The YouTube baker fighting back against deadly “craft hacks”
Ann Reardon is probably the last person whose content you’d expect to be banned from YouTube. A former Australian youth worker and a mother of three, she’s been teaching millions of loyal subscribers how to bake since 2011. But the removal email was referring to a video that was not Reardon’s typical sugar-paste fare.
Since 2018, Reardon has used her platform to warn viewers about dangerous new “craft hacks” that are sweeping YouTube, tackling unsafe activities such as poaching eggs in a microwave, bleaching strawberries, and using a Coke can and a flame to pop popcorn.
The most serious is “fractal wood burning”, which involves shooting a high-voltage electrical current across dampened wood to burn a twisting, turning branch-like pattern in its surface. The practice has killed at least 33 people since 2016.
On this occasion, Reardon had been caught up in the inconsistent and messy moderation policies that have long plagued the platform and in doing so, exposed a failing in the system: How can a warning about harmful hacks be deemed dangerous when the hack videos themselves are not?

DeepMind’s new chatbot uses Google searches plus humans to give better answers
The news: The trick to making a good AI-powered chatbot might be to have humans tell it how to behave—and force the model to back up its claims using the internet, according to a new paper by Alphabet-owned AI lab DeepMind.
How it works: The chatbot, named Sparrow, is trained on DeepMind’s large language model Chinchilla. It’s designed to talk with humans and answer questions, using a live Google search or information to inform those answers. Based on how useful people find those answers, it’s then trained using a reinforcement learning algorithm, which learns by trial and error to achieve a specific objective. Read the full story.

The big story
One man’s crusade to end a global scourge with better salt
When he was growing up, Venkatesh Mannar and his siblings treated the family saltworks as their playground. After several years in the United States, first studying and then working at salt producers that used giant mechanized harvesters, he returned to India in 1972 to run his business.
After helping to persuade countries in Asia, Africa, and Latin America to iodize their salt to eliminate iodine deficiency, which causes problems ranging from hypothyroidism to learning difficulties, Mannar turned his attention to another element that many people don’t get enough of: iron. A lack of it is one cause of anemia, which affects over 1.6 billion people, causing dizziness, poor maternal and infant health, and decreased cognitive function.
Mannar eventually made defeating anemia with iron-enriched salt part of his life’s mission. Adding iron to salt that is already iodized has turned out to be a real technical challenge, and getting manufacturers and the public to adopt it is another problem entirely. But if the effort succeeds, Mannar and his backers hope to add yet more essential minerals, turning humble table salt into one of the most potent public health tools the world has at its disposal.
