Researcher develops new methods to measure "forever chemicals" in both the atmosphere and in aerosol particles
From regulators to researchers and most industries in between, all eyes are on PFAS. PFAS, per-and polyfluoroalkyl substances, are a class of highly fluorinated human-made compounds that have been used for decades in everything from nonstick cookware.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Evolved in the lab, found in nature: Uncovering hidden pH sensing abilities in microbial cultures
In a study led by Sarah Worthan, Ph.D., a postdoctoral researcher in the Behringer Lab at Vanderbilt University, scientists have successfully evolved microbial cultures that possess the ability to sense pH changes, enabling rapid responses to environ.....»»
Team develops gene editing strategy for macroalgae Neopyropia
Neopyropia is an important economic macroalga and is one of the main macroalgae cultivation species in China, Japan, South Korea and other countries. As a critical juncture in the evolution of photosynthetic organisms, red algae to which Neopyropia b.....»»
Forever chemicals persist through waste incineration, researcher finds
PFAS, often called "forever chemicals," present in municipal solid waste can survive the high temperatures of waste incineration and continue to spread into the environment via residues from waste-to-energy plants......»»
Sea surface micro layer: Researchers study boundary between the ocean and the air
The boundary between the ocean and the atmosphere, where the air and sea interact, is known as the sea surface microlayer. Understanding how nutrients, pollutants and organic matter are exchanged between the air and the sea is also vital for better u.....»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
Were Bohr and von Neumann really in conflict over quantum measurements?
Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them......»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»
Harnessing nature"s rhythm: Piezocatalysis for organic pollutant degradation
With the rapid growth of industrial and agricultural activities, water bodies are increasingly contaminated with harmful organic pollutants such as dyes, antibiotics, and bisphenol A. Traditional methods like adsorption, chemical treatments, and biol.....»»
Rugged Falklands landscape was once a lush rainforest, researchers say
A researcher from the University of Southampton (UK) has found evidence that the treeless, rugged, grassland landscape of the Falkland Islands was home to a lush, diverse rainforest up to 30 million years ago......»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
Measuring moon dust to fight air pollution
Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to astronauts and valuable space.....»»
Project 2025 Would Drastically Cut Support for Carbon Removal
The Heritage Foundation’s plan for a potential Trump second term has little time for schemes to suck carbon dioxide out of the atmosphere......»»
Researcher discusses how finger counting may help improve math skills in kindergarten
Preschool teachers have different views on finger counting. Some teachers consider finger counting use in children to signal that they are struggling with math, while others associate its use as advanced numerical knowledge. In a new Child Developmen.....»»
Polaris Dawn crew member describes the dramatic ride home
A member of SpaceX’s Polaris Dawn mission has described what it was like aboard the Crew Dragon as it entered Earth’s atmosphere at high speed last weekend......»»
Surface water sampling reveals large numbers of juvenile krill undetected by conventional monitoring methods
In 2018–2019, researchers of Wageningen Marine Research joined the Japanese research vessel Kaiyo-maru (Fisheries Agency Japan; FAJ) on an Antarctic expedition to sample the upper surface waters with the Surface and Under Ice Trawl. Results showed.....»»
Nuclear theorists turn to supercomputers to map out matter"s building blocks in 3D
Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom's nucleus—particles called hadrons that a high school student would recognize as protons and neutrons—are made.....»»
Denver"s experiment in providing a soft landing for newly arrived migrants is expensive but necessary, says researcher
The burden of supporting asylum-seekers with food and housing often falls to cities, creating severe budget crunches. But Denver is piloting a new approach designed to integrate immigrants into the workforce faster......»»
Tiny robots and AI algorithms could help to craft material solutions for cleaner environments
Many human activities release pollutants into the air, water and soil. These harmful chemicals threaten the health of both people and the ecosystem. According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annu.....»»
