Recreating the natural light-harvesting nanorings in photosynthetic bacteria
Nearly all the chemical energy available to Earth's lifeforms can be traced back to the sun. This is because light-harvesting (LH) supramolecules (two or more molecules held together by intermolecular forces) enable plants and some types of bacteria.....»»
Researchers develop organic photoredox catalysts with enhanced stability and recyclability
In recent years, global environmental concerns have prompted a shift toward eco-friendly manufacturing in the field of organic synthetic chemistry. In this regard, research into photoredox catalytic reactions, which use light to initiate redox or red.....»»
Why Are We Seeing These Crazy Northern Lights?
The aurora borealis is usually seen near the Arctic, but solar winds and magnetic turbulence are sparking some of the best light shows in centuries throughout the US......»»
Researchers describe spin-boson systems to configure quantum devices
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the "0" and the "1." However, spins in real devices also interact with light and vibrations known as bosons, greatly com.....»»
Hubble captures jewel-bright spiral galaxy NGC 4689
This NASA/ESA Hubble Space Telescope image shows the jewel-bright spiral galaxy NGC 4689, which lies 54 million light-years from Earth in the constellation Coma Berenices. This constellation has the distinction of being the only one of the 88 constel.....»»
BMW, Mercedes, Volvo turn to natural fibers to make cars more sustainable

First topological quantum simulator device in strong light-matter interaction regime to operate at room temperatures
Researchers at Rensselaer Polytechnic Institute have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings, published in the journal Nature Nanotechnology, coul.....»»
Study reveals key role of plant-bacteria communication for assembly of a healthy plant microbiome
In an interdisciplinary study, researchers have discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insight.....»»
Scientists report on a new approach for deducing proton radii from charge-changing reactions
A study systematically measured the charge-changing reaction cross section of 24 light nuclei on carbon and hydrogen targets at the GSI Helmholtz Centre for Heavy Ion Research in Germany......»»

A newly discovered exoplanet has almost the same temperatures as Earth
A Venus-sized exoplanet located just 40 light years away may be the smoking gun that astronomers have been looking for in their search for an … The post A newly discovered exoplanet has almost the same temperatures as Earth appeared first on BG.....»»
Earth 2.0 or its evil twin? Discovery of Earth-sized planet could shed light on conditions necessary for life
The discovery of a planet similar to Venus around a star in the neighborhood of the solar system raises hopes that astronomers may someday unlock the secret to why life appeared on Earth......»»
New insights into the interaction of femtosecond lasers with living tissue
Nonlinear light microscopy has revolutionized our ability to observe and understand complex biological processes. However, light can also damage living matter. Yet, the mechanism behind the irreversible perturbation of cellular processes by intense l.....»»
Researchers propose use of electrical blackouts to determine impact of artificial light on wildlife
New research proposes the use of electrical blackouts, such as those experienced during loadshedding in South Africa, to enhance our understanding of how artificial light in urban areas may be affecting wildlife behaviors......»»
New discoveries about the nature of light could improve methods for heating fusion plasma
Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plas.....»»
Shedding light on the chemical enigma of sulfur trioxide in the atmosphere
Researchers at Tampere University have discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids......»»
Quantum photonic technologies set to be more reliable with new interferometer
An increasing number of emerging quantum applications operate using optical technologies. Essentially, photons carry information at the speed of light and over long distances, making them good candidates for fast and secure communications and quantum.....»»
Potentially habitable "exo-Venus" with Earth-like temperature discovered
Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The new paper "Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS.....»»
Study sheds light on how antibiotic "Velcro" kills bacteria
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro form a bond......»»
A merger of microbes: Study shows low-nutrient conditions alter viral infection
This much we know: When viruses infect bacteria—a common occurrence in oceans, soils, even human guts—the interaction results in the creation of entirely new organisms called "virocells." But scientists are still learning about how this merger of.....»»
