A common truism among statisticians is that “the data don’t lie.” However, recent findings by Italian researchers may make those who study data think twice before making such assumptions.

Giuseppe Giannaccare, an eye surgeon at the University of Cagliari in Italy, reports that ChatGPT has conjured reams of persuasive phony data to support one surgical eye procedure over another.

“GPT-4 created a fake dataset of hundreds of patients in a matter of minutes,” Giannaccare said. “This was a surprising—yet frightening—experience.”

There have been countless stories of ChatGPT’s great achievements and potential since the model was unveiled to the world a year ago...

Optical scientists have found a new way to significantly increase the power of fibre lasers while maintaining their beam quality, making them a future key defence technology against low-cost drones and for use in other applications such as remote sensing.

Researchers from the University of South Australia (UniSA), the University of Adelaide (UoA) and Yale University have demonstrated the potential use of multimode optical fibre to scale up power in fibre lasers by three-to-nine times but without deteriorating the beam quality so that it can focus on distant targets.

The breakthrough is published in Nature Communications.

Co-first author Dr Linh Nguyen, a researcher at UniSA’s Future Industries Institute, says the new approach will allow the industry to continue squeezing out ...

University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands.

Professor Robert Prance and Professor Daniel Roggen, of the University of Sussex, have developed the use of electric waves, rather than electromagnetic waves, for a low-power way to transmit data at close range, while maintaining the high throughput needed for multimedia applications.

Transistors are crucial electronic components that regulate, amplify and control the flow of current inside most existing devices. In recent years, electronics engineers have been trying to identify materials and design strategies that could help to further improve the performance of transistors, while also reducing their size.

Two-dimensional (2D) transition metal dichalcogenides have some advantageous properties that could help to enhance the capabilities of transistors. While past studies have demonstrated the potential of these materials in individual transistors, their use for developing entire integrated circuits (ICs) that operate at high frequencies has proved challenging.
