It's not too late to pick up a few more items for the... shall we say... more difficult members of the family. Christmas-present-wise, is what we're saying. Our extensive gift guide tells you what to get the tech-mad futurist in your life.

We also check the status of the military's possibly insane hypersonic aircraft program, cook up a pill to cure heartbreak, go cruising in a hot-tub convertible, and think seriously about eating bugs.

All inside the mag, on sale now. In shops!
