When Chip Yates started working on his electric airplane in 2012, he wasn't trying to make conventional, gas-powered aircraft look slow. That hasn't changed, he says. "That was not the design goal."

But he's happy to point out his plane is as fast or faster than its competitors that run on single piston gas engines. The five world records Yates set last year for electric planes were finally officially verified by the Fédération Aéronautique International (FAI) last week, and now he can officially claim bragging rights.

The news: A game-changing condom that kills almost all sexually transmitted infections, including herpes, HIV and HPV is one step closer to hitting the market. The Australian market, that is.

Ansell, the Australian prophylactic company, will manufacture a condom laced with the antimicrobial VivaGel lubricant. Australia's version of the Food and Drug Administration, the Australian Therapeutic Goods Administration, gave the product a Conformity Assessment Certification, meaning that it could be on the market within months. The gel is proven effective in killing 99.9% of sexually transmitted infections (STIs).

There once were two planets, new to the galaxy and inexperienced in life. Like fraternal twins, they were born at the same time, about four and a half billion years ago, and took roughly the same shape. Both were blistered with volcanoes and etched with watercourses; both circled the same yellow dwarf star—close enough to be warmed by it, but not so close as to be blasted to a cinder. Had an alien astronomer swivelled his telescope toward them in those days, he might have found them equally promising—nurseries in the making. They were large enough to hold their gases close, swaddling themselves in atmosphere; small enough to stay solid, never swelling into gaseous giants. They were "Goldilocks planets," our own astronomers would say: just right for life.
