Ten years ago, researchers succeeded in suppressing sound wave propagation in the backward direction; however, this also attenuated the waves traveling forwards.

A team of researchers at ETH Zurich led by Nicolas Noiray, professor for Combustion, Acoustics and Flow Physics, in collaboration with Romain Fleury at EPFL, has now developed a method for preventing sound waves from traveling backward without deteriorating their propagation in the forward direction.

In the future, this method, which has recently been published in Nature Communications, could also be applied to electromagnetic waves.

1 or 2? Is Roger Penrose’s theory of three worlds the result of Penrose’s understanding of the physical world? 1. understands it correctly or 2. misunderstands it? — You can find explanations e.g. under the following link:

Es gibt praktische Fragen, die mit unseren konkreten Leben zu tun haben, und theoretische Fragen, die damit scheinbar nichts zu tun haben. Es gibt aber auch theoretische Überlegungen, die durchaus mit unserem praktischen Alltag zu tun haben. Eine davon ist die Drei-Welten-Theorie, die sich damit beschäftigt, in welchen Welten wir konkret leben.

Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate with one another using a language made up of molecules and proteins.

A study by the Medical University of Vienna has made important progress in understanding heat perception in humans. The research team was able to identify a specific cell structure that plays a role in recognizing heat. However, most of the protective recognition of heat in everyday life depends on other, as yet unknown structures.

What if it were possible to generate tissues and cells that replicate the functions of human organs, and then use them to study and treat human conditions?

Upon ultrafast photoexcitation, an all-dielectric nonlocal metasurface enables giant dichroism and birefringence modulations, working as a quarter-waveplate actively reconfigurable over picoseconds.
