How Twitter’s “Teacher Li” became the central hub of China protest information
As protests against rigid covid control measures in China engulfed social media in the past week, one Twitter account has emerged as the central source of information: @李老师不是你老师 (“Teacher Li Is Not Your Teacher”).
People everywhere in China have sent protest footage and real-time updates to the account through private messages, and it has posted them, with the sender’s identity hidden, on their behalf.
The man behind the account, Li, is a Chinese painter based in Italy, who requested to be identified only by his last name in light of the security risks. He’s been tirelessly posting footage around the clock to help people within China get information, and also to inform the wider world.
The work has been taking its toll—he’s received death threats, and police have visited his family back in China. But it also comes with a sense of liberation, Li told Zeyi Yang, our China reporter. Read the full story.
Biotech labs are using AI inspired by DALL-E to invent new drugs
The news: Text-to-image AI models like OpenAI’s DALL-E 2—programs trained to generate pictures of almost anything you ask for—have sent ripples through the creative industries. Now, two biotech labs are using this type of generative AI, known as a diffusion model, to conjure up designs for new types of protein never seen in nature.
Why it matters: Proteins are the fundamental building blocks of living systems. These protein generators can be directed to produce designs for proteins with specific properties, such as shape or size or function. In effect, this makes it possible to come up with new proteins to do particular jobs on demand. Researchers hope that this will eventually lead to the development of new and more effective drugs.

Your microbiome ages as you do—and that’s a problem
We’re all crawling with bugs. Our bodies are home to plenty of distinct ecosystems that host microbes, fungi, and other organisms that are crucial to our wellbeing. These ecosystems appear to change as we age—and these changes can potentially put us at increased risk of age-related diseases.
The big questions are: what can we do to maintain a happy microbiome—and, even if we manage to achieve it, will it actually help us to keep age-related illnesses at bay? Read the full story.

The big story
For years, microbiologist Sabra Klein has painstakingly made the case that sex—defined by biological attributes such as our sex chromosomes, sex hormones, and reproductive tissues—can influence immune responses.
Through research in animal models and humans, Klein and others have shown how and why male and female immune systems respond differently to the flu virus, HIV, and certain cancer therapies, and why most women receive greater protection from vaccines but are also more likely to get severe asthma and autoimmune disorders.
Klein has helped spearhead a shift in immunology, a field that long thought sex differences didn’t matter—and she’s set her sights on pushing the field of sex differences even further. Read the full story.
