Meet Xenobot, an Eerie New Kind of Programmable Organism

Posted by in categories: bioengineering, information science

Under the watchful eye of a microscope, busy little blobs scoot around in a field of liquid—moving forward, turning around, sometimes spinning in circles. Drop cellular debris onto the plain and the blobs will herd them into piles. Flick any blob onto its back and it’ll lie there like a flipped-over turtle.

Their behavior is reminiscent of a microscopic flatworm in pursuit of its prey, or even a tiny animal called a water bear—a creature complex enough in its bodily makeup to manage sophisticated behaviors. The resemblance is an illusion: These blobs consist of only two things, skin cells and heart cells from frogs.

Writing today in the Proceedings of the National Academy of Sciences, researchers describe how they’ve engineered so-calleds (from the species of frog, Xenopus laevis, whence their cells came) with the help of evolutionary algorithms. They hope that this new kind of organism—contracting cells and passive cells stuck together—and its eerily advanced behavior can help scientists unlock the mysteries of cellular communication.

Is a home coronavirus test on its way?

Posted by in category: biotech/medical

Hod Hasharon-based BATM Advanced Communications Limited announced that they have developed a new diagnostic kit to detect the novel coronavirus.

As the CEO of the company Dr. Zvi Marom explained to The Jerusalem Post, compared to the kit that is currently used by hospitals all over the world, the product conceived by BATM has the advantage of being faster and more accurate and, within a few weeks, the company aims to set the cost at approximately NIS 1 per test. The kit is expected to be CE approved next week.

NASA issues a Venus rover design challenge

There’ve been missions to Venus over the past decades, but Venus is a tough place to visit, with temperatures on its surface hot enough to melt lead. The last probe that landed on Venus’ hellish surface was part of the Vega 2 mission in 1985; it transmitted data from Venus’ surface for 57 minutes. Now NASA wants to visit Venus’ surface again, not with just another lander … but with a rover.

On February 21, 2020, NASA announced a public challenge to help design a future Venus rover called Automaton Rover for Extreme Environments (AREE). The challenge – Exploring Hell: Avoiding Obstacles on a Clockwork Rover – is specifically to develop an obstacle-avoidance sensor for the rover. The concept is being funded by a grant from the NASA Innovative Advanced Concepts program.

SpaceX to Launch NASA’s Psyche Mission to Metal Asteroid

Posted by in categories: asteroid/comet impacts, existential risks, space travel

NASA has contracted SpaceX to carry out the launch for its upcoming Psyche mission to a strange metal asteroid in our solar system. The launch will use one of SpaceX’s Falcon Heavy rockets, for a cost of $117 million.

“The Psyche mission will journey to a unique metal-rich asteroid, also named Psyche, which orbits the Sun between Mars and Jupiter,” NASA explained in a statement. “The asteroid is considered unique, as it appears to largely be made of the exposed nickel-iron core of an early planet — one of the building blocks of our solar system.” Astronomers believe that studying this unusual asteroid could help us to understand how planets develop, including planets like Earth.

“Deep within rocky, terrestrial planets, including Earth, scientists infer the presence of metallic cores, but these lie unreachably far below the planet’s rocky mantles and crusts,” NASA said. “Because we cannot see or measure Earth’s core directly, the mission to Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets.”

Boeing Defense, Space and Security offers $30,000 bonuses for satellite engineers

Posted by in categories: satellites, security

Boeing is offering signing bonuses up to $30,000 for experienced satellite engineers and procurement specialists, saying Friday needs the staff “to help build assets for the U.S. Air Force and its allies.”

The company posted a notice about its hiring on LinkedIn, listing more than open 75 jobs for what Boeing said were its “rapidly growing” satellite program efforts.

“We have an urgent need for Security Cleared Satellite Engineers to help build assets for the U.S. Air Force and its Allies. We’re offering a potential $30k sign-on bonus,” the posting said.
