Novel all-silicon metamaterials enhances control of terahertz polarization

Posted by in categories: biotech/medical, health

Researchers are working to unlock the immense potential of terahertz waves for applications ranging from medical imaging to wireless communications. However, efficiently controlling the polarization state of these high-frequency electromagnetic waves has remained an enduring challenge.

Conventional approaches relying on natural birefringent crystals or dielectric waveplates are hampered by narrow operational bandwidths, bulky hardware, and susceptibility to damage. These limitations have throttled progress towards commercially viable terahertz systems that fully exploit the information encoded in electromagnetic wave polarization.

Recent advances in metamaterials – artificial structures engineered with properties unattainable in nature – have brought fresh hope. Carefully designed metamaterial arrays allow researchers to overcome the constraints of natural materials and exercise unprecedented control over terahertz wave propagation.

Electric Bowl and Spoon Designed to Salten Foods Without Salt: Japan’s New Innovation

Posted by in categories: food, health

In the realm of culinary innovation, Japan has once again captured the spotlight with a groundbreaking invention. Imagine savoring your favorite low-sodium dishes, but with the rich salty flavor. This is no longer a fantasy, thanks to the ingenious creation of the ’ Electric Salt ’ bowl and spoon by scientists at Kirin Holdings Company and Meiji University in Japan (Figure 1).

Launched this year in Japan, the ‘Electric Salt’ devices are more than just ordinary kitchenware. They employ a subtle electrical stimulation, amplifying the salty taste of foods by an astonishing 1.5 times, all without the health drawbacks of high sodium intake. This revolutionary technology promises a new horizon for those mindful of their salt consumption, without sacrificing flavor.

This ingenious mechanism allows a minuscule electric current to pass through the food, enhancing the sodium ions’ journey to the diner’s taste buds. This process remarkably intensifies the salty flavor without any known impact on human health.

This ‘forbidden’ exoplanet is way too massive for its star

Posted by in category: space

This discovery really drives home the point of just how little we know about the universe. We wouldn’t expect a planet this heavy around such a low-mass star to exist.

Unlocking The Mystery Of 137: Why This Number Is So Important

Posted by in category: physics

A s the mathematician De La Soul famously stated, three is the magic number. But if physicist Richard Feynman is to be believed, that figure is off by a factor of about 400. For Feynman, you see, the “magic number” is around 1/137 – specifically, it’s 1/137.03599913.

Physicists know it as α, or the fine structure constant. “It has been a mystery ever since it was discovered,” Feynman wrote in his 1985 book QED: The Strange Theory of Light and Matter. “All good theoretical physicists put this number up on their wall and worry about it.”

Eyeball Planets May Actually Exist, And They’re as Creepy as They Sound

Posted by in category: space

You’ve heard of hot Jupiters. You’ve heard of mini-Neptunes. You’ve heard of super-Earths. But have you heard of Eyeball Planets? Yep — planetary scientists think there might be a type of exoplanet out there that looks disturbingly like a giant eyeball. Just sitting there. Staring.

But it’s actually not as weird as it sounds — the appearance of these bodies has to do with tidal locking.

Tidal locking is when an orbiting body rotates at the same rate that it orbits. That means it always has one side facing the body it is orbiting, and the other side always facing away. The Moon, for instance, is tidally locked to Earth, that’s why we never see its far side from here.

New ‘Mind-Reading’ AI Translates Thoughts Directly From Brainwaves — Without Implants

Posted by in category: robotics/AI

A world-first, non-invasive AI system can turn silent thoughts into text while only requiring users to wear a snug-fitting cap.

The Australian researchers who developed the technology, called DeWave, tested the process using data from more than two dozen subjects.
