Imaging

Terahertz radiation is extremely useful but, traditionally, tricky and expensive to generate. Scientists at TU Wien have come up with a new source of terahertz radiation that they claim breaks records for efficiency and the breadth of its spectrum.

Utilizing a recently developed brain imaging technique new research suggests measuring accumulated levels of a protein called tau may predict future neurodegeneration associated with Alzheimer’s disease.

A study claims to have identified white matter brain damage in obese teenagers. The research suggests the structural changes correlate with inflammatory markers, and were not seen in non-obese subjects, implying obesity may be the causal factor.

Researchers have developed a flat lens that's one one-thousandth the thickness and one one-hundredth the weight of a conventional model.

​For decades scientists have been exploring the minds of criminals and a new study is taking this research further than anyone has before, suggesting the brains of individuals that have committed murder are notably different from other criminals, both violent and non-violent​.

A completely new category of microscopy has been invented by researchers in the US. Dubbed DNA microscopy, the technique tags RNA molecules with a range of DNA "barcodes" which in turn flag the identity and location of the molecules, even when they're stacked on top of each other.

Google's wizardry with computational imaging is at the heart of what makes its Pixel phones such impressive photography tools despite the fact that they only have single 12.2-megapixel cameras. A new paper reveals some of the magic behind the impressive Night Sight and Super-Res Zoom features.

The pigment melanin is a natural defense against skin cancer – and now it could help fight other cancers too. Researchers at the Technical University of Munich and Helmholtz Zentrum München have found that melanin-loaded nanoparticles can help diagnose tumors and slow their growth.

Scientists and engineers often turn to high-speed cameras to better understand rocket launches, lightning and viper strikes, and now researchers in Switzerland are now proffering such folks a brand new tool they say will work with any kind of camera.

The earlier cancer is detected, the better the odds of treating it, but tumors can be hard to spot until they get to a certain size, at which point it might be too late. Now MIT researchers have developed a new optical imaging system that could be used to spot tiny tumors deep inside the body.

It has been years since Google’s influential Street View left the roads and began to map everything from shopping centers to hiking trails. The device that made this happen was called the Street View Trekker, and Google just revealed an updated model.

A new study suggests an MRI scan can predict whether a person will develop dementia up to three years before any cognitive symptoms are detectable. It's hoped the tool will be able to better identify at-risk patients so preventative measures can be deployed to slow the onset of neurodegeneration.
