Removing the charged layer around a particle allows detailed measurements of its motion in an electric field.

The LiHe van der Waals molecule has been produced and spectroscopically detected and its binding energy found to only suffice to stabilize a single rotationless vibrational state.

A model for analyzing materials using ultrasound shows that the seemingly random fluctuations in the data may contain information about the microscopic structure.

When rapidly deformed, a suspension of cornstarch in water not only becomes stiff like a solid but also fractures like one.

Hairlike sensory cells in our ears may detect weak auditory signals through a synchronization process, according to new experiments.

Femtosecond laser spectroscopy can identify otherwise inaccessible precursors in photoinduced chemical reactions.

The first results from the space-borne Alpha Magnetic Spectrometer confirm an unexplained excess of high-energy positrons in Earth-bound cosmic rays.

A major source of energy loss in laser-driven fusion could be remedied with the use of optical elements called zooming-phase plates.

Combining two spin-dependent effects generates a microwave signal that can be easily read to study the magnetization dynamics in a device with novel geometry.

New theory and experiments explain why the lengthy strands that dangle from a spoon of honey can get so long without breaking up.

The IceCube neutrino telescope reports its most extensive search for neutrinos produced by dark matter annihilations in the Sun.

Metal nanorods grown by physical vapor deposition can be fabricated with a much narrower diameter than previously thought, potentially enabling the design of more efficient catalysts.

When exposed to light, swimming microalgae converge to the center of a pipe—a behavior that could prove advantageous for certain industrial uses of these organisms.

Defects in diamond could be used to engineer portable timekeeping devices as precise as modern atomic clocks, according to a new theoretical proposal.

Optical experiments let researchers fully characterize the quantum transformations corresponding to photon creation and annihilation operators.

The ATRAP Collaboration has measured the magnetic moment of the antiproton more precisely than ever before, allowing a new test of $CPT$ symmetry.

New search for hypothetical particle focuses on old rocks where monopole abundance should be higher.

An experimental team provides new supporting evidence for a self-annihilating quasiparticle inside specially prepared superconductors.

Shape-preserving waves that create a depression in the surrounding medium are observed in water for the first time.
