Scientists to study impact of gulf oil spill on marine food webs. Shells from oysters, clams, and periwinkles hold clues about the ways and rates at which harmful compounds from the spill are being incorporated into the Gulf's marine food web. New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? (Source: Science Magazine)

More than 6,000 different species living on the sea-floor have been identified so far and more than half of these are unique to the icy continent. A combination of long-term monitoring studies, newly gathered information on the marine life distribution and global ocean warming models, enable the scientists to identify Antarctica's marine "biodiversity hotspots". Researcher Griffiths describes how krill populations (the shrimp-like invertebrates eaten by penguins, whales and seals) are reducing as a result of a decrease in sea-ice cover. A much smaller crustacean (copepods) is dominating the area once occupied by them. This shifts the balance of the food web to favour predators, like jellyfish, that are not eaten by penguins and other Southern Ocean higher predators. Sea-ice reduction is also affecting penguins that breed on the ice.

Government officials and Quantico Marine base have blocked official visits to PFC. Bradley Manning by Rep. Dennis Kucinich, Amnesty International, and the UN Special Rappateur on torture. According to Manning's attorney, Kucinich, Amnesty, and UN have been trying to get clearance for "official visits" to Manning at the Quantico Marine brig. An "official visit" is different from an "authorized visit" in that an "authorized visit" - one made by family or friends and approved by the brig and Manning - is subject to full surveillance by the brig. An official visit would be one conducted by those officials on government business, and would not be subject to monitoring by the brig. So essentially, the government and the brig are saying you can come visit Manning, but we're going to watch and record every thing you say, and those recordings could be used as evidence against Manning at his trial. Manning's attorney stated that Kucinich, Amnesty, and the UN are not allowed to have an official visit "because none of these individuals are conducting 'official government business.'" This is, of course, ludicrous. Rep. Kucinich is a sitting Member of Congress with a seat on the Oversight Committee, and he submitted official notices to the Department of Defense that he wanted to inspect the conditions of Manning's confinement. Additionally, the UN Special Rappateur on Torture has opened an investigation into Manning's detention and would be visiting in his official capacity. What is the government afraid that Manning will say to these officials when the Brig isn't able to record his every move? If Manning's torture is "meeting our basic standards," as President Obama says, what is there to hide?

For the second time, a General has publicly questioned the policies of his Commander-in-Chief. This time, the Marine Corps Commandant is displeased with Obama's desire to abandon Don't Ask, Don't Tell. Whether you agree with DADT or not, generals should not take their criticisms public.
