A sample of ancient oxygen, teased out of a 1.4 billion-year-old evaporative lake deposit in Ontario, provides fresh evidence of what the Earth’s atmosphere and biosphere were like during the interval leading up to the emergence of animal life.

The findings, published in the journal Nature, represent the oldest measurement of atmospheric oxygen isotopes by nearly a billion years. The results support previous research suggesting that oxygen levels in the air during this time in Earth history were a tiny fraction of what they are today due to a much less productive biosphere.

“It has been suggested for many decades now that the composition of the atmosphere has significantly varied through time,” says Peter Crockford, who led the study as a Ph.D. student at McGill University. “We provide unambiguous evidence that it was indeed much different 1.4 billion years ago.”

Update July 18th, 11:35AM ET: Blue Origin pulled off another successful test launch today, landing both the New Shepard rocket and capsule after flight. The company ignited the capsule’s emergency motor after it had separated from the rocket, pushing the spacecraft up to a top altitude of around 74 miles — a new record for Blue Origin. The firing also caused the capsule to sustain up to 10 Gs during the test, but Blue Origin host Ariane Cornell said “that is well within what humans can take, especially for such a short spurt of time.”

This morning, Jeff Bezos’ aerospace company Blue Origin will attempt the ninth test flight of its sub-orbital rocket, the New Shepard — a reusable vehicle designed to take tourists to the edge of space and back. And for this launch, the company will be testing out the vehicle’s escape motor once again. That’s the system that could help save the lives of future passengers if something were to go wrong during the climb through Earth’s atmosphere.

Like most vertical rockets, the New Shepard is designed to take off upright from a launchpad at Blue Origin’s facilities in West Texas. Perched on top of the vehicle is a capsule for crew members, which the rocket carries skyward during flight. Once the New Shepard reaches an altitude of around 62 miles — what’s often considered the edge of space — the capsule and rocket separate. If passengers were on board, that’s when they would experience a few minutes of weightlessness. Then, both the capsule and rocket fall back to Earth. Parachutes deploy to gently land the capsule, while the rocket reignites its engine to land upright on the ground.

The mysterious, massively funded mixed-reality company still won’t divulge exactly when the device will be available, but it’s more specific than its previous statement that it would be out sometime this year.

The announcement: While much of the world was paying attention to the World Cup on Wednesday, Magic Leap’s Alan Noon said during a live stream on Twitch that the Magic Leap One, a developer-geared headset, will ship this season. Summer ends September 22, so the company has roughly 10 weeks to meet that deadline.

Also: AT&T said Wednesday that it will be the sole wireless carrier for the headset, bringing it to AT&T stores in cities including San Francisco, Boston, and Los Angeles.

Lagos — With its colourful hammocks and table tennis table, a new tech hub in the Lagos metropolis wouldn’t look out of place among the start-ups on the other side of the world in Silicon Valley.

But the NG_Hub office is in the suburb of Yaba — the heart of Nigeria’s burgeoning tech scene that is attracting interest from global giants keen to tap into an emerging market of young, connected Africans.

In May, both Google and Facebook launched initiatives nearby.
