Deep learning can almost perfectly predict how ice forms
The news: Researchers have used deep learning to model more precisely than ever before how ice crystals form in the atmosphere. Their paper, published this week in PNAS, hints at the potential to significantly increase the accuracy of weather and climate forecasting.
How they did it: The researchers used deep learning to predict how atoms and molecules behave. First, models were trained on small-scale simulations of water molecules to help them predict how electrons in atoms interact. The models then replicated those interactions on a larger scale, with more atoms and molecules. It’s this ability to precisely simulate electron interactions that allowed the team to accurately predict physical and chemical behavior.
Why it matters: If researchers could model how ice forms more accurately, it could give a big boost to weather prediction overall, especially those involving whether and how much it’s likely to rain or snow. It could also aid climate forecasting by improving the ability to model clouds, which affect the planet’s temperature in complex ways. Read the full story.
China has censored a top health information platform
China has censored DXY, the country’s leading health information platform and online community for Chinese doctors. On August 9, DXY fell silent across its social media channels, where it boasts over 80 million followers. While Weibo offered the vague explanation that the platform’s five channels had violated “relevant laws and regulations,” Nikkei Asia reported that the order came from regulators and won’t end without official approval.
In the increasingly polarized social media environment in China, healthcare is becoming a target for controversy. The suspension has met with a gleeful social reaction among nationalist bloggers, who accuse DXY of receiving foreign funding, bashing traditional Chinese medicine, and criticizing China’s health-care system, illustrating just how politicized health topics have become.

Podcast: How to craft effective AI policy
When are policy makers going to catch up with the speed of AI innovation? The latest episode of our award-winning podcast, In Machines We Trust, examines what it will take to make effective AI policy and equitable access to technology. It was recorded before a live audience at MIT Technology Review’s annual AI conference, EmTech Digital. Listen to it for yourself.

The big story
Dementia content gets billions of views on TikTok. Whose story does it tell?
A dementia diagnosis can instantly change how the world sees someone. The internet, at its best, can help make the reality of living with dementia more visible. And for some, the internet is the only place they can connect with others going through the same thing. But among the popular #Dementia hashtag on TikTok, it’s easy to find viral videos in which care partners mock dementia patients and escalate arguments with them on camera.
Creators have not settled on the ethics of making public content about someone who may no longer be able to consent to being filmed. Meanwhile, people who are themselves living with dementia are raising their own questions about consent, and emphasizing the harms caused by viral content that perpetuates stereotypes or misrepresents the full nature of the condition.
