A Big Bird Flapping
June 23, 2011 03:49 PM - Andy Soos, ENN
How does a baby bird learn to fly? One anecdote is to push them out of the nest and hope they do not hit the ground. It is also similar o how a human baby learns to walk. The muscles have to grow strong enough to do the job. It can take months for their partially developed wings and flight muscles to become airworthy, and by then the youngsters are almost fully grown. However, long before their maiden flight, chicks probably put their developing wings to use, flapping as they run up steep branches. Brandon Jackson from the University of Montana, USA, explains that Ken Dial and his son first noticed this strange behavior when filming chukar chicks negotiating obstacles: instead of flying over, the birds ran up over the object flapping their wings. When Dial discussed this behavior with local ranchers and hunters, some described adult chukars flapping to run up cliffs. So why do adult birds flap and run up steep objects when they are perfectly capable of flying? Jackson, Dial and their colleague Bret Tobalske wondered whether pigeons might use 'flap running' to save energy, so they measured the amount of power generated by the flight muscles of flap running and flying birds and found that flap running birds use less than 10% of the energy of birds flying at the same angle.
Jail Time for Clean Air Act Violator
June 23, 2011 09:32 AM - David A Gabel, ENN
The Clean Air Act is an environmental law but it is a law nonetheless. Breaking it will subject the violator to punishment by the courts. Yesterday, a West Des Moines, Iowa resident was sentenced by a US District Judge to 41 months of prison, followed by two years of supervised release, 300 hours of community service, a $12,500 fine, and an addition $200 fine for each victim of his crime. The charge against him was conspiracy to violate Clean Air Act asbestos work practice standards during the renovation over 10-story building in Des Moines.

We all complain about the weather. It is a great topic of conversation. Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather is part of what life is about. However, everything has its price. New research indicates that routine weather events such as rain and cooler-than-average days can add up to an annual economic impact of as much as $485 billion in the United States based on 2011 data. Rain, snow, and hot or cold temperatures can all have economic impacts. The study, led by the National Center for Atmospheric Research (NCAR), found that finance, manufacturing, agriculture, and every other sector of the economy is sensitive to changes in the weather. The impacts can be felt in every state.

The summer solstice occurs exactly when the Earth's and the moon's[clarification needed] axial tilt is most inclined towards the sun, at its maximum of 23° 26'. The summer solstice occurs in June in the Northern Hemisphere north of the Tropic of Cancer (23°26'N) and in December in the Southern Hemisphere south of the Tropic of Capricorn (23°26'S. The Sun reaches its highest position in the sky on the day of the summer solstice. For the northern hemisphere this year solstice will occur June 21 at 5.16 PM UTC. This is also the longest day. For millenia it has been celebrated as a key event of the seasons.
Study: Liquefied Coal may become an Economically Viable Fuel Option
June 21, 2011 10:08 AM - David A Gabel, ENN
Coal is a combustible sedimentary rock that has become the world's most used energy source. Because it is so abundant and therefore cheap, much research has been done to see what other kinds of uses it can have other than direct burning for electricity production. The liquefaction of coal is one concept that is being given new life due to higher petroleum prices. Currently it is cost-prohibitive and environmentally unfriendly. But according to a new study from the Massachusetts Institute of Technology (MIT), as early as 2015 and without a solid climate policy, coal-to-liquid (CTL) fuel may be economically viable in the US and China.
Global Warming Lawsuit
June 20, 2011 02:45 PM - Andy Soos, ENN
The Supreme Court on Monday rejected a global warming lawsuit against five big power companies, its most important environmental ruling since 2007 and a victory for the utilities. The utilities — American Electric Power Co Inc, Southern Co, Xcel Energy Inc, and Duke Energy Corp, along with TVA — account for about 10 percent of US carbon dioxide emissions. The justices unanimously overturned a ruling by a U.S. appeals court that the public nuisance lawsuit now involving six states (California, Connecticut, Iowa, New York, Rhode Island and Vermont) can proceed in an effort to force the coal-burning plants to cut emissions of gases that contribute to climate change. In a defeat for environmentalists, the Supreme Court agreed with the companies that regulating greenhouse gases should be left to the Environmental Protection Agency (EPA) under the clean air laws.
Secrets of Lyme Disease Revealed
June 20, 2011 09:30 AM - David A Gabel, ENN
Lyme disease is an infectious disease caused by several bacteria of the genus Borrelia. It is the most common tick-borne disease in the world, transmitted from deer ticks throughout the northern hemisphere. The disease was named after the town of Lyme, Connecticut where a number of cases were identified in 1975. A new study has now revealed that the deadly bacteria appears to hide within the lymph nodes. This finding may explain why some people suffer from repeat infections of Lyme disease.

An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute's research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel, scientists report. Understanding seismic background signals leads to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years. A seiche is a standing wave in an enclosed or partially enclosed body of water. Seiches and seiche-related phenomena have been observed on lakes, reservoirs, swimming pools, bays, harbors and seas. The key requirement for formation of a seiche is that the body of water be at least partially bounded, allowing the formation of the standing wave.
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.
