Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Researchers develop a laser that produces the strongest ultra-short laser pulses to date
The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry often also require very short and strong pulses of la.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
Powerful and compact optical frequency combs provide unique opportunities
Remember those big, clunky machines needed for super precise light measurements? Those days are fading thanks to tiny devices called microcombs. These chips can do the same job, but on a much smaller scale, opening doors for new applications......»»
How did the building blocks of life arrive on Earth? Zinc fingerprints in meteorites offer clues
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may not have been enough of these compounds on Earth f.....»»
