Rolls Royce develops propulsion system for flying taxi

Technology
Engine maker Rolls-Royce has designed a propulsion system for a flying taxi which it says could take to the skies as soon as early next decade.The British firm said it had drawn up plans for an "electric vertical take-off and landing" (EVTOL) vehicle, which could carry four to five people.The vehicle could travel at speeds of up to 250 mph (402 km/h) for approximately 500 miles, it said. Rolls joins a variety of other firms in seeking to develop flying vehicles.Speaking ahead of this week's Farnborough Airshow, Rob Watson, head of the company's electrical team, said: "We are well placed to play a leading role in the emerging world of personal air mobility and will also look to work in collaboration with a range of partners."Flyin...
Russia blasts Greece over cybercrime suspect's extradition

Russia blasts Greece over cybercrime suspect's extradition

Technology
A Greek court agreed Friday to extradite a Russian cybercrime suspect to France, a decision the Russian government protested and which could further sour relations between the two countries after Greece expelled two Russian diplomats. The court in the northern city of Thessaloniki ruled in favor of France's request to take custody of Alexander Vinnik, a former bitcoin operator who was arrested in Greece last year on a U.S.-issued warrant. Vinnik, 38, also is wanted on criminal charges in the United States and Russia. The ruling was made a day after Greek authorities confirmed that two Russian diplomats were being expelled for allegedly providing protest funding in an attempt to keep neighbor Macedonia from joining NATO. The Russian Foreign Ministry indicated it was considering reprisals....

Iceberg 4 miles wide breaks off from Greenland glacier

Iceberg 4 miles wide breaks off from Greenland glacier

Technology
An iceberg four miles (six kilometers) wide has broken off from a glacier in eastern Greenland and scientists have captured the dramatic event on video. New York University professor David Holland, an expert in atmospheric and ocean science, told The Associated Press that "this is the largest event we've seen in over a decade in Greenland." A June 22 video of the incident was taken by his wife, Denise Holland of NYU's Environmental Fluid Dynamics Laboratory. They had camped by the Helheim Glacier for weeks to collect data to better project sea level changes due to global warming. Holland said Wednesday that the time-lapse video, which is speeded up 20 times, shows "3 percent of the annual ice loss of Greenland occur in 30 minutes." "It sounded like rockets going off," he said, describing...
8 endangered black rhinos die in Kenya after relocation

8 endangered black rhinos die in Kenya after relocation

Technology
Eight critically endangered black rhinos are dead in Kenya after wildlife workers moved them from the capital to a new national park, the government said Friday, calling the toll "unprecedented" in more than a decade of such transfers. Preliminary investigations point to salt poisoning as the rhinos tried to adapt to saltier water in their new home, the Ministry of Tourism and Wildlife said in a statement, describing how the animals likely became dehydrated and drank more salty water in a fatal cycle. The ministry suspended the ongoing move of rhinos and said the surviving ones in the new park were being closely monitored. The loss is "a complete disaster," said prominent Kenyan conservationist Paula Kahumbu of WildlifeDirect. Conservationists in Africa have been working hard to protect ...
