Clean energy technologies in the electric power, transportation, industry, and building sectors will drive this change, because the use of fossil fuels in these areas causes three-quarters of global greenhouse-gas emissions. We’ll also need technologies to slash emissions from agriculture and deforestation and to remove carbon dioxide from the atmosphere and store it. Most of these technologies, however, come with what Bill Gates refers to as a high “green premium”—a measurement of the difference in cost between a clean option and a carbon- intensive one. In other words, clean energy technologies often cost more to use.
A 2021 study by Vivid Economics suggests that in a scenario with limited public and private funding for research, development, and commercialization of new technologies, the green premium for several critical technologies would remain too high by the end of this decade. By speeding innovation in this period, on the other hand, we could reduce the annual costs of the transition to net-zero emissions $2.5 trillion per year by 2050. And a cheaper transition is a more palatable one for countries around the world.
So how do you speed innovation? One way is by promising future customer demand. This gives innovators and investors an incentive to scale up unproven technologies and find ways to rapidly cut costs in the process. The First Movers Coalition, launched by President Joe Biden and John Kerry, the US special presidential envoy for climate (and my boss), along with the World Economic Forum, includes over 50 of the world’s largest companies, which have all made commitments to purchase emerging climate technologies by 2030. These include clean fuels to decarbonize shipping and aviation, decarbonized steel and aluminum, zero-emissions trucks, and advanced technologies to suck carbon out of the atmosphere.

How do I know if egg freezing is for me?
The tool is currently being trialed in a group of research volunteers and is not yet widely available. But I’m hoping it represents a move toward more transparency and openness about the real costs and benefits of egg freezing. Yes, it is a remarkable technology that can help people become parents. But it might not be the best option for everyone.

Anna Louie Sussman had her eggs frozen in Italy and Spain because services in New York were too expensive. Luckily, there are specialized couriers ready to take frozen sex cells on international journeys, she wrote.
Michele Harrison was 41 when she froze 21 of her eggs. By the time she wanted to use them, two years later, only one was viable. Although she did have a baby, her case demonstrates that egg freezing is no guarantee of parenthood, wrote Bonnie Rochman.
What happens if someone dies with eggs in storage? Frozen eggs and sperm can still be used to create new life, but it’s tricky to work out who can make the decision, as I wrote in a previous edition of The Checkup.
Meanwhile, the race is on to create lab-made eggs and sperm. These cells, which might be made from a person’s blood or skin cells, could potentially solve a lot of fertility problems—should they ever prove safe, as I wrote in a feature for last year’s magazine issue on gender.
Researchers are also working on ways to mature eggs from transgender men in the lab, which could allow them to store and use their eggs without having to pause gender-affirming medical care or go through other potentially distressing procedures, as I wrote last year.

The World Health Organization is set to decide whether covid still represents a “public health emergency of international concern.” It will probably decide to keep this status, because of the current outbreak in China. (STAT)
Researchers want to study the brains, genes, and other biological features of incarcerated people to find ways to stop them from reoffending. Others warn that this approach is based on shoddy science and racist ideas. (Undark)
A watermark for chatbots can expose text written by an AI
For example, since OpenAI’s chatbot ChatGPT was launched in November, students have already started cheating by using it to write essays for them. News website CNET has used ChatGPT to write articles, only to have to issue corrections amid accusations of plagiarism. Building the watermarking approach into such systems before they’re released could help address such problems.
In studies, these watermarks have already been used to identify AI-generated text with near certainty. Researchers at the University of Maryland, for example, were able to spot text created by Meta’s open-source language model, OPT-6.7B, using a detection algorithm they built. The work is described in a paper that’s yet to be peer-reviewed, and the code will be available for free around February 15.
AI language models work by predicting and generating one word at a time. After each word, the watermarking algorithm randomly divides the language model’s vocabulary into words on a “greenlist” and a “redlist” and then prompts the model to choose words on the greenlist.
The more greenlisted words in a passage, the more likely it is that the text was generated by a machine. Text written by a person tends to contain a more random mix of words. For example, for the word “beautiful,” the watermarking algorithm could classify the word “flower” as green and “orchid” as red. The AI model with the watermarking algorithm would be more likely to use the word “flower” than “orchid,” explains Tom Goldstein, an assistant professor at the University of Maryland, who was involved in the research.

That’s why the team behind a new decision-making tool hope it will help to clear up some of the misconceptions around the procedure—and give would-be parents a much-needed insight into its real costs, benefits, and potential pitfalls. Read the full story.
