Saudi Scientists From KAUST Find New Way To Store CO2
The new method for storing and transporting carbon dioxide in solid form could have a huge impact in fighting climate change.
Scientists from Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) have discovered a novel way to store and transport CO2 in the form of a powder.
The breakthrough discovery was made by a team of scientists led by Professor Cafer T. Yavuz of KAUST. The researchers created a mesh-like clathrate structure, which can physically trap molecules of one component within the crystal structure of another.
This clathrate structure proved to be a more energy-efficient way to trap and store greenhouse gasses, as it requires no refrigeration, making it much more energy efficient than current systems.

“Our team made it possible to carry CO2 in a solid form without the need for refrigeration or pressure. You will be able to literally shovel CO2-loaded solids from now on,” explained Professor Yavuz. “The impact is wide and strong, as the global fuel industry and the kingdom entities are actively looking for ways to capture, store and transport CO2 without significant energy penalties”.

Instagram Now Lets You Tune Its Algorithm, But There’s One Big Catch
The new controls promise users “agency” over their feed, but asking to see more from accounts you actually follow returns an error.
Instagram has expanded its algorithm personalization feature to the main feed, letting users specify which topics they want surfaced more or less often in recommendations.
Instagram chief Adam Mosseri framed the change as a matter of user control. “I believe it’s in our best interest as a business to empower people to shape Instagram into something that works for them, and that people should be able to have a meaningful amount of agency over the products they spend so much time in,” he wrote on Threads.
Though it turns out that agency has limits. The controls only accept interest-based topics, such as “rescue dogs” or “parenting humor”. Requesting “posts from people I follow” returns no results, which is obviously a sore point for creators whose posts rarely reach their own audiences. Mosseri conceded the tension: “Who you follow used to be a meaningful tool people had for shaping their own experience, and as recommendations took over the main feed that tool quietly stopped working”.

Instagram credits large language models for making its algorithms legible enough to personalize, and says it is “actively working on supporting requests for people, different moods or vibes, content types, and more” – potentially leading to a fully “bespoke” version of the app.
