Study: Today's Teenagers May Be Most Out-of-shape In US History
November 22, 2011 10:12 AM - David A Gabel, ENN

A report from Northwestern University in Chicago looks at the status of the cardiovascular health of current adolescents in the United States, and its findings were not encouraging. It says that teens today have a higher likelihood of dying at a younger age than today's adults. The causes listed include high blood sugar, obesity, poor diet, smoking, and limited exercise. Of course this is not true for all teenagers; some may be in better shape than the rest of us will ever be. However, in the case of teenage health, the lows outweigh the highs, bringing average teen health to a dismal level.

Population Control

In this day and age most societies worry about too large a population increase. However, there is always another point of view. Worried about its dwindling numbers, the Roman Catholic church in southern India is exhorting its flock to have more children, with some parishes offering free schooling, medical care and even cash bonuses for large families. The strategy comes as India’s population tops 1.2 billion, making it the second most populous country in the world after China, and runs counter to a national government policy of limiting family size.

Exoplanet Count to 700

One can look up and count the stars that can be seen. Finding exoplanets orbiting these stars is a different matter because they cannot be seen by the naked eye. There are two main counters of the exoplanents: NASA and the European count. NASA is more conservative while Europe will include the new exoplanet when it is announced. So Europe will also be slightly more. The count topped 500 in November 2010, and it passed 600 just two months ago when scientists with the European Southern Observatory announced 50 newfound planets, including one super-Earth that might be a good candidate for hosting life. Now it is 700.

The Contribution of Peatland CO2 to Climate Change
November 21, 2011 10:06 AM - David A Gabel, ENN

Peat, the accumulated turf made up of decayed vegetation, forms in many parts of the world in places like bogs, moors, and swamp forests. Due to its high carbon content, it can be harvested and burned as fuel. There are estimates that the global inventory of peat, covering 2 percent of all land area, contains 8 billion terajoules of energy. A new study has revealed that peat also has a high potential to contribute to climate change. The study, published by researchers from Bangor University in Maine, found that drought causes the release of far more carbon dioxide from peat than previously assumed.

The World Carbon Cycle in the Last Ice Age
November 21, 2011 09:32 AM - Andy Soos, ENN

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. It is one of the most important cycles of the earth and allows for carbon to be recycled and reused throughout the biosphere and all of its organisms. Has it always been the same? A reconstruction of plant productivity and the amount of carbon stored in the ocean and terrestrial biosphere at the last ice age has just been published in Nature Geoscience. The research by an international team of scientists greatly increases our understanding of natural carbon cycle dynamics.

Climate Extremes to Come

The weather has always been an interesting variable in the lives of every person. What impact will global warming have? Will there more extreme weather behavior? A new report from the Intergovernmental Panel on Climate Change (IPCC) says that an increase in heat waves as well as hurricanes, floods, and droughts will likely become more intense in the next century. The United Nations IPCC's new special report on extreme weather, which includes a range of possible scenarios based on future greenhouse gas emissions, urges governments worldwide to draft plans to minimize the likely human and economic costs of these weather phenomena.

Galactic Process
November 18, 2011 08:14 AM - Andy Soos, ENN

New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years. This ongoing recycling keeps some galaxies from emptying their fuel tanks of interstellar gas and stretches their star-forming epoch to over 10 billion years.

Starving Bacteria
November 17, 2011 04:52 PM - Andy Soos, ENN

Though it was known in the nineteenth century that bacteria are the cause of many diseases, no effective antibacterial treatments were available back then. In 1910, Paul Ehrlich developed the first antibiotic. Bacteria are also notorious for existing antibiotic treatments. A new study is showing that bacteria that are starving tend to resist antibiotics better. During an infection there is a tendency to starve bacteria under certain conditions. How can this be reversed? "Bacteria become starved when they exhaust nutrient supplies in the body, or if they live clustered together in groups know as biofilms," said the lead author of the paper, Dr. Dao Nguyen, an assistant professor of medicine at McGill University.

New "Super" Mouthwash Under Development May Eliminate Cavities
November 17, 2011 08:42 AM - David A Gabel, ENN

Generic mouthwash does a fantastic job cleaning out your mouth and leaving you with a minty fresh feeling. Now there is a new kind of mouthwash which is under development, that has the potential to eliminate tooth decay and cavities. Developed at the UCLA School of Dentistry, the mouthwash utilizes a new type of anti-microbial technology. A recent clinical study, involving 12 subjects showed remarkable results. Those who rinsed just once with the new mouthwash almost completely eliminated the S. mutans bacteria, known to cause tooth decay.

Gamburtsev Mountain Birth
November 17, 2011 07:30 AM - Andy Soos, ENN

The Gamburtsev Mountain Range (also known as the Gamburtsev Subglacial Mountains) is a subglacial mountain range located in Eastern Antarctica. The current speculated age of the range is over 34 million years[6] and possibly 500 million years. The birth of the Gamburtsev Subglacial Mountains buried beneath the vast East Antarctic Ice Sheet — a puzzle mystifying scientists since their first discovery in 1958 — is finally solved. The remarkably long geological history explains the formation of the mountain range in the least explored frontier on Earth and where the Antarctic Ice Sheet first formed. The findings are published this week in the journal Nature
