Nobel Prize-winning work is flying in space as we speak.
The International Space Station (ISS) is hosting a quantum experiment based on a discovery made by new Nobel laureate Moungi Bawendi, a French-born American/Tunisian chemist.
Bawendi, who won the 2023 Nobel Prize in Chemistry, called the ISS on Monday (Dec. 11) alongside fellow physics Nobel laureate Ferenc Krausz. Bawendi told students beforehand that science is a process of experiments that create unpredictable and yet interesting results.
"Everything you discover is a little bit new," he said. "You might have an idea of what you expect to find. But it's always going to be somewhat different. Sometimes it's very different, but it's always an adventure."

Bawendi won the Nobel Prize for his applications of quantum dots, which are semiconductor nanocrystals. Most Samsung televisions today use quantum dots, based on a gallium nitride diode invented in the late 1990s. "The quantum dots absorb some of that blue light and reimage as green and red," he explained.
Now similar tech is being tested outside the ISS for stability in space, which got Bawendi's attemtion during the livestreamed call with commander Andreas Mogensen, an astronaut with the European Space Agency. "Do you like, baby them or feed them? What do you do with them, if anything?"
Today, I will be speaking with two Nobel Prize laureates from 2023, Ferenc Krausz and Moungi Bawendi, who are currently in Stockholm, Sweden.

The ISS experiment is called the Materials International Space Station Experiment-18-NASA (MISSE-18-NASA), which is part of a series of passive payloads mounted outside the ISS using the Japanese Kibo robotic arm.
Mogensen emphasized that the Expedition 70 crew's involvement is getting the experiment properly mounted on the arm for future mounting. "Then it runs more or less autonomously once it's outside," he said.
"Well, we'll see how they behave when they come back to Earth," Bawendi responded. Each "outside" set of experiments is rotated every six months, so we might learn more about this work in 2024 or early 2025 once they are returned to Earth.
Mogensen, who is from Denmark, also showed off a space surprise: it turns out the medal of Danish physicist Niels Bohr is on the ISS with him right now. The 1922 prize for Bohr was based on his work examining the atom, a fundamental unit of particle physics. The medal is on loan from the Museum of National History in Denmark, according to a post Mogensen made on X (formerly Twitter).
Mogensen did not explain upon which ship the Nobel flew to orbit, but ESA materials said he "brought (the medal) with him", suggesting it flew on board SpaceX Crew Dragon. As Mogensen carefully worked to hold the medal up before the camera, Mogensen joked he had to be careful that items "do not fly away" from him in weightlessness.
Bohr once donated his Nobel Prize medal to a 1940 U.S.-backed effort to raise funds for Finland during the 1939-1940 Winter War, following the internationally condemned invasion of Finland by the Soviet Union. Fellow laureate August Krogh donated his as well to that cause. An anonymous buyer bought both medals and gave them to the Danish national museum, where the Nobels remain in the permanent collection, according to the Nobel Prize website.
"To me, the Nobel Prize is something very important," Mogensen added. "It's a symbol for humankind's never-ending curiosity, and the desire to explore, and passion to learn. It is also a symbol for not only learning new things, but also communicating that: publishing it, writing about it and talking about it and spreading that knowledge, our threshold of knowledge for humankind."
