Can your Apple Watch detect pregnancy?
Researchers used a mix of behavioral and biometric data to train an artificial intelligence model.
The result? The system correctly predicted pregnancy in 92% of cases. It is not meant to replace a lab test, but it could help women spot early signs before they even suspect anything.

The research comes from the Apple Heart and Movement Study, which collected over 15 billion data points from more than 162,000 participants. The data came through the everyday use of the Apple Watch and iPhone. For the pregnancy research, the model analyzed information from 430 reported pregnancies and more than 25,000 non-pregnant participants. The AI looked at more than heart rate and temperature. It also examined movement patterns, sleep habits and exercise routines.
According to the study, changes in behavior provided strong clues. For example, a shift in walking gait or a change in bedtime routine could signal early pregnancy.
"Pregnancy results in substantial changes to an individual's behavior," the researchers said. "Hence, this task acts as a clear example of the complementary nature of modeling both types of data."
Pregnancy was just one of several health conditions the AI model learned to identify. The researchers also tested the model on other health issues with strong results. It predicted diabetes with 82% accuracy, infection with 76% accuracy and injury with 69% accuracy. These findings suggest that AI-powered wearables may soon do much more than count steps or track sleep. They could help detect serious health changes before symptoms even appear.
Even with these promising results, trust remains a major barrier in women's health technology. Privacy concerns are growing, especially when it comes to sensitive data like menstrual cycles or pregnancy. In 2023, the Federal Trade Commission fined the popular app Premom for sharing user data without consent.
A recent FTC study confirmed growing skepticism. Women are less likely to trust apps that collect reproductive health information, especially when the companies do not make their data practices clear. That raises an important question. Even if the Apple Watch can detect early signs of pregnancy, would users want it to?
Apple continues to build tools for reproductive and maternal health. In 2019, it added menstrual cycle tracking to the Health app. In 2023, it introduced a pregnancy tracking feature for the Apple Watch. The company has not announced any plans to turn the AI findings into a consumer feature. But this research shows where Apple's focus may be headed. With support from public health officials calling for widespread use of wearables, Apple could play a key role in shaping the future of personalized healthcare.

This study shows that your Apple Watch may someday detect major health changes before you notice them. It is not a replacement for a doctor, but it could become a powerful early-warning tool. Still, trust and transparency will matter just as much as the technology itself.

SoftBank's AI investment spree to be in focus on at Q1 earnings
By Anton Bridge TOKYO (Reuters) -When Japan's SoftBank Group reports earnings on Thursday, its mammoth investments in artificial intelligence companies are set to take the spotlight. Analysts and investors are keen for updates on how they will be financed, the timeline for returns to materialise and whether assets will be sold to fund the new projects. SoftBank has embarked on its biggest spending spree since the launch of its Vision Funds in 2017 and 2019. It is leading a $40 billion funding round for ChatGPT maker OpenAI. SoftBank has until the end of the year to fund its $22.5 billion portion, although the remainder has been subscribed, according to a source familiar with the matter. It is also leading the financing for the Stargate project - a $500 billion scheme to develop data centres in the United States, part of its effort to position itself as the "organiser of the industry," founder Masayoshi Son said in June. SoftBank has yet to release details on what kinds of returns its financing of the Stargate project could generate. The extent of third-party investment will determine what other financing tools, such as bank loans and debt issuance, it may have to deploy. In July, SoftBank raised $4.8 billion by selling off a portion of its holding in T-Mobile. "If other sources of capital are less supportive, SoftBank could look to asset-backed finance, which is collateralised by equity in other holdings," Macquarie analyst Paul Golding said. The Japanese conglomerate is expected to post a net profit of 127.6 billion yen ($865 million) in the April-June quarter, according to the average estimate of three analysts polled by LSEG. That would mark SoftBank's second consecutive quarter of profit and follow its first annual profit in four years when it was helped by a strong performance by its telecom holdings and higher valuations for its later-stage startups. Its results are, however, typically very volatile and difficult to estimate due to manifold investments, many of which are not listed. SoftBank's performance in exiting from investments and distributing profits has been patchy of late. The Vision Funds had made a cumulative investment loss of $475 million as of end-March. That said, 13 of 18 analysts have a "buy" or "strong buy" rating for SoftBank's stock, according to LSEG. Although there is some concern in the market that AI-related valuations have become bubbly, they continue to climb. OpenAI is in early-stage discussions about a stock sale that would allow employees to cash out and could value the company at about $500 billion, according to the source - a huge jump from its current valuation of $300 billion.

