New laser power converters can transmit power to further, remote destinations

From smart grids to the internet of things, the modern world is increasingly reliant on connectivity between electronic devices. Thanks to University of Ottawa researchers, these devices can now be simultaneously connected and powered with a simple optical fiber over long distances, even in the harshest environments.

This significant step forward in the development of photonic power converters—devices that turn into —could integrate laser-driven, remote power solutions into existing fiber optic infrastructure. This, in turn, could pave the way for improved connectivity and more reliable communication in remote locations and extreme situations.

“In traditional power over fiber systems, most of the laser light is lost,” explains Professor Karin Hinzer of the University of Ottawa’s SUNLAB, which collaborated with Germany’s Fraunhofer Institute for Solar Energy Systems on the study. “With these new devices, the fiber can be much longer.”

Tesla Responds w/ Huge Hardware Change to Improve Autonomy

Questions to inspire discussion.

🚕 Q: How reliable is Tesla’s robotaxi service based on recent experiences? A: Tesla’s robotaxi service has perfect rides in 9 out of 10 experiences, with one incident of phantom braking due to sun glare.

📱 Q: How do users access and pay for Tesla’s robotaxi service? A: Users access the service through a separate app from the Tesla app, requiring Tesla sign-in and linked credit card information for payment.

Tesla Model Updates and Pricing.

🔋 Q: What changes were made to the refreshed Model S and X? A: The refresh includes new hardware for improved autonomy, new color options, wheel design, and ambient lighting, with a $5,000 price increase and 5–7% range increase.

🛡️ Q: What does Tesla’s new extended warranty plan offer? A: Tesla’s plan extends coverage for 4 years or 100,000 miles at $50–150 per month depending on the model, covering most manufactured parts except the high-voltage battery, tires, and glass.

Affordable laser could be mass-produced for use in self-driving cars and fiber optics

Laser technology is used in many areas, where precise measurements are required and in communication. This means that they are important for everything from self-driving cars to the fiber optic internet and for detecting gases in the air.

Now, a research group has come up with a new type of laser that solves several problems associated with current-day lasers. The group is led by Associate Professor Johann Riemensberger at NTNU’s Department of Electronic Systems.

“Our results can give us a new type of laser that is both fast, relatively cheap, powerful and easy to use,” says Riemensberger.

Google rolls out new Gemini model that can run on robots locally

Google DeepMind on Tuesday released a new language model called Gemini Robotics On-Device that can run tasks locally on robots without requiring an internet connection.

Building on the company’s previous Gemini Robotics model that was released in March, Gemini Robotics On-Device can control a robot’s movements. Developers can control and fine-tune the model to suit various needs using natural language prompts.

In benchmarks, Google claims the model performs at a level close to the cloud-based Gemini Robotics model. The company says it outperforms other on-device models in general benchmarks, though it didn’t name those models.

Scientists create ‘universal translator’ for quantum tech

Scientists at UBC have devised a chip-based device that acts as a “universal translator” for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and noise. This innovation preserves crucial quantum entanglement and works both ways, making it a potential backbone for a future quantum internet. By exploiting engineered flaws in silicon and using superconducting components, the device achieves near-perfect signal translation with extremely low power use and it all fits on a chip. If realized, this could transform secure communication, navigation, and even drug discovery.

Teleportation Becomes a Scientific Reality

When we think about the future of our communications, we rarely imagine that it could be hidden in the intricacies of the infinitely small. Yet, it is there, among frisky photons, that the next digital revolution could take shape. A simple photon, teleported from one point to another across the globe via the Internet, opens up dizzying horizons. Who would have thought that the key to our future exchanges would lie in an elementary particle, capable of challenging everything we thought we knew about information transmission?

Researchers at Northwestern University have recently achieved a major milestone in the field of quantum physics. They have succeeded in teleporting a photon over a distance of 30.2 km through an Internet network. This feat, once confined to the realm of science fiction novels, represents a significant advance in exploring the possibilities offered by quantum entanglement. With this accomplishment, the foundations of a future global quantum network seem to be rapidly approaching.

Iran’s State TV Hijacked Mid-Broadcast Amid Geopolitical Tensions; $90M Stolen in Crypto Heist

Cybersecurity firm Radware said nearly 40% of all hacktivist DDoS activity has been directed against Israel since the onset of the latest flare-up. On June 17, the hacktivist group DieNet warned it would launch cyber-attacks at the United States should it join the conflict against Iran.

The message has since been amplified by other groups like Arabian Ghosts, Sylhet Gang, and Team Fearless, suggesting that these entities are forming a potential collaboration in cyberspace as battle rages on the ground.

“Companies are urged to take maximum vigilance. The warning signs are clear. Critical infrastructure, supply chains, and even global businesses could become collateral targets if the cyber crossfire intensifies,” said Pascal Geenens, director of threat intelligence at Radware.

Massive 7.3 Tbps DDoS Attack Delivers 37.4 TB in 45 Seconds, Targeting Hosting Provider

“Hosting providers and critical Internet infrastructure have increasingly become targets of DDoS attacks,” Cloudflare’s Omer Yoachimik said. “The 7.3 Tbps attack delivered 37.4 terabytes in 45 seconds.”

Earlier this January, the web infrastructure and security company said it had mitigated a 5.6 Tbps DDoS attack aimed at an unnamed internet service provider (ISP) from Eastern Asia. The attack originated from a Mirai-variant botnet in October 2024.

Then in April 2025, Cloudflare revealed it defended against a massive 6.5 Tbps flood that likely emanated from Eleven11bot, a botnet comprising roughly 30,000 webcams and video recorders. The hyper-volumetric attack lasted about 49 seconds.
