Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.

The United States should plan to store spent nuclear fuel in cooling pools and concrete-and-steel casks for 100 years as it sorts out what should be done with it in the long term, according to a new study from MIT. Storing spent fuel temporarily, the study argues, is in some ways better than immediately transferring it into permanent underground storage at facilities like the proposed one at Yucca Mountain.

ew research from the UK's National Physical Laboratory (NPL) is helping Duvas Technologies Ltd (Duvas) to develop improved air quality monitoring instrumentation. Currently over 1bn people a year suffer from respiratory disease associated with pollution, and according to the World Health Organisation, over 3m a year die from its effects. Duvas is planning to help provide technology to understand and address this problem.

Germany on Monday announced plans to become the first major industrialised power to shut down all its nuclear plants in the wake of the disaster in Japan, with a phase-out due to be wrapped up by 2022.

The US government on Tuesday approved a plan to build the country's first offshore wind farm, in a picturesque bay near Cape Cod, a popular Massachusetts holiday destination.

Smartphone apps may be the key to getting people out of their cars and onto mass transit. An interesting study of commuters in Boston and San Francisco found people are more willing to ride the bus or train when they have tools to manage their commutes effectively. The study asked 18 people to surrender their cars for one week. The participants found that any autonomy lost by handing over their keys could be regained through apps providing real-time information about transit schedules, delays and shops and services along the routes. Though the sample size is small, the researchers dug deep into participants' reactions. The results could have a dramatic effect on public transportation planning, and certainly will catch the attention of planners and programmers alike. By encouraging the development of apps that make commuting easier, transit agencies can drastically, and at little cost, improve the ridership experience and make riding mass transit more attractive.

China said Thursday it will increase this year's production quota for rare earths but gave no sign it might reverse plans to cut exports of the exotic metals needed by high-tech industry.

A high-tech entrepreneur has unveiled plans to launch the world's most powerful rocket since man went to the moon.

This Friday is not just any old Friday, but it is the kick off of Easter weekend.  In Christianity, of course, this weekend is the celebration of Christ's crucifixion and eventual resurrection and ascension into heaven.  Whether it was planned or a coincidence, This Week's Christiane Amanpour sat down with the Reverend Franklin Graham, son of legendary evangelist Billy Graham.  The topics of social media and the second coming of Christ were among those discussed.

Bloomberg's office says the new initiatives include plans to build solar power plants on capped landfills and launch a loan program to help property owners pay for green energy efficiency upgrades.

"Researchers at Yale, Texas A&M and Boston University predict that by 2030 urban areas will expand by more than 463,000 square miles, or 1.2 million square kilometers. That is equal to 20,000 American football fields becoming urban every day for the first three decades of this century. The growth in urban areas will coincide with the construction of roads and buildings, water and sanitation facilities, and energy and transport systems that will transform land cover and cities globally. Recent estimates suggest that between $25 trillion and $30 trillion will be spent on infrastructure worldwide by 2030, with $100 billion a year in China alone."

Climate scientists have told city planners that based on current trends, Chicago will feel more like Baton Rouge than a Northern metropolis before the end of this century. So, Chicago is getting ready for a wetter, steamier future. Public alleyways are being repaved with materials that are permeable to water. The white oak, the state tree of Illinois, has been banned from city planting lists, and swamp oaks and sweet gum trees from the South have been given new priority. Thermal radar is being used to map the city's hottest spots, which are then targets for pavement removal and the addition of vegetation to roofs. And air-conditioners are being considered for all 750 public schools, which until now have been heated but rarely cooled.

On the heels of another halting round of talks on climate change, UN scientists this week will review quick-fix options for beating back the threat of global warming that rely on technology rather than political wrangling.

There is a vitally important national and state-level discussion taking place about how to address the government's frighteningly large deficits while limiting disruptions for all Americans. But while federal and state actions affect us all, much of what concerns Americans most directly and personally happens closer to home and increasingly, this means in our cities. Budget cuts simply can't derail efforts to make our cities smarter. Today our nation's cities are facing a "perfect storm." For many cities, their populations are growing at the same time that their budgets are shrinking. Today, for the first time, more than 50% of the world's population lives in cities. In the last decade large metropolitan areas in the U.S. grew by a combined 10% - nearly double the rate of the rest of the country. Our large metro areas now house two thirds of America's total population. They have become the dominant forces in our economy and society.

City buildings create their own microclimates. Ignoring these variations can make life uncomfortable for inhabitants and prevent buildings from achieving true energy efficiency, according to Evyatar Erell, a professor of architecture at Israel's Ben-Gurion University of the Negev."Even when architects design a green building, it may not make the best use of the environment because other buildings get in the way," he said.

Back in 2009 Mayor Bloomberg prohibited vehicle traffic on Broadway between 42nd Street and 47th Street in Times Square to create a pedestrian plaza (video here). Now, the city's most recent Community Air Survey found that, "After the conversion to a pedestrian plaza, NO pollution levels in Times Square went down by 63 percent while, NO2 levels went down by 41 percent." Unlike N2O, which makes you laugh at Phish shows, NO2, or nitrogen dioxide, destroys your lungs and may cause Sudden Infant Death Syndrome. Nitric oxide (NO) isn't good for you either.
