Brazil's Growth Offers Wealth and Worry in The Northeast
March 13, 2012 09:57 AM - Leon Kaye, Triple Pundit

Two years ago I predicted this would be the Brazilian Decade, and so far Brazil's stunning success has proven me correct. It is not just about the large international events like the World Cup and Olympics that are on the calendar in 2014 and 2016. Brazil has become a creditor nation; once a net food importer, it now feeds much of the world; and recently it surpassed the United Kingdom to become the world's sixth largest economy. For decades much of the growth was centered around São Paulo and Rio de Janeiro, then stretched south towards the border with Uruguay. Industries such as aircraft, petrochemicals and automobiles anchored Latin America's largest economy. But now Brazil's economic might has extended to regions of the country that had long underperformed compared to the wealthy south.

Records from Henry David Thoreau Reveal New Evidence of Climate Change
March 13, 2012 09:44 AM - David A Gabel, ENN

Henry David Thoreau was a famed naturalist, philosopher, and author who resided in Eastern Massachusetts from 1817 to 1862. He was also a leading abolitionist and advocator of civil disobedience in defiance of an unjust state. He is perhaps best known for his views on simple living uncluttered by overdevelopment embodied in his famous book Walden; or, Life in the Woods. As a naturalist, he made records for the flowering dates of a number of common plant species. Now, 150 years later, a team of biologists from Boston University (BU) have compared those flowering records with those of today. They found that the flowering date for 43 common species had moved up by an average of seven days since the time of Thoreau.

The Light in the Sky is NASA
March 12, 2012 04:23 PM - Andy Soos, ENN

There are many strange and ordinary lights in the sky. There are the stars, moon, planets and the Aurora Borealis for example. High in the sky, 60 to 65 miles above Earth's surface, winds rush through a little understood region of Earth's atmosphere at speeds of 200 to 300 miles per hour. Lower than a typical satellite's orbit, higher than where most planes fly, this upper atmosphere jet stream makes a perfect target for a particular kind of scientific experiment: the sounding rocket. Some 35 to 40 feet long, sounding rockets shoot up into the sky for short journeys of eight to ten minutes, allowing scientists to probe difficult-to-reach layers of the atmosphere. When they go up, they will release materials that will be visible milky white clouds which will make the jet stream velocity and direction trackable. There will be a new light in the sky just off the US Atlantic coast.

The Once Prolific Dugong
March 9, 2012 11:46 AM - Andy Soos, ENN

The dugong is a large marine mammal which, together with the manatees, is one of four living species of the order Sirenia. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century. Smithsonian scientists have discovered that this was not always the case. According to the fossil record of these marine mammals, which dates back 50 million years ago, it was more common to find three, or possibly more, different species of seacows living together in one locality at one time. This suggests that the environment and food sources for ancient seacows were also different than today. The team's findings are published in the journal PLoS ONE.

Reflecting on the Winter that Never Was
March 9, 2012 09:22 AM - David A Gabel, ENN

In a couple weeks, the northern hemisphere will be entering the spring season, and now is a good time to reflect on this winter. For some, it feels like spring has already been here, and soon summer will be approaching. That is because for many Americans, it was the winter that never was. According to the National Oceanic and Atmospheric Administration (NOAA), it was not the warmest winter in recent history, but it does rank pretty high. Furthermore, this winter will be marked for its amazing lack of snowfall, especially when compared with last year. The following are some highlights from around the nation.

Solar Power in Poor Rural Areas
March 8, 2012 03:12 PM - Editor, ENN

Solar power works best of course where the sun is brightest. However, another major factor is the capital cost for a solar installation. If your are poor, you cannot get started easily. One of the big opportunities positive climate action has presented the developing world is the chance to leapfrog a generation of energy technology straight into clean, green generation without the intervening capital intensive and dirtier aspects of energy technology. A British company thinks it has a potential and intriguing solution. Cambridge-based Eight19, named after the eight minutes and 19 seconds it takes light form the sun to reach earth, has developed this technology, and the business plan to tackle these challenges.

Gorilla Genome
March 8, 2012 02:41 PM - Andy Soos, ENN

The human genome is stored on 23 chromosome pairs and in the small mitochondrial DNA. Twenty-two of the 23 chromosomes belong to autosomal chromosome pairs, while the remaining pair is sex determinative. But that is human, what about one of our close relatives, the gorilla? Researchers announce today that they have completed the genome sequence for the gorilla - the last genus of the living great apes to have its genome decoded. While confirming that our closest relative is the chimpanzee, the team show that much of the human genome more closely resembles the gorilla than it does the chimpanzee genome. This is the first time scientists have been able to compare the genomes of all four living great apes: humans, chimpanzees, gorillas and orangutans. This study provides a unique perspective on our own origins and is an important resource for research into human evolution and biology, as well as for gorilla biology and conservation.

Overfishing the Mediterranean
March 8, 2012 09:37 AM - David A Gabel, ENN

The Mediterranean Sea has played host to some of the greatest civilizations that the world has ever seen. Today, it remains a hub of commerce and travel, connecting different parts of Europe, North Africa, and the Middle East. After the Suez Canal, it became the primary trading route to Asia. Over the years, millions of people have lived on its shores and exploited its resources. A new study recently released has found that after centuries of exploitation, the Mediterranean Sea is running out of resources. Many formerly healthy ecosystems have been wiped out.

The Future Environmental Impact
March 7, 2012 04:15 PM - Editor, ENN

As the developing nations change and their populations ask for amenities, energy and environmental issues will increase. As populations across the world grow, new research out of MIT shows the rising influence of large or developing countries in shaping our future global challenges. MIT's Joint Program on the Science and Policy of Global Change's 2012 Energy and Climate Outlook report projects that energy use could double by 2050. China alone could go from having about 50 million cars and trucks on the road to having about 300 million in less than 40 years. Fast-growing G20 nations – including Russia, Brazil, Mexico, China, India and other developing Asian countries – could put four times more vehicles on the road by 2050 than they have today.

Farms or Industry Pollution?
March 7, 2012 07:35 AM - Andy Soos, ENN

What to do when everything cannot be done at the same time? In present day Europe farm pollution as opposed to industrial pollution is gaining more attention and effort. While factories were once the big concern, more attention is focusing on pollution from farming, which accounts for more than half of land use in the EU and is overall the biggest consumer of water. Industrial releases once dominated the attention such as the sludge that broke through containment walls in the Hungarian town of Ajka in October 2010, the immediate concern was the safety of hundreds of nearby residents. In the end 10 people died from exposure and the toxic muck spilled into waterways, including the Danube, prompting alarms downstream. These spills are relatively rare and industrial pollution in many European rivers has declined since the 1960s. Tougher treatment laws, international cooperation and EU policies like the 2000 Water Framework Directive and 2006 Groundwater Directive are credited with the improvements.
