Wearable fitness tech is evolving from step counters to powerful tools for understanding cardiovascular health. From heart rate variability to blood pressure insights, these devices can guide smarter ...

Somewhere in your skull right now, there is no math department. No region of the brain exists solely to process equations, ...

The old saw tells us you can lead a horse to water. You just can’t make it drink. It’s not about farm animals. It’s about ...

A decade or so ago, reading instruction underwent a public reassessment. Whole language approaches had emphasized immersion in texts and contextual, “cue"-based guessing strategies. The goals were ...

Dear Dr. Roach: My heart rate variability (HRV) on my heart rate tracker has ranged from 12-14 ms for years now. I read that this means something is going on inside me. Do you have any insight into ...

Axiom Math is giving away a powerful new AI tool. But it remains to be seen if it speeds up research as much as the company hopes. Axiom Math, a startup based in Palo Alto, California, has released a ...

A new Murdoch University study has found that cold-blooded animals (ectotherms) are unable to adjust physiologically to daily temperature fluctuations, a limitation that could leave them increasingly ...

Some readers may solve the problem procedurally: line up the two numbers, add the ones column, carry the one, and add the tens to get 43. Others might instead notice a creative shortcut: 29 + 14 is ...

Some kids struggle with math. Now, scientists have pinpointed some of the specific thinking processes and brain regions that might explain why math is a little harder for some than others. When given ...

What is heart rate variability (HRV)? As popular as the metaphor may be, a healthy heart doesn’t beat as regularly as a metronome. In fact, it changes its rhythm with each beat. Heart rate variability ...

Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other anthropogenic forcings account for nearly all observed global surface warming—slightly ...

Five years ago, mathematicians Dawei Chen and Quentin Gendron were trying to untangle a difficult area of algebraic geometry involving differentials, elements of calculus used to measure distance ...
