Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical setups and interference ...
For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing.
Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and pollutants with extremely high ...
While nothing says "summer" quite like the taste of a perfectly ripe tomato, excessive heat during the growing season can prevent tomato plants from bearing fruit.
Solitonic waves—waves that keep their shape and direction of motion for a long time—have intrigued physicists for almost two centuries. In real-world circumstances, these waves eventually die out due to energy loss. A ...
Lava shoots high into the sky. Molten rock erupts from two vents simultaneously. The nighttime sky glows red and orange, reflecting the lava oozing across a summit crater.
Simulations still can't predict exactly when an earthquake will happen, but with the incredible processing power of modern exascale supercomputers, they can now predict how they will happen and how much damage they will likely ...
Hurricane Erin's massive footprint battered Caribbean islands with heavy gusts and downpours Monday, as it threatened rip currents and flooding along the US East Coast later this week even without a predicted landfall.
A team of international researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Johns Hopkins University and Duke University has discovered that a century-old theory describing turbulence in fluids also applies ...
Biomedical engineers at Duke University have developed a method to more precisely heat up gold nanoparticles to target and destroy cancerous tumors. Using imaging methods that combine light and sound to peer deeper into tissue, ...
