Today's news leftovers include Apple co-founder Steve Wozniak's house-selling struggles, scientists using the iPhone as a microscope, and an eight-year-old boy spending £1,000 on in-app purchases while playing a Simpsons game.

Here are the remains of the day for Friday 15 March.

No takers for Woz's house

Apple co-founder Steve Wozniak's multi-million dollar house in California is struggling to sell.

 

The 7,500-square-foot, six bedroom, six bathroom house was build by Wozniak in 1986 on a 1.19 acre plot of land, and features an indoor kids' play area and an outdoor kio pond with a waterfall, reports DNA. 

However, it failed to sell when it was put on the market in February 2012 for $5 million, so has now been put up for sale for a lower price of $4.395 million.

iPhone turned into microscope

The Telegraph has the story of scientists who have turned Apple's iPhone into a microscope by taping a £5 lens and a torch to the iPhone's camera.

The microscope was used to take pictures of stool samples to determine whether eggs, which are the main sign of intestinal worm infections, are present.

The iPhone photos detected 70 per cent of the infections in the study that was carried out on schoolchildren in rural Tanzania.

Boy racks up £1,000 iPad bill playing Simpsons game

Eight-year-old Theo Rowland-Fry from Bristol racked up a bill of almost £1,000 from downloading in-app purchases while playing a Simpsons game on his parent's iPad.

"Theo is only just eight and has no real concept of the monetary value attached," said the boy's father, Nick Rowland-Fry. "I appreciate children are their target audience but it is not right and there needs to be specific controls in place to stop this from happening."

Earlier this month, five-year-old Danny Kitchen, also from Bristol, unintentionally spent £1,700 by buying in-app purchases on free-to-play game Zombies vs Ninja.
