Via skeptv, New Scientist reports on this time lapse video of snail development from embryo to hatching:
Oliver Tills of Plymouth University, UK, and colleagues tracked the timing of 12 different events – including the formation of the eyes and the shell – over the two weeks it takes embryos of the pond snail Radix balthica to develop. They then compared these figures with those obtained from the snail’s parent (R. balthica is hermaphroditic so can have just a single parent).
There are more videos with cells in the archives.
German photographer Stefan Diller has made micro worlds into immense and detailed landscapes to fly over. After three years of work, he’s refined a mix of scanning electron microscope (SEM) technology with “micro-movie camera” software. Thousands of photos — 1500 frames for one minute of footage — are taken at different positions around the specimen. These images are then animated together into a video process called Nanoflight, as shown in this rather jaw-dropping video.
And even the still photographs mesmerize. Be sure to check out Diller’s site for SEM images of animals, plants, and materials.
What would you photograph with a scanning electron microscope? And what do you imagine it would look like?
What does it look like underneath a lake covered with Antarctic ice? McGill University doctoral student and scientific diver Michael Becker shares the view in this New York Times video under Lake Untersee, Antarctica.
In the blog post, he also explains the prep behind keeping the dive safe — note that yellow tether that keeps divers in communication with their team and leads them back to safety — and what they are looking for in the lake sediment: precisely described data and carefully collected samples that help illuminate the history of the lake and its organisms. Brrrrr.
