Scientists map world first 3D image of cancer-spreading protein
Scientists at Griffith University's Institute for Glycomics released the world's first 3-D image of a protein that is linked to the spread of cancer. Where before scientists had to guess what the structure looked like, now they have a clear 3-D model meaning they can see how it works and develop targeted medicines to stop it before the protein can make matters worse. It was mapped using a technique called X-Ray crystallography and the team, lead by the institute's Director Professor Mark von Itzstein, notes that the image is so well defined that it shows both the structure of the overall protein as well as atomic-level details.
Researchers capture a single atom's shadow, has implications for quantum computers
A very small atom can cast a very large shadow. Well, not literally, but figuratively. Researchers at Griffith University have managed to snap the first image of a single atom's shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge. The team of scientists blasted a Ytterbium atom suspended in air with a laser beam. Using a Fresnel lens, they were able to snap a photograph of the dark spot left in the atom's wake as the laser passed over it. The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information. Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations. The research could even be applied to seemingly mundane and established fields like X-Ray imaging, by enabling us to find the proper intensity levels to produce a quality image while minimizing damage to cells.
