The enigmatic Philistine culture, which flourished during the Iron Age (ca. 1200-604 BCE), profoundly affected the southern Levant's cultural history, agronomy, and dietary customs.
While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. The study by Frumin et al. on "Plant-Related Philistine Ritual Practices at Biblical Gath," recently published in Scientific Reports by researchers at Bar-Ilan University, contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs – their temple food ingredients, timing of ceremonies, and plants for temple decoration.

Do you know someone who knows someone? We have all played this game, often to be amazed that despite the extreme scale of human society, random people can be linked through very small chains of acquaintances -- typically, around six. Recently, a group of researchers from across the globe discovered that this magic of six degrees can be explained mathematically. The intriguing phenomenon, they show, is linked to another social experience we all know too well -- the struggle of cost vs. benefit in establishing new social ties.

A project led by a group of researchers from Israel's Bar-Ilan University, in collaboration with TII - the Quantum Research Center in Abu Dhabi, United Arab Emirates, is advancing quantum computing by improving the performance of superconducting qubits, the basic computation units of a superconducting quantum processor. The improved qubit, called a tunable superconducting flux qubit, is a micron-sized superconducting loop where electrical current can flow clockwise or counterclockwise, or in a quantum superposition of both directions.
A single species invades an ecosystem causing its collapse. A cyberattack on the power system causes a major breakdown. These type of events are always on our mind, yet they rarely result in such significant consequences. So how is it that these systems are so stable and resilient that they can withstand such external disruptions? Indeed, these systems lack a central design or blueprint, and still, they exhibit exceptionally reliable functionality.
The key question driving new research published today in Scientific Reports is whether efficient learning of non-trivial classification tasks can be achieved using brain-inspired shallow feedforward networks, while potentially requiring less computational complexity.

One study, led by the Toker group from Bar-Ilan University in Israel, observed peptide bond formation in clusters containing four serine dipeptides that were heated up by collisions. However, they found no evidence for the same process occurring in serine clusters. In that work they concluded that if two serine molecules can bind together to form a dipeptide, then the next stages of polymerization could probably occur readily.
Can the brain, with its limited realization of precise mathematical operations, compete with advanced artificial intelligence systems implemented on fast and parallel computers? From our daily experience we know that for many tasks the answer is yes! Why is this and, given this affirmative answer, can one build a new type of efficient artificial intelligence inspired by the brain? In an article published today in Scientific Reports, researchers from Bar-Ilan University in Israel solve this puzzle.

Dr. Michael Stern and co-workers from the Department of Physics and Quantum Entanglement Science and Technology (QUEST) Center at Bar-Ilan University in Israel are attempting to build superconducting processors based on a type of circuit called superconducting flux qubits. A flux qubit is a micron-sized superconducting loop where electrical current can flow clockwise or counter-clockwise, or in a quantum superposition of both directions. Contrary to transmon qubits, these flux qubits are highly non-linear objects and can thus be manipulated on very short time scales with high fidelity. The main drawback of flux qubits, however, is that they are particularly difficult to control and to fabricate. This leads to sizeable irreproducibility and has limited their use in the industry until now to quantum annealing optimization processes such as the ones realized by D-Wave.
Using a novel fabrication technique and state-of the-art equipment, a group led by Dr. Stern, in collaboration with Pr
Bar-Ilan University and the Technion – Israel Institute of Technology have won a call published by the Israel Ministry of Energy for the establishment of a national research institute in the field of energy storage.
The precise relationship between vaccine hesitancy and COVID-19 vaccination side effects has not previously been explored in vaccinated persons. A fundamental question arises in regard to the directionality of this vaccine hesitancy-vaccine side effect link, namely which variable predicts which. One possibility is that side effects from an earlier dose predict one’s vaccine hesitancy towards a later dose. Alternatively, one’s psychological negativity (hesitancy) towards an earlier dose could predict subsequent side effects from a later vaccination dose. The latter direction reflects a Nocebo effect, i.e., side effects driven by psychological factors rather than by an active treatment component. Results showed only the latter direction to be true. Namely, only earlier vaccine hesitancy towards the second COVID-19 dose predicted subsequent nocebo side-effects following the booster vaccination. To put this in perspective up to 16% of one’s vaccine side effects were explained by earlier va
When neurons are damaged by degenerative disease or injury, they have little, if any, ability to heal on their own. Restoring neural networks and their normal function is therefore a significant challenge in the field of tissue engineering. Prof. Orit Shefi and doctoral student Reut Plen from the Kofkin Faculty of Engineering at Bar-Ilan University have developed a novel technique to overcome this challenge using nanotechnology and magnetic manipulations, one of the most innovative approaches to creating neural networks.

In an article published today in Scientific Reports (https://www.nature.com/articles/s41598-022-10466-8), researchers from Bar-Ilan University in Israel reveal that the brain learns completely differently than has been assumed since the 20th century. The new experimental observations suggest that learning is mainly performed in neuronal dendritic trees, where the trunk and branches of the tree modify their strength, as opposed to modifying solely the strength of the synapses (dendritic leaves), as was previously thought. These observations also indicate that the neuron is actually a much more complex, dynamic and computational element than a binary element that can fire or not. Just one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons and synapses. The new demonstration of efficient learning on dendritic trees calls for new approaches in brain research, as well as for the generation

The development was recently reported in the Journal of Clinical Investigation.
