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.

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.

Scientists who “accidentally” made the first ever recording of a dying brain saw startling results.
Scientists — who “accidentally” made the first ever recording of a dying brain — saw startling results.
Stephen Taylor, assistant professor of physics and astronomy and former astronomer at NASA’s Jet Propulsion Laboratory (JPL), said, “Using the pulsars we observe across the Milky Way galaxy, we are trying to be like a spider sitting in stillness in the middle of her web. How well we understand the solar system barycenter is critical as we attempt to sense even the smallest tingle to the web. The solar system barycenter, its center of gravity, is the location where the masses of all planets, moons, and asteroids balance out.”
So, where is the center of the solar system?
It is not in the center of the Sun as many might assume, instead it is closer to the surface of the star. This is due to Jupiter’s mass and our imperfect knowledge of its orbit.
A 55-year-old man who lost half of his external ear in a work accident in a carpentry shop that couldn’t be reattached nevertheless has a new ear lobe instead.
Plastic surgeons at Jerusalem’s Shaare Zedek Medical Center (SZMC) used advanced technology and artificial cartilage to sculpt a new earlobe and implant it on the side of the accident victim’s head.
The patient was rushed to SZMC’s emergency department after a wooden surface fell on him and caused the loss of the upp… See more.
