Warming up optoelectronic research for new generation of optoelectronic devices

more »
A team of physicists is creating tailor-made materials for cutting-edge research and perhaps a new generation of optoelectronic devices. The materials make it easier for the researchers to manipulate excitons, which are pairs of an electron and an electron hole bound to each other by an electrostatic force.

The expansion of the Universe simulated

more »
The universe is constantly expanding. But how does our universe evolve? Physicists have now developed a new code of numerical simulations that offers a glimpse of the complex process of the formation of structures in the universe. Based on Einstein's equations, they were able to integrate the rotation of space-time into their calculations and calculate the amplitude of gravitational waves.

Mercury's mysterious 'darkness' revealed

more »
Scientists have long been puzzled by Mercury's very dark surface. Previously, scientists proposed that the darkness came from carbon accumulated by comet impacts. Now scientists confirm that carbon is present at Mercury's surface, but that it most likely originated deep below the surface, in the form of a now-disrupted and buried ancient graphite-rich crust, which was later brought to the surface via impacts after most of the current crust formed.

The properties of light can be controlled by means of nanostructures

more »
A theoretical study based on computational simulations has shown that the intensity of ultraviolet light that is made to pass through a graphene nano-ribbon is modulated with a terahertz frequency. So we are seeing the opening up of a new field of research into obtaining terahertz radiation that has a whole host of applications.

Explosive start not needed for fast radio bursts

After combing through archived data, astronomers have discovered the pop-pop-pop of a mysterious, cosmic Gatling gun -- 10 millisecond-long "fast radio bursts" -- recently caught by the Arecibo telescope in Puerto Rico.

NASA Goddard network maintains communications from space to ground

more »
Spending nearly a year in space, 249 miles from Earth, could be a lonely prospect, but an office at NASA's Goddard Space Flight Center in Greenbelt, Md., made sure astronaut Scott Kelly could reach home for the entire 340-day duration of his mission. Not only could Kelly communicate with mission control in Houston, but Goddard's Network Integration Center connected him with reporters and even family.
