High Hurdles Daunting But Doable
In the course of writing a feature for this issue on the inroads that quantum cascade lasers are making into the medical arena, I was reminded once again of the many hurdles that new technologies (and devices that employ them) face on the track from bench to bedside. Not only must a technology be proven viable – and viable for targeted applications – but it must also face myriad...

Insulation through imitation
When temperatures drop, we humans do our best Arctic animal impressions: We don the puffiest coats we can find, insulate our homes with thick mineral wool – even migrate. But we aren’t wild animals, and our bodies cannot insulate themselves enough to keep out the chill, so thousands of dollars are spent to heat our homes every winter. Maybe if we imitated the polar bear after actually...
