Since their discovery, the historically and biblically hugely important Dead Sea Scrolls have transformed our understanding of Jewish and Christian origins. However, while the general date of the scrolls is from the third century BCE until the second century CE, individual manuscripts thus far could not be securely dated.

Now, by combining radiocarbon dating, paleography, and , an international team of researchers led by the University of Groningen has developed a date-prediction model, called Enoch, that provides much more accurate date estimates for individual manuscripts on empirical grounds.

Using this model, the researchers demonstrate that many Dead Sea Scrolls are older than previously thought. And for the first time, they establish that two biblical scroll fragments come from the time of their presumed biblical authors. They present their results in the journal PLOS One.

A trio of AI researchers at KAIST AI, in Korea, has developed what they call a Chain-of-Zoom framework that allows the generation of extreme super-resolution imagery using existing super-resolution models without the need for retraining.

In their study published on the arXiv preprint server, Bryan Sangwoo Kim, Jeongsol Kim, and Jong Chul Ye broke down the process of zooming in on an image and then used an existing super-resolution model at each step to refine the image, resulting in incremental improvements in resolution.

The team in Korea began by noting that existing frameworks for improving the resolution of pictures tend to use interpolation or regression when zooming, resulting in blurry imagery. To overcome these problems, they took a new approach—using a stepwise zooming process, in which subsequent steps improve on those that came before.

Contrary to the popular saying, rules aren’t meant to be broken, as they are foundational to society and exist to uphold safety, fairness and order in the face of chaos. The collective benefits of rule-following are well established, but individual incentives are often unclear. Yet, people still comply, and the reasons why are pieces of a puzzle that researchers of human behavior have been trying to piece together for years.

A recent study published in Nature Human Behavior explored the behavioral principles behind why people follow rules using a newly designed framework called CRISP. A series of four online experiments based on the framework involving 14,034 English-speaking participants, revealed that the majority (55%–70%) of participants chose to follow arbitrary rules—even when the compliance was costly, they were anonymous and violations had no adverse effects on others.

This proposed CRISP system explains rule conformity © as a function of four components: R—intrinsic respect for rules, independent of others’ behavior; I—extrinsic incentives, such as the threat of punishment for breaking rules; S—social expectations about whether others will follow the rule or believe one should; and P—, which matter when rule-following affects the well-being of others.

The extraction of work (i.e., usable energy) from quantum processes is a key focus of quantum thermodynamics research, which explores the application of thermodynamics laws to quantum systems. Meanwhile, other quantum physics research has been investigating the non-Markovian dynamics of open quantum systems, which entail the influence of past states on the systems’ future evolution.

Researchers at the University of Nottingham and University of São Paulo have introduced a general and rigorous framework that bridges and non-Markovian dynamics, showing that the latter could serve as a resource that can be exploited to enhance the extraction of work from quantum processes.

Their paper, published in Physical Review Letters, could open new possibilities for the future development of quantum technologies.

Boise State University researchers have developed a new technique and platform to communicate with cells and help drive them toward cartilage formation. Their work leverages a 3D biocompatible form of carbon known as graphene foam and is featured on the cover of Applied Materials and Interfaces.

In this work, the researchers aim to develop new techniques and materials that can hopefully lead to new treatments for osteoarthritis through . Osteoarthritis is driven by the irreversible degradation of hyaline cartilage in the joints, which eventually leads to pain and disability, with complete joint replacement being the standard clinical treatment. Using custom-designed and 3D-printed bioreactors with electrical feedthroughs, they were able to deliver brief daily electrical impulses to cells being cultured on 3D graphene foam.

The researchers discovered that applying direct to ATDC5 cells adhered to the 3D graphene foam bioscaffolds significantly strengthens their and improves —key metrics for achieving lab-grown cartilage. ATDC5 cells are a murine chondrogenic progenitor cell line well studied as a model for cartilage tissue engineering.

An international research collaboration featuring scientists from the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory has discovered a fundamental universal principle that governs how microscopic whirlpools interact, collide and transform within quantum fluids, which also has implications for understanding fluids that behave according to classical physics.

The study, which was published in the Proceedings of the National Academy of Sciences, revealed new insights into vortex dynamics within , a remarkable liquid that exhibits zero-resistance flow at temperatures approaching absolute zero. The research demonstrates that when these quantum vortices intersect and reconnect, they separate faster than their initial approach velocity, creating bursts of energy that characterize turbulence in both quantum and classical fluids.

“Superfluids offer a uniquely clear perspective on turbulence,” said FAMU-FSU College of Engineering Professor Wei Guo, a study co-author. “We’re beginning to understand the universal physics that connects quantum and classical worlds, and that’s an exciting frontier for both science and technology.”

Boise State University researchers have unveiled a cutting-edge approach to manufacturing flexible hybrid circuits—reducing costs, waste, and environmental impact. Their work leverages the properties of laser-induced graphene and was recently featured on the cover of Advanced Materials Technologies.

Laser-induced graphene uses a single-step laser manufacturing process that converts carbon-rich materials into a 3-dimensional conductive and porous structure with some regions of atomically thin graphene. This technique is scalable, cost-effective, and patternable, making it ideal for applications in electronics, sensing, and energy storage.

In this work, the researchers used palladium (Pd) nanoparticles embedded in a polymer matrix to form Pd functionalized laser-induced graphene. These Pd nanoparticles act as seed crystals for the electroless deposition of copper on the LIG scaffold, thus forming copper interconnects for flexible printed circuit boards (f-PCBs) through a laser-enabled additive manufacturing process.

Everything in nature has a geometric pattern—from the tiger’s stripes and spirals in flowers to the unique fingerprints of each human being. While these patterns are sometimes symmetrical, most of such patterns lack symmetry, which leaves us with one major question: How do such unsymmetrical patterns emerge in nature?

Studies report that drying environments cause water evaporation and can lead to the formation of asymmetric patterns during biological growth through a phenomenon called “ breaking.” Although reported through mathematical studies, these studies lack physical-chemical experiments that replicate this phenomenon.

A recent study at the Japan Advanced Institute of Science and Technology (JAIST), led by Associate Professor Kosuke Okeyoshi and doctoral student Thi Kim Loc Nguyen, uncovers the mechanisms behind symmetry breaking during a process called meniscus splitting in evaporating polymer solutions. The findings of the study were published in Advanced Science on June 3, 2025.

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics in a two-dimensional analog quantum simulator for the first time. The study, published in Nature, opens up new possibilities for research into fundamental physical phenomena.

String breaking occurs when the string between two strongly bound particles, such as a quark-antiquark pair, breaks and new particles are created. This concept is central to understanding the that occur in (QCD), the theory that describes the binding of quarks in protons and neutrons.

String breaking is extremely difficult to observe experimentally, as it only occurs in nature under extreme conditions. The recent work by scientists from the Universities of Innsbruck and Harvard, the ÖAW-Institute for Quantum Optics and Quantum Information (IQOQI) and the quantum computer company QuEra shows for the first time how this phenomenon can be reproduced in an analog quantum .

For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996.

The radioactive decay of atomic nuclei has been one of the keystones of nuclear physics since the beginning of nuclear research. Now the heaviest nucleus decaying via proton emission has been measured in the Accelerator Laboratory of the University of Jyväskylä, Finland. The was written as part of an international research collaboration involving experts in theoretical nuclear physics and published in Nature Communications on 29 May 2025.

“Proton emission is a rare form of radioactive decay, in which the nucleus emits a proton to take a step toward stability,” says Doctoral Researcher Henna Kokkonen from the University of Jyväskylä
