Big Tech’s big bet on a controversial carbon removal tactic
Microsoft, JP MorganChase, and a tech company consortium that includes Alphabet, Meta, Shopify, and Stripe have all recently struck multimillion-dollar deals to pay paper mill owners to capture at least hundreds of thousands of tons of this greenhouse gas by installing carbon scrubbing equipment in their facilities.
The captured carbon dioxide will then be piped down into saline aquifers more than a mile underground, where it should be sequestered permanently.
Big Tech is suddenly betting big on this form of carbon removal, known as bioenergy with carbon capture and storage, or BECCS. But experts have raised a number of concerns. Read the full story.

2025 climate tech companies to watch: Kairos Power and its next-generation nuclear reactors
Like many new nuclear startups, Kairos promises a path to reliable, 24/7 decarbonized power. Unlike most, it already has prototypes under construction and permits for several reactors.
The company uses molten salt to cool its reactions and transfer heat, rather than the high-pressure water that’s used in existing fission reactors. It hopes its technology will enable commercial reactors that are cost-competitive with natural gas plants and boast safer operation than conventional reactors, even in the event of complete power loss. Read the full story.

MIT Technology Review Narrated: Inside the strange limbo facing millions of IVF embryos
Millions of embryos created through IVF sit frozen in time, stored in tanks around the world. The number is only growing thanks to advances in technology, the rising popularity of IVF, and improvements in its success rates.
At a basic level, an embryo is simply a tiny ball of a hundred or so cells. But unlike other types of body tissue, it holds the potential for life. Many argue that this endows embryos with a special moral status, one that requires special protections.
The problem is that no one can really agree on what that status is. While these embryos persist in suspended animation, patients, clinicians, embryologists, and legislators must grapple with the essential question of what we should do with them. What do these embryos mean to us? Who should be responsible for them?

One more thing
Why we should thank pigeons for our AI breakthroughs
People looking for precursors to artificial intelligence often point to science fiction by authors like Isaac Asimov or thought experiments like the Turing test. But an equally important, if surprising and less appreciated, forerunner is American psychologist B.F. Skinner’s research with pigeons in the middle of the 20th century.
Skinner believed that association—learning, through trial and error, to link an action with a punishment or reward—was the building block of every behavior, not just in pigeons but in all living organisms, including human beings.
His “behaviorist” theories fell out of favor with psychologists and animal researchers in the 1960s but were taken up by computer scientists who eventually provided the foundation for many of the artificial-intelligence tools from leading firms like Google and OpenAI. Read the full story.
