Sometimes, when experimental scientists get their hands on a supercomputer, it can change the course of their careers and open up new questions for exploration. This was the case with Abdurrahman and Tülay Atesin, husband and wife chemists, collaborators...
Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to...
When two Sun-like stars collide, the result can be a spectacular explosion and the formation of an entirely new star. One such event was seen from Earth in 1670. It appeared to observers as a bright, red "new...
This summer, humanity embarks on its first mission to touch the Sun: A spacecraft will be launched into the Sun's outer atmosphere. Facing several-million-degree Fahrenheit temperatures, NASA's Parker Solar Probe -- named after Eugene Parker, the University of Chicago...
Replacing traditional computer chip components with light-based counterparts will eventually make electronic devices faster due to the wide bandwidth of light. A new protective metamaterial "cladding" prevents light from leaking out of the very curvy pathways it would travel...
Computer vision algorithms have come a long way in the past decade. They've been shown to be as good or better than people at tasks like categorizing dog or cat breeds, and they have the remarkable ability to...
A new way of arranging advanced computer components called memristors on a chip could enable them to be used for general computing, which could cut energy consumption by a factor of 100. This would improve performance in low power...
Lithium metal batteries hold tremendous promise for next-generation energy storage because the lithium metal negative electrode has 10 times more theoretical specific capacity than the graphite electrode used in commercial Li-ion batteries. It also has the most negative...
Our daily lives rely on electronic processors, which perform the basic arithmetic, logical, and control operations that make devices from mobile phones to smart TVs possible. Current technologies are, however, approaching their limits and researchers around the world...
As environmental and energy issues have become increasingly aggravated in recent years, photovoltaic (PV) cells are drawing attention as a new energy source. However, since the cost of silicon PV cells is still high, it's important to reduce...
