Need To Know
Siri Gets a Makeover
Apple yesterday unveiled an AI-powered Siri that company executives say can draw on message history, photos, the web, and more to answer open-ended questions and complete tasks, like brainstorming recipes, updating a calendar, and drafting texts. Watch demo (via Facebook).
The announcement comes nearly two years after Apple promised a highly anticipated Siri revamp. The tech giant last month agreed to pay $250M to settle a class-action lawsuit alleging it misled millions of customers about the digital assistant's AI capabilities. Experts say the version presented yesterday will likely bring Apple closer to competing with chatbots such as ChatGPT, Claude, and Gemini. It was developed in collaboration with Google, allowing Apple to focus on user experience rather than building underlying AI models.
The new Siri will be widely available in the US this fall as a free software update. Listen to its more expressive, customizable voice here.
Citizenship Revocations
The Justice Department announced yesterday that it will work to strip citizenship from 17 naturalized US citizens, the largest cohort to date. The announcement comes weeks after the DOJ named a dozen other cases.
Federal law allows denaturalization if individuals lied on their immigration forms, including by failing to disclose crimes. While most denaturalization cases are successful, the process is legally complex and can stall in federal courts. From 1990 to 2017, the DOJ worked to denaturalize an average of 11 US citizens per year. That pace has since increased to roughly 15 per year.
The latest batch of cases—among hundreds the DOJ intends to pursue—includes people from countries including Haiti, Mexico, the Philippines, and the former Yugoslavia. Five were accused of child sexual abuse crimes, including a former Catholic priest from Colombia. Others were accused of money laundering, fraud, and crimes related to using false identities. If denaturalized, the individuals may face prison time or deportation. See their profiles.

Sleep Without Sleep
For the first time, researchers have identified a way to trigger some of sleep's memory-restoring effects in awake mice, according to a study released yesterday. The finding suggests the brain may not need to be fully asleep to perform some of its overnight maintenance.
Non-REM sleep, which accounts for roughly 80% of an adult human's slumber, helps the brain consolidate memories by strengthening key neural connections and weakening less useful ones (scroll to visualize the anatomy of sleep). In the study, researchers used light pulses to switch targeted neurons on and off in the sleep-deprived mice's brains for 30-minute intervals, recreating the firing pattern observed during sleep. Treated mice performed memory tasks similarly to well-rested mice, indicating the specific pattern of neural activity matters more than unconsciousness.
In nature, dolphins can shut down one half of their brain at a time, allowing them to keep swimming and surface for air. Migratory birds also appear to do something similar in flight. Watch how it works.
