Fujitsu made a wearable for cows, and it could boost breeding efficiency in a huge way

If you already think fitness trackers are only for humans, think again. As it turns out, activity tracking has a host of benefits for livestock too. This week at Mobile World Congress, Japanese tech giant Fujitsu pulled the curtain back on a range of fitness trackers for cattle, which are designed specifically to help farmers increase efficiency around breeding and birthing processes. The Estrus Detection System for Cattle (EDSC), as its called, aims to determine exactly when female cows are biologically primed for artificial insemination.

Fujitsu’s EDSC system is comprised of two main parts: a wearable cattle pedometer, and one stationary receiver that processes tracked data. Female cows walk up to six times as much as regular activity rates when they are in estrus, or “in heat”, according to Fujitsu. By tracking spikes in activity, particularly at night, farmers can determine precisely when a cow is going into the estrus phase. The EDSC system is expected to raise farms’ successful insemination rate to about 65 percent, compared to the 30 percent average success rate when farmers inspect cows by hand every day.

Thanks to the system’s high precision rate, Fujitsu also expects that farmers will be able to take considered steps to ensure either male or female calves, depending on the farm’s requirements at the time. Female offspring are more likely to result from insemination within the first four hours of the estrus phase, while male offspring are statistically more likely from insemination within the last four hours of estrus.

In addition to artificial cattle insemination schedules and decisions about the sex of calves, the system can be used to predict due dates and monitor delivery. Fujitsu demonstrated the full EDSC system at MWC this week. Each cow werable is priced at $150, while the stationary receiver that integrates the data system costs $3,000. EDSC is currently being piloted on farms in Japan and Europe, and it looks like Fujitsu has their sights set on US for future versions of the system.

Every hardware event has that one announcement that isn’t exactly a breakthrough, but rather a rehash of an existing product or service. As far as Google’s latest launch is concerned, that product is the Pixel Buds Pro 2 in a new finish.

Alongside a stacked lineup of phones and gadgets, the Pixel Buds Pro 2 quietly picked up a fifth color option today, and it's easily the most seasonally appropriate one yet.

The Pixel Watch 5 looks familiar, but it can now keep tabs on your blood pressure and insulin resistance
The Pixel Watch 5 bets its whole pitch on sensors smart enough to flag your blood pressure and metabolic trends.

It’s that day of the year again. Google has announced its latest set of hardware, including the new Pixel 11 lineup, and, alongside the Gemini-infused smartphones, a new smartwatch that will remain on the shelves for the rest of 2026 and the first half of 2027. 

Introducing the Google Pixel Watch 5, featuring a familiar round face, a snappier chip, and two health monitoring features that might be enough to sell potential buyers on the device: Blood Pressure Trends and Insulin Resistance Trends (or metabolic health).

Datamaxxing is the latest AI trend, and for once, it could be good for your health goals
Feeding fitness data to AI can turn unexplained health metrics into useful conversations, but trusting it as a doctor is another matter

Datamaxxing sounds like the sort of wellness trend that would involve a spreadsheet, three supplements, and far too much free time. The basic idea is much more sensible. People are feeding data from their wearables into AI chatbots and asking them to explain what all those numbers actually mean. The Wall Street Journal recently documented several people building systems around exactly that idea.

There’s a genuine gap for AI to fill here. A 2026 Nature Communications study found that wearables are good at producing summaries, but much less useful when people want personalized answers about their own data. An AI agent built by the researchers reached 84% accuracy on objective numerical questions.
