Harry Potter cloak in three dimension
MUMBAI: Thanks to a group of German scientists who created a three-dimensional “invisibility cloak” that can hide objects by bending light waves, the magical cloak that featured in the Harry Potter series has become closer to reality.
The scientists are from Karlsruhe Institute of Technology in Germany and Imperial College London.
“It‘s kind of like hiding a small object underneath a carpet — except this time the carpet also disappears,” a spokesman of the group said.
“We put an object under a microscopic structure, a little like a reflective carpet,” said Nicholas Stenger, one of the researchers who worked on the project adding, “when we looked at it through a lens and did spectroscopy no matter what angle we looked at the object from, we saw nothing. The bump became invisible,” added Stenger.
The “cloak” hid an object from detection using light of wavelengths close to those that are visible to humans.
Now, the boffins are working to recreate the disappearing bump but on a larger scale.

Utopai Studios unveils 4K three-minute video generation for PAI platform
New Story Agent and editing tools aim to streamline AI-led filmmaking workflows
MUMBAI: Utopai Studios has announced a major upgrade to its PAI storytelling AI platform, introducing what it claims is an industry-first capability to generate three-minute videos in 4K resolution, alongside enhancements to its Story Agent feature.
The update, rolling out from April 15, expands the platform’s capabilities across the filmmaking process, from early concept development to post-production. The company said the new features are designed to help filmmakers maintain continuity across characters, scenes and visual styles, a key challenge in AI-driven storytelling.
At the heart of the release is a next-generation model that enables more structured narrative development, allowing creators to move more seamlessly from idea to execution. With tools such as multi-shot sequencing and multi-turn editing, the platform aims to give both studios and independent creators greater control over complex storytelling workflows.
Commenting on the launch, Utopai Studios co-founder and CTO Jie Yang said, “The next phase of AI in media will not be defined by isolated tools, but by systems that can carry story, continuity and collaboration across the full creative process.” He added that the update is a step towards enabling more practical, end-to-end narrative development at a professional level.
Echoing this, Utopai Studios co-founder and chief scientific officer Zijian He said, “Generative video is opening the door to a new production model, where creative ambition is less constrained by traditional cost and complexity.” He noted that the platform combines multimodal models with iterative editing to give creators more speed, control and consistency.
The company said PAI is already being used in professional film and television productions, particularly in Hollywood, for tasks such as pre-visualisation, scene design and post-production refinements. The latest update adds features including improved voice options, character consistency, unlimited editing and more flexible asset management.
Utopai also emphasised that its models are not trained on copyrighted material, positioning the platform as a cleaner alternative for creators and rights holders navigating the evolving AI landscape.
As AI continues to reshape content creation, Utopai’s latest push signals a shift from standalone tools to integrated systems, aiming to make high-quality filmmaking faster, more flexible and increasingly accessible.
