Wi-Fi enabled tooth sensor tracks your eating and smoking habits

Published within a study conducted by researchers at the National Taiwan University, the team created a sensor designed to be embedded in your mouth in order to track and hopefully curtail bad habits like smoking or overeating. With an accuracy of nearly 94 percent in the current prototype, the sensor can differentiate between eating, speaking, coughing, smoking, drinking and breathing. All of this data is collected and can be sent to your medical professional in order to provide a more accurate history of your daily habits, both negative and positive.

However, the mount would have to be extremely secure in order to avoid the possibility of it becoming loose and potentially swallowed. In addition, the team has to make the device completely waterproof in order to avoid damage to the electronics.

In addition to pursing battery power, the team is also looking into the possibility of adding Bluetooth to the device. This could allow a doctor to download recent data to a smartphone or tablet when you arrive at the office rather than uploading the data to a server over Wi-Fi. However, the researchers want to test the safety of that type of technology being used within the mouth.

Beyond keeping tack of eating and smoking habits, the team believes that dentists could find this technology useful as well. In an interview with the New Scientist, Faculty of General Dental Practice vice-chair Trevor Johnson said “This could have a number of uses in dentistry, for example as a research tool, for monitoring patients who clench or grind their teeth, and for assessing the impact of various dental interventions.”

Rice grain-sized sensor could give robots a delicate touch and keep them from breaking stuff
Sprout Robot

Robots are incredibly precise, but being gentle is not always their strong suit. A machine that can build a car with near-perfect accuracy can still apply too much pressure when working in places where even the smallest mistake matters, like inside a human eye or during delicate surgery. That is why researchers at Shanghai Jiao Tong University are developing a new type of force sensor that could help robots “feel” what they are touching more accurately.

The sensor is tiny, about the size of a grain of rice at just 1.7 millimeters wide, making it small enough to fit inside advanced surgical tools. What makes it especially interesting is that it does not rely on traditional electronics. Instead, it uses light to measure force from every direction, including pressure, sliding movements, and twisting. Here is how it works. At the tip of an optical fiber sits a soft material that slightly changes shape when it comes into contact with something. That tiny deformation alters how light travels through the sensor. The altered light pattern is then sent through optical fibers to a camera, which captures it like an image. Researchers then use a machine learning model to study those light patterns and translate them into precise force readings. In simple terms, the system learns how to “read” touch through light alone, without needing a bunch of wires or multiple separate sensors packed into such a tiny space.

Meta’s own employees are having a hard time digesting AI. Who would’ve thought?
Artificial Intelligence

If you wanted a snapshot of what it looks like when a tech giant tries to force-feed its workforce an AI future, look no further than Meta right now. The company that built its empire on knowing everything about its users has turned that same appetite inward, and its employees are not happy about it. Last month, Meta quietly informed tens of thousands of its U.S. workers that their corporate laptops would begin tracking their keystrokes, mouse movements, clicks, and screen activity. The purpose was to feed that behavioral data into Meta's AI models so they could learn how people actually use computers. The reaction was immediate — within hours, internal comment threads were flooded with anger, confusion, and more than a hundred emoji reactions that left little to the imagination about how employees felt.

When an engineering manager asked how to opt out, Meta's chief technology officer, Andrew Bosworth, had a blunt answer: there was no opt-out, at least not on a company laptop. This is the same company that is also tying AI tool usage to performance reviews, running mandatory "AI Transformation Weeks" to retrain its workforce, and building internal dashboards that gamify how many AI tokens employees consume in a day — a metric so aggressively tracked that some workers started building AI agents to manage their other AI agents. The whole thing started to resemble a feedback loop eating itself.

Sci-fi got the gadgets right, but the vibes wrong
Sci-fi got plenty of consumer tech right, but reality keeps delivering the useful, compromised version of the dream
Officer K looking up at a neon-colored hologram in Blade Runner 2049.

I was recently waiting for an Uber when the GPS decided to lie for sport. The car was somewhere nearby, I was somewhere nearby, and somehow both of us were trapped in that modern ritual of wrong pins, slow turns, vague waving, and "I'm here" messages that help absolutely no one.

That was when I had a very reasonable thought: this is exactly where a hologram of a giant arrow pointing at me would be useful.
