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.

In this extended color image of Pluto taken by NASA’s New Horizons spacecraft, rounded and bizarrely textured mountains, named the Tartarus Dorsa, rise up along Pluto’s day-night terminator and show intricate but puzzling patterns of blue-gray ridges and reddish material in between. This view, roughly 330 miles (530 km) across, combines blue, red and infrared images taken by New Horizons’ Ralph/Multispectral Visual Imaging Camera on July 14, 2015.

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.
