Silk Fibers May Represent Natural Metamaterials, Capable of light Confinement
New research has demonstrated how the nano-architecture of a silkworm’s fiber causes “Anderson localization of light,” a discovery that could lead to various innovations and…
Breathtaking Hubble Image of Spiral Galaxy NGC 7331
This NASA/ESA Hubble Space Telescope image shows a spiral galaxy known as NGC 7331. First spotted by the prolific galaxy hunter William Herschel in 1784,…
Meteorites Were Byproducts of Planetary Formation, Not Building Blocks
A newly published study from researchers at MIT and Purdue University reveals that chondrules were byproducts of a violent and messy planetary process, not building…
Researchers Demonstrate the Scalability of Quantum Dot Architectures
New research from the RIKEN Center for Emergent Matter Science reveals how arrays of electrons trapped in nanoscale circuitry could form the basis for future…
Metal-Dielectric Epitaxial Superlattice Brings ‘Hyperbolic Metamaterials’ Closer to Reality
Researchers from Purdue University have created superlattices from layers of metal titanium nitride and aluminum scandium nitride, bringing “hyperbolic metamaterials” closer to reality. West Lafayette,…
Astronomers View a Rare Multiple Quasar Imaging Event Caused by a Gas Cloud
Scientists view a rare multiple quasar imaging event caused by the effects of a cloud of ionized gas in the Milky Way Galaxy. For the…
GRAIL Data Helps Solve Mystery of Moon’s Uneven Surface Gravity
By combining GRAIL gravity data with computer models of large asteroid impacts and known details about the geologic evolution of impact craters, scientists were able…
Phobos May Provide Evidence of Life on Mars
Scientists estimated that several large impact events on Mars could have launched significant amounts of Martian material into space, leading them to believe that if…
Tiny “Spherules” Record Precise Information About Asteroid Impacts on Earth
A new method for extracting precise information from tiny “spherules” embedded in layers of rock has allowed researchers to record precise information about asteroids impacting…
New Metamaterial Uses “Aluminum-Doped Zinc Oxide” for Enhanced Performance
By using an “aluminum-doped zinc oxide,” or AZO, Purdue researchers have shown how to create metamaterials without using silver or gold. The new metamaterial consists…
