Australian researchers claim to have found 500,000 cubic kilometres (120,000 cubic miles) of water buried beneath the seabed on continental shelves off Australia, China, North America and South Africa. The discovery comes as United Nations estimates suggest water use has been growing at more than twice the rate of the population of the world over the last century. ...read

The house was designed by Singapore-based architect Myitr Malcew for H2ORIZON, a French developer that specialists in floating structures. Built on a buoyant platform, it boasts two bedrooms, two bathrooms and a kitchen.
1.34-million-year-old human ancestor had 'massive' arm bones for climbing trees
The discovery was made by analysing the bones of a Paranthropus boisei hominid which were found at the Olduvai Gorge World Heritage fossil site in Tanzania. Researchers believe the creature stood 3.5 to 4.5 feet tall, was very strong and had a robust frame. The size of the arm bones shown in the main image suggests strong forearms and a powerful upper body. The inset image shows the skull of the creature first evolved in East Africa about 2.3 million years ago.
The trainers that TEACH you how to run: Sensors inside hi-tech 'smart shoes' improve jogging style and prevent injury
Scientists from the Fraunhofer Institute for Photonic Microsystems (IPMS), Germany, developed the smart shoe to combat risks of ankle damage when running. They developed a hi-tech running shoe with ‘Runsafer’ sensors in the sole, which measure the biomechanical data of the athlete and evaluate the runner's form with the help of measurements in real time.

The 'Uniquely Useful Tool' claims to be the first crowd-sourced multi tool as the public has chosen the components to be included. The company claims it reflects a more improvisational approach to DIY in the 21st Century.

