Published Iceland's volcano eruptions may last decades
(via sciencedaily.com) Original source Scientists predict from geochemical data that Iceland is entering a new volcanic era that will last for decades, possibly centuries. Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.
Published An optical lens that senses gas
(via sciencedaily.com) Original source A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties of the material.
Published Light-weight microscope captures large-scale brain activity of mice on the move
(via sciencedaily.com) Original source With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments.
Published Moving objects precisely with sound
(via sciencedaily.com) Original source Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications such as noninvasive targeted drug delivery.
Published Novel application of optical tweezers: Colorfully showing molecular energy transfer
(via sciencedaily.com) Original source Using a novel non-contact approach, a research team has successfully controlled the speed and efficiency of Forster resonance energy transfer between fluorescent molecules by varying the intensity of a laser beam.
Published Controlling electronics with light: The magnetite breakthrough
(via sciencedaily.com) Original source Researchers have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g. making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics such as memory storage, sensors, and other devices that rely on fast and efficient material responses.
Published Researchers leverage shadows to model 3D scenes, including objects blocked from view
(via sciencedaily.com) Original source A new technique can model an entire 3D scene, including areas hidden from view, from just one camera image. The method relies on image shadows, which provide information about the geometry and location of hidden objects.
Published Researchers film energy materials as they form
(via sciencedaily.com) Original source Shooting a movie in the lab requires special equipment. Especially when the actors are molecules -- invisible to the naked eye -- reacting with each other. 'Imagine trying to film tiny lava flows during a volcanic eruption. Your smartphone camera wouldn't be up to the job.
Published Towards wider 5G network coverage: Novel wirelessly powered relay transceiver
(via sciencedaily.com) Original source A novel 256-element wirelessly powered transceiver array for non-line-of-sight 5G communication, featuring efficient wireless power transmission and high-power conversion efficiency, has been designed. The innovative design can enhance the 5G network coverage even to places with link blockage, improving flexibility and coverage area, and potentially making high-speed, low-latency communication more accessible.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light
(via sciencedaily.com) Original source Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light.

Published When bacteria are buckling
(via sciencedaily.com) Original source Filamentous cyanobacteria buckle at a certain length when they encounter an obstacle. The results provide an important basis for the use of cyanobacteria in modern biotechnology.
Published Reduction of esters by a novel photocatalyst
(via sciencedaily.com) Original source A ubiquitous compound, called ester can be broken down to produce desirable alcohols and other chemicals for use across industries including pharmaceuticals and cosmetics, but the process can be costly, both financially and in terms of the environment. Researchers developed a novel photocatalyst 'N-BAP.' When irradiated with blue light, the photocatalyst reduces esters in the presence of oxalate, a negatively charged molecule found widely in nature, resulting in the desired alcohols.
Published Quantum entanglement measures Earth rotation
(via sciencedaily.com) Original source Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
