Desert safari lovers and dune bashers have a great chance to win an iPad 2 in our science competition this week.
Play our "Do You Know …", which was created by the Swiss university Ecole Polytechnique Federale de Lausanne (EPFL), and running on www.thenational.ae and in its Frontiers section in The National.
There is new question each Sunday, prompting readers to discover how much they know about the UAE and its culture from a scientific perspective.
Michael Mitchell, who developed the competition, said the questions were harder than they might seem but the idea of the competition was all about promoting research and learning. For example last week the competition asked how do mangroves absorb oxygen in muddy water? Click here to discover the answer.
Readers have a week to answer each question before the correct answer is published the following Sunday, together with a new question. Entry for this week's question closes at midnight Sunday, when entry for the following week's question begins.
Each correct answer will give participants an increased chance of winning the competition, with the top three finishers winning an iPad and a solar-powered keyboard.
EPFL, which has a branch in Ras Al Khaimah, is known for many scientific developments, including the first modern computer mouse in the 1980s.
The solar panels inside the keyboards being given away as prizes, called dye-sensitised solar cells, are also an EPFL technology. They operate using a process that imitates photosynthesis.
The winners will be announced in August.

- The introduction of tariffs could hinder the US's clean energy initiatives by raising input costs for materials like nickel
- US domestic suppliers might benefit from higher prices, but overall oil consumption is expected to decrease due to elevated costs

What is double taxation?
- Americans living abroad file taxes with the Internal Revenue Service, which can cost hundreds of dollars to complete even though about 60 per cent do not owe taxes, according to the Taxpayer Advocate Service
- Those obligations apply to millions of Americans residing overseas – estimates range from 3.9 million to 5.5 million – including so-called "accidental Americans" who are unaware they hold dual citizenship
- The double taxation policy has been a contentious issue for decades, with many overseas Americans feeling that it punishes them for pursuing opportunities abroad
- Unlike most countries, the US follows a citizenship-based taxation system, meaning that Americans must file taxes annually, even if they do not earn any income in the US.

The chef's advice
Troy Payne, head chef at Abu Dhabi’s newest healthy eatery Sanderson’s in Al Seef Resort & Spa, says singles need to change their mindset about how they approach the supermarket.
“They feel like they can’t buy one cucumber,” he says. “But I can walk into a shop – I feed two people at home – and I’ll walk into a shop and I buy one cucumber, I’ll buy one onion.”
Mr Payne asks for the sticker to be placed directly on each item, rather than face the temptation of filling one of the two-kilogram capacity plastic bags on offer.
The chef also advises singletons not get too hung up on “organic”, particularly high-priced varieties that have been flown in from far-flung locales. Local produce is often grown sustainably, and far cheaper, he says.

What is graphene?
Graphene is a single layer of carbon atoms arranged like honeycomb.
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.
At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.
It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.
But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.
