Calcium carbonate, anyone? This is a calcareous (uses calcium carbonate, CaCO3, for defense and structural support) coral at 40x, 100x, 400x, 1200x, and 3000x. The large “rocks” that are wedged in the coral are actually sand particles. Sand often consists of quartz, silica, calcium carbonate, and whatever shells that have been ground down for decades by dynamic seas. The holes covered with sand would have once housed several polyps that fed on drifting phytoplankton and zooplankton. Take note that the calcium carbonate crystals have a definite molecular geometry that determines their shape, even when only measuring micrometers in width, length, and height.

neural tube closure in salamander embryos

that sounds boring, but seriously, just watch this

you won’t regret it

Every human who has ever lived on this Earth has undergone this process. If the neural tube fails to close properly, serious nervous system issues can emerge that are often fatal. This can include newborn babies who are born with no proper brain and only a brain stem that partakes in basic functions such as regulation of blood pressure, breathing rate, and heart rate. The child is physically incapable of processing and responding to their environment and often die from associated complications. If you are reading this that means you did this right. The closing of the neural tube is critical to the further development of a proper nervous system that includes a brain and spinal cord. The process is called gastrulation. The first fold of the embryo forms the digestive system and the second fold forms into the neural tube that forms the nervous system.

Oceanic phytoplankton blooms imaged from space by Envisat.  Plankton blooms occur in regions of the ocean that have optimal temperature, sunlight, and nutrient supply for marine algae to grow exponentially.  Most blooms are composed of coccolithophores, single celled organisms which grow disk-like exoskeletons of calcium carbonate.  Trillions of these disks color the water white, showing the phytoplankton density and beautiful fluid dynamics of ocean currents.
