next step - just in time for our workshop ... maybe for >Tobias to read before ...

interesting .... have they so far been involved?

Scientists have entered a new path for regenerative medicine by altering age-worn cells in people over 90 into rejuvenated stem cells.

"Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind."

Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire. But recently scientists have begun to realize that some of these little particles are alive - they are bacteria evolved to create ice or water droplets around themselves. old but might be worth a discussion

Scientists have used the National Science Foundation's Very Long Baseline Array (VLBA) radio-telescope system and NASA's Cassini spacecraft to measure the position of Saturn and its family of moons to within about a mile -- at a range of nearly a billion miles.

Droplets can be made to chase each other around a track and even self-assemble into devices, simply by mixing two everyday liquids. This remarkable discovery made by scientists in the US has already been used to create beautiful shapes and patterns, and could also be exploited to create optical components that assemble themselves and even to clean surfaces. It looks very like Jojo's self-assembling balls :p

Technology/Robotics Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away.

Although it may seem like the above two experiments violate the uncertainty principle because the results show a smaller-than-required degree of uncertainty, Shih and his coauthors explain that no violation has occurred due to the fact that the experiments involve photon pairs rather than individual photons. The scientists argue that Popper's original thought experiment was based on a misunderstanding of the proper context of the uncertainty principle: it governs the behavior of single particles only, not the "correlation" of two particles.

Soft Robots Scientists from Cornell University and the Italian Technology Institute in Pontedera have developed an elastic robotic skin that is able to stretch up to five times its size, change colors, and even detect pressure. The luminescent skin, partly funded by the Army and Air Force's research wings, is comprised of different kinds of specialized silicone, making it flexible and soft.

It is an old one, but it was mentioned in some discussion ... Mainly based on this paper https://arxiv.org/abs/astro-ph/0102126

There goes your moon base...

Cameras sure have evolved these days...

On the topic of asteroid composition :)
