New models show that the earth is warming faster than first thought

Scientists have made no secret of the extreme challenges posed by climate change, with the Intergovernmental Panel for Climate Change (IPCC) repeatedly stressing the importance of keeping global warming below two degrees. But now it seems the situati...

AI could be the key to catching Type 1 diabetes much earlier

Will AI lead to a quicker diagnosis of diabetes, a condition often called the silent killer? IBM researchers are hoping so. They recently announced an AI-powered screening tool that could potentially identify Type 1 diabetes antibodies in people's bl...

AI can predict heart attacks more accurately than doctors

An estimated 20 million people die each year due to cardiovascular disease. Luckily, a team of researchers from the University of Nottingham in the UK have developed a machine-learning algorithm that can predict your likelihood of having a heart atta...

University of Glasgow makes 3D models with single-pixel sensors, skips the cameras (video)

University of Glasgow creates 3D with singlepixel sensors, skips the cameras video

Most approaches to capturing 3D models of real-world objects involve multiple cameras that are rarely cheap, and are sometimes tricky to calibrate. The University of Glasgow has developed a method that ditches those cameras altogether. Its system has four single-pixel sensors stitching together a 3D image based on the reflected intensity of light patterns cast by a projector. Reducing the pixel count lowers the cost per sensor to just a few dollars, and extends the sensitivity as far as terahertz wavelengths. Real-world products are still a long way off, but the university sees its invention as useful for cancer detection and other noble pursuits. Us? We'd probably just waste it on creating uncanny facsimiles of ourselves.

Qumarion 3D modeling mannequin coming soon for $750, still won’t play with your kid (video)

Image

Trying to get convincing, natural poses out of 3D models can be tricky, so it's a relief that two Japanese universities' joint ventures, the University of Electro-Communications' ViVienne and the University of Tsukuba's SoftEther, are close to wrapping up work on their posable mannequin. Now called Qumarion, the model formerly known as QUMA uses 32 sensors across 16 body joints to translate the humanoid statue's pose to the computer screen simply by bending limbs, much like you would the legion of action figures you had when you were eight. Neither you nor your kids will be using Qumarion to storm Fort Barbie anytime soon, but the 120 frames per second sample rate over USB does mean that poses are mirrored in your modeling tools almost instantly. You also won't have much longer to wait to buy one for your fledgling anime production: the mannequin and custom modeling software from Celsys should be bundled together sometime within the summer for a comparatively frugal $750.

Self-sculpting ‘smart sand’ can assume any shape, create instant prototypes (video)

Image
A new algorithm developed by the Distributed Robotics Laboratory at MIT's Computer Science could lead to an exciting fast prototyping tool, being dubbed "smart sand." Immerse an object in the sand, tiny cubes that send simple proximity messages to each other, which relay through the swarm and determine which blocks are adjacent to the object to be modeled, and those that aren't. Using this data, it's possible to create a map of the subject to be replicated. Initial tests were performed using 2D models, but has also been shown to work reliably with 3D shapes also. While true smart sand would need "grains" much smaller than currently possible, it's said that this isn't an "insurmountable obstacle." The paper will be presented at the IEEE conference in May, or keep going past the break for the explanatory video.
