It's like car-pooling, but only for the rich and famous who want to show their green credentials. Madonna, the Prince of Wales and 3000 other beautiful people have been invited to join the world's first private flight sharing club. This will allow them to still get around in style but reduce the environmental impact and cost of private jets that are currently flying empty 40% of the time.

The Flightshare Private Members Guild is the brainchild of Farnborough UK based David Lacy, an aviation veteran of 26 years who was the first to introduce carbon offsets to the European private jet industry last year.

Skis equipped with an ingenious new self-waxing device that enables them to travel quicker could make a dramatic entry onto the skiing scene in the 2008/09 World Cup season.

The device continuously applies fresh wax to the bottom of the ski during a race. Its developers are now working with manufacturers, with the aim of incorporating it into skis used in top-class international competition as early as next year.

Validated test results from the Alps show that skiers using the revolutionary system can complete a course 1-2% quicker than using conventional skis, which gradually lose their pre-applied layer of wax as they descend a slope.

The sea-ice is getting thinner. Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001. These are the initial results from the latest Alfred-Wegener-Institute for Polar and Marine Research in the Helmholtz Association lead expedition to the North Polar Sea.

50 scientists have been on board the Research ship- Polarstern for two and a half months, their main aim; to carry out research on the sea-ice areas in the central Arctic. Amongst other things, they have found out that not only the ocean currents are changing, but community structures in the Arctic are also altering.

The washing machine and the refrigerator are going to start "talking" to the television thanks to a new standard about to be published by the Geneva-based IEC. This new ability to network traditional household appliances with personal computers and audio-visual equipment will offer such possibilities as your television screen displaying the fact that the washing machine has finished washing your clothes or turning on an air conditioner from your personal computer.

Computer models now under development could enhance the design of sports equipment to help people of all abilities realise their sporting potential.

The models, more sophisticated and more specialised than others previously used in sports equipment design, produce unprecedentedly realistic simulations of how potential ball designs, for instance, will actually behave when in use.

This data can then be harnessed by sports equipment design teams to ensure that the final products they develop behave (e.g. bounce and spin) as required and, above all, with more consistency than ever before. This is vital if sportsmen and women are to optimise their skills, apply them with confidence and maximise their achievement.

A revolutionary new sensor collects and immediately transmits data about posture, stride length, step frequency, acceleration, response to shock waves travelling through the body etc.

It's cufflink-sized and clipped behind the wearer’s ear, so it doesn't hinder performance and when worn by an athlete during training, it can transmit the information for immediate visual display on a handheld device or laptop used by their coach at the trackside. The coach can then harness the data to shape the on-the-spot advice and instruction they give the athlete regarding technique. By instantly adding to the value of every training session, the sensor can therefore deliver better sporting performance.
