As winter grips the Northern Hemisphere tightly, many of us are happy to retreat to the comfort of our warm homes. But for some animals, this season plays a vital role in the formation of something necessary for their survival, … Continue reading »
Today is the last day of 2012. As you put on your formal wear and get ready to ring in the new year, why not reflect on the animal that’s always in style: the penguin! This year, PLOS ONE published an exciting array of penguin research. Here is a snippet of those penguin papers that attracted media attention and some that flew (or swam) under the radar.
Have you ever wondered just what penguins do with their time? Our next study, entitled “Activity Time Budget during Foraging Trips of Emperor Penguins”, may help to shed some light on a day in the life of a penguin. As the title suggests, researchers tracked and observed penguins on foraging trips in the water and on sea ice. They noted that penguins spent about 70% of their time in the water, diving to depths of over 5 meters. When outside of the water, penguins spent a majority of the time resting. The researchers suggest that resting on sea ice may provide shelter from predators such as leopard seals. For more on this study, check out this video from the supporting information, or visit NBC and The Telegraph.
We now travel from Antarctica to Argentina in search of Magellanic penguins. In “How Much is Too Much? Assessment of Prey Consumption by Magellanic Penguins in Patagonian Colonies”, researchers calculated rates of prey consumption by analyzing the number of wiggles penguins made while diving. Why count wiggles? According to researchers, Magellanic penguins wiggle – that is, undulate up and down – in pursuit of prey. When penguins wiggle during their dive, it is very likely that they have caught their prey.
This evening as you gather with your loved ones to watch the fireworks, you may wonder how to keep warm in the December chill. Do what penguins do and huddle! In the aptly named “Modeling Huddling Penguins”, researchers developed a mathematical model to study the shape and movement of huddling penguins in extreme cold. The researchers simulated a group of huddling penguins and determined wind flow (refer to the image on the left, which is Fig. 1 from the study). They then identified which penguin would be the coldest and moved that penguin downwind; the scenario was repeated under different wind patterns. The researchers found that even if individual penguins work to conserve individual body heat the group as a whole can distribute an even heat loss.
Have a happy new year! We will see you all in 2013.

In this round-up, we would like to share with you some of the PLOS ONE articles covered by the media in 2012. Over one thousand papers published in PLOS ONE were covered in the news! Exciting as it is to see the wide coverage all these papers received, this made it difficult to narrow down the list below to just a few. Some of the papers the media found newsworthy are listed below (in no particular order).
These papers are only a small fraction of more than a thousand that were covered by the media. Visit our Media Tracking Project to see the full list of over 7000 news stories that reported on PLOS ONE research published in 2012. Or follow us on YouTube, SoundCloud and Twitter to keep track of some of the great science multimedia we’ve published this year!
