Identifying organic compounds with visible light
Researchers from the Universidad de Santiago de Chile and the University of Notre Dame, working with machine learning, have devised a method to identify organic compounds based on the refractive index at a single optical wavelength. The technique cou.....»»
Research team resolves decades-long problem in microscopy
When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by air, the light rays bend more.....»»

Monash University ornithologists have shed light on the intricate relationship between social structure, environmental conditions, and cooperative behavior in superb fairy-wrens (Malurus cyaneus)......»»
Sink to source: Does what we put into our plumbing end up back in the water supply?
When you see an advertisement for a detergent promising to brighten your clothes, something called a fluorescent whitening compound, or optical brightener, is probably involved. Such material absorbs UV light and emits visible blue light via fluoresc.....»»
Plant sensors could act as an early warning system for farmers
Using a pair of sensors made from carbon nanotubes, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have discovered signals that reveal when plans are experiencing stresses such as heat, light, or attack from i.....»»

Visible is already one of the more affordable choices for unlimited 5G. Now, new plans are making Visible an even better deal than ever......»»
Silver-based micromotors that eliminate bacteria can move freely in aqueous media
Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity......»»
Second-biggest black hole in the Milky Way found
May help explain why we see so many of these monsters colliding. Enlarge / The star's orbit, shown here in light, is influenced by the far more massive black hole, indicated by the red orbit. (credit: ESO/L. Calçada) As.....»»
Physical field technologies to improve extraction and quality of extracted juices
Consumers are increasingly health-conscious and seek products with minimal additives and preservatives. The modern consumer understands the link between consuming bioactive compounds from fruits and vegetables and the associated health benefits. Henc.....»»
Cut light pollution and treat glass to help migrating birds, say researchers
Spring bird migration has begun. Under cover of darkness, 2.5–3.5 billion birds will fly northward to their breeding grounds in the United States and Canada. According to the Cornell Lab of Ornithology, now is one of the most important times of yea.....»»
Pioneering crop productivity and sustainability in the face of water scarcity
A research team has shed light on the early morning "golden hours" as a pivotal time for achieving optimal water use efficiency (WUE) in crops, revealing that plants can maintain lower transpiration rates and higher photosynthetic activity under favo.....»»
