PLOS ONE’s Top 5 Videos of 2014


Throughout the year we highlight research images that are worth a thousand words. For this year-end list, we’d like to extend the category to our research videos. Here, we’ve highlighted some of this year’s most popular videos, published in the Supporting Information of research articles.

To read the full research article associated with each video, click the links in the descriptions below them.


Nighttime Chimp Raids

What monkey business are these chimps up to at night? Wild chimpanzees living in disturbed habitats may raid nearby agricultural fields for maize at night to avoid detection by their human neighbors.


Tracking Dino Tracks

Perhaps a dinosaur chase is up to your speed? This model of a dinosaur chase was digitally reconstructed from theropod and sauropod footprints excavated 70 years ago.


Otter Talk

These giant otters communicate with one another using different calls in a surprisingly diverse vocal repertoire. Young giant otters beg for food from the adults using a contact call in this video.


Say Hello to the Hemihelix

Scientists define and describe a new shape using rubber bands—and they have the video evidence to show how it forms. This shape, a hemihelix, is rarely seen in Nature and could provide clues for fabricating 3D shapes from flat parts.


New Caledonians Rule

This video soars above all others as the most popular video from 2014, with 377,000 views at the time of this post. A New Caledonian crow drops objects of different sizes and densities into tubes of water, demonstrating that it may understand water displacement at the same level as a 5-7 year-old child.
