Collaborate Disseminate
Scientists at the University of Nottingham have developed a first-of-its-kind imaging sensor designed to be deployed inside the human body to build 3D maps of cellular structures. The prototype device, which combines lasers and sound waves in an optica… Continue reading World-first imaging probe searches for cancer with lasers and sound
While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to …read more Continue reading Ultrasonic Sonar Detects Hidden Objects
University of Washington researchers studying the potential medical use of smart speakers such as Amazon’s Echo and Google’s Nest have recently released a paper detailing their experiments with non-contact acoustic …read more Continue reading Hey Google, is My Heart Still Beating?
We are big fans of POV displays, particularly ones that move into 3D. To do so, they need to move even faster than their 2D cousins. [danfoisy] built a volumetric …read more Continue reading Surf’s Up, A Styrofoam Ball Rides the Waves to Create a Volumetric Display
There are many schools of thought when it comes to keeping vinyl records clean. It’s a ritual that’s nearly as important as the one that comes after it — queuing up the record and lowering the needle. We’ve seen people …read more
It’s common knowledge that bats navigate and search for their prey using echolocation, but did you know that the ultrasonic chips made by different species of bats are distinct enough that they can be used for identification? [Tegwyn☠Twmffat] did, which is why he came up with this impressive device capable …read more

Radars are simply cool, and their portrayal in movies and TV has a lot to do with that. You get a sweet glowing screen that shows you where the bad guys are, and a visual representation of your missiles on their way to blow them up. Sadly, or perhaps …read more
Bats use echolocation to see objects in front of them. They emit an ultrasonic pulse around 20 kHz (and up to 100 kHz) and then sense the pulses as they reflect off an object and back to the bat. It’s the same type of mechanism used by ultrasonic proximity sensors …read more
It’s often said that necessity breeds creativity, and during a global pandemic such words have proved truer than ever. Realising the common doorbell could be a potential surface transmission point for coronavirus, [CasperHuang] whipped up a quick build.
The build eschews the typical pushbutton we’re all familiar with. Instead, it …read more

Those of you with an eye to classic cinema will remember 1985’s Back To The Future, and particularly its scientist character Dr. Emmett Brown. When the protagonist Marty McFly finds himself in 1955, on his first meeting with they younger Dr. Brown the latter is wearing an experimental helmet …read more
