Terahertz light from superconducting lines

Excessive-temperature superconducting coppers emit THz radiation as soon as their floor is illuminated with ultrashort gentle pulses. This impact happens solely in compounds during which superconductivity coexists with the order of the cost band. Credit score: Jörg Harms, MPSD Why do some supplies carry electrical currents with none resistance solely when cooled to close absolute … Read more

How the effort to reduce the use of fossil fuels has led to light pollution

Los Angeles In 2014, Los Angeles decreased annual carbon emissions by 43% and saved $9 million in power prices by changing the bulbs in additional than half of metropolis avenue lights with LEDs. That 12 months, the Nobel Prize in Physics was awarded to 3 scientists whose work made these lamps potential. When saying the … Read more

Credit score: Satoshi Kaya / Flickr Scientists who’ve delved deeper into an undersea earthquake fault than ever earlier than have discovered that tectonic stress in Japan’s Nankai subduction zone is decrease than anticipated, in … Read more

Differentiate between left and right particles using the force exerted by light

Scanning electron microscope pictures present D and L-shaped gold nanoparticles. The interiors depict the 3D fashions of the nanoparticles. Credit score: NINS/IMS The researchers investigated the polarization dependence of the power exerted by circularly polarized mild (CPL) by performing optical trapping of chiral nanoparticles. They discovered that the left and proper CPL exert completely different … Read more

Overtime: to light a pest or is it okay? Startups are divided over their opinions

The additional time controversy – which lately sparked sturdy reactions from a few of India’s prime IT chiefs – has unfold to the startup sector, which is clearly divided on the difficulty. In terms of side-job workers, the overall feeling is to tread rigorously, and I’ve discovered ET primarily based on conversations with a number … Read more

How an effort to reduce fossil fuel use led to another environmental problem: light pollution

In 2014, Los Angeles lowered annual carbon emissions by 43% and saved $9 million in vitality prices by changing the bulbs in additional than half of metropolis road lights with LEDs. That yr, the Nobel Prize in Physics was awarded to 3 scientists whose work made these lamps attainable. When saying the award, the Nobel … Read more

Quantum light source improves the clarity of bio-imaging

Enhanced quantitative microscopy utilizing water as a sign medium. The imaging object is a triangle-shaped piece of glass proven in inset (a), the place the white scale bar is 1 mm within the horizontal path. Greater than 3 dB quantitative enhanced SNR, or picture distinction, is clearly seen in (b). attributed to him: optics (2022). … Read more

Compact electron accelerator reaches new speeds with nothing but light

A picture from a simulation during which a laser pulse (purple) drives a plasma wave, accelerating electrons in its wake. The intense yellow spot is the area with the best focus of electrons. In a single experiment, scientists used this method to speed up electrons to just about the velocity of sunshine over a spread … Read more
