Rapidly increasing data traffic is placing ever greater demands on the capacity of communication systems. In an article titled “Ultra-broadband optical amplification using nonlinear integrated waveguides” published in Nature, a research team from Chalmers University of Technology, in Sweden, introduce a new amplifier that enables the transmission of 10 times more data per second than those of current fiber-optic systems.

This amplifier, which fits on a small chip, holds significant potential for various critical laser systems, including those used in medical diagnostics and treatment.

The advancement of AI technology, the growing popularity of streaming services, and the proliferation of new smart devices are among the factors driving the expected doubling of data traffic by 2030. This surge is heightening the demand for communication systems capable of managing vast amounts of information.

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers at the University of Tsukuba have derived an equation describing this phenomenon, demonstrating that beyond liquid viscosity and compressibility, variations in tube cross-sectional area contribute to wave attenuation.

Their analysis reveals that the rate of change in tube cross-sectional area represents a critical parameter governing pressure wave attenuation in such systems.

Pressure waves propagating through bubble-containing liquids in , known as “bubbly ,” behave distinctly from those in single-phase liquids, necessitating precise understanding and control of their propagation processes.

A vivid digital reconstruction has brought to life the face of a Mycenaean woman who lived over 3,500 years ago, offering an unusually poignant glimpse into the world of ancient Greece, from long before the time of Homer or the Trojan War.

This ambitious project was launched at the initiative of Dr. Emily Hauser, a historian and lecturer in Classical Studies at the University of Exeter. The final image, she said, was both “incredibly exciting” and “unexpectedly modern.”

“For the first time, we are looking into the face of a woman from a kingdom associated with Helen of Troy —Helen’s sister, Clytemnestra, was queen of Mycenae in legend—and from where the poet imagined the Greeks of the Trojan War setting out,” Dr. Hauser explained in an interview published in the Daily Mail.
