It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
Published Forest restoration can boost people, nature and climate simultaneously
(via sciencedaily.com) Original source Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Wearable display tech: Full-color fiber LEDs based on perovskite quantum wires
(via sciencedaily.com) Original source A research team has developed full-color fiber light-emitting diodes utilizing perovskite quantum wires (PeQWs), paving the way for innovative wearable lighting and display devices.
Published Engineers bring efficient optical neural networks into focus
(via sciencedaily.com) Original source Researchers have published a programmable framework that overcomes a key computational bottleneck of optics-based artificial intelligence systems. In a series of image classification experiments, they used scattered light from a low-power laser to perform accurate, scalable computations using a fraction of the energy of electronics.
Published Glossy black-cockatoos prefer the fruits of ancient rocks
(via sciencedaily.com) Original source New research has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils.
Published Nature at risk in the hunt for the perfect selfie
(via sciencedaily.com) Original source The need for a dramatic selfie or the perfect landscape photo is proving detrimental to nature, a new research collaboration has found.
Published 3D laser printing with bioinks from microalgae
(via sciencedaily.com) Original source Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
Published Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity
(via sciencedaily.com) Original source A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
Published Unlocking the secrets of salt stress tolerance in wild tomatoes
(via sciencedaily.com) Original source As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
Published Discovering how plants make life-and-death decisions
(via sciencedaily.com) Original source Researchers have discovered two proteins that work in tandem to control an important response to cell stress.
Published Lemurs use long-term memory, smell, and social cues to find food
(via sciencedaily.com) Original source How do foraging animals find their food? A new study shows that lemurs use smell, social cues, and long-term memory to locate hidden fruit -- a combination of factors that may have deep evolutionary roots.
Published Plants offer fruit to insects to disperse dust-like seeds
(via sciencedaily.com) Original source Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.
Published Stacking molecules like plates improves organic solar device performance
(via sciencedaily.com) Original source Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
