To create a synthetic memory, DDS uses open-source image-generating AI systems such as DALL-E 2 and Flux, while the team is developing its own tool.

That’s how the team found traces of either dimethyl sulfide (DMS) or dimethyl disulfide (DMDS) – or both – in the atmosphere of K2-18b.On Earth, these compounds are only produced by living beings, particularly microbes such as marine phytoplankton. What’s more, what the scientists found suggests that the concentration of these chemicals in the K2-18b atmosphere was thousands of times higher than on Earth.

“It was an incredible realisation seeing the results emerge and remain consistent throughout the extensive independent analyses and robustness tests,” said co-author Mans Holmberg, a researcher at the Space Telescope Science Institute in Baltimore, United States, in a media statement on the Cambridge University website.How reliable are the findings?The scientists published their findings in the peer-reviewed Astrophysical Journal Letters publication, which means that other experts in the field who studied their paper found it convincing.

But that does not mean that the scientists have found irrefutable evidence of life. Far from it.Madhusudhan acknowledged that it is possible that the traces of DMS and DMDS found in the atmosphere of K2-18b are the outcome of chemical phenomena that are as of now, unknown to humanity.

“It’s important that we’re deeply sceptical of our own results, because it’s only by testing and testing again that we will be able to reach the point where we’re confident in them,” Madhusudhan said. “That’s how science has to work.”

His colleagues in the research team agreed.In Makary’s May 20 article, he and his co-author included pregnancy on the CDC’s 2025 list of underlying medical conditions that increase the risk of severe COVID-19.

“They literally contradicted themselves over the course of a couple of days,” said Dr Peter Hotez, Texas Children’s Hospital Center for Vaccine Development co-director. “It appears RFK Jr reversed his own FDA’s decision.”Following the May 27 video announcement, Makary told NBC that the decision about vaccination should be between a pregnant woman and her doctor.

A 2024 review of 67 studies found that fully vaccinated pregnant women had a 61 percent lower likelihood of a COVID-19 infection during pregnancy.In its June meeting, the Advisory Committee on Immunization Practices might move towards less sweeping recommendations for vaccinating children, closer to those that Kennedy enacted.
