With high oil prices, dwindling fuel supplies and a growing pressure to reduce global warming, governments are looking for brilliant ideas. Why don’t consider the sea? Waves are a powerful source of energy and in the last years a growing attention is producing a wide range of prototypes. Machines of various shapes and sizes are being tested in last years to see how they could capture waves and tides to create “marine” energy.
A new experiment comes from Michele Grassi, researcher at the department of math at the University of Pisa, in the centre of Italy, who built a prototype of a wave-trapping machine.

It’s not only the Gulf of Mexico that’s suffering from “dead zones” caused by excess nutrients, such as nitrogen and phosphorus used as fertilizers.
Marine dead zones are spreading in the Baltic sea, and that could cause the entire ecosystem to collapse for lack of oxygen. Dire warnings from Lasse Gustavsson, Swedish head of the World Wildlife Funds branch in Sweden.

We’re at the beginning of June and it’s still raining. Despite this unmerciful weather, summer season is coming and Italian coasts are preparing to host bunch of tourists from around the world. Such as every year, a list of best beaches is revealed by the Blue Flag Programme, responsible for monitoring popular public beaches, resorts and marinas throughout the world. Criteria such as water quality, amenities and general safety, as well as nearby cultural attractions are all taken into account before a “Blue Flag” is awarded.
This year the Blue Flag programme, owned and run by the independent non-profit organization Foundation for Environmental Education (FEE), has declared Italy’s nicest beaches can be found in the Tuscany and Marche regions, with each region boasting 15 awards. Overall, 215 beaches in 104 Italian communities received a “Blue flag”, eight more than last year and 14 more than in 2006. While last year many southern Italian beaches failed to gain the coveted symbol because of problems with waste disposal, this year they have had greater success.
