Using artificial intelligence to understand volcanic eruptions from tiny ash
Scientists have shown that an artificial intelligence program called a Convolutional Neural Network can be trained to categorize volcanic ash particle shapes. Because the shapes of volcanic particles are linked to the type of volcanic eruption, this categorization can help provide information on eruptions and aid volcanic hazard mitigation efforts.

Path to zero emissions starts out easy, but gets steep
Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change. This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new article.

Atomic movie of melting gold could help design materials for future fusion reactors
Researchers have recorded the most detailed atomic movie of gold melting after being blasted by laser light. The insights they gained into how metals liquefy have potential to aid the development of fusion power reactors, steel processing plants, spacecraft and other applications where materials have to withstand extreme conditions for long periods of time.

Injectable electronics offer powerful new tool in understanding how retinal cells work
For decades, scientists hoping to understand how the retina interprets visual input have often had to resort to invasive techniques to dissect the retina from the animal in an effort to record the cells' activity, but a new system could make it possible to track the firing patterns of dozens of cells chronically in awake animals.

Light mixer generates 11 colors simultaneously
A multicolor laser pointer you can use to change the color of the laser with a button click -- similar to a multicolor ballpoint pen -- is one step closer to reality thanks to a new tiny synthetic material.

Mars dust storm may lead to new weather discoveries
Mars is experiencing an estimated 15.8-million-square-mile dust storm, roughly the size of North and South America. This storm may not be good news for the NASA solar-powered Opportunity rover, but one professor sees this as a chance to learn more about Martian weather.

Spectral cloaking could make objects invisible under realistic conditions
Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the manipulation of the frequency (color) of light waves as they pass through an object, a fundamentally new approach that overcomes critical shortcomings of existing cloaking technologies.

Nanoaggregation on command
A combination of natural microtubules and synthetic macrocyclic receptors allows for the light-controlled, reversible aggregation of the microtubules into larger nanostructures. When in a cellular environment these aggregated microtubules can also change cell morphology, causing cell death. Researchers hope to learn more about diseases caused by the improper aggregation of proteins.
