- Researchers in Japan have shattered the internet speed record achieving a jaw-dropping data transmission rate of 125,000 gigabytes per second — roughly 4 million times faster than the average U.S. broadband speed.
- The record-breaking internet speed was achieved by researchers at Japan’s National Institute of Information and Communications Technology (NICT). They collaborated with Sumitomo Electric Industries to develop the 19-core optical fiber that made the breakthrough possible.
- Here’s what made this feat possible:
- Researchers developed a new fiber containing 19 cores packed into a cable just 0.127 mm wide, the same size as standard cables. This design minimizes light fluctuation and data loss.
- Side Note – A cable with a conductor size of 0.127 mm (which corresponds to 26 AWG) is typically used in low-voltage, high-speed data transmission applications. Here are a few examples of where this size shows up:
- Common Cable Types with 0.127 mm Conductors
-
Ribbon Cables
- Often used for internal connections in computers and electronics (e.g., between a motherboard and a drive).
- Example: TRU COMPONENTS TC-7638628 — a 64-pin ribbon cable with 7 conductors, each 0.127 mm wide.
-
Multicore Shielded Cables
- Used in signal, voice, and data transmission for industrial and medical equipment.
- These often feature multiple strands of 0.127 mm conductors bundled together for flexibility and shielding.
-
Single-Core UL-Style Wires
- Found in electronics and prototyping, especially UL-Style 1061 or 10002.
- These wires use 7 strands of 0.127 mm diameter copper to form a flexible conductor.
-
Why Use 0.127 mm Conductors?
- Flexibility: Thin strands allow for tight bends and compact routing.
- Signal Integrity: Ideal for short-distance, high-frequency signals.
- Space Efficiency: Perfect for densely packed electronics.
- Long-Distance Transmission: The data traveled 1,120 miles — about the distance from New York to Florida — by looping through the system 21 times, showcasing the fiber’s strength over vast distances.
- This speed is more than double the previous record of 50,250 Gbps set in 2024.
- Because the cable matches existing dimensions, it could be deployed without overhauling current systems.
- Global Impact: With data traffic expected to surge, this innovation could revolutionize long-haul, high-capacity internet infrastructure.
- At this speed, you could download the entire Internet Archive in under four minutes.
- Side note: The “Internet Archive” refers to a massive digital library hosted at archive.org. It’s a nonprofit project founded in 1996 with the mission of providing universal access to all knowledge. Here’s what it includes:
-
Types of Content
- Over 562 billion web pages via the Wayback Machine
- Millions of books, including rare and out-of-print titles
- Extensive collections of audio recordings, including live concerts and radio shows
- Thousands of videos, from documentaries to vintage TV broadcasts
- A vast archive of software, including playable retro games and emulators
- Historical images, maps, and artwork
- The total size of the Internet Archive exceeds 70 petabytes of data.
- It’s one of the largest digital repositories in the world.
Story 2: Breakthrough US thermal coating cools buildings by 36°F, slashes AC bills, power use
Source: TimesofInnovation.com Story by Kir Birkin
- A new AI-enhanced thermal coating can cool buildings up to 36°F [approximately 2.2° Celsius], significantly reducing reliance on air conditioning.
- The technology was developed by an international team of researchers from:
- University of Texas at Austin
- Shanghai Jiao Tong University
- National University of Singapore
- Umeå University in Sweden
- The [building] coating reflects a large portion of solar heat and adapts in real time to environmental conditions.
- One of the most remarkable aspects of this breakthrough thermal coating is its integration of artificial intelligence (AI) technology in its development.
- Through the use of AI algorithms [in the development phase], the coating is able to adapt to changing environmental conditions in real-time, optimizing its performance based on factors such as outdoor temperature, sunlight intensity, and building occupancy.
- The AI in the University of Texas at Austin’s thermal coating project isn’t controlling the material in real time—it was used in the design phase [of the thermal coating] to engineer the coating’s properties before application.
