The receptors required for the gustatory responses to sour compounds have been elusive. Rimal et al discover a Drosophila taste receptor, IR7a, which is required for rejecting a sour chemical. Surprisingly, IR7a is narrowly tuned to acetic acid, suggesting that carboxylic acids are detected by a repertoire of receptors. Image credit: Rimal et al, doi: 10.1016/j.celrep.2019.01.042.

In conventional electronic devices, electricity requires the movement of electrons (blue spheres) and their positive counterparts, called holes (red spheres), which behave much like the gas molecules in our atmosphere. Although they move rapidly and collide infrequently in the gas phase, electrons and holes can condense into liquid droplets akin to liquid water in devices composed of ultrathin materials.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.
