The Grand Staircase inside Hogwarts Castle is magically whimsical, unpredictably opening up new routes while simultaneously closing others. How could this possibly be analogous to a quantum computer architecture?

🔬 EPFL researchers have collaborated with those at the Chinese Academy of Sciences on a #microscopy method that makes it possible to observe suspended cells in a more natural environment.
The scientists used two optical methods -- optical sectioning and #opticaltweezers -- to image and manipulate suspended cells in 3D. Until now, this was only possible by fixing cells to a substrate with an artificial medium.

We experimentally demonstrate stable trapping and controlled manipulation of silica microspheres in a structured optical beam consisting of a dark focus surrounded by light in all directions - the so-called Dark Focus Tweezer. Results from power spectrum and potential analysis demonstrate the non-harmonicity of the trapping potential landspace, which is reconstructed from experimental data in agreement to Lorentz-Mie numerical simulations. Applications of the dark tweezer in levitated optomechanics and biophysics are discussed.
Hello everybody - here’s my #introduction.
I was a #research #scientist for many years working on #cryobiology, artificial #liver systems, #lasers, #microscopy, and #OpticalTweezers.
I now work as a #grant #funding research development manager. I spend my days reading grant applications and working with hundreds of fantastic #academics in the beautiful town of #StAndrews #Scotland.
I am interested in #sustainability and how we can make the world a better place.

We can test the quality and freshness of fruits and vegetables with our fingers, and even industrial robots have been performing successfully at tactile applications for years. But how is it possible to grab and rotate objects with the width of a human hair? Prof. Dr. Alexander Rohrbach from the University of Freiburg's Department of Microsystems Engineering and his team have now published a study on this question in the journal Nature Communications. Their work demonstrates how several optical tweezers made of highly focused laser light will one day be able to grab cell clusters in a controlled manner and rotate them in any desired direction. This will allow tiny objects like miniature tumors to be studied more specifically under the microscope.
