Glaciers are massive sheets of ice, sliding slowly down a mountain and carving enormous grooves in the land. They flow down to the lowest point where gravity can take them, often into the ocean. The normal school of thought for these "tidewater glaciers" said that due to their weight and compaction to the earth's surface, they were grounded on the sea floor, only to arise once disintegrated. However, there is one glacier that extends into the water, floating intact on the ocean waves.
President Obama Focuses on Advanced Battery and Electric Vehicle Manufacturing
July 17, 2010 02:54 PM - Exclusive to ENN, Douglas Elbinger
As part of the Economic Recovery Act, Obama administration officials fanned out across the nation this week in a series of ribbon-cutting and ground-breaking ceremonies to highlight their commitment to renewable energy, especially projects that are creating jobs in advanced battery manufacture. Senior Administration officials will travel to eight Recovery Act advanced battery and vehicle project sites nationwide where work has begun constructing new manufacturing plants, adding new manufacturing lines, building electric vehicles, and installing electric vehicle charging stations. This series of events was emphasized by President Obama on Thursday, July 15th, at Compact Power, Inc. where he officially "broke ground" on a new advanced battery manufacturing factory in Holland, Michigan. After brief introductions by Peter Ban-Suk Kim, Chief Executive Officer of LG Chem Ltd., Michigan Governor Jennifer Granholm, and Holland Mayor Kurt Dykstra, the president spoke for about fifteen minutes reiterating his progress in advance battery manufacturing and job creation.

The brain has always been a bit mysterious. How does it all work so that a human being can live, breathe and talk. The brain is composed of two broad classes of cells: neurons and glia. These two types are equally numerous in the brain as a whole, although glial cells outnumber neurons roughly 4 to 1 in the cerebral cortex. Glia come in several types, which perform a number of critical functions, including structural support, metabolic support, insulation, and guidance of development. Astrocytes (brain cells named after their characteristic star-shape) that were previously thought to act only as the glue between neurons have a central role in the regulation of breathing.
Lakes on Titan
July 15, 2010 04:35 PM - Andy Soos, ENN
Titan, is the largest moon of Saturn, the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found. On Earth, lake levels rise and fall with the seasons and with longer term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake level changes on Saturn's largest moon showing that is possesses a similar change cycle

Horses and Burros
July 14, 2010 07:27 PM - Andy Soos, ENN
One does not think often about vast herds of horses or burros. However, there are a few herds here and there and they need to be protected and maintained. The Bureau of Land Management (BLM) announced today that it has issued a new policy handbook relating to the management of wild horses and burros roaming public lands under the BLM's jurisdiction. Among other things, the handbook would ensure that the factors considered in determining appropriate herd population levels are consistent across all of the Bureau's 179 herd management areas in 10 Western states.
EPA Proposes Transport Rule to Aid Downwind States
July 14, 2010 10:36 AM - David A Gabel, ENN
A new EPA proposal is taking aim at reducing emissions from power plants that affect people living downwind. Air pollution from these sources has been shown to cause thousands of asthma cases and other cardio-respiratory impairments. The proposed regulations have been termed the "transport rule" because it is designed to address the eastern United States, across which the pollution is transported.
The Rising Indian Ocean
July 13, 2010 04:33 PM - Andy Soos, ENN
Changing sea levels have happened before and will happen again in a dynamic world. Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder. The study, which combined sea surface measurements going back to the 1960s and satellite observations, will threaten inhabitants of some coastal areas and islands.
EPA Proposes New Maximum Achievable Control Technology Standards for Boilers and Incinerators
July 13, 2010 09:47 AM - David A Gabel, ENN
The EPA has published new rules in the Federal Register regarding new Maximum Achievable Control Technology (MACT) for boilers and incinerators. The target of the new rules is to limit toxic emissions and mercury, which is known to be extremely harmful to human health. The Federal Register is available to the public, and the EPA will be accepting public comments on these rules through August 3, 2010.
June Heat in the US

It is summer and it is traditional to complain about how warm it is. Weather also is always a popular subject. The National Oceanic and Atmospheric Administration (NOAA) State of the Climate report shows the June 2010 average temperature for the contiguous United States was 71.4 degrees F, which is 2.2 degrees F above the long-term average (1901-2000). The average precipitation for June was 3.33 inches, 0.44 inch above the long-term average.
