Seeing More with a Needle-Shaped Laser


Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, and his research team show how they developed a new variant of photoacoustic microscopy (PAM) called needle-shaped beam photoacoustic microscopy (NB-PAM). NB-PAM has a depth of field nearly 14 times greater than what was achievable before. [Caltech story]

Physicists Observe Wormhole Dynamics Using a Quantum Computer


Scientists have, for the first time, developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole. The research is a step toward studying quantum gravity in the lab. [Caltech story]

New Process Allows 3-D Printing of Microscale Metallic Parts


Engineers at Caltech have developed a method for 3-D printing pure and multicomponent metals, at a resolution that is, in some cases, an order of magnitude smaller than previously possible. "We had to develop a new way of doing it, and we couldn't rely on heat to build our structures," says Max Saccone. [Caltech story]

Professor John Sader Elected to the Australian Academy of Science


John Sader, Research Professor of Aerospace and Applied Physics, has been elected to the Australian Academy of Science. Sader developed pioneering measurement techniques that revolutionized the characterization of materials using Atomic Force Microscopy (AFM). The Sader Method is an international standard for AFM calibration, as is the Sader-Jarvis Method for atomically resolved AFM measurements.

Pushing the Boundaries of Fluid Equations


Thomas Hou, Charles Lee Powell Professor of Applied and Computational Mathematics, and Jiajie Chen (PhD '22) of New York University's Courant Institute, provide a proof that resolves a longstanding open problem for the so-called 3D Euler singularity. Hou and colleagues' combined effort in proving the existence of blowup with the 3D Euler equation is a major breakthrough in its own right, but also represents a huge leap forward in tackling the Navier-Stokes Millennium Problem. If the Navier–Stokes equations could also blow up, it would mean something is awry with one of the most fundamental equations used to describe nature. [Caltech story]
