Using His Dedicated Solar Telescope, The Photographer Captured 160,000 Frames Over 3 Hours, Then Selected

Using his dedicated solar telescope, the photographer captured 160,000 frames over 3 hours, then selected the top 25% to create this time-lapse. Several prominent prominences are visible on the edge, and he even captured a small flare erupting from an active region. via astronomybasics

Surprise Discovery Shows These Sharks Don't Need to Keep Moving

You might have heard that all sharks – if not all fish – must keep moving to maintain the constant flow of water and oxygen across their gills. While most fishes can actually stop for a break, opening and closing their mouth to keep the water flowing, a few species really do need to keep on keeping on. These are called obligate ram ventilators. Unlike their more sedentary cousins, they cannot use their mouth to pump water through their gills while at rest. Biologists thought the gray reef shark (Carcharhinus amblyrhynchos) was one of them.

Not only dogs, but certain cats also enjoy playing fetch, as revealed by recent research. A significant number of felines seem to have acquired this behavior independently, without deliberate training from their human companions. Interestingly, the study indicates that in most instances, these cats took the initiative to start and conclude the play sessions themselves. This implies that while cats may chase and bring back objects, they prefer doing so according to their own preferences, as detailed in a recent publication in Scientific Reports.
