The new ‘supercavitation’ methodology could see the vehicles travel at rates up to 3,600 mph underwater, being able to make the trip from Shanghai to San Francisco in about two hours. BY  DAVID HARDING    NEW YORK DAILY NEWS   Sunday, August 24, 2014, 1:54 PM Chinese scientists are working on creating a submarine that would be able to travel at speeds up to 3,600 mph. Previous Next   Enlarge It is a   distance of more than 6,100 miles. But a team of Chinese scientists claim to have moved closer to developing a supersonic submarine, which could complete the journey from Shanghai to San Francisco in less than two hours. Researchers from the Harbin Institute of Technology say they have developed a way to make a submarine — or torpedo — to travel at extremely fast speeds underwater. Li Fengchen said his team of scientists can now create the complicated air "bubble" required for fast travel undersea. This bu...

Scientists have replicated a crucial photosynthetic reaction for the first time, taking them a step closer to creating sustainable, cheap fuel from water and sunlight - just like plants do. FIONA MACDONALD    WEDNESDAY, 27 AUGUST 2014 Image:  Australian National University Plants use  photosynthesis  to turn water, carbon dioxide and sunlight into oxygen and the energy they need to power their systems. And for decades scientists have been trying to replicate this reaction in order to create biological systems that can produce cheap, clean hydrogen fuel. Now, for the first time ever, scientists from the Australian National University in Canberra, Australia, have managed to modify a naturally occurring protein, and use it to capture energy from sunlight, a key step in photosynthesis. Their results have been published in  BBA Bioenergetics . “Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and ...
