This video, by Dr. Nils Lindström of the University of Edinburgh, which was awarded 3rd place in the 2012 Nikon Small World in Motion Competition, displays the development of live metanephric kidney cells cultured in vitro over a period of four days.
Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber — and how the air we breathe is related to the food we ingest.

At times it feels and looks like Obama’s sense of care for the environment is well.. non existent. Just check the policies if you doubt that. If you want to stay up to date with all things climate adaptation with a reasonable tone do check out climateadaptation for more.
Die-hard republican climate denier breaks down in tears after seeing the climate change movie, Chasing Ice. This is her reaction just as she leaves the theater. The poor lady is trembling and crying as she apologizes to her children. Reblog if you can, thanks a lot!
This is a technique called laryngoscopy. Check out the link above for some background, if you can stomach it. If you’re especially brave, check out this Reddit thread with even more video examples of vibrating vocal folds in all their freaky glory.
This visualization shows the moon’s phase and libration throughout the year 2013, at hourly intervals.
Each frame represents one hour. In addition, this visualization also shows other relevant information, including moon orbit position, subearth and subsolar points, distance from the Earth. Click each graphic to learn more about what it means! Finally, to learn more about this visualization, or to see what the moon will look like at any hour in 2013, visit here.
Learn about your lunar satellite, folks. It’s the only one we have. You might notice the Moon is sort of rocking back and forth. That’s called libration, and you can learn how it works here.
Time - Bill Nye the Science Guy What exactly is time? A fun and simple explanation of time and Einstein’s theory of General Relativity. There’s also some incredibly badass clips of Einstein speaking that I would love to make gifs out of.
Do you remember 1982’s “TRON” movie? The plot: A computer programmer (epic: Jeff Bridges) is digitized inside the software world of a mainframe computer, where he interacts with various programs in his attempt to get back out. I loved the light cycle races and strange solar wind ships…
Back in the real word the ISS is in a way one of these solar ships, constantly rotating around us. A tiny white spot, as it can be seen racing over the sky from time to time, when illuminated by the sunset (and sunrise ;).
This Video was achived by “stacking” image sequences provided by NASA from the Crew at International Space Station (see also fragileoasis.org/blog/2012/3/on-the-trails-of-stars/). These “stacks” create the Star Trails, but furthermore make interesting patterns visible. For example lightning corridors within clouds, but they also show occasional satellite tracks (or Iridium Flashes) as well as meteors - patterns that interrupt the main Star Trails, and thus are immediately visible.
The many oversaturated hot pixels in some of the scenes are the inevitable result of ultrahigh ISO settings the Nikon D3s in ISS-use are pushed to for keeping exposure times short by all means (owed to the dramatic speed the ISS travels). As there are no dark frames or RAW data currently available, hot pixels are not easy to remove.
FRONTLINE explores the massive shift in public opinion on climate change
Four years ago, climate change was a hot issue and politicians from both sides seemed poised to act. Today public opinion on the climate issue has cooled considerably. Politicians either ignore it or proclaim their skepticism. What’s behind this massive reversal? On Oct 23, FRONTLINE goes inside the organizations that fought the scientific establishment to shift the direction of the climate debate.
