For the first time, an international team of researchers has used a quantum computer to create artificial life—a simulation of living organisms that scientists can use to understand life at the level of whole populations all the way down to cellular interactions.

With the quantum computer, individual living organisms represented at a microscopic level with superconducting qubits were made to “mate,” interact with their environment, and “die” to model some of the major factors that influence evolution.

The new research, published in Scientific Reports on Thursday, is a breakthrough that may eventually help answer the question of whether the origin of life can be explained by quantum mechanics, a theory of physics that describes the universe in terms of the interactions between subatomic particles.

Does Chinese commercial space rival government? A story has gone viral in China about the departure of a rocket scientist named Zhang Xiaoping from his job as deputy director of rocket design at the state-owned Xi’an Aerospace Propulsion Research Institute. He was rumored to be helping lead the design of China’s heavy Long March 9 rocket. According to the South China Morning Post, a document posted on a Chinese social media site described how Zhang was “most crucial to the development process,” and had “irreplaceable” talents. The document argued that Zhang’s departure could affect China’s race to send people to the Moon.

Gone to LandSpace … Zhang is rumored to have taken a research position at the private aerospace firm LandSpace (cited above), earning 10 times his previous salary of 120,000 yuan (US$17,400) per year. This is an interesting development, although we have few hard facts from our Western vantage point. However, the Zhang kerfuffle does suggest that some of the same tensions we’re seeing between public and private space in the United States also exist in China with its emerging commercial space market.

Our smartphones are cold, passive devices that usually can’t move autonomously unless they’re falling onto our faces while we’re looking at them in bed. A research team in France is exploring ways to change that by giving our smartphones the ability to interact with us more (via New Scientist). MobiLimb is a robotic finger attachment that plugs in through a smartphone’s Micro USB port, moves using five servo motors, and is powered by an Arduino microcontroller. It can tap the user’s hand in response to phone notifications, be used as a joystick controller, or, with the addition of a little fuzzy sheath accessory, it can turn into a cat tail.

Blue Origin signed a letter of intent with two German space companies to deliver supplies to the Moon by 2023.

There, engineers are doing something strange. They’re freezing computer chips to 460 degrees Fahrenheit below zero, colder than deep space, to simulate the quantum structure of the universe.

At such extreme temperatures these remarkable chips, called qubits, enable scientists to peer into the complex, uncertain interaction of particles at the atomic level — an unseen world in which seemingly contradictory results can exist simultaneously, a place where simply observing an interaction can change it. Or wreck it altogether.

“Quantum — it’s something weird,” said Mike Mayberry, Intel’s chief technology officer and general manager of Intel Labs.

Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much effort, none of the new particles proposed to explain dark matter have been discovered. In a review that was published in Nature this week, physicists Gianfranco Bertone (UvA) and Tim Tait (UvA and UC Irvine) argue that the time has come to broaden and diversify the experimental effort, and to incorporate astronomical surveys and gravitational wave observations in the quest for the nature of dark matter.

Over the past three decades, the search for dark matter has focused mostly on a class of particle candidates known as weakly interacting massive particles (or WIMPs). WIMPs appeared for a long time as a perfect dark matter candidate as they would be produced in the right amount in the early universe to explain dark matter, while at the same time they might alleviate some of the most fundamental problems in the physics of elementary particles, such as the large discrepancy between the energy scale of weak interactions and that of gravitational interactions.

Before the MASCOT lander spent 17 hours studying the asteroid Ryugu, the spacecraft captured some incredible photographs.
