If you've taken a photo in low light you've probably encountered the grainy effect that can dilute the finished product. A new AI tool could prove an incredibly easy way to remove grainy from photos, with the ability to automatically produce a clean image after analyzing only the corrupted version.

Medical X-ray scans have long been stuck in the black-and-white era. Now Mars Bioimaging has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.

Researchers at Dartmouth College have developed a handheld "wand" optical tracking system which it says makes back surgery faster, safer and cheaper. Described as "a Google Maps for the body," the system provides real-time 3-dimensional tracking to help guide the surgeon as they operate.

Regular ultrasound probes have flat bases, which means they only work best when scanning objects that have similarly-flat surfaces. So, what happens if you want to inspect something that's curved or otherwise "irregular" in shape? Well, that's where a new ultrasound patch comes in.

Cloudina was a tiny sea creature that existed about 545 million years ago, and many scientists believe that it played a major role in building the first reefs. Princeton geoscientists Adam Maloof and Akshay Mehra, however, think otherwise – and they do so because of a unique rock-grinding machine.

Researchers at MIT have developed an imaging technique that will help study exactly how electrical signals propagate through the brain, in an advance that could help us better understand Alzheimer's, epilepsy, and other brain disorders, as well as how thoughts and feelings are formed.

Imagine if doctors could see through a patient's skin, and their perspective of the underlying bones and organs changed accordingly as the person moved around. Well, that's what scientists at the University of Alberta have developed – kind of.

Eye exams may be getting quicker and easier, plus ophthalmologists may be able to save money on equipment, thanks to a new instrument developed by scientists in Poland and Spain. Unlike existing eye-examining technology, it allows the entire eye (from front to back) to be imaged via a single lens.

Hyperspectral cameras allow us to see what's invisible to the human eye, and even determine what things are made of. Unfortunately, the devices have tended to be big and cumbersome, limiting them to use in labs. Now, however, there's a portable model on the market.

A team from Rutgers University has devised a ground-breaking new method for detecting tiny cancerous tumors. Using light-emitting nanoparticles the technique can accurately identify and track early-stage tumors months before they grow large enough to be detectable by conventional imaging methods.
