Vibrational resonances provide a sensitive probe into the materials’ thermodynamic properties.

A scanning probe technique simultaneously maps the topographic structure and vibrational spectra inside a single molecule.

A high-resolution crystallographic structure reveals why aquaporin proteins are permeable to water but not to protons.

New loan guarantees for spurring development of technologies to control carbon emissions are not likely to help utilities cut their CO₂ output in the short term.

Nine months of data from the world’s deepest observatory agree with lab measurements on a controversial quake parameter.

Lasers could eventually replace accelerator mass spectrometry for many biomedical applications, but they haven’t yet.

For evolving astrophysical accretion disks to concentrate their mass and still conserve angular momentum, turbulent flows are crucial. Those flows cannot be directly observed, so to understand them better physicists are creating them in modest-sized laboratory experiments.

Half a century after the first efforts to drill through oceanic crust failed, geoscientists are ready to try again.

Programs that augment the core physics curriculum with real-world business skills could hold the key to the discipline’s future growth.

The stains left by drying coffee would look quite different—both microscopically and macroscopically—if the suspended grounds weren’t roughly spherical.
