High-quality microwave signals generated from tiny photonic chip
In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it could fit on a sharp pencil.....»»
NASA, industry improve lidars for exploration, science
NASA engineers will test a suite of new laser technologies from an aircraft this summer for Earth science remote sensing. Called "lidar," the instruments could also be used to improve models of the moon's shape and aid the search for Artemis landing.....»»
Scientists Are Tinkering With Clouds to Save the Great Barrier Reef
Super-reflective clouds could shelter coral from scorching sunlight. But environmentalists are concerned that such plans could prolong our addiction to fossil fuels......»»
The Super Mario Maker community faces its final boss

Supercomputer simulations of super-diamond suggest a path to its creation
Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth......»»
Researchers develop novel "super-tetragonal" sacrificial layer for freestanding oxide membranes
Researchers have developed a new water-soluble sacrificial layer, "super-tectragonal" Sr4Al2O7 (SAOT), with broad tunability in lattice constants, which can be used to prepare high-quality freestanding oxide membrane. Their work is published in Scien.....»»
Holographic message encoded in simple plastic
There are many ways to store data—digitally, on a hard disk, or using analog storage technology, for example as a hologram. In most cases, it is technically quite complicated to create a hologram: High-precision laser technology is normally used fo.....»»
Better kombucha brewing through chemistry
Kombucha is a fermented tea known for its health benefits and tangy kick. But brewers can find it challenging to keep kombucha's alcohol levels low because the bacteria and yeast used in the fermentation process vary from batch to batch......»»
Not just a lodger: Novel host-guest assembly provides enhanced reactivity
By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical str.....»»
Direct laser writing on halide perovskites: From mechanisms to applications
Metal halide perovskites have become well-deserved "star" materials among a variety of semiconductors owing to their excellent optoelectronic properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable ban.....»»
Advances and challenges in understanding compound weather and climate extremes
In the context of global warming, many extremes, such as heat waves, heavy precipitation, and droughts, have become increasingly frequent and intense, as expected theoretically. Somewhat unexpectedly, these extremes have also exhibited tightened link.....»»
SpaceX"s 3rd Starship launch makes it to space without exploding, but is lost on reentry
SpaceX's powerful Starship and Super Heavy rocket completed a more successful third orbital test flight from Texas on Thursday morning with no explosive endings on the way up that marred the first two test flights in 2023......»»
Facts about hail, the icy precipitation often encountered in spring and summer
Intense storms swept through Kansas and Missouri on Wednesday and brought whipping winds, possible tornadoes, and what some described as "gorilla hail.".....»»
Quantum dance to the beat of a drum: Researchers observe how energy of single electron is tuned by surrounding atoms
Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second......»»
