(PDF) Photosynthesis in human beings as a natural food through the blue light

The article explains how photosynthesis occurs in humans. It is disclosed that hemoglobin as a photosynthetic pigment is responsible for this process, its structure is identical to chlorophyll in plants, the only thing that changes is the central metallic ring, which in plants is magnesium that gives it its green color. and in humans it is the iron that gives it its red color.

Nova explosion of nearby star will soon light up Earth’s skies

The vast expanse of the night sky, a canvas dotted with countless stars, is about to unveil a rare and spectacular phenomenon. Brace yourself for a stellar light show as T Coronae Borealis, a seemingly unremarkable star nestled within the constellation Corona Borealis, is on the brink of a dramatic nova explosion.

T Coronae Borealis, affectionately known as T CrB, is no ordinary star. It’s a binary system, a celestial pattern of two stars locked in a gravitational embrace.

At the heart of this cosmic process lies a white dwarf, the incredibly dense remnant of a once-mighty star. Its partner, a bloated red giant, is in the twilight years of its existence, slowly shedding its outer layers under the relentless pull of the white dwarf’s gravity.

AI RoboCasa simulation developed to train robots for household chores

From mundane chores to complex interactions, RoboCasa trains robots to navigate the real world:


Researchers have developed a large-scale simulation framework for training general-purpose robots in diverse, everyday settings.

The framework, called RoboCasa, provides access to thousands of 3D assets over more than 150 object categories, as well as dozens of furniture and appliances that may be interacted with.

A range of generative AI tools are used to increase realism and diversity, including text-to-3D models for object assets and text-to-image models for environmental textures.

US hits 180 GW of solar power. Here’s how we get to 1,000 by 2035

Collectively, the US’s 5 million solar installations can generate more than 179 gigawatts (GW) of electricity. Based on current trends, the SEIA claims that the US’s total solar capacity will soar to 673 GW by 2034, providing enough electricity to power 100 million homes.

The US will likely need to do better than that to meet the Biden Administration’s goal of 100% clean electricity by 2035, though. To decarbonize the grid by then, the Department of Energy (DoE) expects we’ll need as much as 1 terawatt (1,000 GWs) of solar capacity, enough for solar to meet 30–50% of the US’s electricity demand by itself.

New 3D printing technique integrates electronics into microchannels to create flexible, stretchable microfluidic devices

The transition from traditional 2D to 3D microfluidic structures is a significant advancement in microfluidics, offering benefits in scientific and industrial applications. These 3D systems improve throughput through parallel operation, and soft elastomeric networks, when filled with conductive materials like liquid metal, allowing for the integration of microfluidics and electronics.

New quantum random number generator achieves 2 Gbit/s speed

The reliable generation of random numbers has become a central component of information and communications technology. In fact, random number generators, algorithms or devices that can produce random sequences of numbers, are now helping to secure communications between different devices, produce statistical samples, and for various other applications.
