The immune system part 1.

Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy — your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes — the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we’ll explain how all of these elements work together to save the day if you happen to slip on a banana peel.

Scientist Carl Sagan said many times that “we are star stuff,” from the nitrogen in our DNA, the calcium in our teeth, and the iron in our blood.

It is well known that most of the essential elements of life are truly made in the stars. Called the “CHNOPS elements” – carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur – these are the building blocks of all life on Earth. Astronomers have now measured of all of the CHNOPS elements in 150,000 stars across the Milky Way, the first time such a large number of stars have been analyzed for these elements.

“For the first time, we can now study the distribution of elements across our Galaxy,” says Sten Hasselquist of New Mexico State University. “The elements we measure include the atoms that make up 97% of the mass of the human body.”

A while ago I got an idea: how awesome would it be to use 4D ultrasound to scan my unborn baby and make a VR experience of that. So I talked my girlfriend over even though the idea felt a bit weird and almost scary.

How to make it happen? I searched for similar cases online, but couldn’t find any. All I could find was some examples of using ultrasound images for a 3D print of your unborn baby. So this was the first time in the world someone was doing this. Luckily I got people at the Aava Medical Centre excited about the idea, and they helped me forward. I also contacted GE, a manufacturer of 4D ultrasound systems, and they advised me how to extract the right kind of files from the ultrasound machine.
