David Butler designed his safety brakes so they could be easily installed on existing saws and machine tools. This prototype is installed on a Delta 15-inch scroll saw, a model that has been used for decades in schools.
When you think of cutting-edge technology, power tools don't generally come to mind. Take the table saw: Many woodworkers are using 30-year-old saws in their wood shops and, among the major tool companies, there hasn't been much innovation since those decades-old tools came out.
But more and more inventors are trying to make these saws safer — and David Butler is one of them. At his home in Cape Cod, Mass., Butler flips on the fluorescent lights in his basement turned wood shop.

Mothers of new babies might be forgiven for turning to caffeine to get through those sleep-deprived months. And they might worry that drinking coffee interferes with the sleep of breast-fed babies — the Web is full of such questions. But a new study says it's not so.
Instead, researchers in Brazil found that the babies of heavy coffee drinkers were no more likely to wake up than were babies whose moms didn't have a serious espresso habit.
Crying and colic at 3 months old, as well as frequent night waking at 12 months, were not affected by a mom's caffeine intake.
