Chinese scientists have recently achieved significant advancements in the domain of polarization photodetectors (pol-PDs) by creating an integrated on-chip polarization photodetector. The research group drew inspiration from the remarkable ability of desert ants to see polarization. This unique vision enables desert ants to navigate back to their nests through desolate terrains without relying on visual markers, as their compound eyes can detect polarized sunlight. The researchers aimed to replicate this ability using their polarization photodetector.

Study uncovered earliest evidence transport technology used by ancient settlers
Researchers from Bournemouth University discovered early evidence of transport technology used by settlers in the USA over 20,000 years ago at White Sands National Park, New Mexico. They found drag marks from makeshift vehicles called “travois,” made from wooden poles, alongside ancient human footprints. The tracks included single lines, likely from dragging two poles joined at one end, and parallel lines, from poles crossed in the middle.
The quantum processor that redefines computing speed
Researchers from the University of Science and Technology of China (USTC) have created a superconducting quantum computing prototype called Zuchongzhi-3. This prototype operates with 105 qubits and 182 couplers, making it 1015 times faster than the fastest supercomputer and one million times faster than Google's latest results. This breakthrough marks a significant advancement in quantum computing performance.
MIT Researchers develop improved validation method for more accurate spatial predictions
Researchers at MIT have tackled a perplexing issue in spatial prediction validation, which is critical for fields like weather forecasting and environmental health. Traditional validation methods often fail because they don’t account for the unique characteristics of spatial data, leading to inaccurate forecasts. The research will be presented at the International Artificial Intelligence and Statistics Conference.
Breakthrough algorithm lets you do speech recognition offline
Researchers at the University of Copenhagen have developed a new algorithm that eliminates the need for an internet connection to use speech recognition. This algorithm is proficient at decoding speech without requiring substantial memory allocation. It forgets what it doesn't need in real-time by employing a clever strategy.
