Imagine you met a girl at a barbeque who asked you to lick your elbow. Would you try it? Would you make an excuse to get away? What if you did both at precisely the same time?
Using ideas from quantum physics and cosmology, the play Constellations addresses the universal question, what if? What would our lives be like if we had made a different choice? If we said the same words slightly differently? This is the story of a cosmologist named Marianne (Ginnifer Goodwin) and Roland, a bee keeper (Allen Leech) and every decision they ever and never made.
What makes the Alien franchise so impactful is how utterly terrifying the titular Aliens are. These creatures are so grotesque and foreign to audiences, particularly in their reproductive strategy, that fans are simultaneously horrified and fascinated by what is on screen. Perhaps unknown to many viewers, the lifecycle of Xenomorph XX121 from the films is not so unlike that of many common parasites found on our planet. The rest of this essay will compare the biology of the Xenomorphs to parasitoid wasps and nematomorph worms from Earth to illustrate how close to reality the biology of these aliens is and to discuss this exceptional instance of science inspiring artists.
From supernovas to rain, humans to amoebas, all matter can be broken down into three key particles: electrons, protons, and neutrons. But over the years, scientists discovered even more particles, and that neutrons and protons could be broken down into even smaller parts, called elementary particles. Physicists created a theory called the Standard Model to interpret how elementary particles comprise the universe. The model is often depicted as a gigantic equation or as a periodic table of particles as a way to describe complex particle interactions. Strangely enough, some of these interactions are reminiscent of a time in our lives that we’re all too familiar with – high school.
In November of 2016, you may have seen a version of a headline like this: “Male birth control study nixed after men can’t handle side effects women face daily”. Steeped in some truth (a study was indeed cancelled after men experienced harsh side effects similar to what many women experience) and masked by outrage (from readers and authors who didn’t know that the severity of side effects far exceeded those felt by women), the news clearly struck a chord with many people who wish for the burden of birth control to be shared by men and women.
In 2014, Taryn O’Neill, Tamara Krinsky, and Gia Mora formed the Scirens, the screen sirens for science. Their mission is to inspire science literacy in the general public through entertainment fueled by science, technology, engineering, and mathematics (STEM) storylines and featuring, as they put it, “diverse, multi-dimensional female characters." The Signal to Noise Magazine had the opportunity to sit down with the Scirens and discuss their mission to encourage science literacy and create science-infused entertainment.
Every cell in an organism has unique functions which require specific proteins. For example, cells in eyes need proteins that can detect light, and immune cells use a variety of different proteins to detect and kill invading pathogens. To categorize each type of cell from a big group (say, from a blood sample, which contains many different cells), we can classify them based on their proteins. Now imagine you want to look at many different proteins on a lot of individual cells, and you want to do it fast. How can a scientist analyze almost twenty proteins on each cell, from millions of single cells, in less than an hour? This isn’t the imaginary dream of a tired graduate student, or a magical machine available only to the richest labs—this is flow cytometry.
Can you imagine a trip to the dentist to treat a cavity that didn’t involve a filling, a root canal or dentures? What if there was a way that we could encourage your teeth to repair themselves? ‘Stem cell dentistry’ could revolutionize your future trips to the dreaded dentist’s chair after recent scientific breakthroughs – regenerative stem cell fillings and growing new teeth from scratch using stem cells!
