Researchers from the University of Copenhagen have discovered an important phenomenon beneath the Arctic sea ice that was previously thought impossible. This phenomenon could have implications for the food chain and the carbon budget in the cold north.

Artificial intelligence (AI) data centers use huge amounts of electricity and face future risks from quantum computers that could break today’s encryption. To tackle this, researchers developed a new system that combines ultrafast data transmission with quantum key distribution for security. In tests, the system delivered data at terabit-per-second capacity with low power consumption, while generating secure encryption keys in real time, pointing to a promising path for the development of more efficient and secure data transmission systems to handle the surging demands of AI applications such as autonomous vehicles and large language models.

EPFL researchers have discovered that a droplet of liquid can bounce for several minutes – and perhaps indefinitely – over a vibrating solid surface. The seemingly simple observation has big implications for physics and chemistry.

In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists and engineers. Research published in Nature Physics reveals a previously hidden feature that could explain how and why enigmatic quantum phases emerge.

It's not all about energy: Electrons, which are given a sufficient amount of energy to leave a materiel do not necessarily manage to escape. They have to occupy certain "doorway states" to do that.

At the 2025 IAEA Fusion Energy Conference (FEC), the members of the EUROfusion Consortium and the ITER International Fusion Energy Organization have signed a high-level cooperation agreement to strengthen academic, scientific and technical collaboration in support of ITER’s mission.

The EUROfusion programme has long been focused on addressing the fundamental physics and technological gaps identified by ITER. This new cooperation agreement builds on that foundation to provide a complementary, fast-track framework to deliver agile, targeted solutions to some of ITER’s more immediate design and engineering challenges, particularly those arising from recent changes to its baseline.

Perovskite materials offer exceptional optoelectronic properties for photodetectors, but precise patterning is critical to optimize their performance. This review surveys five key patterning strategies—template-guided growth, inkjet printing, vapor deposition, seed-induced growth, and photolithography—highlighting their roles in controlling perovskite microstructures. The resulting patterned films enable high-sensitivity photodetectors across zero- to three-dimensional architectures, facilitating breakthroughs in flexible wearables and biomimetic vision systems. These advances pave the way for next-generation imaging, health monitoring, and human-machine interfaces.
