Elusive state of superconducting matter discovered after 50 years
Scientists at the US Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964 -- a 'Cooper pair density wave.' The discovery, described in a paper published online April 13, 2016, in Nature, may provide key insights into the workings of high-temperature superconductors.

Quantum dots enhance light-to-current conversion in layered semiconductors
Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).

Insulator-superconductor transition of copper-oxide compound studied in fine detail
Using a highly controlled deposition technique, scientists from the US Department of Energy's (DOE) Brookhaven National Laboratory have synthesized ultrathin films containing multiple samples of a copper-oxide compound to study the compound's electronic behavior at near absolute zero, or minus 459 degrees Fahrenheit. Their study revealed that fluctuations in the distribution of electrical charges at near-absolute-zero temperature compete with superconductivity.

A view of the colorful microcosm within a proton
By analyzing the particle debris emitted from collisions of polarized protons at the Relativistic Heavy Ion Collider, scientists say they've found a new way to glimpse the microcosm within these building blocks of matter. They've measured a key effect of the so-called color interaction -- the basis for the strong nuclear force that binds quarks within the proton.

Synchronized leaf aging in the Amazon responsible for seasonal increases in photosynthesis
High-tech photography in the Amazon reveals that young leaves grow in at the same times as older ones perish, in strong contrast to temperate forests in North America or Europe, resulting in seasonal increases in photosynthesis that must be taken into account to build more accurate climate models.

Scientists propose 'pumpjack' mechanism for splitting and copying DNA
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.

Chiral magnetic effect generates quantum current
Scientists at the US Department of Energy's Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-"handed" particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity-the ability of some materials to carry current with no energy loss.

Scientists guide gold nanoparticles to form 'diamond' superlattices
Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement may open a path to new materials that take advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, color-changing materials, and lightweight yet tough materials.

RHIC particle smashups find that shape matters
Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' at Brookhaven National Laboratory -- scientists have come to a new understanding of how particles are produced in these collisions. This understanding represents a paradigm shift consistent with the presence of a saturated state of gluons, super-dense fields of the glue-like particles that bind the building blocks of ordinary matter.

New clues for battling botulism
Scientists have discovered new details about how 'cloaking' proteins protect the toxin that causes botulism, a fatal disease caused most commonly by consuming improperly canned foods. That knowledge and the cloaking proteins themselves might now be turned against the toxin -- the deadliest known to humankind.

Physicists measure force that makes antimatter stick together
Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and will publish in Nature.
