It's tantamount to trying to measure the surface of the earth, from Mount Everest...all the way down to the height of a raisin, and be able to see it all in detail.

It's still just an anomaly, because when you measure tornado trends, you do it over a scale of decades, not three to four years. If this were to go on two to three more years, then you start to look harder. But it is something to note.

What we can measure is how hard we are trying. Measures of effort may be a more useful indicator than estimated rates of species loss. For example, we can measure the number of new protected areas being established and ask if they have sufficient budgets.

The device can identify diseases by sensing chemical patterns carried in the breath.

These volatile biomarkers are free for the asking and taking.

We're really thinking about early intervention.