Saturn's storm in action: Scientists create incredible animations of hexagonal tempest using photos taken by the Cassini probe
The footage captured by Cassini (inset) reveals the storm around Saturn's north pole, as well as small vortices rotating in the opposite direction of the hexagon. Some of the vortices are swept along with the jet stream as if on a racetrack. The largest of these vortices spans about 2,200 miles (3,500 km), or about twice the size of the largest hurricane recorded on Earth. ‘A hurricane on Earth typically lasts a week, but this has been here for decades -- and who knows -- maybe centuries,’ said Andrew Ingersoll, at the California Institute of Technology in Pasadena.
The stomach-churning Christmas dinner for GAMERS: Tin containing a three-course meal means no time is wasted in the kitchen
The £1.99 Christmas Tinner from UK retailer Game is made up of nine layers of traditional festive food including a scrambled egg starter, a turkey dinner with all the trimmings, finished off with a layer of Christmas pudding. It even comes with mince pies. The 400g tin takes 12 minutes to cook and the chemical reaction used to heat the food inside the can means users don't even need to use a cooker or microwave.
Playful orangutans take GoPro cameras into the Sumatran rainforest as they film themselves taking part in 'jungle training'
EXCLUSIVE: The orangutans made the most of device, pulling faces into the lens and taking it into the trees of Indonesia’s Bukit Tigapuluh National Park. ‘As all the orangutans in our programme are orphans and hand raised by humans they were very relaxed having a GoPro team around,’ said Dr Peter Pratje of Frankfurt Zoological Society and project manager in Indonesia. The project trains orphaned orangutans with the skills they need to survive in the wild. Experts estimate orangutans could be extinct in the wild in less than 25 years.
GADGET REVIEWS
SMARTPHONES? IT'S YOUR CALL
The ultimate non-iPhone smartphone guide...
Talk time: 9.5hr (7hr playback, 55hr music)
Spec: 3.7in (800x480 pixels) AMOLED screen, 16GB, 1.4GHz Windows Mango, 8MP camera, 720p HD video
Verdict: This combination works wonderfully. It's a pleasure to use and Nokia's Drive GPS app is impressive. We've rated these iPhone alternatives from Ace down to Five - and the Nokia is at the head of the pack.
Talk time: 8.5hr
Spec: Android Ice Cream Sandwich OS, 1.2GHz dual-core processor, 4.65in (720x1,280) AMOLED screen, 5MP camera, 1080p video, 16GB memory
Verdict: It's got a beautiful screen, intuitive operating system and cool features like face-recognition security, but battery life doesn't quite match the hype.
Talk time: 6hr 50min
Spec: Windows Phone 7.5 Mango, 1.5GHz, 4.7in (480x800) screen, 16GB, 8MP camera, 720p HD video
Verdict: The Titan is slim, light and has the largest screen on any Windows device. Shame they didn't give it better screen resolution.
Talk time: 4hr
Spec: Android 2.3 Gingerbread, 1 GHz, 4.3in (800x480) screen, 8MP camera, 1080p HD video, 8GB memory
Verdict: The sharp lines and thin bezel give a professional look while the monochrome interface screams class. One for the fashionistas.
Talk time: 5hr 20min
Spec: BlackBerry 7 OS, 1 GHz, 2.45in (480x360) screen, 5MP camera, VGA video, 8GB memory
Verdict: Beautifully made and with a battery life most handsets would kill for, but the OS is limiting and even with its touch screen it can't compete.
Talk time: 7hr 35min
Spec: Android 2.3.4 Gingerbread, 1.4GHz, 4.2in (854x480) screen, 1GB internal, 8GB MicroSD memory (included), 8.1MP camera, 720p HD video
Verdict: Motorola take note, this is how you do slim and sexy. The camera is let down by a poor menu and awful shutter button, but Sony's social media widget 'Timescale' is a time-saving stroke of genius.
Talk time: 10hr
Spec: Android 2.3.5 Gingerbread, dual-core 1.2 GHz processor, 4.3in Super AMOLED (540x960) screen, 8MP camera, Full HD video, 16GB
Verdict: Light and impossibly thin, but even with its rigid Kevlar frame it feels limp and lopsided in the hand. Shame, as the screen is exceptional and the interface is bursting with neat tricks including the ability to resize the icons you use most.
Talk time: 4hr 30min
Spec: Android 2.3 Gingerbread, 800MHz processor, 3.5in (800x480) screen, 5MP camera, 512 MB internal memory, 2GB microSD card (included)
Verdict: Never going to induce envy but if you want smartphone functionality without budget busting it's hard to fault. Navigation is intuitive; battery life excellent.
Talk time: 4hr
Spec: Android 2.3 Gingerbread OS, 3.5in (800x480) screen, 5MP camera, 800MHz processor, 512MB memory, 2GB microUSB card, GPS
Verdict: The Vivacity is essentially the San Francisco II with iPhone looks, and while it lacks the fluidity of its more expensive cousins, you can get app-happy on a budget.
Talk time: 4hr 30min
Spec: Android 2.2 Froyo, 2.8in (240x320) screen, 2MP camera, 130MB memory, 2GB microSD card
Verdict: It might be cheap, small and pocketable but as a smartphone it's cramped, slow and the minuscule memory limits the number of apps.
From sunspots to solar eruptions: Amateur astronomer captures incredible images of the sun using basic camera equipment
Amateur astronomer Jose Manteca from Begues, near Barcelona, took the photos from small observatory on the terrace of his house. The 54-year-old says he spends hours on the terrace gazing into space, hoping to spot scintillating solar activity. He has developed a technique to take 15 images per second using a humble DSLR camera and a solar telescope. The images include stunning close-ups of solar prominences, sunspots and even a plane crossing the face of the sun.
The flooring made from SNAIL POO: Artist creates colourful tiles using paper digested by molluscs
Dutch artist Lieske Schreude has been feeding snails with coloured paper (top left) and shaping their vibrant poo into floor tiles (top right). The artist thought of the concept when she noticed a plague of snails in her garden who enjoyed eating paper and cardboard. The designer noticed that snails not only eat coloured paper, but also recycle it in that same colour because their bodies reject the colour pigments. Ms Schreuder said the faeces can also be pressed into a mould using a spatula to create delicate thread five-millimetres thick (bottom left).
