Lumen review: a metabolism breathalyzer for the patient

Wearable robot, why not?

Researchers at the University of Maryland’s Small Artifacts Lab are working on a “wearable robot” called Calico. It appears that you sew a magnetic track onto your clothing, which Calico uses to run up and down your body.

The most obvious use case here seems to be fitness — Calico can count reps, track your heart rate and water consumption, and check your form during workouts. So, you know, you could work out with a smart watch, or you could work out with a tiny metal thing scurrying all over you. To each their own.

It is ridiculously cute, though.

Strava’s heatmaps may not be as anonymous as you think.

Strava’s heatmaps can be handy if you’re scoping out new running, cycling, and hiking routes, as it helps visualize popular areas. However, researchers discovered they could reverse-engineer where a Strava user lives — even though heatmaps are created through anonymized, aggregated data.

You can read through the findings (PDF), but essentially, the more active the user, the easier it was for researchers to find their home addresses — especially in remote areas. If that creeps you out, go to Settings > Privacy Controls > Aggregated Data Usage to opt out.
