A new method developed by MIT researchers can accelerate a privacy-preserving artificial intelligence training method by about 81%. This advance could enable a wider array of resource-constrained edge devices, like sensors and smartwatches, to deploy more accurate AI models while keeping user data secure.

The MIT researchers boosted the efficiency of a technique known as federated learning, which involves a network of connected devices that work together to train a shared AI model.

In federated learning, the model is broad...

AI model uses glucose spikes to reveal hidden diabetes risk before symptoms appear

AI model detects hidden diabetes risk by reading glucose spikes

To diagnose either type 2 diabetes or pre-diabetes, clinicians typically rely on a lab value known as HbA1c. This test captures a person’s average blood glucose levels over the previous few months. But HbA1c cannot predict who is at highest risk of progressing from healthy to prediabetic, or from prediabetic to full-blown diabetes.

Now, scientists at Scripps Research have discovered that artificial intelligence can use a combination of other data—including real-time glucose levels from wearable monitors—to provide a more nuanced view of diabetes risk.

The new model, described in Nature Medicine, uses continuous glucose monitor (CGM) data alongside gut microbiome, diet, ph...

New AI model can estimate a person’s true biological age from five drops of blood

Top Left: A small blood sample is analyzed to measure 22 key steroids, and the data is fed into an AI system to calculate biological age. Top Right: The AI-predicted biological age (BA) shows a general correlation with chronological age (CA), but individual differences widen over time. Bottom: Using the metaphor of a “river widening as it flows downstream,” the illustration visualizes how biological age evolves with the passage of time. Credit: Zi Wang

We all know someone who seems to defy aging—people who look younger than their peers despite being the same age. What’s their secret? Scientists at Osaka University (Japan) may have found a way to quantify this difference...

An AI System has reached Human Level on a Test for ‘General Intelligence’—here’s what that means

A new artificial intelligence (AI) model has just achieved human-level results on a test designed to measure “general intelligence.”

On December 20, OpenAI’s o3 system scored 85% on the ARC-AGI benchmark, well above the previous AI best score of 55% and on par with the average human score. It also scored well on a very difficult mathematics test.

Creating artificial general intelligence, or AGI, is the stated goal of all the major AI research labs. At first glance, OpenAI appears to have at least made a significant step towards this goal.

While skepticism remains, many AI researchers and developers feel something just changed. For many, the prospect of AGI now seems more real, urgent and closer than anticipated. Are they right?
