Early Saturday morning, the School of Public and International Affairs (SPIA) at Princeton University was vandalized with red dye in the fountain and spray paint reading "Pretty Town Bloody Gown" on Robertson Hall. Princeton Israeli Apartheid Divest (PIAD) stated that the action was likely by an autonomous group pushing for university divestment from Israel, though PIAD did not coordinate the vandalism. This follows previous pro-Palestine and anti-Israel graffiti incidents on campus. The university has yet to comment.

Researchers at Princeton University have developed a new method for connecting distant quantum devices, a significant advancement for quantum communication networks. The technology uses telecom band light to efficiently transmit signals with minimal losses through optical fiber, overcoming a major obstacle in establishing resilient quantum communication networks. The study, published in Nature, details the innovative approach to constructing quantum repeaters, which involves using erbium ions emitting light at an optimal infrared wavelength. While this achievement represents a crucial milestone, further work is needed to enhance the storage duration of quantum states in the erbium ion’s spin, highlighting the ongoing pursuit of improvement in the dynamic quantum computing landscape.

Physicists have finally captured direct observational evidence of the Wigner crystal, a peculiar kind of matter proposed by Eugene Wigner 90 years ago, in which free electrons are forced together in a crystalline lattice due to their mutual repulsion. Using high-resolution scanning tunneling microscopy, a team of physicists from Princeton University observed the Wigner crystal in pristine graphene at extremely low temperatures and low densities, confirming its properties and revealing its novel quantum nature, including strong zero-point motion. This groundbreaking discovery provides the first direct images of the Wigner crystal and contradicts previous theories about its stability and density range.

Physicists at Princeton University have successfully visualized the Wigner crystal, a crystal made entirely of electrons, for the first time using a scanning tunneling microscope. This breakthrough confirms a 90-year-old theory proposed by Eugene Wigner and could lead to the discovery of new quantum phases of matter. The researchers used pristine graphene and low temperatures to directly image the crystal, observing its triangular configuration and its ability to transition into an electron liquid phase. They also discovered the quantum nature of the crystal, including the "zero-point" motion of electrons, and are now investigating how the crystal melts and transitions into other exotic liquid phases.

Physicists and engineers at Princeton University have built a twisting fusion reactor called a stellarator, named MUSE, using permanent magnets, which offers a potentially cost-effective method for constructing powerful machines. This new technique allows for quick testing of plasma confinement ideas and easy device construction. The use of permanent magnets eliminates the need for electric current to generate magnetic fields, making it easier for scientists to replicate experimental setups and perform high-temperature experiments, bringing us closer to the goal of usable and scalable fusion energy.

Renowned psychologist and Nobel prize winner Daniel Kahneman has passed away at the age of 90. His groundbreaking work in behavioural economics, particularly the theory that people's behavior is often based on instinct rather than rational decision-making, has had a profound impact on the social sciences. Kahneman's influential research earned him the Nobel memorial prize in economic sciences in 2002, and his bestselling book "Thinking, Fast and Slow" further solidified his legacy. Kahneman's contributions have left an indelible mark on the field of psychology and economics, and he will be greatly missed.
