If you're not worried about a future without toro sushi or rare tuna steaks, you probably should be. Five of the eight species of this tasty marine predator are endangered, according to the International Union for the Conservation of Nature, source of the Red List of threatened species. In January 2013 an international group of fisheries researchers told the world (PDF) that Pacific bluefin tuna had been fished to their lowest levels in history, with the population near to collapsing as a commercial stock.
The researchers don't claim the device could be used to create electricity, at least not yet. But it could relatively easily be scaled up to make fresh water out of salt water via distillation, for example, or to sterilize medical or food-processing equipment in areas of the world where electricity is hard to come by, said MIT researcher Hadi Ghasemi in a statement.
The Hanwha Eagles of Daejeon, Korea, have been on a long losing streak, the BBC reports… but they are winners in our hearts here at Popular Science. That's because they have decided to amp up their fans by giving them access to three rows of telepresence robots. Not able to score a ticket to an Eagles game? No problem. These robots will be able to cheer, chant, show the faces of remote fans on their own screen faces, and hold up LED panels showing encouraging texts from fans.
Yesterday, Chinese authorities finally lifted a nine-day quarantine of 151 individuals from the northwestern city of Yumen, instituted after a 38-year-old man died of a bubonic plague infection last week. Entry and exit points were also sealed off, trapping nearly 30,000 residents. In the end, no other cases of bubonic plague developed.
Polar bears are the largest land predators in the world. Confined to arctic climes, they are huge, powerful swimmers, and deadly hunters. In addition to being the second-best bear, they risk going extinct from global warming's environmental changes. Thanks to an offering by a luxury cruise line, customers can take a cruise through the newly navigable arctic, and try to see polar bears struggling to stay alive on what remains of Arctic ice.
On Wednesday the 23rd of July, a team of UNSW students successfully attempted to break a 26 year old world speed record for the fastest electric vehicle over 500 kilometres. The team broke the record, but is still waiting for final approval from the world Motorsport governing body, FIA. The car averaged a speed of more than 100 km/h during the attempt, beating the previous world record of 73 km/h.
US based Mad Scientist Nick Klein built the poop powered flame thrower for the National Geographic's show Doomsday Preppers. Impressively the device can shoot flames up to 10 meters but probably doesn't smell too good. While environmentally friendly as far as flame throwers go, how and why does one build a poo powered flame cannon?
Nuclear bombs are seen as weapons of mass destruction, but some scientists imagined their use for good. Controlled explosions could be used to divert rivers, dig reservoirs, drill for oil and even create natural harbours. Located in Kazakhstan, Lake Chagan was one of these tests, performed by the Soviet Union in 1965. A 408m wide, 100m deep crater created with a 140 kiloton nuclear explosion. But would you really want to swim in it?
So DARPA wants a reusable spaceplane. I mean, who doesn't? For decades, space experts have tried to design quick-turnover, reusable launch systems. So far, however, no one has made one that works. "There really isn't any kind of vehicle today that does exactly what they're asking people to do," Micah Walter-Range, director of research and analysis at the Space Foundation, tells Popular Science. "You can certainly compare it to existing vehicles, but it seems to be a new class."
