Cheap trainers still protect feet
Expensive trainers do not protect runners' feet more than cheaper ones, according to a study published in the British Journal of Sports Medicine.

Dundee University researchers asked participants to test three pairs - costing £40 to £45, £60 to £65, and £70 to £75 - made by different brands.

Electronic tests on eight areas of the sole as they walked and ran found no major differences in cushioning impact.

Impact was sometimes cushioned better in cheaper trainers, the study found.

That findings were reached after injury-causing...

Pas fantastique, le plastique

Deglise, Fabien

Pour changer les comportements de l'industrie de la consommation, doit-on se fier à l'éducation des consommateurs et aux pressions qui pourraient normalement venir avec? Ou bien imposer des lois pour forcer la main des dirigeants d'entreprise?

Devant ce dilemme, la petite ville de Leaf Rapids, au Manitoba, vient de trancher. Dans un geste étonnant, au début du mois, la municipalité de 500 âmes...

Le TGV fracasse son record de vitesse

Le, Devoir

Le TGV a établi hier, à 574,8 km/h, un nouveau record du monde de vitesse sur rail, sur la ligne à grande vitesse est-européenne.

D'une puissance deux fois supérieure à celle d'un TGV normal, spécialement construite par Alstom et dénommée V150, la rame a pulvérisé le record de 515,3 km/h établi le 18 mai 1990 par un TGV Atlantique entre Paris et Tours. Lors des essais menés...

Blu-ray player put to the test
By Darren Waters
Technology editor, BBC News website

High definition movies have finally arrived in the UK in the shape of the first Blu-ray player from Samsung, the BD-P1000.

For more than two years we have been tantalised with promises of knockout picture quality that would make ordinary DVD video look tired and monochromatic. But does the reality match the hype?

Samsung's first UK Blu-ray player is a sleek unit that outwardly resembles an ordinary DVD player.
