Fruit flies journey to International Space Station to study effects of zero gravity on the heart

more »
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.

Three-dimensional graphene: Experiment at BESSY II shows that optical properties are tuneable

more »
An international research team has for the first time investigated the optical properties of three-dimensional nanoporous graphene at the IRIS infrared beamline of the BESSY II electron storage ring. The experiments show that the plasmonic excitations (oscillations of the charge density) in this new material can be precisely controlled by the pore size and by introducing atomic impurities. This could facilitate the manufacture of highly sensitive chemical sensors.

Spiral Galaxy NGC 6744

more »
Big, beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo appearing as a faint, extended object in small telescopes. We see the disk of the nearby island universe tilted towards our line of sight. This remarkably distinct and detailed galaxy portrait covers an area about the angular size of the full moon. In it, the giant galaxy's yellowish core is dominated by the light from old, cool stars. Beyond the core, spiral arms filled with young blue star clusters and pinkish star forming regions sweep past a smaller satellite galaxy at the lower left, reminiscent of the Milky Way's satellite galaxy the Large Magellanic Cloud.
