Watching water droplets merge on the International Space Station      (via sciencedaily.com) 

Researchers design and analyze droplet experiments that were done on the International Space Station. The researchers sent four different surfaces with various roughness properties to the station, where they were mounted to a lab table. Cameras recorded the droplets as they spread and merged. The experimental results confirmed and expanded the parameter space of the Davis-Hocking model, a simple way to simulate droplets.

First ultraviolet imaging of Sun's middle corona      (via sciencedaily.com) 

Researchers have discovered web-like plasma structures in the Sun's middle corona. The researchers describe their innovative new observation method, imaging the middled corona in ultraviolet (UV) wavelength. The findings could lead to a better understanding of the solar wind's origins and its interactions with the rest of the solar system.

Antihelium nuclei as messengers from the depths of the galaxy      (via sciencedaily.com) 

How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team has now measured the survival rate of antihelium nuclei from the depths of the galaxy -- a necessary prerequisite for the indirect search for Dark Matter.

Peekaboo! Tiny, hidden galaxy provides a peek into the past      (via sciencedaily.com) 

Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years across, the tiny galaxy HIPASS J1131-31 has been nicknamed "Peekaboo" because of its emergence in the past 50-100 years from behind the fast-moving star that was obscuring astronomers' ability to detect it.

Giant mantle plume reveals Mars is more active than previously thought      (via sciencedaily.com) 

Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. The discovery reveals that Mars, like Earth and Venus, possesses an active interior, which challenges current views on the evolution of the red planet.

Microlaser chip adds new dimensions to quantum communication      (via sciencedaily.com) 

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.

Trial by wind: Testing the heat resistance of carbon fiber-reinforced ultra-high-temperature ceramic matrix composites      (via sciencedaily.com) 

Carbon fiber-reinforced ultra-high-temperature ceramic (UHTC) matrix composites are extensively used in space shuttles and high-speed vehicles. However, these composites suffer from a lack of oxidation resistance. Recently, researchers tested the heat resistance of these composites at very high temperatures, providing insight into the modifications needed to prevent UHTC degradation. Their findings could have huge implications for the manufacture of space shuttle orbiters.

Exploring the possibility of extraterrestrial life living in caves      (via sciencedaily.com) 

For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.

Safety in space: Synthetic hibernation could provide protection from cosmic radiation      (via sciencedaily.com) 

It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising approaches to follow up such considerations. An international research team now has found decisive indications of the possible benefits of artificial hibernation for radiation resistance.

Improving the performance of electrodeless plasma thrusters for space propulsion      (via sciencedaily.com) 

Space missions already use electric propulsion devices, where electromagnetic fields are utilized to generate the thrust of spacecraft. One such electrodeless device, which harnesses radio frequency (rf) to generate plasma and a magnetic nozzle (MN) to channel and accelerate plasma, has shown immense promise in pushing the boundaries of space travel. But scientists have so far failed to achieve efficient conversion of the rf power to thrust energy. Now, a researcher has achieved a stunning 30% conversion efficiency.
