According to the authors "… a male orangutan , clinging precariously to overhanging branches , flails the water with a pole , trying desperately to spear a passing fish … The extraordinary image , a world exclusive , was taken in Borneo on the island of Kaja … This individual had seen locals fishing with spears on the Gohong River . Although the method required too much skill for him to master , he was later able to improvise by using the pole to catch fish already trapped in the locals ’ fishing lines .

Geobacter sulfurreducens is a species that normally has the ability to produce electricity by reducing organic carbon compounds , but researchers at the University of Massachusetts have managed to engineer a strain that can produce electricity using only hydrogen gas as an electron donor and carbon dioxide as a source of carbon .

Mechanical engineer Anjan Contractor received a $ 125 , 000 grant from the agency to build a prototype 3 D printer with the aim of automating food creation . It ' s hoped the system could provide astronauts food during long - distance space travel , but its creator has the loftier aim of solving the increasing food shortages around the world by cutting down on waste . The software for the printer will be open - source , while the hardware is based on the open - source RepRap Mendel 3 D printer . The concept is to use basic " building blocks " of food in replaceable powder cartridges . By combining each block , a wide range of foods should be able to be created by the printer . The cartridges will have a lifespan of 30 years , more than long enough to enable long - distance space travel . After proving his system works on a basic level by printing chocolate , Contractor will start his project within the next few weeks by attempting to print a pizza . As Quartz reveals , the pizza printer will first print a layer of dough , which will be cooked while being printed , before mixing tomato powder with water and oil to print a tomato sauce . The topping for the pizza will be a nondescript " protein layer . " It ' s early days for the project , but if it ' s successful it would be a real milestone on the way towards a Star Trek - style Replicator . http : / / www . theverge . com / 2013 / 5 / 21 / 4350948 / nasa - funding - 3 d - food - printer - pizzahttp : / / en . wikipedia . org / wiki / Nikolai _ VavilovMouse Attacks Snake to Save FriendAt Hangzhou Zoo in Zhejiang province , eastern China , zookeepers witnessed an unusual sight after two live mice were placed in a snake ’ s enclosure for supper . Defying the natural order ( snake eats mouse , mouse passively complies ) , this astonishing set of images shows what happens when one plucky rodent is unwilling to let a viper take his friend . According to the keeper , the second mouse usually hides while the snake devours his or her mate . But after dinner had started , the other mouse attacked the snake and bit him as it tried to kill its friend . While it was too late to save him / her , the attacking mouse was given his freedom after the keeper felt he ’ d earned his right to live . Imagine what would happen to the world if humans also have such love and respect for each other . Auroras shine over a waterfall in Iceland in one of our favorite Photo of the Day images from April .

In February 2012 , doctors at the University of Michigan saved the life of now 20 - month - old Kaiba Gionfriddo by implanting a 3 - D printed splint to hold the trachea open . Over the next couple of years , Kaiba ’ s body will absorb the biopolymers of the splint . Before the transplant , his windpipe would collapse and he would need to be resuscitated daily . Over a year after the transplant , Kaiba has had no difficulty breathing .

It was first discovered by French explorer Jacques Cousteau , and was formed over a period of around 140 , 000 years when the sea levels were much lower than they are now . As the sea levels rose , a number of limestone caves were flooded over time to create this almost perfect circle . It ' s now home to several species of fish and reef shark .
