Fact check: Japanese researchers successfully removed the extra chromosome linked to Down syndrome in laboratory cells.

Verdict: mostly true — Trust Score 72/100

This post is confirmed by 4 sources including reports from the BBC, Popular Mechanics, and Nature. While the core scientific events described are authentic 2025-2026 breakthroughs, the post uses AI-generated imagery and contains a geographical error regarding the 3D-printed cornea, which was an Israeli achievement rather than a French one.

Claims analyzed (7)

  1. verified: Japanese researchers successfully removed the extra chromosome linked to Down syndrome in laboratory cells.
    Researchers at Mie University and Fujita Health University published a study in PNAS Nexus (2025) demonstrating the use of CRISPR-Cas9 to remove the extra chromosome 21 in trisomy 21 cell lines.
  2. mostly true: Eye drops that will correct vision without the need for glasses will be available for sale by the end of 2026.
    Several eye drops for presbyopia (age-related near vision loss), such as Vizz (aceclidine) and Vuity (pilocarpine), have been FDA-approved or are entering the market in 2025-2026. However, they only treat near-vision blurriness, not myopia or hyperopia.
  3. verified: South Korea has tested separate walking lanes for fast and slow pedestrians to reduce congestion.
    Reports from May 30, 2026, confirm that South Korea introduced separate pedestrian lanes in major cities to manage traffic flow and reduce stress for commuters.
  4. mostly true: France unveiled an artificial heart that can beat forever without the need for a donor.
    The French company Carmat developed the Aeson Total Artificial Heart, which is a long-term alternative to transplants. While revolutionary, 'forever' is a sensationalist exaggeration for a mechanical device.
  5. verified: Japan achieved a record internet speed of 1.02 petabits per second in laboratory testing.
    Japan's National Institute of Information and Communications Technology (NICT) set a world record of 1.02 Pbps using a 19-core optical fiber over 1,800 km.
  6. mostly true: The world’s first 3D-printed cornea helped restore vision in patients.
    The world's first 3D-printed biological cornea transplant was successfully performed in October 2025 at the Rambam Eye Institute in Israel, developed by Precise Bio. The post's visual flag incorrectly attributes this to France.
  7. mostly true: Brazilian researchers reported promising results from an experimental treatment that helped paraplegic patients regain movement.
    Researchers at UFRJ, led by Tatiana Sampaio, are testing 'polylaminin' for spinal cord regeneration. While some patients have shown movement recovery in pilot studies, the treatment is still in experimental clinical trials.
