Visual Scanning of the Chemical Structure of Single Molecules at Angstrom Resolution

Nanocavity plasmonic fields can create Raman images of molecular vibration for a visual system that can map the chemical structure of single-molecule. This visual system has 0.1 nanometer (an angstrom) resolution. They merge the images at several different vibration modes to generate the image with the chemical structure. Arxiv has the full article. Scanning Raman picoscopy (SRP) is the first optical microscopy technique that has the ability to visualize the vibrational modes of a molecule and to directly construct the structure of a molecule in real space. The protocol established in this proof-of-principle demonstration can be generalized to identify other

The Only Version of Return of the King Worth Watching Missing From Max After Streaming Bug

Screenshot: Warner Bros. Bad news for Max subscribers who’ve made re-watching The Lord of the Rings extended editions an annual New Year tradition: the third film in the trilogy, The Return of the King — which just celebrated its 20th anniversary! —is only available to stream in its theatrical version. No ancient evil is to blame, thankfully; it’s an unspecified “tech issue,” according to a Max spokesperson who responded to a comment request from Vulture after the issue was noted by dismayed fans on Reddit .

You Can Visit Freddy Fazbear's Pizza in Hollywood

Image: Universal Pictures Just in time for Halloween and for the release of Blumhouse and Universal Pictures’ Five Nights at Freddy ’s fans can visit a pop-up location of the fictional franchise from the game and film. That’s right, a Freddy Fazbear’s Pizza has mysteriously appeared in Hollywood. Like in the game and upcoming film, it’s a run-down spot that’s been closed down due to some mysterious activity within. Unfortunately, you can’t actually go in unless you’re hired as a security guard (kidding)—it’s just a facade for photo-ops you can visit. Check out the video captured by deadboifilms on TikTok below at the location on Sunset Blvd in Hollywood (near the Chateau Marmont Hotel). If you want to encounter the animatronic band of fuzzy and totally friendly creatures from the game, you’ll have to visit Universal Studios Hollywood Halloween Horror Nights, there’s a walk-through in the DreamWorks theater lobby that’s been taken over by Blumhouse which features the real Jim ...
