Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
Study: Giant ultrafast dichroism and birefringence with active nonlocal metasurfaces
The fine and efficient control of the properties of light at ultrafast speed down to the picosecond timescale is a challenging task, crucial for many scientific applications and technologies. For instance, in free-space optical links, manipulating on.....»»
Research explores whether "everything as a service" will live up to its great expectations
It's no secret that the composition of the American economy is changing. As the manufacturing sector continues to decline, the balance is slowly tipping even further away from goods and towards services. In line with this larger trend, many firms hav.....»»
The world"s fastest single-shot 2D imaging technique films ultrafast dynamics in flames
Candle flames and airplane engines produce tiny soot particles from polycyclic aromatic hydrocarbons (PAHs) as their precursors, both of which are harmful to humans and the environment. These carbon-based particles are also common in space, making up.....»»
High-refractive-index-modulation nanocomposites for augmented reality displays
Holographic optical elements (HOEs) are essential in augmented reality (AR) displays, providing benefits such as design flexibility and improved optical efficiency. However, current materials' limited refractive index modulation hampers performance,.....»»

Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»
Yosemite National Park: Crews restore damaged landscape back to conditions not seen in 150 years
Yosemite National Park is famous for towering waterfalls, giant sequoia trees and massive granite cliffs. But at an out-of-the-way spot near the park's western boundary few visitors ever see, a landmark of a different type is taking shape......»»
Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed
When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It's also bad for human populations that rely on fish for protein in their diets......»»
