Published A liquid crystal source of photon pairs



Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Researchers have demonstrated, for the first time, SPDC in a liquid crystal. The results open a path to a new generation of quantum sources: efficient and electric-field tunable.
Published Novel insights into fluorescent 'dark states' illuminate ways forward for improved imaging



Scientists address decades-long problem in the field of single-molecule fluorescence resonance energy transfer, paving the way for more accurate experiments.
Published New fabric makes urban heat islands more bearable



Researchers detail a new wearable fabric that can help urban residents survive the worst impacts of massive heat caused by global climate change, with applications in clothing, building and car design, and food storage. By addressing both direct solar heating and the thermal radiation emitting from pavement and buildings in urban heat islands, the material kept 2.3 degrees Celsius (4.1 degrees Fahrenheit) cooler than the broadband emitter fabric used for outdoor endurance sports and 8.9 degrees Celsius (16 degrees Fahrenheit) cooler than the commercialized silk commonly used for shirts, dresses and other summer clothing.
Published Can engineered plants help make baby formula as nutritious as breast milk?



New research may help close the nutrition gap between infant formula and human breast milk. The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.
Published Pair plasmas found in deep space can now be generated in the lab



Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
Published The scary, yet promising world of phages, the pathogen's pathogen



Researchers are unlocking the mystery of how bacteria harness viruses to wipe out the competition. The answers could help spur the development of alternatives to antibiotics.
Published Nanosized blocks spontaneously assemble in water to create tiny floating checkerboards



Researchers have engineered nanosized cubes that spontaneously form a two-dimensional checkerboard pattern when dropped on the surface of water. The work presents a simple approach to create complex nanostructures through a technique called self-assembly.
Published Researchers leverage inkjet printing to make a portable multispectral 3D camera



Researchers have used inkjet printing to create a compact multispectral version of a light field camera. The camera, which fits in the palm of the hand, could be useful for many applications including autonomous driving, classification of recycled materials and remote sensing.
Published Scientists adapt astronomy method to unblur microscopy images



Researchers have adapted a class of techniques employed in astronomy to unblur images of far-away galaxies for use in the life sciences, providing biologists with a faster and cheaper way to get clearer and sharper microscopy images.
Published Quantum dots and metasurfaces: Deep connections in the nano world



A team has developed printable, highly efficient light-emitting metasurfaces.
Published Humans are the elephant in the room where conservation is debated



Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Are plants intelligent? It depends on the definition



Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?
Published Scientists engineer yellow-seeded camelina with high oil output



Using tools of modern genetics, plant biochemists have produced a new high-yielding oilseed crop variety -- a yellow-seeded variety of Camelina sativa, a close relative of canola, that accumulates 21.4% more oil than ordinary camelina.
Published Specialist and migratory birds at greater risk under climate change



Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published New technique could help build quantum computers of the future



Researchers have demonstrated a new method that could enable the large-scale manufacturing of optical qubits. The advance could bring us closer to a scalable quantum computer.
Published Switching nanomagnets using infrared lasers



Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.
Published New computer vision method helps speed up screening of electronic materials



A new computer vision technique developed by engineers significantly speeds up the characterization of newly synthesized electronic materials. Such materials might be used in novel solar cells, transistors, LEDs, and batteries.
Published Researchers engineer new approach for controlling thermal emission



If a material absorbs light, it will heat up. That heat must go somewhere, and the ability to control where and how much heat is emitted can protect or even hide such devices as satellites. An international team of researchers has published a novel method for controlling this thermal emission in Science.
Published Researchers demonstrate the first chip-based 3D printer



Researchers have demonstrated the first chip-based 3D printer, a tiny device that emits reconfigurable beams of visible light into a well of resin that rapidly cures into a solid shape. The advance could enable a 3D printer small enough to fit in the palm of a person's hand.
Published Miniaturizing a laser on a photonic chip



Scientists have successfully miniaturized a powerful erbium-based biber laser on a silicon-nitride photonic chip. Since typical erbium-based fiber lasers are large and difficult to scale down, the breakthrough promises major advances in optical communications and sensing technologies.
