Scientists Say: Outlier
Data points often fall within a normal range. When one data point sticks out a lot, it might be an outlier.

A robot made with a Venus flytrap can grab fragile objects
Scientists have “borrowed” the hair-trigger leaves of Venus flytraps to make a gentle grabber that can be controlled by a cellphone app.

Newfound technique allows some tree snakes to climb wide trees
When a tree is too wide to climb, brown tree snakes use a lasso-like trick to slowly ascend up to snacks.
