Deep-Sea Drug Discovery. Pacific Ocean natural products isolated from marine mollusks and sponges can reverse multidrug resistance in cancer cells Many marine natural products show anticancer activity, but some can reverse multidrug resistance in cancer cells. A new investigation by Robert J. Capon of the University of Queensland correlates the products' structures with their activity. The oceans are a treasure trove of naturally produced chemical compounds with impressive and varied biological activity. One class of these compounds, the lamellarins, has some members that are cytotoxic, while others are able to reverse multidrug resistance in certain cancer cells.

These lamellarins act by inhibiting the so-called P-glycoprotein, which enhances transport of anticancer agents out of cancer cells, thus rendering the cells multidrug resistant. Capon's team set out to determine the structures of a variety of lamellarins and correlate them to the activity of the compounds. Author: Robert J. Robert J. Overfishing - The consequences.

Eat more sustainable seafood with Seafood Watch. If you care about the health of the world's oceans, you have likely become aware in recent years of the harmful effects of overfishing. With Seafood Watch, a free iOS app, you'll have a handy pocket guide to help you find seafood that is fished or farmed using sustainable methods. The app gets its data from the Monterey Bay Aquarium Seafood Watch program, which uses "a science-based, peer-reviewed process" to encourage "consumers and businesses to purchase seafood that is fished or farmed in ways that don't harm the environment. " With the app, you can look up a particular type of fish to see if it is a Best Choice, Good Alternative, or something to Avoid. You can also look up restaurants and markets in your area that feature ocean-friendly seafood, and you can add places you've found that offer it.

From the app's home screen, you can use the search field to look up a type of fish to see how it rates on Seafood Watch's scale. 333-AZUL ( teaser ) Ocean News: World Oceans Day 2010. New Study Reveals Resistance To Ocean Acidification Worsened By Warming The living tissues and external organic layers of marine calcifiers such as corals and mollusks may play a large, but previously unappreciated, role in protecting these organisms from the corrosive effects of sea water, according to a paper published online in Nature Climate Change on August, 21 2011. Using a series of transplantation experiments along a natural marine CO2 gradient found off the island of Ischia in Italy, Riccardo Rodolfo-Metalpa and colleagues show that corals and molluscs are able to calcify and grow at faster than normal rates when exposed to the high carbon dioxide levels that are projected for the next 300 years.

The team suggests that although calcifiers continue to accrete shell or skeleton beneath healthy tissue, there is still risk of exposed shells and skeletons dissolving as pH levels fall, and only those with intact external protective layers remain protected. Can Oceans Solve Our Water Problem ? | Learn Science at Scitable. Now that we have established why we have a freshwater problem, I wonder "Why don't all the African countries use the seawater? " Since we live on the "Water Planet", we have to look for alternatives and the first one to come to mind is "seawater" !!! Africa is surrounded almost completely by 2 oceans (Atlantic and Indian oceans) and 2 seas (Mediterranean and Red seas). Wouldn't it be more feasible for ─at least the coastal countries─ to use these enormous sources? First, what is the difference between "Seawater" and "Freshwater" ?

The difference between them is the concentration of salts and minerals. Second, why does seawater have a higher content of salts despite that the water cycle starts with evaporation of seawater ─leaving the salt behind─ and freshwater rain ? The answer is very simple... " Weathering or surface erosion of mountains and rocks dissolve more salts in the water, and thus raising the salt content of oceans higher than freshwater's.

The First-Ever Comprehensive Assessment of Ocean Health The Ocean Health Index gives the world’s ocean a “65” out of “100.” The Index charts new territory, and for the first time ever sets up a world standard for gauging ocean health. Scientists and marine experts calculated sustainable standards for the many ways we use the ocean, and offer hard numbers to show how close or far each country is to a balanced use of the sea. You can view the project and results at ​www.oceanhealthindex.org​ Researchers hope that the Ocean Health Index builds awareness of the state of the world’s ocean, and works as a catalyst and guide for business and government decision-makers to develop effective policies promoting ocean health.

The Goals: Establish a new world standard for measuring ocean healthInfluence decision-makers and raise global awareness to generate positive and dramatic action for improved ocean governance and healt Ten Hu​man Goals Why it's time for the Ocean Health Index. An Index for Ocean Health. ReutersThe beluga whale is threatened by mercury and PCBs in the Arctic Sea. What has been billed as the “Dow Jones of ocean health” is six months from release, and Ben Halpern is feeling the pressure. “We’re frantically wrapping up analyses,” Dr. Halpern, a research biologist at the University of California at Santa Barbara, said in a telephone interview. Just as traders use various stock indices to monitor the global economy, micro-analyzing each blip, a team of nearly 50 scientists from many disciplines is designing an analogous tool to track the health of the world’s oceans and the implications for human well-being.

(Dr. With a maximum possible score of 100, the number measures how well a country fares in achieving optimal oceanic conditions and management practices; the lower the score, the worse conditions are. Water cleanliness is, for example, subdivided into pathogens, chemical pollution, nutrient pollution, toxic contamination, trash and so forth. Flower Garden Banks National Marine Sanctuary Setting. NATURAL SETTING The natural setting in which Flower Garden Banks National Marine Sanctuary is situated is the key to protecting this national treasure. It is crucial that we understand the complexities of the sanctuary's local ecosystem and the interplay of individual plant and animal populations. It is also vital that we understand the larger context of the surrounding Gulf of Mexico ecosystem and watershed that influence, and are influenced by, the sanctuary. Gaining this understanding is a continuous process.

Salt Domes Coral Reef Formation Regional Context Currents Watershed Connectivity Another great tool for learning about the sanctuary and the surrounding region, is the interactive map compiled by NOAA's National Coastal Data Development Center (NCDDC) using sanctuary data.
