It’s easy to forget that most animals don’t see the world the way humans do. In fact, with infrared and ultraviolet sight, many animals experience a world that is completely invisible to us.Now, however, scientists have developed hardware and software that allows you to capture footage as if it was filmed through the eyes of animals such as honeybees and birds.It’s an intriguing, revealing look at nature and animal behavior, and one the researchers from the University of Sussex and the Hanley Color Lab at George Mason…

OpenET uses publicly available data produced by NASA and USGS Landsat and other satellite systems to calculate…

Researchers have developed a deep learning-based AI algorithm that automatically analyzes chest X-rays to rapidly detect COVID-19 infection with more than 98% accuracy, distinguishing between normal X-rays and X-rays from people with pneumonia, which often presents with the same symptoms as COVID.Real-time reverse transcription-polymerase chain reaction (RT-PCR) testing is the most widely used method of diagnosing COVID-19 infection. But there are issues with using real-time PCR testing: it’s costly, results can be slow,…

The findings indicate a moderate correlation between self-reported usage and actual screen time. However, a notable finding is that the longer individuals engage with social media or smartphones, the less accurate their self-reporting of use…

The Internet of Things (IoT) has ushered in a new era of connectivity, allowing a multitude of devices to communicate and share data. However, the vast and diverse nature of IoT data sources poses significant challenges in terms of data accuracy and consistency. Data fusion and management have emerged as critical components in addressing these challenges, ensuring that the information collected from IoT devices is reliable and useful. In this technical article, we delve into key aspects of data fusion and management in…

A team of Danish engineers and AI scientists from the Technical University of Denmark have come up with a new ChatGPT-like AI system that studies the life of a subject, and predicts how an individual's life will turn out, and if they will have an early death, all with great accuracy…

Researchers have taken photographs of children’s retinas and screened them using a deep learning AI algorithm to diagnose autism with 100% accuracy. The findings support using AI as an objective screening tool for early diagnosis, especially when access to a specialist child psychiatrist is limited.At the back of the eye, the retina and the optic nerve connect at the optic disc. An extension of the central nervous system, the structure is a window into the brain and researchers have started capitalizing on their ability…

DOI: 10.1186/s43020-023-00119-0 In a study published on 13 November 2023, in the journal Satellite Navigation, researchers from Chang'an University have developed a novel approach using the Precise Point Positioning (PPP) technique combined with a cumulative sum control chart (CUSUM) method. This method enables the…

The hype around AI continues to spread, and we’re seeing new ways that AI can make our lives easier and even more productive. The latest experiment to see some success shows that AI can recreate clothing just by looking at a single image of the clothing in question. It’s an intriguing experiment, and one that the researchers say has shown a 95.7 percent success rate at recreating the clothing that it was shown. The experiment is a two-stage AI system known as Sewformer. The researchers trained it on 1 million…
