New Nanotechnology Allows for Touchless Optical Finger Motion Tracking

Scientists from the Max Planck Institute have developed nanostructures that change their electrical and even their optical properties as soon as a finger comes anywhere near them, making touchless optical finger tracking possible. While touchscreens are practical, touchless displays would be even more so. That’s because, despite touchscreens having enabled the smartphone’s advance into our […]

NASA Engineers Successfully Test Heat Shield for Future Mars Exploration Vehicles

NASA engineers have successfully completed heat shield testing of an Adaptive Deployable Entry and Placement Technology (ADEPT) model under conditions akin to entering the Martian atmosphere. As NASA missions to Mars progress with science and complex human exploration missions, spacecraft will require larger heat shields to protect against the extreme heat of entering a planet’s atmosphere and […]

A Light-Reflecting Balloon Catheter Repairs the Heart without Surgery

Using a catheter aided by UV light, researchers have developed a new technique to repair holes in the heart without surgery. Harvard-affiliated researchers have designed a specialized catheter for fixing holes in the heart by using a biodegradable adhesive and patch. The team reported in the journal Science Translational Medicine that the catheter has been used successfully […]
