When a star gets too close to a supermassive black hole (SMBH), the star’s fate is sealed. The SMBH’s gravity is overwhelming, and as the star is drawn toward the hole, it is stretched out and ...

Optical spectroscopy techniques are used in physics, astronomy, chemistry, biology, and associated research fields.

Known for their ability to seamlessly integrate into semiconductor chips, VCSELs (vertical cavity surface-emitting lasers) ...

A new theory-guided framework could help scientists probe the properties of new semiconductors for next-generation ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution ...

This useful study employs optogenetics, genetically-encoded dopamine and serotonin sensors, and patch-clamp electrophysiology to investigate modulations of neurotransmitter release between striatal ...

This paper reviews techniques for determining B concentration and isotopie ratio and their application to soil and plant samples. Boron concentration has been determined utilising spectrophotometry, ...

The researchers calculated that global aviation hubs like New York City's JFK International Airport and London, England's Heathrow and Gatwick could be serving as "technosignatures"—or clues to our ...
