Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are quantized, meaning they come in tiny packets called photons and electrons. In a solar cell, the energy of a single photon is transferred to a single electron of the material, but no more than one. Only a...
Microbiologists have uncovered the evolutionary origins of antimicrobial resistance (AMR) in bacteria. His studies on the bacterium that causes cholera, Vibrio cholerae, provide insight into deciphering what conditions must occur for infectious agents to become resistant. He studied genetic variants of a protein found in bacterial membranes called OmpU. Using computational and molecular...
Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Because contrasting societal views have created an approach that simultaneously manages horses on the range as wildlife, livestock and pets, current U.S. government programs are incapable of succeeding, according to researchers.
Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain involved in learning, memory and sensory integration) of 'primitive' sawflies and sophisticated honey bees. They found that three diverse, specialized...
Researchers have captured one of the fastest movements of a molecule called ferricyanide for the first time by combining two ultrafast X-ray spectroscopy techniques. They think their approach could help map more complex chemical reactions like oxygen transportation in blood cells or hydrogen production using artificial photosynthesis.
Providing defendants with legal counsel during their initial bail hearing decreases use of monetary bail and pretrial detention, without increasing the likelihood that defendants fail to appear at the subsequent preliminary hearing, according to a new RAND Corporation study.

Brownfield restoration has become a frontier topic in the research on urban ecosystem governance. Optimizing brownfield ecosystems through proper bioremediation approaches can provide urban landscapes and habitats with sound ecological potentials. Currently, the lagging theory and technique development of brownfield vegetation restoration, the species selection based on single causality, and the...
A scientist will attempt to turn seismic activity—recorded in real time at Yellowstone National Park—into music during an ambitious live performance on Tuesday, May 9.
The Middle East and North African region lose about $13 billion a year because of increasing sand and dust storms. By combining learnings from artificial intelligence and 3000-year-old sustainable methods, researchers might be on the way to finding out how to mitigate the damages.
Poorly monitored badger farming and illegal poaching in South Korea is a cause for concern for wildlife and human health, with regulation of the trade urgently needed, according to a new study involving UCL researchers.
Bacteria naturally adapt to various environmental stimuli and as they mutate, these changes can make them resistant to drugs that would kill or slow their growth.
As humans contemplate life on other planets, we are immediately confronted with two choices. One is a journey to another solar system that would take tens of thousands of years (with current technology), requiring around 2,000 generations to live out their existence in the cramped confines of a spacecraft while adhering to a strict population control scheme. The other choice is Mars.
Led by Jizhong Zhou, Ph.D., the director of the Institute for Environmental Genomics at the University of Oklahoma, an international research team conducted a long term experiment that found that climate warming reduced the diversity of and significantly altered the community structure of soil archaea. Their findings are published in the journal Nature Climate Change.
“Cool as a cucumber” might be better phrased as “cool as a mushroom.” A research team has found that mushrooms and other fungi, including yeast and molds, stay cooler than their surroundings—and has also explained how they stay so chill. The contain a lot of water—just think how mushrooms shrink when cooked—and gradually release it in a fungal form of sweating that...
In August 2020, Federal Reserve Chair Jerome Powell announced a change in the Fed's inflation strategy: they would be implementing a strategy called average inflation targeting (AIT), which allows inflation to move above and below the target rate of 2% so that it averages out to 2% over time. This differs from the previous strategy of traditional inflation targeting, in which the intent is to...

Alfalfa (Medicago sativa), commonly called the "King of Grass," is a legume grown in many parts of the world as a source of animal fodder. It is prized in the forage industry for its high protein content and biomass yield. Recently, alfalfa protein has found applications in aquaculture, pet food industry and human diet. Furthermore, it is seen as an environmentally beneficial crop, with positive...
The Okinawa Trough is a newly formed back-arc basin located in the outer margin of the continental shelf of the East China Sea. The submarine hydrothermal activities are widely developed in the Okinawa Trough. A typical feature of the basin is that the hydrothermal fluids are highly rich in CO2.
When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities and their value for the development of highly performing lasers or other technologies.
Old-growth forests are of exceptional importance for biodiversity and climate protection in Europe, but they are increasingly rare. Despite the European Union's (EU) pledge in its Biodiversity Strategy for 2030, legislation to protect old-growth remnants still has not been implemented in many member states. Old-growth forest loss continues at alarming rates.
