Male birth control for the malaria parasite
Fluorescent staining of the CAF1/CCR4/NOT complex in the malaria parasite. This complex, which new research shows is important for RNA stability and the maturation of the male sexual form of the malaria parasite, is found as granules (green) throughout the cytosol of the malaria parasite.

Stellar winds, the source material for the universe, are clumpy
Illustration of a high-mass X-ray binary system made up of a compact, incredibly dense neutron star paired with a massive normal supergiant star. New data from NASAs Chandra X-ray Observatory shows that the neutron star in the high-mass X-ray binary, OAO 1657-415, passed through a dense patch of stellar wind from its companion star, demonstrating the clumpy nature of stellar winds.

New method uses ultraviolet light to control fluid flow and organize particles
A new method uses ultraviolet light and small amounts of gold or titanium dioxide nanoparticles to gather larger particles at the point of light. This method was used to gather polystyrene particles, which form a well-packed structure called a colloid crystal, as depicted in this image. Credit: Sen Lab, Penn State

How hot are atoms in the shock wave of an exploding star?
An international team of researchers combined observations of nearby supernova SN1987A, made with NASA's Chandra X-Ray Observatory, with simulations to measure the temperature atoms in the shock wave that occurs from the explosive death of a star. This image superimposes synthetic X-ray emission data onto a density map with from the simulation of SN1987A.
