Dmitry Rogozin, the head of Russian space agency Roscosmos, issued a stark warning.
The future of the ISS has come into question amid conflict in Ukraine. Dmitry Rogozin, the head of Roscosmos, has warned that blocking cooperation could have catastrophic consequences.
Nature is a never-ending source of inspiration for scientists, but our artificial devices usually don’t communicate well with the real thing. Now, researchers at Linköping University have created artificial organic neurons and synapses that can integrate with natural biological systems, and demonstrated this by making a Venus flytrap close on demand.
The new artificial neurons build on the team’s earlier versions, which were organic electrochemical circuits printed onto thin plastic film. Since they’re made out of polymers that can conduct either positive or negative ions, these circuits form the basis of transistors. In the new study, the team optimized these transistors and used them to build artificial neurons and synapses, and connect them to biological systems.
When the transistors detect concentrations of ions with certain charges, they switch, producing a signal that can then be picked up by other neurons. Importantly, biological neurons operate on these same ion signals, meaning artificial and natural nerve cells can be connected.
Roscosmos’s head warns the ISS mission could end with a destructive deorbit in a threat to the US, EU and other countries.
WASHINGTON — The European Space Agency will establish a committee with representatives from both inside and outside the space industry to develop options for a European human space exploration program.
The creation of what ESA called a “high-level advisory group” was one of the major outcomes of a one-day “space summit” held in Toulouse, France, Feb. 16 that brought together representatives of member states of both ESA and the European Union to discuss future European space initiatives.
Josef Aschbacher, director general of ESA, said the proposal for the advisory group came from French President Emmanuel Macron. “We got a very clear message from President Macron that such a group is needed. He has asked ESA to put the group together,” he said at a press conference at the end of the summit.
The Webb team continues to make progress in aligning the observatory’s mirrors. Engineers have completed the first stage in this process, called “Segment Image Identification.” The resulting image shows that the team has moved each of Webb’s 18 primary mirror segments to bring 18 unfocused copies of a single star into a planned hexagonal formation.
Astronauts representing countries in direct armed conflict have never worked on the space station. Right now, the International Space Station crew consists of U.S. astronauts Raja Chari, Mark Vande Hei, Thomas Marshburn and Kayla Barron; Matthias Maurer, a German from the European Space Agency; and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov.
Economic sanctions may affect the space programs on Earth, Mastracchio says, but the space-station crews never saw the impact of anything. “The programs themselves still get along,” he says. “It was really just, we were friends before we went up to space, and you’re working up there relying on each other and you continue to do that.” Chamitoff says he wishes the world would take more notice of cooperative operations in space, which could be a better model for how to do things geopolitically. “The space station has been an amazing project that’s brought 15 countries together for 30 years,” he says. “When things like this happen and there’s these kind of tensions, you kind of wonder, ‘Does anybody notice that we’re working together and it’s going great?’”

🚨 A major breakthrough.
Scientists have successfully implanted an artificial neuron into a Venus Flytrap, in what could be a major breakthrough in the merging of living things and computers.
The neuron was able to control the plant, making its lobes close, the scientists report.
Chinese rover Yutu-2 has discovered mysterious glass spheres on the far side of the moon. The paper detailing the discovery has been published in Science Bulletin.
“Collectively, the peculiar morphology, geometry, and local context of the glass globules are consistent with being anorthositic impact glasses,” the researchers write in their paper.

Imagine a field of wheat that extends to the horizon, being grown for flour that will be made into bread to feed cities’ worth of people. Imagine that all authority for tilling, planting, fertilizing, monitoring and harvesting this field has been delegated to artificial intelligence: algorithms that control drip-irrigation systems, self-driving tractors and combine harvesters, clever enough to respond to the weather and the exact needs of the crop. Then imagine a hacker messes things up.
