At the close of his show at the Royal Albert Hall on September 28, legendary guitarist David Gilmour invited Benedict Cumberbatch onstage to perform vocals on the quintessential Pink Floyd song “Comfortably Numb“. The smiling actor seemed as if he could barely hold back his excitement as he sung the verses leading up to Gilmour’s iconic chorus.

In the short film “Coral Colors“, the filmmakers of myLapse out of Barcelona, Spain have captured the absolute beauty of coral, showcasing the gorgeous colors and movement through a stunning timelapse of amazing macro footage. The project was created to call attention to the harmful effects of global warming on such great natural wonders as the Great Barrier Reef.

In this video we have tried to show movement and the enormous chromatic beauty of corals, a kind of marine animals that despite being one of the oldest animals on our planet, are mostly unknown. You will discover its stunning beauty, its spectacular colors and the mystery of his movements.To capture these images it was necessary to apply the technique of time lapse as the slow movements of these animals are very difficult to see at a glance. The use of macro lens gives a large enough vision to contemplate the huge variety of colorful species.

Vlogger Chris Poole took a break from his busy life with Cole and Marmalade in order to visit the amazing Cat House on the Kings in Parlier, California to learn what it’s like to care for over 700 felines at the state’s largest no-cage, no-kill, lifetime cat sanctuary and adoption center. In doing so, Poole spent time with founder Lynea Lattanzia who relies on donations to keep the sanctuary running.

Not only do they provide a home for hundreds of cats and adopt as many as possible in the past few years, they spent 250 thousand dollars on spaying and neutering cats and dogs and this is what makes the biggest difference and helps keep pets out of shelters. They don’t receive any government support everything is entirely donation driven and costs around a hundred thousand dollars a month to operate.

Information on how to make a donation, sponsor a cat or volunteer for this very worthy cause is available through their website.

PBS Idea Channel host Mike Rugnetta looks at the phenomenon of people commenting “First!” on YouTube videos. Rugnetta provides a defense of the habit, and breaks down possible reasons why people do it and even the significance the behavior has on interactions in comment sections.

Like a sheet white winter field covered in a fresh layer of snow, unperturbed by man, there stands, if for only the briefest of moments, the empty youtube comment section. That is: empty until some speedy, enterprising soul arrives on the scene. Keyboard ready, fingers quaking in anticipation. Hastily, they hammer out their message to the world, the one to address the serenity of that blank, digital canvas below a youtube video. They write, FIRST! The question, then, is: why might there be a premium placed on being early? And why might there be additional status in claiming that earliness via comments? And why does it get a rise out of people. Why people like being first at things. Why is… YouTube… of all places… a major host to the first phenomena? Watch the episode to find out and let us know what you think in the comments below!

In a follow-up comment response video, Rugnetta reads some comments by users that seek to further explain “First!”
