Teixobactin eliminates MRSA, Mycobacterium tuberculosis, Streptococcus pneumoniae, Bacillus anthracis and other dangerous pathogens without encountering any detectable resistance. This digitally-colorized, scanning electron microscopic image depicts green-colored, spheroid-shaped MRSA bacteria, as they were in the process of being enveloped by a much larger, human white blood cell.

When Comet 96P/Machholz appeared in SOHO’s view in 2012, astronomers discovered two tiny comet fragments some distance ahead of the main body, signaling the comet was actively changing. This time around they have detected a third fragment -- another breadcrumb in the trail that indicates 96P/Machholz is still evolving.

This graphic illustrates how water might be heated inside Enceladus. Over time, cool ocean water seeps into the moon’s porous core. Pockets of water reaching deep into the interior are warmed by contact with rock in the tidally heated interior and subsequently rise owing to the positive buoyancy, leading to further interaction with the rocks. The heat deposited at the boundary between the seafloor and ocean powers hydrothermal vents. Heat and rocky particles are transported through the ocean, triggering localized melting in the icy shell above. This leads to the formation of fissures, from which jets of water vapor and the rocky particles from the seafloor are ejected into space. In the graphic, the interior ‘slice’ is an excerpt from a new model that simulated this process. The orange glow represents the parts of the core where temperatures reach at least 194 degrees Fahrenheit. Tidal heating owing to the friction arising between particles in the porous core provides a key source of energy, but is not illustrated in this graphic. The tidal heating results primarily from the gravitational pull from Saturn.