"Clankers": A robot slur emerges to express disdain for AI's takeover
AI is everywhere whether you like it or not, and some online have turned to a choice word to express their frustration. Why it matters: Referring to an AI bot as a "clanker" (or a "wireback," or a "cogsucker") has emerged as a niche, irreverent internet phenomenon that illuminates a broader disdain for the way AI is overtaking technology, labor, and culture. State of play: The concerns range from major to minor: people are concerned that AI will put them out of a job, but they're also annoyed that it's getting harder to reach a human being at their mobile carrier. "When u call customer service and a clanker picks up" one X post from July reads, with over 200,000 likes, alongside a photo of someone removing their headset in resignation. "Genuinely needed urgent bank customer service and a clanker picked up," reads another from July 30. Here's what to know: Where "clanker" comes from Context: The word is onomatopoeic, but the term can be traced back to Star Wars. It comes from a 2005 Star Wars video game, "Republic Commando," according to Know Your Meme. The term was also used in 2008's Star Wars: The Clone Wars: "Okay, clankers," one character says. "Eat lasers." Robot-specific insults are a common trope in science fiction. In the TV Show Battlestar Galactica, characters refer to the robots as "toasters" and "chrome jobs." "Slang is moving so fast now that a [Large Language Model] trained on everything that happened before... is not going to have immediate access to how people are using a particular word now," Nicole Holliday, associate professor of linguistics at UC Berkeley, told Rolling Stone. "Humans [on] Urban Dictionary are always going to win." How people feel about AI Anxiety over AI's potential impact on the workforce is especially strong. By the numbers: U.S. adults' concerns over AI have grown since 2021, according to Pew Research Center, and 51% of them say that they're more concerned than excited about the technology. Only 23% of adults said that AI will have a very or somewhat positive impact on how people do their jobs over the next 20 years. And those anxieties aren't unfounded. AI could wipe out half of all entry-level white-collar jobs — and spike unemployment to 10-20% in the next one to five years, Anthropic CEO Dario Amodei told Axios in May. And the next job market downturn — whether it's already underway or still years off — might be a bloodbath for millions of workers whose jobs can be supplanted by AI, Axios' Neil Irwin wrote on Wednesday. People may have pressing concerns about their jobs or mental health, but their annoyances with AI also extend to the mundane, like customer service, Google searches, or dating apps. Social media users have described dating app interactions where they suspect the other party is using AI to write responses. There are a number of apps solely dedicated, in fact, to creating images and prompts for dating apps. Yes, but: Hundreds of millions of people across the world are using ChatGPT every day, its parent company reports. What we're watching: Sens. Ruben Gallego (D-AZ) and Jim Justice (R-WV) introduced a bipartisan bill last month to ensure that people can speak to a human being when contacting U.S. call centers. "Slur" might not be the right word for what's happening People on the internet who want a word to channel their AI frustrations are clear about the s-word. The inclination to "slur" has clear, cathartic appeal, lexical semantician Geoffrey Nunberg wrote in his 2018 article "The Social Life of Slurs." But any jab at AI is probably better classified as "derogatory." "['Slur'] is both more specific and more value-laden than a term like "derogative," Nunberg writes, adding that a derogative word "qualifies as a slur only when it disparages people on the basis of properties such as race, religion, ethnic or geographical origin, gender, sexual orientation or sometimes political ideology." "Sailing enthusiasts deprecate the owners of motor craft as 'stinkpotters,' but we probably wouldn't call the word a slur—though the right-wingers' derogation of environmentalists as 'tree-huggers' might qualify, since that antipathy has a partisan cast."
