Finding order in disorder: A new mechanism that amplifies transverse electron transport

For decades, it has been widely believed that electrons move most efficiently in materials that are clean and highly ordered. Much like water flowing more easily through a smooth pipe, conventional wisdom has held that electrical transport improves as a material’s internal structure becomes more perfectly arranged. However, a recent study shows that the opposite can also be true. A research team at POSTECH in South Korea has discovered that engineered disorder can actually enhance electron transport. The work was conducted by Prof. Hyungyu ...

A much more sensitive fentanyl detection strip, thanks to physics

WASHINGTON, March 24, 2026 — Following the beginning of the COVID-19 outbreak, lateral flow assays (LFAs) — the category of test strips in which the presence or lack of a pink line indicates whether a specific molecule, like a drug or a virus, has been detected — became household items. Yet despite their ubiquity and decades of development, there has not been a quantitative, physics-grounded method for explaining the sensitivity and limits of LFAs to help guide their design. In Biophysics Reviews, by AIP Publishing, researchers from the University of California, San Diego developed a physics-based ...

Asymmetric laser pulses let scientists read molecular vibrations buried in metallic noise

By shaping a near-infrared laser pulse into a steep-rise, slow-decay waveform, researchers achieved tip-enhanced sum frequency generation spectroscopy that suppresses metallic background noise and detects weak vibrational signals with a 10-million-fold enhancement factor.

Sculpting the surface beneath a superconductor makes it work at higher temperatures and in strong magnetic fields

Instead of modifying a superconductor's chemistry, Chalmers University researchers engineered nanoscale ridges on the supporting substrate, enabling an ultrathin cuprate film to superconduct at higher temperatures and withstand strong magnetic fields - a new design principle for energy-efficient electronics.

Physicists detect electron scattering with spinning light for the first time

Tokyo Metropolitan University researchers have detected laser-assisted electron scattering using circularly polarized light for the first time - a technical milestone that could reveal how atomic-scale chirality affects electron behavior. The signal matched theoretical predictions from Kroll-Watson theory.

The 'Higgs boson of oxidation chemistry' has finally been seen at room temperature

Scientists at KTH Royal Institute of Technology and Kinetic Chemistry Research have made the first direct observation of tetroxides - fleeting, oxygen-rich molecules assumed to exist for 70 years but never seen - finding they survive 0.2 to 200 milliseconds in ordinary air.

Scanning 2,000 ants in a week: how a particle accelerator built a 3D insect library

Using a synchrotron particle accelerator, robotics, and AI, researchers scanned 2,000 ant specimens in one week -- a process that would have taken six years with conventional equipment. The resulting Antscan database, covering 800 species, is freely available and reveals internal anatomy at micrometer resolution.

Nearly half of adults over 65 improve in cognition or physical function over time

Tracking over 11,000 adults aged 65-plus for up to 12 years, Yale researchers found that 45% improved in cognition, walking speed, or both. Those who held more positive views about aging were significantly more likely to improve -- even after adjusting for health, education, and depression.
