- 			 Astronomy AstronomyGalaxy’s cloud catalog reveals hydrogen fogFifty percent of the molecular hydrogen exists in a gas layer that spreads throughout the Whirlpool galaxy and envelopes the giant clouds where stars form. 
- 			 Health & Medicine Health & MedicineWatching media coverage of disasters linked to stressWatching hours of media coverage of traumatic events may worsen symptoms of distress. 
- 			 Life LifeH7N9 flu still better adapted to infect birds over humansThe proteins from the avian flu appear better suited for attaching to bird, not human, molecules. 
- 			 Life LifeTargeting single set of nerve cells may block mosquitoesThe insects use the same neurons to detect carbon dioxide from our breath and odors from our skin so blocking those cells could lead to more simplified repellent systems. 
- 			 Neuroscience NeuroscienceExcess activity shrinks blood vessels in baby mouse brainsNewborn mouse pups experience permanent brain changes when repeatedly overstimulated. 
- 			 Health & Medicine Health & MedicineForecasting system predicts peaks in flu outbreaksA real-time forecasting system has accurately predicted the peak flu cases up to nine weeks before the outbreak. 
- 			 Planetary Science Planetary ScienceChina’s first moon-landing mission blasts offIf successful, the Chang’e 3 lunar lander and Yutu rover will be the first spacecraft to land on the moon in 37 years. 
- 			 Planetary Science Planetary ScienceTurbulent ocean could explain Europa’s chaotic iceNew computer simulations show turbulent global ocean currents that distribute heat unevenly and could explain the formation of the chaotic ice patterns at the moon’s lower latitudes. 
- 			 Psychology PsychologyGut reaction could foretell marriage satisfactionUnconscious gut reactions may predict happy, and not-so-happy, marriages, a new study suggests.
