TAU-Led International Collaboration: High Variability Is Consequence of Complex Data Workflows, Finds Nature Study

A new Tel Aviv University-led study published on May 20 in Nature offers new evidence that the complexity of contemporary analytical methods in science contributes to the variability of research outcomes. Previous studies in the fields of psychology, cancer biology and behavioral economics revealed many failures in the attempt to reproduce methodologies and mirror results…. Read More

TAU researchers demonstrate optical backflow of light

Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated successfully in any experiment — until now. “This ‘backflow’ phenomenon is quite delicate and requires exquisite control over the state of a particle,… Read More

Induced flaws in metamaterials can produce useful textures and behavior

While a piece of paper is usually flat and floppy, the same piece of paper crumpled into a wad is stiff and round. This demonstrates that scrunching changes the texture and behavior of precisely the same material — paper. A new Tel Aviv University study shows how induced defects in metamaterials — artificial materials the properties of… Read More

Your zip software can calculate the complex physical quantity called entropy

Entropy, a measure of the molecular disorder or randomness of a system, is critical to understanding a system’s physical composition. In complex physical systems, the interaction of internal elements is unavoidable, rendering entropy calculation a computationally demanding, and often impractical, task. The tendency of a properly folded protein to unravel, for example, can be predicted… Read More

TAU and Technion researchers wrest control of one of world’s most secure PLCs

Cybersecurity researchers at Tel Aviv University and the Technion Institute of Technology have discovered critical vulnerabilities in the Siemens S7 Simatic programmable logic controller (PLC), one of the world’s most secure PLCs that are used to run industrial processes. Prof. Avishai Wool and M.Sc student Uriel Malin of TAU’s School of Electrical Engineering worked together… Read More

Breakthrough in laser technology lights the way for improved displays and illumination

Lead-halide perovskites are considered one of the most promising materials for the production of the lasers of the future. A new joint Tel Aviv University (TAU) and Karlsruhe Institute of Technology (KIT) study published in Nature Communications on February 28 demonstrates remarkable continuous lasing action in devices made from perovskites. “In contrast to previous studies… Read More

Low-bandwidth radar technology provides improved detection of objects

Radar technologies were originally designed to identify and track airborne military targets. Today they’re more often used to detect motor vehicles, weather formations and geological terrain. Until now, scientists have believed that radar accuracy and resolution are related to the range of frequencies or radio bandwidth used by the devices. But a new Tel Aviv… Read More
