A groundbreaking study from the University of Toronto has demonstrated the existence of ‘negative time’ through advanced quantum experiments. While once dismissed as an illusion caused by light waves interacting with matter, researchers now argue it is a real and measurable phenomenon. The findings, though not yet peer-reviewed, have sparked global interest and scepticism.
Led by Daniela Angulo, the research focused on how photons interact with atoms, showing that the duration atoms remain in an excited state can be less than zero. Visualised as cars exiting a tunnel before they seemingly enter, the experiments suggest a counterintuitive quirk of quantum mechanics, challenging conventional perceptions of time but adhering to Einstein’s theories of relativity.
The study required over two years of meticulous work to fine-tune experimental conditions. Aephraim Steinberg, a quantum physics professor, emphasised that the results do not imply time travel or backward motion of particles but rather an intriguing aspect of how quantum particles behave.
Critics, including German physicist Sabine Hossenfelder, argue the concept is a descriptive tool rather than a revelation about time itself. Despite the controversy, the team stands by their findings, believing it provides a fresh lens to study quantum phenomena, even if practical applications remain distant.

Researchers have achieved a milestone in AI, teaching it to predict the complex aromas of whiskies and even identify their origins. The study, conducted in Germany, utilised AI to analyse the molecular makeup of 16 American and Scottish whiskies. It then predicted the five strongest aroma notes and distinguished between the two countries of origin with remarkable accuracy.
The AI surpassed human experts in consistency and precision, identifying aromas like menthol and citronellol for US whiskies and smoky, medicinal notes for Scotch. This innovation could ensure flavour consistency in whisky production, detect counterfeit goods, and even find applications in blending recycled materials to reduce odours.
While promising, the study was limited to a small selection of whiskies, raising questions about its performance on broader varieties or aged batches. Experts also noted that flavour perception depends on external factors, highlighting room for further exploration in this emotive domain. Nonetheless, this blend of technology and tradition signals a new step for the whisky industry.

Quantization, a technique widely used to improve AI efficiency, may have reached its limits, according to recent research. This method reduces the precision of data in AI models, making them faster and cheaper to operate. However, studies suggest that as models grow larger and are trained on vast datasets, quantization can degrade their performance.
Researchers from leading institutions found that highly trained models suffer more when quantised. For AI companies relying on massive models to enhance quality, this finding raises concerns about the long-term viability of cost-saving approaches. Quantization already impacts models like Meta’s Llama 3, which reportedly shows reduced performance compared to other AI systems.
Efforts to lower AI model costs continue as inference—using models to generate responses—remains the most significant expense for AI labs. Techniques like training in low precision and hardware supporting ultra-low bit precision are being explored. Yet, such strategies face diminishing returns and risks of quality loss if precision drops too far.
Experts believe a shift towards better data curation and filtering, alongside new architectures optimised for low-precision training, may offer solutions. These advancements could help balance efficiency and performance as AI evolves beyond traditional scaling methods.
