Searching the Universe May Now Be A Lot Easier. Looking up at the night sky so expansive and seemingly endless, stars and constellations blinking and glimmering like jewels just out of reach one finds that it is impossible not to wonder: Are we alone?

In the quest to harvest light for electronics, the focal point is the moment when photons or light particles encounter electrons, those negatively-charged subatomic particles that form the basis of our modern electronic lives. If conditions are right when electrons and photons meet, an exchange of energy can occur.

The Violent Conditions Of The Universe. Conditions in the vast universe can be quite extreme: Violent collisions scar the surfaces of planets. Nuclear reactions in bright stars generate tremendous amounts of energy. Gigantic explosions catapult matter far out into space. But how exactly do processes like these unfold? What do they tell us about the […]

The Search For Evidence of Cosmological Inflation. Now that scientists have confirmed the existence of gravitational waves, a NASA team is set to search for a predicted signature of primordial gravitational waves that would prove the infant universe expanded far faster than the speed of light and began growing exponentially almost instantaneously after the Big […]

Is There A New State of Matter? An international team of researchers have found evidence of a mysterious new state of matter, first predicted 40 years ago, in a real material. This state, known as a quantum spin liquid, causes electrons which are thought to be indivisible building blocks of nature, to break into pieces.

Why Do We Need A Next Generation Of Terahertz Systems? In physics, terahertz radiation refers to electromagnetic waves propagating at frequencies in the terahertz range.The term typically applies to electromagnetic radiation with frequencies between high-frequency edge of the microwave band, 300 gigahertz (3×1011 Hz), and the long-wavelength edge of far-infrared light, 3000 GHz (3×1012 Hz or […]
