Atomization is the process of breaking a liquid into a spray of fine droplets. There are many methods to accomplish this, including jet impingement, pressure-driven nozzles, and ultrasonic excitement. In the images above, a drop has been atomized through vibration of the surface on which it rests. Check out the full video. As the amplitude of the surface’s vibration increases, the droplet shifts from rippling capillary waves to ejecting tiny droplets. With the right vibrational forcing, the entire droplet bursts into a fine spray, as seen in the photo above. The process is extremely quick, taking less than 0.4 seconds to atomize a 0.1 ml drop of water. (Photo and video credit: B. Vukasinovic et al.; source video)
i think i did something actually worthwhile in science this week.
i was asked to review a children’s science book for accuracy, and upon doing so i noted that every scientist mentioned by name was a man, and the vast majority were white. i pointed this out to the publishers in my review letter.
surprisingly, my comments seemed well received. i was thanked for noticing what everyone else had missed, and they told me they were going to change the list of scientists they discussed to be more representative. so, yay? i may have actually had a positive impact on science education?
what am i even doing still stuck at the bench, pipetting shit.

Reverse psychology that's not in psychology. Reverse biology...?
How did you decide to do a project with RNA?
I was having a conversation with someone in our department about how useful and cheap next-gen sequencing is, and how I was considering spending out my grant on a project looking at immune gene expression in spiders. He told me flat out that I wasn’t capable of doing it, because I wouldn’t understand it enough to ever publish. So I used a kit to extract RNA, sent off the samples, read a few books in the meantime, learned to code, wrote the scripts for R and the supercomputer, then did it. I’m writing it up now, and have found some pretty cool stuff! I’m glad I learned it too, since it’s a good skill to have.
TL;DR: some asshole told me I couldn’t do it, so I decided to do it.
hey, your blog is super great and you seem like a beautiful human being. i find you to be super inspiring! i know you get a lot of these questions, but is it okay to punch boys who tell me that i "can't can't be an engineer because I'm a girl"?
Not that I’m advocating violence, but if hypothetically you were to punch a shitty dude for being sexist, you should aim for the solar plexus or the stomach, not the face, because you’re less likely to hurt your hand and you’ll do more damage. Hypothetically of course.

In his classic tale Journey to the Center of the Earth, author Jules Verne dreamed of reaching the center of our planet through volcanic tubes. In the 1960s, scientists took up that challenge and tried to drill down into the earth’s mantle, but abandoned the project due to a lack of funding. Now, a team of scientists aboard the research vessel JOIDES Resolution is working to bore a hole deep into the Atlantis Bank in the Indian Ocean to collect samples of the crust and eventually break through into the mantle. Geologist Henry Dick, co-chief scientist of the expedition, joins Ira for an update on the progress of the project and explains what these samples could reveal about the formation of the planet.
