ISS Update: Kennedy Space Center Director Robert Cabana
NASA Public Affairs Officer Kyle Herring talks with Robert Cabana, Kennedy Space Center Director, about his career over the years with NASA and the space agency's future.
Selected as an astronaut by NASA in June 1985, Cabana is a veteran of four shuttle flights, including STS-41, STS-53, STS-65 and STS-88. He has also held a variety of management positions at NASA, including Chief of NASA's Astronaut Office, Deputy Director of the Johnson Space Center, Director of the Stennis Space Center and Di

Hearing Yourself Hear
Listen in as Artist Jacob Kirkegaard tells of his journey to hear himself hear. With the aid of researchers in Copenhagen, Kirkegaard generates an artificial tone in his own ear by playing two tones at a precise ratio. He has developed this phenomenon into an interactive sound piece he calls Labyrinthitis. (07:13)
Hungarian scientists discover remains of first freshwater 'mosasaur', an ancient lizard
Dec. 27 - Hungarian scientists discover ancient fossils of a new giant lizard species that lived in freshwater. A reconstruction of the 'mosasaur' has gone on display in the Hungarian Natural History Museum as the palaeontologists published their findings. Joel Flynn reports.

Jonathan Trent: Energy from Floating Algae Pods
Call it "fuel without fossils": Jonathan Trent is working on a plan to grow new biofuel by farming micro-algae in floating offshore pods that eat waste-water from cities. Hear his team's bold vision for Project OMEGA (Offshore Membrane Enclosures for Growing Algae) and how it might power the future. Not only does Jonathan Trent grow algae for biofuel, he wants to do so by cleansing waste-water and trapping carbon dioxide in the process. And it’s all solar-powered. (14:45)
Market Pulse: 12/12/12, a red letter day for Greek bonds
It's perhaps fitting that today Greek bond yields have a 12% handle for the first time since April last year. And is 88 years enough for progress on the "fiscal cliff" talks?
ECONOMY 2013: Luxury buyer weaker than last year - Saks CEO
Dec. 12 - Saks CEO Stephen Sadove says the high-end consumer is still reasonably healthy but not as strong as last year and feels the Fiscal Cliff's biggest impact will be on consumer sentiment.
Cultmapas urbanos [Urban cultmaps]
This research aims to address the catalog urban interventions as graffiti, stencil and sticker spotted in association with the city. As a result, they develop artistic urban mappings which assemble a structure marking the artistic manifestations. The urban arts, are georeferenced and eventually become part of a catalografia which can be viewed on the web entitled Cultmap art.

5 Summary Eutrophication is a process in which an ecosystem accumulates mineral nutrients. It can occur naturally, but is usually associated with human activity that releases nutrients into the environment. Anthropogenic eutrophication has caused a widespread loss of biodiversity in many systems. Recent attempts to reverse the process are proving difficult and expensive. Symptoms of eutrophication are most readily seen in aquatic sys
3.2.5 Sediments Sediments have a variable but complex role in nutrient cycling in most aquatic systems, and are a potential ‘internal’ source of pollutants. Release of phosphorus from lake sediment is a complex function of physical, biological and chemical processes and is not easy to predict for different systems. Nitrogen is not stored and released from sediments in the same way, so its turnover time within aquatic systems is quite rapid. Nitrogen concentrations tend to fall off relatively quickly foll
2.4.2 Saltmarshes Marsh plant primary production is generally nitrogen limited, so saltmarsh vegetation responds readily to the artificial eutrophication that is now so common in nearshore waters. Eutrophication causes marked changes in plant communities in saltmarshes, just as it does in freshwater aquatic and terrestrial systems. Biomass production increases markedly as levels of eutrophication increase. Increases in the nitrogen content of plants cause dramatic changes in populations of marsh plant consumer
1.2 Resource availability and species diversity A wide range of ecosystems has been studied in terms of their species diversity and the availability of resources. Each produces an individual relationship between these two variables, but a common pattern emerges from most of them, especially when plant diversity is being considered. This pattern has been named the humped-back relationship and suggests diversity is greatest at intermediate levels of productivity in many systems (Figure 1.5). 6.2 Non-covalent bonding in site-specific binding The affinity of a protein for DNA is determined in thermodynamic terms by the free energies of the individual components compared to the free energy of the DNA-protein complex. DNA binding proteins, which contain different binding motifs, demonstrate a wide range of thermodynamic strategies. The affinity of a site-specific DNA binding protein for its specific DNA sequence is generally of the order of 104−107 times greater than its affinity for non-specific sequen
