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

Enhancing drug testing with human body-on-chip systems

The U.S. Food and Drug Administration (FDA) approves only 13.8% of all tested drugs, and these numbers are even lower in “orphan” diseases that affect relatively few people. Part of the problem lies in the imperfect nature of preclinical drug testing that aims to exclude toxic effects and predetermine concentrations and administration routes before drug… Read More

Study reveals two writers penned landmark inscriptions in eighth-century BCE Samaria

The ancient Samaria ostraca — eighth-century BCE ink-on-clay inscriptions unearthed at the beginning of the 20th century in Samaria, the capital of the biblical kingdom of Israel — are among the earliest collections of ancient Hebrew writings ever discovered. But despite a century of research, major aspects of the ostraca remain in dispute, including their… Read More

Siblings of children with intellectual disabilities score high on empathy, teaching and closeness

The sibling relationship is the longest most people will enjoy in their lifetimes and is central to the everyday lives of children. A new Tel Aviv University and University of Haifa study finds that relationships between children and their siblings with intellectual disabilities are more positive than those between typically developing siblings. The research examines the relationships… Read More

Fibroblasts involved in healing spur tumor growth in cancer

The connective tissue cells known as fibroblasts are vitally important for our recovery from injury. Sensing tissue damage, they gravitate to the site of a wound, instigating an inflammatory response that mends damaged tissue. A new Tel Aviv University study published in Nature Communications on September 26 finds that fibroblasts also play a devastating role… Read More

Tiny insects become “visible” to bats when they swarm

Bats use echolocation to hunt insects, many of which fly in swarms. In this process, bats emit a sound signal that bounces off the target object, revealing its location. Smaller insects like mosquitos are individually hard to detect through echolocation, but a new Tel Aviv University study reveals that they become perceptible when they gather… Read More
