Last week, I started a discussion of what I call "The Three Origins," focusing first on the origin of life. Although we are far from knowing how non-living matter became living organisms on primitive Earth some 3.5 billion years ago (or more), or how to repeat the feat in the laboratory, I consider this the "easiest" of the three questions.

China is once again at odds with a maritime neighbor over disputed islands, this time — as often — leading to a little shooting and a lot of posturing.
The latest confrontation is with Vietnam over the mostly uninhabited Paracel Islands in the South China Sea. Hanoi has accused Beijing's forces of firing on a Vietnamese vessel engaged in fishing near the islands, which both sides claim.
Vietnam did not say if anyone was hurt in the incident that occurred last Wednesday, but it described the matter as "very serious."

You step down from the all-terrain camper and out into the bright sunlight. Your boots crunch on the cold desert soil. It's been three solid months in the office with just Sundays off (at best). But now, finally, you are out in the open once again. Above you the sky is its usual brown-hued butterscotch color. Ahead of you is the trail leading to the canyon. The plan is to spend the day walking a trail at the edge of Coprates Chasma, a canyon almost a thousand kilometers long (more than twice the length of the Grand Canyon, they say).
