The metalaser’s beam pattern can be shaped arbitrarily and has low levels of laser-intensity fluctuations known as speckle noise.

Photonic memristor arrays fabricated from hexagonal boron nitride/silicon heterostructures provide a scalable, silicon-compatible solution for artificial vision systems, featuring broad spectral reconfigurability and promising performance characteristics.

Starfront’s remote observatory lets customers aim their scopes at the cosmos from anywhere.

The feathers can emit two frequencies of laser light from multiple regions across their colored eyespots.

According to conventional wisdom, Einstein’s Theory of Relativity showed that the flow of time is an illusion, and that reality is a fixed block. And philosophers from Augustine to McTaggart have found the idea of time’s passage to be incoherent. However, argues James Sares, the idea that time’s flow is an illusion is itself incoherent.

With the discovery of yet another sense, this time in our guts, we’re starting to lose count.

The system is the first ever fully passive megawatt-hour scale battery storage system, and the first grid-scale sodium-ion storage solution ever deployed to the U.S. electric grid.

Caltech scientists have developed a method to create metallic objects of a precisely specified shape and composition, giving them unprecedented control of the metallic mixtures, or alloys, they create and the enhanced properties those creations will display. Want a stent that is biocompatible and mechanically robust? How about strong but lightweight satellite components that can operate in space for decades?
