Micelles assemble in water from amphiphilic molecules, composed of hydrophilic and hydrophobic frameworks. They can be found all around us, for example in soaps, detergents, and shampoos. Their main application is the water-solubilization of insoluble molecules through encapsulation into hydrophobic cavities.

An electrochemical process developed at Georgia Tech could offer new protection against bacterial infections without contributing to growing antibiotic resistance.

As humanity grapples with the fight against climate change, reducing greenhouse gas emissions is urgently necessary. One way to achieve this is through the carbon offset market, where organizations or individuals can buy credits from emissions-reducing projects.

A paper, titled "Global Mercury Concentrations in Biota: Their Use as a Basis for a Global Biomonitoring Framework" and published in the journal Ecotoxicology, describes for the first time currently available mercury data for fish and wildlife on a global scale. Data from the peer-reviewed literature, compiled in the Global Biotic Mercury Synthesis (GBMS) database of the Biodiversity Research Institute (BRI), will help inform worldwide efforts to reduce the impact of mercury pollution on people and the environment.

Chicken breast jerky (CBJ) is a popular pet food due to its high crude protein content and long shelf life. In the production of CBJ, the drying process is a crucial step. However, the physicochemical and functional properties of CBJ depend on the drying method used.

Like most countries, China has had its problems with air pollution. However, over the last decade, a series of successful measures implemented by the Chinese government have resulted in an impressive improvement in air quality.

Melon aroma greatly influences consumer preference and fruit quality. Climacteric melons produce more esters, while non-climacteric melons have more aldehydes. Understanding these genetic differences is crucial for breeding better melons. Although genes involved in volatile organic compound (VOC) biosynthesis have been identified, a comprehensive genetic map is still missing. In-depth research is needed to uncover the genetic basis of melon aroma and ripening behavior.

A research team has meticulously analyzed the transcriptional response of Impatiens walleriana to Plasmopara obducens infection, revealing between 3,000 and 4,500 differentially expressed transcripts at various stages of the disease.

A research team has developed a novel conceptual framework for designing plastic-greenhouse soil profiles that cater to the needs of smallholder farmers. The soil profile includes four functional layers: a soil mulch layer for preventing evaporation, a root-carbon layer for nutrient, CO2, and heat generation, a soil-carbon mix layer for buffering and nutrient supply, and a water conservation layer to store water and nutrients.

Researchers analyzed water quantity and quality data from domestic agricultural reservoirs to shed light on the hydrological impacts of a severe drought on degrading the water quality.

Drinking tea can have several health benefits. There is seemingly a brew for everything from sleep to inflammation to digestion. In 18th century England, however, drinking tea may have saved a person's life, and it likely had very little to do with leaves and herbs.

As part of NASA's efforts to expand commercial resupply in low Earth orbit, Sierra Space's uncrewed spaceplane arrived at NASA's Kennedy Space Center in Florida ahead of its first flight to the International Space Station.

Dozens of Alaska's most remote streams and rivers are turning from a crystal clear blue into a cloudy orange, and the staining could be the result of minerals exposed by thawing permafrost, finds new research in Communications Earth & Environment.

A team led by Professor Jongmin Choi of the Department of Energy Science and Engineering has developed a PbS quantum dot that can rapidly enhance the electrical conductivity of solar cells. The findings are published in the journal Small.

Researchers have developed a new theory of how changing market conditions can lead large numbers of otherwise cautious consumers to buy risky products such as subprime mortgages, cryptocurrency or even cosmetic surgery procedures.

Post-doctoral researcher Joe Edwards and graduate student Sarah Love, both in the University of Tennessee at Knoxville's Department of Ecology and Evolutionary Biology, have published published findings this spring that can save fellow researchers a lot of time and energy when storing soil samples for later study of their microbial content.

From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces is a heavily researched subject, where new discoveries can have profound effects in the fields of energy conversion technology, electronics cooling, biosensors, and micro-/nano-fabrications.

Spectroscopy is the study of how matter absorbs and emits light and other radiation. It allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. Classical optical spectroscopy relies on the way particles of light called photons interact with matter. These classical spectroscopy techniques include one-photon absorption (OPA) and two-photon absorption (TPA).

Seeing is believing. But according to new virtual reality research from the University of Oregon, observation may not be enough to activate people on environmental issues. Engagement is key.

Scientists have identified a new member on the genetic family tree of an endangered pupfish native to south-central New Mexico.

Deposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most implicated in climate change.

A study has tapped into the peach genome, creating large-scale gene co-expression networks (GCNs) that predict gene functions and streamline the peach breeding process. This innovative approach addresses the complex task of identifying genes linked to desirable breeding traits in peaches.

Scientists have developed DIProT, an innovative, user-friendly toolkit for protein design. The toolkit utilizes a non-autoregressive deep generative model to address the protein inverse folding problem, integrating human expertise into the design loop for efficient and effective protein design.

Endangered species are often characterized by severe population decline or even near-extinction status during their demographic histories. Such threats usually stem from historical climate changes and human activities.

For hundreds of years, the whitespotted eagle ray (Aetobatus narinari) has been considered the only inshore stingray species in Bermuda, until now.
