Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have for the first time been able to prove a long-predicted but as yet unconfirmed fundamental effect. In Faraday chiral anisotropy, the propagation characteristics of light waves are changed simultaneously by the natural and magnetic-field induced material properties of the medium through which the light travels. The researchers obtained proof that this is the case by conducting experiments using nickel helices at the nanometre scale. Their findings have now been published in the academic journal Physical Review Letters .
Light is transmitted as sine waves consisting of crossed electric and magnetic fields and interacts with matter. This interaction can be influenced, in particular, by external magnetic fields. One of the most well-known examples of this magneto-optical activity is the Faraday effect: if light is directed through a magnetic medium, such as a crystal, the polarisation plane of the l
Scientists model Saturn s interior, explain planet s unique magnetic field
It is notoriously difficult to study the interior structures of large gaseous planets, and the findings advance the effort to map Saturn s hidden regions.
Washington: New Johns Hopkins University simulations offer an intriguing look into Saturn s interior, suggesting that a thick layer of helium rain influences the planet s magnetic field.
The models, published in the journal AGU Advances, also indicate that Saturn s interior may feature higher temperatures at the equatorial region, with lower temperatures at the high latitudes at the top of the helium rain layer.

Washington [US], May 6 (ANI): New Johns Hopkins University simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.
China is building a laser that can produce 100 quadrillion watts – about 50,000 times the planet’s total power consumption a light so intense that it would equal the amount of power our Earth receives from the Sun.
Station of Extreme Light
At the heart of the Shanghai Superintense Ultrafast Laser Facility (SULF), due to go online in 2025,is a single cylinder of titanium-doped sapphire about the width of a Frisbee. After kindling light in the crystal and shunting it through a system of lenses and mirrors, the SULF distills it into pulses of mind-boggling power, achieving an unprecedented 5.3 million billion watts, or petawatts (PW), reported Science.
