Venera-8 made a photo of Venus’ surface possible.
Launched in March 1972, Venera-8 was part of the Soviet Union’s exploration of Venus — in less than an hour it revealed critical details of this seemingly inaccessible planet.
Elliot Ackerman is following the crisis in Ukraine closely. The author and former U.S. marine served five tours of duty in Iraq and Afghanistan and has just spent two weeks in Kyiv. Ackerman joins Walter Isaacson to discuss Russia’s new tactics and the role of moral resolve in war.

Move aside CCDs. Consumer CMOS cameras are here to stay.
For 20 years, I have been using charge-coupled device (CCD) cameras, and I currently own the top-of-the-line SBIG STX-16803. But while studying two images I recently made using the latest QHY 410C CMOS camera, I had to wonder: Is CCD dead?
For years, I lectured about the asymptotic boundary of noise in CCD images. In a basic sense, this means that no matter how many frames you take to increase your signal-to-noise ratio for a cleaner image, you will always run into a wall of noise when you stretch your image to bring out deep shadows. But with QHY’s new CMOS camera, this troublesome wall of noise is nonexistent.
The QHY 410C is a one-shot color camera that utilizes the back-illuminated Sony IMX410 CMOS chip found in high-end cameras like the Nikon Z6 and the Sony A7 III. But the 410C has taken the full-frame (35 millimeter) 24-megapixel chip and mounted it in a camera with regulated cooling and zero amplifier glow, helping drive the noise to such a low level.
Some diabetes therapies work by ramping up the body’s secretion of insulin to counteract high blood sugar levels. | Preserving insulin-producing pancreatic beta cells—rather than exhausting them—might be a better strategy in the treatment of diabetes. Following that thinking, scientists at the Karolinska Institute found a cancer drug by Seagen holds promise for the metabolic disease.
AN EXPERIMENT that could pave the way for the growth of artificial steaks in space to feed future astronauts is to launch next week on the first mission to carry an all-private crew up to the International Space Station (ISS).

►Is faster-than-light (FTL) travel possible? In most discussions of this, we get hung up on the physics of particular ideas, such as wormholes or warp drives. But today, we take a more zoomed out approach that addresses all FTL propulsion — as well as FTL messaging. Because it turns out that they all allow for time travel. Join us today as we explore why this is so and the profound consequences that ensue. Special thanks to Prof Matt.
