Here's your afternoon TNB Tech Minute for Wednesday. August 6th, I'm Julie Chang for the Wall

Street Journal. The Federal Trade Commission is moving to block Edward Life Sciences' proposed acquisition

of medical device company Yennavalve Technology. In a complaint filed today, the agency said

the acquisition would limit competition in the aortic

regurgitation device market. Both companies said they disagree with the FTC's decision.

In earnings, Airbnb logged higher sales and earnings in the second quarter as travel demand

picked back up. The vacation rental platform posted a profit of $642 million,

above analyst expectations. Meanwhile, Lyft's profit also rose last quarter as ridership and

bookings grew. The ride-sharing app posted a profit of $40.3 million. Revenue increased 11% to $1.59 billion, narrowly missing expectations.

And DoorDash also exceeded Wall Street forecasts. The food delivery app swung to a profit of $285 million

compared with a loss last year. Second quarter revenue jumped to $3.28 billion. Finally, in recent months,

North Korea has sped up construction of a launch site to be used for spy satellites. Security experts

say the site includes the addition of a seaport that could be used to get deliveries from Russia,

such as larger rocket

components. North Korea hasn't commented publicly on the recent site expansion. And that's a wrap

for your TNB Tech minutes today. Tune in tomorrow morning for your next quick tech update.
