Fruit flies journey to International Space Station to study effects of zero gravity on the heart
Researchers have announced that six boxes of fruit flies (Drosophila melanogaster) will travel to the International Space Station (ISS) to study the impact of weightlessness on the heart. The fruit flies are scheduled to launch on June 1, 2017, from NASA’s Kennedy Space Center and will travel to the ISS via a SpaceX Dragon spacecraft.

Neptune: Neutralizer-free plasma propulsion
Plasma propulsion concepts are gridded-ion thrusters that accelerate and emit more positively charged particles than negatively charged ones. To enable the spacecraft to remain charge-neutral, a 'neutralizer' injects electrons to exactly balance the positive ion charge in the exhaust beam, but this neutralizer requires additional power from the spacecraft. Researchers are investigating how the radio-frequency self-bias effect can be used to remove the neutralizer altogether.

How radioactive decay could support extraterrestrial life
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn's moon Enceladus, Jupiter's moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.

A new approach to forecasting solar flares?
The emerging discipline of space meteorology aims to reliably predict solar flares so that we may better guard against their effects. Using 3D numerical models, an international team has discovered a proxy that could be used to forecast an eruptive event. The proxy is associated with magnetic helicity, which reflects the extent of twist and entanglement of the magnetic field.

History of Titan's landscape resembles that of Mars, not Earth
In a paper published in Science, researchers report that Titan, like Mars but unlike Earth, has not undergone any active plate tectonics in its recent past. The upheaval of mountains by plate tectonics deflects the paths that rivers take. The team found that this telltale signature was missing from river networks on Mars and Titan.

Waves of lava seen in Jupiter's moon Io's largest volcanic crater
The most active volcanic crater in the solar system, Loki Patera on Jupiter's moon Io, is thought to be a lava lake that periodically brightens because of overturning lava. A UC Berkeley team regularly monitors Io, and took advantage of a rare 2015 event, Europa passing in front of Io, to map the surface of the lake in detail. They found evidence for two massive waves of overturning lava converging toward the lake's southeast corner.

Why space dust emits radio waves upon crashing into a spacecraft
When spacecraft and satellites travel through space they encounter tiny, fast moving particles of space dust and debris. If the particle travels fast enough, its impact appears to create electromagnetic radiation that can damage or even disable the craft's electronic systems. A new study uses computer simulations to show that the cloud of plasma generated from the particle's impact is responsible for creating the damaging electromagnetic pulse.

Using math to investigate possibility of time travel
After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time.
