For women, buying the wrong shoes can be about more than just esthetics.
If they end up with shoes that don't fit properly, they can develop
foot disorders such as bunions, hammertoes or ingrown toenails. That's

Plastic carrier bags are typically petroleum-based, take a long time to decompose and are often imported from distant countries. They're also tricky to carry when cycling. The new PaperJohn tackles all of these issues. It's a backpack made of biodegradable, 100 percent recycled paper.
Israeli electrical engineer Avraham Hagay wrote into Gizmag this week to tell us about his invention, a motorized shopping trolley designed to make it easier to push a full load of groceries around the store and back to your car. The system, which carries loads of up to 120 kg (265 lbs), can be retrofitted onto existing carts or integrated into new builds. Hagay's currently in talks with local companies and he hopes to soon find a business partner to help manufacture, market, and sell the technology worldwide.
When you run out of something at home, it's all too easy to forget to add it to your next shopping list. This prototype device is aimed at ensuring that no longer happens. The GeniCan attaches to a trashcan so it can be used to scan barcodes of items as they are thrown out. They can then be added to a list or automatically reordered.
