What is the shape of a falling raindrop? Surface tension keeps only the smallest drops spherical as they fall; larger drops will tend to flatten. The very largest drops stretch and inflate with air as they fall, as shown in the image above. This shape is known as a bag and consists of a thin shell of water with a thicker rim at the bottom. As the bag grows, its shell thins until it ruptures, just like a soap bubble. The rim left behind destabilizes due to the surface-tension-driven Plateau-Rayleigh instability and eventually breaks up into smaller droplets. This bag instability limits the size of raindrops and breaks large drops into a multitude of smaller ones. The initial size of the drop in the image was 12 mm, falling with a velocity of 7.5 m/s. The interval between each image is 1 ms. (Photo credit: E. Reyssat et al.)

That one time my roommate couldn't watch Shane's Asagao Academy stream so I live-texted it to her instead (part 2).

Step Four

Discover that EVERYTHING IS MADE OF CHEMICALS. 

Whew. That was pretty scary, wasn’t it? Education is hard. Learning about scary chemicals is a big adventure. But aren’t you glad you pulled through? I’m glad we had this talk.

The use of 3-D printers has opened up the possibility of on-demand implants, prosthetics, and medical devices. This week, scientists reported that they were able to 3-D-print the first stable ear, bone, and muscle structures out of living cells and implant them in mice. The results were published in Nature Biotechnology. Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine and an author on that paper, describes the challenges of 3-D printing living cells and how the technology could be used in bioengineering body parts.

Day in the life of a scientist

Me, at an art store: I need a paint marker with low toxicity and a delicate tip.

Employee: What kind of project are you working on?

Me: It's for a research project. I just need bright colors.

Employee: What medium are you using? Canvas or paper?

Me: uh....spiders.

Employee: Plastic or felt?

Me: ....live spiders. Like, from the forest.

Employee: ....

Employee: I have to get back to the counter.

Pee the Rainbow

“Here is something a little different! I work in a lab at a large hospital, so we see some interesting things. A coworker of mine collected these urines to make a “pee rainbow.” It only took a few days before we had our full spectrum of color. :) It was then requested that I bring my camera to work and document this endeavor.”
