Nanoparticles of certain metals, like gold or silver, have attracted substantial interest in recent years owing to their ability to support localized surface plasmon resonances (collective oscillations of conduction electrons). These plasmonic excitations allow manipulation of light at the nanoscale and have enabled technological advances ranging from improved catalytic and photovoltaic cell efficiencies to sensitive […]

A phase may be defined as a homogeneous portion of a system that has uniform physical and chemical characteristics. Every pure material is considered to be a phase; so also is every solid, liquid, and gaseous solution. For example, a sugar–water syrup solution is one phase, and solid sugar is another. Each has different physical […]

Neanderthal Y chromosome missing in modern humans The Neanderthal Y chromosome hasn’t been found in modern humans, suggesting it is extinct. Researchers found dissimilarities in the Neanderthal Y chromosome’s immunity genes that could have caused miscarriages. BBC Clouds may not help keep global temperatures down Clouds’ cooling power may not be as great as climate […]

Photos reveal possible planet-forming disk around young star Photos taken by the Atacama Large Millimeter/submillimeter Array, or ALMA, appear to show the birth of an alien planet similar to Earth along with other nascent worlds. The photos reveal a disk surrounding the star TW Hydrae that appears to have planets starting to form within it […]
