Pygmy Seahorses: Masters of Camouflage – Video
Tiny and delicate, pygmy seahorses survive by attaching to vibrant corals where they become nearly invisible to both predators and researchers. Now, biologists at the California Academy of Sciences have successfully bred them in captivity for the first time. Finally, they’re able to study the seahorses’ amazing act of camouflage up close.

Traces of the Sun from NASA & György Bajmóczy
Here’s a special treat to celebrate today’s Winter Solstice,
the first day of winter, and in the northern hemisphere,
the shortest day of the year.
Based on 116,000 images from a fixed position ASI 120 camera, György selected photos to display solar movements over the course of the day and the year. You won’t see this anywhere else.
Link to Traces of the Sun video on NASA website. Two minutes long.
Explanation from NASA website:
To celebrate, watch this amazing timelapse video tracing the Sun’s apparent movement over an entire year from Hungary. During the year, a fixed video camera captured an image every minute. In total, 116,000 exposures follow the Sun’s position across the field of view, starting from the 2015 June 21 solstice through the 2016 June 20 solstice. The intervening 2015 December 22 solstice is at the bottom of the frame. The timelapse sequences constructed show the Sun’s movement over one day to begin with, followed by traces of the Sun’s position during the days of one year, solstice to solstice. Gaps in the daily curves are due to cloud cover. The video ends with stunning animation sequences of analemmas, those figure-8 curves you get by photographing the Sun at the same time each day throughout a year, stepping across planet Earth’s sky.

Hidden Perils of Permafrost – Video

What Gall! The Crazy Cribs of Parasitic Wasps – Video
Plenty of animals build their homes in oak trees. But some very teeny, tricky wasps make the tree do all the work. And each miniature mansion the trees build for the wasps’ larvae is weirder and more flamboyant than the next.
