The composition of cells in tissues can be found using statistical fluctuations of cell types.

Shaken or stirred? Suspended beads stir themselves when shaken in a new experiment using magnetic levitation.

The so-far disappointingly short lifetime of spin-polarized currents in graphene may be the result of magnetic defects.

Germanium-76 is a rare example of a nucleus with a triaxial symmetry in its ground state.

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

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 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.

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.

Laser light scattered from a single atom undergoes large optical phase shifts that may be useful in imaging and quantum information transmission.

The surprisingly complex behavior of three gravitationally attracted bodies includes several previously unknown periodic orbits.

A strongly driven single-ion qubit offers a method for performing spectrum analysis with high resolution.

The excitation spectrum of artificial spin ices can be used to identify defects that behave as magnetic monopoles.

Calculations suggest that there are ways to drive spasers—the nanoplasmonic counterparts of lasers—by standard electrical currents.

No cause for alarm, but new simulations show that less energy than previously thought is needed to form a black hole in a particle collision.
