Quantum entanglement, a core concept of quantum mechanics, is a key resource for quantum information science and is widely used in quantum communication, quantum computing, and other fields. However, traditional quantum entanglement is mostly based on a single degree of freedom, which limits the efficiency and capacity of quantum information processing. In recent years, progress has been made in the study of quantum entanglement with multiple degrees of freedom, but it remains challenging to generate and control complex quantum entangled states in a more compact and flexible manner. Metasurfaces, as artificial two-dimensional materials, can precisely control the amplitude, phase, and polarization of light to achieve complex optical functions, offering a new way to manipulate quantum entanglement flexibly. Currently, the potential of metasurfaces in the field of quantum entanglement has not been fully explored.

A collaborative research team from Kanazawa University, the Indian Institute of Technology Hyderabad, and the University of Strathclyde has developed a novel method for forming high-performance high-entropy alloy (HEA) films on various surfaces—without the need for costly alloy targets. By using a proprietary rotating target composed of multiple pure metal segments and pulsed laser deposition (PLD) technology, the team successfully demonstrated a cost-effective and versatile approach to HEA film fabrication.

A new wastewater treatment system developed by RMIT University researchers could help prevent fatbergs – solid masses of fat, oil and grease (FOG) that clog sewers and cost water utilities globally billions to remove each year.

A new scientific discovery at the University of Missouri could lead to the identification of a biomarker for both earlier detection and treatment of a devastating eye disease.

As the new school year arrives, Pennsylvania teachers are knee-deep in lesson planning while preparing for a major shift: implementing the state's STEELS standards—which emphasize science, technology, engineering, environmental literacy, and sustainability—in time for full integration into K-12 classrooms by the start of the 2025-26 school year. To support educators already stretched for time and resources, especially those new to teaching computer science, Lehigh University is introducing the Lehigh K-12 Computer Science STEELS Toolkit: a suite of flexible, free enrichment activities designed and tested by undergraduate students and partnering teachers at local schools for use in elementary and secondary classrooms.

A recent Illinois law went into effect requiring public high schools to teach at least one unit on media literacy. However, a new study led by University of Illinois Urbana-Champaign researchers in collaboration with Northwestern University found that instruction varies widely across the state's schools and is fraught with digital divides associated with teachers' lack of familiarity with the platforms used by teens, teachers' academic background and local politics.
