In a recent study, researchers share their novel work on coupling free electrons with nonlinear optical states investigate, leveraging microcomb generation in photonic chip-based, high-quality-factor microresonators. They also highlight other technologies, including attosecond electron microscopy via free-electron homodyne detection, probing polariton wavepackets with free-electron resonant interferometry, generation and characterization of chiral electron coils, and ultrafast Kapitza-Dirac effect.

Researchers have developed a photonic transformer chip that runs on optical interference instead of electronic multiplication. The chip introduces a novel Kramers-Kronig attention mechanism, eliminating the need for SoftMax activation and supporting fully dynamic inputs. It achieves 94% accuracy on MNIST, with potential throughput exceeding 200 POPS and energy efficiency over 500 TOPS/W—ushering in a new paradigm for energy-efficient, high-speed AI.

Lipids are not just energy sources and structural components of cell membranes – they also act as molecules that transmit signals within and between cells. A new Koselleck Project at the Institute of Pharmaceutical Chemistry at Goethe University Frankfurt and the Max Planck Institute for Heart and Lung Research focuses on certain products derived from arachidonic acid. These products exhibit beneficial effects in cardiovascular diseases as well as in Alzheimer’s dementia and chronic pain.

The reticular architecture of metal-organic frameworks (MOFs) enables not only systematic but also creative tuning of their functionalities. A recent study involving forty structurally related MOFs demonstrated how to precisely integrate and regulate two types of electrochromic cores within the MOF architectures through mild linker modifications and straightforward crystal engineering. The underlying logic is reminiscent of a conventional color palette—yet elevated to molecular-level precision, offering promising prospects for future electronic applications.

Researchers at Yonsei University developed a fluoride-based solid electrolyte (LiCl–4Li₂TiF₆) that enables all-solid-state batteries to operate safely beyond 5 volts, overcoming a major voltage stability barrier. The innovation enhances ionic conductivity, prevents interfacial degradation, and achieves record energy density. Its compatibility with cost-effective materials makes it promising for next-generation electric vehicles and renewable energy storage, marking a paradigm shift in battery technology.
