Our bodies are picky eaters when it comes to amino acids, and sometimes just a small screw-up can cause larger problems down the road. Scientists recently found an association between an amino-acid depleting mutation, and neurological problems in a small sample of humans. In mice with the same mutation, nutritional supplements reversed similar symptoms, offering the possibility of a treatment for the human disorder in the future. The results appeared in the journal ScienceRead More

Titan, which is larger than Mercury, boasts a thick atmosphere of mostly nitrogen with dashes of methane, carbon monoxide, and other trace ingredients (At -290 degrees Fahrenheit, Titan is a tad too frigid for liquid water). Horst brewed up an approximation of that mixture. She and her colleagues then blasted it with radio-frequency radiation, a lab stand-in for ultraviolet radiation from the sun.
