Observation of Floquet solitons in a topological bandgap
Topological protection is a universal phenomenon that applies to electronic, photonic, ultracold atomic, mechanical, and other systems. The vast majority of research in these systems has explored the linear domain,...
Aligned, high-density semiconducting carbon nanotube arrays for high-performance electronics
Single-walled carbon nanotubes (CNTs) may enable the fabrication of integrated circuits smaller than 10 nanometers, but this would require scalable production of dense and electronically pure semiconducting nanotube arrays on...
Free agent QB Cam Newton shows zip on throws, smooth drop back
Free agent Cam Newton showed off his throwing power and fluid drop-back motion in a video posted to Instagram, as the quarterback hopes to sign with an NFL team before...
Huntington Ingalls lifts 320-ton deckhouse onto USS Jack H. Lucas
Huntington Ingalls Shipbuilding division lifted the 320-ton aft deckhouse onto the guided missile destroyer Jack H. Lucas, also known as DDG 125, this week.
Scientists boost microwave signal stability a hundredfold
Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability...
VR and AR devices at 1/100 the cost and 1/10,000 the thickness in the works
Mechanical and chemical engineers have developed moldable nanomaterials and a printing technology using metamaterials, which allows for the commercialization of inexpensive and thin VR and AR devices.
'One-way' electronic devices enter the mainstream
Engineers are the first to build a high-performance non-reciprocal device on a compact chip with a performance 25 times better than previous work. The new chip, which can handle several...
Study unveils details of how a widely used catalyst splits water
A crystalline compound called ruthenium dioxide is widely used in industrial processes, where it’s particularly important for catalyzing a chemical reaction that splits molecules of water and releases oxygen. But the exact mechanism...
When will the heat wave end?
Meteorologist Jeff Berardelli joins "CBS Weekend News" with more on the stifling heat wave striking the central and eastern U.S.
Laser-based technique captures 3D images of impressionist-style brushstrokes
Researchers have developed a new strategy that uses optical coherence tomography (OCT) to acquire both the surface and underlying details of impressionist style oil paintings. This information can be used...
The self-synthesizing ribosome
As the cell's protein factory, the ribosome is the only natural machine that manufactures its own parts. That is why understanding how the machine, itself, is made, could unlock the...
A new understanding of everyday cellular processes
We use cells to breathe, to moderate body temperature, to grow and many other every day processes, however the cells in these processes are so complex its left scientists perplexed...
Quantum leap: Photon discovery is a major step toward at-scale quantum technologies
