18400 | New ultrathin materials can pull climate-warming CO2 from the air
MXenes are the largest group of flat, sheetlike nanomaterials. Scientists refer to them as being largely two-dimensional, or 2-D. Another famous example of a 2-D material is graphene.
This diagram depicts a process to convert MAX phase materials into thin sheets of MXenes. An acid etches out all but the M layers (blue) and X layers (purple) to yield thick MXene sheets. The far right panel shows a scanning electron microscope image of the MXene. M. Ozkan et al/Chem. Oct. 4, 2023 ( CC BY 4.0 DEED
MXenes have “probably the largest diversity and tunability any 2-D material can offer,” says Michael Naguib. By tunable, this engineering physicist means that MXenes can be tweaked to take on different properties. Naguib works at Tulane University in New Orleans, La. |

Then the MXenes could be reused for a new round of carbon capture.
MXenes could also help transform the CO 2 they capture into other useful compounds, Stavila says. That’s because MXenes are catalytic. That means they can help drive other chemicals, such as CO 2 , to react. MXenes also conduct electricity. Since they like sharing electrons with CO 2 , they can ferry those electrons to other compounds.
As a result, “you can do [transformations of CO 2 ] that may not be otherwise possible,” Stavila says. For instance, with a boost from MXenes, CO 2 can react with hydrogen to form methanol or formic acid. These liquids can be used as fuels to reduce people’s reliance on newly mined fossil fuels, which add new CO 2 to the atmosphere. Or, better yet, these liquids can be stored somewhere to keep their carbon out of the air for good. |

18466 | Deepfake election risks trigger EU call for more generative AI safeguards
The European Union has warned more needs to be done to address the risks that widely accessible generative AI tools may pose to free and fair debate in democratic societies, with the bloc’s values and transparency commissioner highlighting AI-generated disinformation as a potential threat to elections ahead of the pan-EU vote to choose a new European Parliament next year.
Giving an update on the the bloc’s voluntary Code of Practice on Disinformation in a speech today, Vera Jourova welcomed initial efforts by a number of mainstream platforms to address the AI risks by implementing safeguards to inform users about the “synthetic origin of content posted online”, as she put it. But said more must be done.
“These efforts need to continue and intensify considering the high potential of such realistic AI products for creating and disseminating disinformation. The risks are particularly high in the context of elections,” she warned. |

Giving an update on the the bloc’s voluntary Code of Practice on Disinformation in a speech today, Vera Jourova welcomed initial efforts by a number of mainstream platforms to address the AI risks by implementing safeguards to inform users about the “synthetic origin of content posted online”, as she put it. But said more must be done.
“These efforts need to continue and intensify considering the high potential of such realistic AI products for creating and disseminating disinformation. The risks are particularly high in the context of elections,” she warned. “I therefore urge platforms to be vigilant and provide efficient safeguards for this in the context of elections.”
The EU commissioner noted she’s meeting representatives of ChatGPT maker, OpenAI, later today to discuss the issue.
The AI giant is not a signatory to the bloc’s anti-disinformation Code — as yet — so is likely to be facing pressure to get on board with the effort. (We’ve reached out to OpenAI with questions about its meeting with the Jourova.) |

The commissioner’s remarks today on generative AI follow initial pressure applied to platforms this summer, when she urged signatories to label deepfakes and other AI-generated content — calling on Code signatories to create a dedicated and separate track to tackle “AI production”, and quipping that machines should not have free speech. |
