A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...

Making 3D printing truly 3D

Don't be fooled by the name. While 3D printers do print tangible objects (and quite well), how they do the job doesn't actually happen in 3D, but rather in regular old 2D.

Edible, fluorescent silk tags can suss out fake medications

Recent developments such as the explosion of online pharmacies and supply chain issues have made it easier for counterfeiters to profit from fake or adulterated medications. Now, researchers reporting in ACS Central Science ...

Maintaining the structure of gold and silver in alloys

EPFL engineers have developed a low-temperature annealing method that maintains the structure of gold and silver when the two metals are combined in an alloy. Their discovery will prove useful in the manufacture of contact ...

Mapping the movement of white dwarfs of the Milky Way

White dwarfs were once normal stars similar to the sun but then collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. However, a recent study from Lund University ...

Next-generation camera can better locate tumors

A few years ago, Edoardo Charbon, an EPFL professor and head of the Advanced Quantum Architecture Laboratory, unveiled a new, ultra-high-power camera called Swiss SPAD2. His device was the first to be able to capture and ...

Biophotonic probes for bio-detection and imaging

Sensitive detection and imaging in bio-microenvironment is highly desired in biophotonic and biomedical applications. However, conventional photonic materials inevitably show incompatibility and invasiveness to bio-systems. ...
