposing stricter sentences on wildlife criminals. This action must be met with a corresponding commitment by countries in Asia where consumer demand for rhino horn is inciting poachers. South Africa has lost at least 284 rhinos in 2011, including 16 or more critically endangered black rhinos. A majority of the poaching incidents have occurred in the world famous Kruger National Park, but privately owned rhinos have also been targeted. Law enforcement officials have made over 165 arrests so far during the year, and some convicted poachers have been sentenced to up to 12 years in prison.
How to run with wolves
September 21, 2011 04:59 PM - Deadly 60 team, BBC Earth
Traveling to the frozen north, Steve and his Deadly 60 team met an animal whose ability to survive in sub-zero temperatures, has made it one of many Norwegian success stories. But how close could they really get to this hardened predator? Well, sorry, you can't. No matter what the Twilight movie says! Wild wolves are extremely hard to get close to, and it's not sensible to try! They are top predators, the largest of the wild dog family living in complex social groups, in remote inhospitable places. They are incredibly hard to see and track in the wild, travelling over huge distances and running at speeds of over 30mph in pursuit of prey. They are ferocious hunters tackling prey many times their own size like elk, bison and musk ox. Wild wolves are not to be messed with.
CO2 Up in the World
September 21, 2011 12:30 PM - Andy Soos, ENN
Global emissions of carbon dioxide (CO2)increased by 45 % between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. Increased energy efficiency, nuclear energy and the growing contribution of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries. This increase took place despite emission reductions in industrialized countries during the same period. Even though different countries show widely variable emission trends, industrialized countries are likely to meet the collective Kyoto target of a 5.2 % reduction of greenhouse gas emissions by 2012 as a group, partly thanks to large emission reductions from economies in transition in the early nineties and more recent reductions due to the 2008-2009 recession. These figures were published today in the report "Long-term trend in global CO2 emissions", prepared by the European Commission's Joint Research Center and PBL Netherlands Environmental Assessment Agency.

Observations from NASA's Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping open the case on one of Earth's greatest mysteries. While scientists are confident a large asteroid crashed into Earth approximately 65 million years ago, leading to the extinction of dinosaurs and some other life forms on our planet, they do not know exactly where the asteroid came from or how it made its way to Earth. A 2007 study using visible-light data from ground-based telescopes first suggested the remnant of a huge asteroid, known as Baptistina, as a possible suspect. The hunt for the killer asteroid goes on.

Yawning is a normal and common human activity. We all yawn but why do we yawn. A study led by Andrew Gallup, a postdoctoral research associate in Princeton University's Department of Ecology and Evolutionary Biology, is the first involving humans to show that yawning frequency varies with the season and that people are less likely to yawn when the heat outdoors exceeds body temperature. Gallup and his co-author Omar Eldakar, a postdoctoral fellow in the University of Arizona's Center for Insect Science, report this month in the journal Frontiers in Evolutionary Neuroscience that this seasonal disparity indicates that yawning could serve as a method for regulating brain temperature.

Milton Berle once said: Laughter is an instant vacation. Now science has added some concrete proof top that statement or so suggests a new study from an international research team, led by Oxford University. The study found that when we laugh properly, as opposed to producing a polite titter, the physical exertion leaves us exhausted and thereby triggers the release of protective endorphins. These endorphins, one of the complex neuropeptide chemicals produced in the brain, manage pain and promote feelings of well being.
Ancient Fossil Aquifers and NASA
September 19, 2011 07:54 AM - Andy Soos, ENN
A NASA-led team has used radar sounding technology developed to explore the subsurface of Mars to create high-resolution maps of freshwater aquifers buried deep beneath an Earth desert, in the first use of airborne sounding radar for aquifer mapping. The research may help scientists better locate and map Earth's desert aquifers, understand current and past hydrological conditions in Earth's deserts and assess how climate change is impacting them. Deserts cover roughly 20 percent of Earth's land surface, including highly populated regions in the Arabian Peninsula, North Africa (Sahara), west and central Asia (Takla Makan) and the southwestern United States (Sonora).
How to find a chimpanzee colony
September 18, 2011 10:57 AM - The Deadly 60 Team, BBC Earth
Waking at dawn and trekking into the forest to meet one of the most intelligent species on the planet is a dream for many people. And for Steve it was exactly that, a dream come true. However with five times the upper body strength of a typical human male, Steve had to tread carefully. Luckily, he had his trusty team and an experienced escort on side to ensure that this close up encounter, was anything but deadly. Chimpanzees are our closest living relatives, probably the most intelligent non-human animal. In East Africa the chimpanzee is found in the wild in Tanzania and Uganda, which is where Steve and the team went in search of them. Chimps are found in rainforests and wet savannas living in communities which can number anywhere from 10 to over 100 individuals sharing a home range which can cover thousands of acres. Chimps spend much of the time moving through the forest in search of fruiting trees, making them difficult to find and follow. Here's how our team tracked them down: ”¢ The right location: They opted to go to Kibale National park, the most accessible of Uganda’s major rainforests. ”¢ The right guides: The deadly crew were escorted by Uganda Wildlife Authority guides, who knew the parks and the chimpanzees.
The Benefits of Maple Syrup
September 16, 2011 04:30 PM - Andy Soos, ENN
Maple syrup is delightful to have on pancakes for example. Now new research conducted at the University of Tokyo suggests that pure maple syrup may promote a healthy liver. The pilot study, conducted by Dr. Keiko Abe of the University of Tokyo's Graduate School of Agricultural and Life Sciences, showed that healthy laboratory rats fed a diet in which some of the carbohydrate was replaced with pure maple syrup from Canada yielded significantly better results in liver function tests than the control groups fed a diet with a syrup mix containing a similar sugar content as maple syrup. The results will be published in the November, 2011 issue of "Bioscience, Biotechnology, and Biochemistry." Although most healthy individuals take liver function for granted, liver health is of great importance because of the hundreds of vital functions it performs that are essential to human life, which include storing energy (glycogen) and regulating blood glucose, the production of certain amino acids (building blocks of protein), filtering harmful substances from the blood.
Climate Warming: Who Thinks What
September 16, 2011 03:32 PM - Andy Soos, ENN
Yale University has created a new poll based report, Politics & Global Warming, which describes how Democrats, Republicans, Independents, and members of the Tea Party respond to the issue of global warming. The results come from a nationally representative survey of 1,010 American adults, aged 18 and older, conducted April 23 through May 12, 2011. The samples were weighted to correspond with US Census Bureau parameters for the United States. The study shows majorities of Democrats (78%), Independents (71%) and Republicans (53%) believe that global warming is happening. By contrast, only 34 percent of Tea Party members believe global warming is happening, while 53 percent say it is not happening. While 62 percent of Democrats say that global warming is caused mostly by human activities, most Tea Party members say it is either naturally caused (50%) or isn’t happening at all (21%).
