Microcombs are small photonic devices that could help improve the energy efficiency of the internet, monitor our health, or even discover new Earth-like exoplanets. Swedish researchers have developed a unique, game-changing microcomb that could bring these advanced applications a step closer.
What is a Microcomb?
A frequency comb is a unique laser source where the emission spectrum consists of a series of discrete, equally spaced frequency lines. It works similarly to a ruler made of light; markers set the frequency scale across the electromagnetic spectrum from ultraviolet to the mid-infrared, with each marker s location linked to a known reference.

Allergies, the most common chronic diseases affecting children, are on the rise.
According to the European Academy of Allergy and Clinical Immunology (EAACI), the number of children with allergies has doubled in the last 10 years, and visits to A&E have increased seven-fold.
Food allergies vary across the bloc. In continental Europe, the most common allergies are triggered by fresh fruit and vegetables, whereas in Anglo-Saxon countries, most food allergies relate to hazelnuts, peanuts and walnuts. In Northern Europe, allergy to fish and shellfish are the most common.