- Here’s how AI played a role in the creation of the material:
- Researchers developed a machine learning framework to create thermal meta-emitters — materials that can selectively emit heat at specific wavelengths.
- The AI explored over 1,500 material combinations, optimizing for cooling performance and energy efficiency.
- Instead of manually testing materials, the AI used inverse design: it started with desired thermal properties and worked backward to find the best structure and composition.
- This approach dramatically expands the design space, allowing for complex 3D geometries that outperform traditional thin-film coatings for buildings.
- The key to the effectiveness of this thermal coating lies in its advanced composition, which is designed to reflect a significant portion of the sun’s heat away from the building.
- By leveraging the principles of heat reflection and dissipation, this technology ensures that the interior spaces remain cool even in the hottest weather conditions.
- As a result, occupants can enjoy a comfortable indoor environment without the need for excessive air conditioning, leading to lower electricity bills and reduced carbon emissions.
-
Applications:
- Residential and commercial buildings.
- Potential use in textiles, vehicles, and even spacecraft for thermal regulation.
- Performance Recap: In tests, buildings coated with this material stayed up to 36°F cooler than those with standard white or gray paints.

- Researchers at KAIST (Korea Advanced Institute of Science and Technology) have developed a groundbreaking drug that restores vision by regenerating retinal nerves — marking the first long-term neural regeneration in mammalian retinas.
- How It Works
- The drug targets PROX1, a protein that blocks retinal regeneration.
- Side note – PROX1 (Prospero Homeobox 1) is a homeobox transcription factor—a type of protein that binds DNA and regulates gene expression, especially during development.
- In mammals, PROX1 accumulates in Müller glia cells after retinal damage, preventing them from becoming regenerative stem cells.
- Side note – Müller glia cells are the principal support cells of the retina—think of them as the retina’s built-in maintenance crew and emergency responders.
- Key Characteristics
- Location: Found throughout the vertebrate retina, spanning its entire thickness from the inner to outer limiting membranes.
- Structure: Radially oriented, making contact with nearly every retinal cell type—photoreceptors, bipolar cells, ganglion cells, and blood vessels.
- Origin: Derived from neuroepithelial progenitors during retinal development.
- By using an antibody to neutralize PROX1, researchers enabled these cells to regenerate retinal neurons.
- Results in Mice
- In mouse models of retinitis pigmentosa, the treatment restored the photoreceptor layer and significantly improved vision.
- The effects lasted over six months, a major milestone in retinal therapy.
- What’s Next
- The therapy is being developed by Celliaz Inc., a biotech startup from the KAIST lab.
- Clinical trials are expected to begin by 2028.
- This could be a game-changer for millions affected by degenerative retinal diseases like macular degeneration and glaucoma.

Story: Scientists extracted water and oxygen from moon dust using sunlight. Could it work on the lunar surface?
Source: Space.com Story by Keith Cooper
- Chinese scientists have developed a one-step method to extract water and oxygen from lunar soil using **sunlight**, potentially revolutionizing how future moon missions sustain life.
- The process uses photothermal catalysis, where sunlight heats lunar regolith (soil) to release water vapor.
- That vapor is then combined with **carbon dioxide** (like what astronauts exhale), and catalyzed by **ilmenite**, a mineral in moon dust, to produce oxygen and methane —the latter being a stable rocket fuel.
- Transporting water from Earth to the Moon costs about $83,000 per gallon, and astronauts need ~4 gallons daily.
- This method could drastically reduce costs and infrastructure complexity for lunar bases.
- Tests used simulants based on samples from China’s **Chang’e 5 mission**.
- Experts caution that lunar regolith is a strong thermal insulator, making uniform heating difficult.
- The Moon’s extreme temperature swings and dust could complicate machinery reliability.
- Astronauts may not produce enough CO₂ to sustain the reaction, possibly requiring supplemental sources.
- Researchers aim to scale the technology and test its viability under actual lunar conditions.
- If successful, it could support in-situ resource utilization (ISRU)—using local materials to sustain human life and exploration.
