How complexity science can quickly detect climate record anomalies
The history of our climate is written in ice. Reading it is a matter of deciphering the complex signals pulled from tens of thousands of years of accumulated isotopes frozen miles below the surface of Antarctica.
Scientists dismiss the idea of travel through wormholes
A RUDN employee and Brazilian colleagues have called into question the concept of using stable wormholes as portals to different points of space-time. The results of the studies were published in Physical Review D.
When heat ceases to be a mystery, spintronics becomes more real
The development of spintronics depends on materials that guarantee control over the flow of magnetically polarized currents. However, it is hard to talk about control when the details of heat transport through the interfaces ...
It's not so easy to gain the true measure of things
I teach measurement – the quantification of things. Some people think this is the most objective of the sciences; just numbers and observations, or what many people call objective facts.
Using Wi-Fi signals to perform analog, wave-based computations
A pair of researchers, one with the Langevin Institute, the other a company called Greenerwave, both in France, has developed a way to use ordinary Wi-Fi signals to perform analog, wave-based computations. In their paper ...
Magic number colloidal clusters
Complexity in nature often results from self-assembly, and is considered particularly robust. Compact clusters of elemental particles can be shown to be of practical relevance, and are found in atomic nuclei, nanoparticles ...
The splendid generative potential of the Sierpinski triangle
One transistor can become an oscillator with a surprising richness of behavior. However, even more interesting effects emerge if the structure of connections is fractal and shows some imperfections. Could similar rules explain ...
Better superconductors from ceramic copper oxides
Medical magnetic resonance imaging, high-power microwave generators, superconducting magnetic energy storage units, and the solenoids in nuclear fusion reactors are very different technologies which all critically rely on ...
Good vibrations: Neutrons lend insight into acoustic fracking
Hydraulic fracturing contributes significantly to US energy production. It works by tapping hard-to-reach pockets of oil and natural gas where more traditional drilling methods fall short. However, the process requires large ...
