Ionization experiments with benzene and similar organic molecules show evidence for short-lived electronic couplings, which resemble the Cooper pairs that carry current in superconductors.

Simulations on neural networks show that one single neuronal spike in a sequence of billions can affect how information is processed.

Intertwined loops of DNA can stably bind tiny particles together, giving researchers a new tool for coaxing particles into larger assemblies.

Tubulelike structures form when multiple nanoparticles adhere to the inner or outer surfaces of a spherical membrane.

Snapshots of a molecule dissociating into atomic fragments are captured with x-ray laser pulses.

A quantum twist on digital holography offers improved imaging and the chance to reach new and difficult wavelength regions.

A theoretical model of sunspots shows that their occasional disappearance may be due to a combination of fluctuations in the Sun’s polar magnetic field and outer layer flows.

The protein shells surrounding large viruses have built-in tension that determines their shapes.

Experimental data in combination with calculations show why some organic semiconductors have intrinsically different mobilities for electrons and holes.

A carefully prepared light beam can either push or pull tiny particles, like the much larger tractor beams of science fiction.

First-principles calculations predict a new class of ferroelectrics.

Cosmic rays may be used to capture images of damaged reactors at the Fukushima power plant in Japan.

New calculations of core-collapse supernovae show how bizarre nuclear structures—called pasta—develop in the dense core of a dying star.

Frictional forces between surfaces coated with charged polymers can be adjusted with external electric fields.

An improved equation for electrochemical cells accurately captures processes in desalination and generation of electricity from salt gradients in the ocean.

Existing or planned electron accelerators may be able to see the breakdown of general relativity.

A proposed experiment could, over several years of operation, test the suspicion that the three known flavors of neutrinos sometimes transform into other, undetectable types.

Experiments show that normally transparent nanorods can absorb or reflect nearly 100% of light at a specific wavelength when the rods are arranged in a periodic two-dimensional array.

The quantum states of light emitted by quantum dots stand up to the rigors of frequency conversion.
