The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. The colors in the spectra show dips, the size of which reveal the amount of these elements in the atmosphere of a star. The human body on the left uses the same color coding to evoke the important role these elements play in different parts of our bodies, from oxygen in our lungs to phosphorous in our bones (although in reality all elements are found all across the body). In the background is an artist’s impression of the Galaxy, with cyan dots to show the APOGEE measurements of the oxygen abundance in different stars; brighter dots indicate higher oxygen abundance.

This illustration shows several comets speeding across a vast protoplanetary disk of gas and dust and heading straight for the youthful, central star HD 172555. These exocomets will eventually plunge into the star and vaporize. HD 172555 represents the third extrasolar system where astronomers have detected doomed, wayward comets. All of the systems are young, under 40 million years old. Image credit: NASA / ESA / A. Feild & G. Bacon, STScI.

Stephanie M. Reeve et al. identified two plasmid-borne genes that confer high-level resistance to trimethoprim for the first time in MRSA isolates from U.S. hospitals; a series of charged propargyl-linked antifolates overcome this resistance via direct inhibition of the acquired resistance elements. This colorized scanning electron micrograph depicts a grouping of MRSA bacteria. These bacteria are methicillin-resistant, and are from one of the first isolates in the U.S. that showed increased resistance to vancomycin as well. Note the increase in cell wall material seen as clumps on the organisms’ surface. Image credit: Janice Haney Carr / Public Health Image Library / CDC.
