The technology to decode our thoughts is drawing ever closer. Neuroscientists at the University of Texas have, for the first time, decoded data from non-invasive brain scans and used them to reconstruct language and meaning from stories that people hear, see, or even imagine. In a new study published in Nature Neuroscience, Alexander Huth and ...
To build a machine, one must know what its parts are and how they fit together. To understand the machine, one needs to know what each part does and how it contributes to its function. In other words, one should be able to explain the “mechanics” of how it works. According to a philosophical approach ...
Recent public interest in tools like ChatGPT, and its latest iteration GPT-4, has raised an old question in the artificial intelligence community: Is artificial general intelligence (in this case, AI that performs at a human level) achievable? An online preprint this week has added to the hype, suggesting the latest advanced large language model, GPT-4, ...
Are we alone in the universe? An answer to that age-old question has seemed tantalizingly within reach since the discovery of ice-encrusted moons in our solar system with potentially habitable subsurface oceans. But looking for evidence of life in a frigid sea hundreds of millions of miles away in deep space poses tremendous challenges. The science ...
On-chip laser frequency combs — lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb — are a promising technology for a range of applications including environmental monitoring, optical computing, astronomy, and metrology. However, these are still limited by one serious problem — they are not always efficient. ...
Researchers have developed a lensless camera that uses a thin microlens array and new image processing algorithms to capture 3D information about objects in a scene with a single exposure. The lensless camera could be useful for a variety of applications such as industrial part inspection, gesture recognition, and collecting data for 3D display systems. ...
Researchers have discovered a new effect in two-dimensional conductive systems that promises improved performance of terahertz technology in the form of terahertz detectors. A team of scientists at the Cavendish Laboratory together with colleagues at the Universities of Augsburg (Germany) and Lancaster has found a new physical effect when two-dimensional electron systems are exposed to ...
Having trouble hearing? Just turn up your shirt. That’s the idea behind a new “acoustic fabric” developed by engineers at MIT and collaborators at Rhode Island School of Design. The team has designed a fabric that works like a microphone, converting sound first into mechanical vibrations, and then into electrical signals, similar to how our ...
Researchers have developed a new method to display highly realistic holographic images using ‘holobricks’ that can be stacked together to generate large-scale holograms. The researchers, from the University of Cambridge and Disney Research, developed a ‘holobrick’ proof-of-concept that can tile holograms together to form a large seamless 3D image. 3D displays using ‘holobricks’ This is ...
Researchers have developed a new method that can automatically produce clear images so you can see through murky water. The new technology could be useful for searching for drowning victims, documenting submerged archaeological artifacts, and monitoring underwater farms. Being able to clearly see through murky water is extremely challenging because the water and the particles ...
