Preserving forests to protect deep soil from warming      (via sciencedaily.com)     Original source 

An innovative, decade-long experiment in the foothills of California's Sierra Nevada mountains shows carbon stocks buried deep underground are vulnerable to climate change. The findings have implications for mitigating global warming through the natural carbon sinks provided by soil and forests which capture 25% of all carbon emissions.

A machine learning approach to freshwater analysis      (via sciencedaily.com)     Original source 

A team of researchers has applied a machine learning model to explore where and to what extent human activities are contributing to the hydrogeochemical changes, such as increases in salinity and alkalinity in U.S. rivers. The group used data from 226 river monitoring sites across the U.S. and built two machine learning models to predict monthly salinity and alkalinity levels at each site.

Marine environment at risk due to ship emissions      (via sciencedaily.com)     Original source 

Researchers used four different types of port environments to investigate the levels of contaminants emitted from five different sources. They found that the combined emissions of metals and environmentally hazardous substances is putting the marine environment at risk. Ninety per cent of the harmful emissions came from ships fitted with scrubbers, whose purpose is to clean their exhaust gases.

Researchers describe the melting of gold nanoparticles in gold-bearing fluids in the Earth's crust      (via sciencedaily.com)     Original source 

Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold --regarded as the noblest of metals-- has been a symbol of splendour and wealth in many civilizations. Historically, gold deposits were known to form when metal was transported dissolved by hot aqueous solution flows --hydrothermal fluids-- until it accumulated in some areas in the Earth's upper crust. The recent discovery of gold nanoparticles in such mineral deposits has brought some doubts on the validity of the classical model.

Chronic exposure to lead, cadmium and arsenic increases risk of cardiovascular disease      (via sciencedaily.com)     Original source 

Around the world, most people are regularly exposed to low or moderate levels of lead, cadmium and arsenic in the environment, increasing risk of coronary artery disease, stroke and peripheral artery disease, according to a new statement.

New model offers a way to speed up drug discovery      (via sciencedaily.com)     Original source 

A model known as ConPLex can predict whether potential drug molecules will interact with specific protein targets, without having to perform the computationally intensive calculation of the molecules' structures. By applying a language model to protein-drug interactions, researchers can quickly screen large libraries of potential drug compounds.

Eddies: Circular currents and their influence on the world's hottest ocean      (via sciencedaily.com)     Original source 

Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the Indian Ocean.

Why certain fish are left off the hook      (via sciencedaily.com)     Original source 

A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.

Sustainable technique to manufacture chemicals      (via sciencedaily.com)     Original source 

A newly published study details a novel mechanochemistry method that can produce chemicals using less energy and without the use of solvents that produce toxic waste.

When water temperatures change, the molecular motors of cephalopods do too      (via sciencedaily.com)     Original source 

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.

A new way to develop drugs without side effects      (via sciencedaily.com)     Original source 

Have you ever wondered how drugs reach their targets and achieve their function within our bodies? If a drug molecule or a ligand is a message, an inbox is typically a receptor in the cell membrane. One such receptor involved in relaying molecular signals is a G protein-coupled receptor (GPCR). About one-third of existing drugs work by controlling the activation of this protein. Researchers now reveal a new way of activating GPCR by triggering shape changes in the intracellular region of the receptor. This new process can help researchers design drugs with fewer or no side effects.

Schrödinger's cat makes better qubits      (via sciencedaily.com)     Original source 

Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.

Physicists discover an exotic material made of bosons      (via sciencedaily.com)     Original source 

Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.

Calculation shows why heavy quarks get caught up in the flow      (via sciencedaily.com)     Original source 

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.

Measuring greenhouse gas from ponds improves climate predictions      (via sciencedaily.com)     Original source 

Shallow lakes and ponds emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems vary considerably and are not well understood.

The problems with coal ash start smaller than anyone thought      (via sciencedaily.com)     Original source 

Burning coal doesn't only pollute the air. The resulting ash can leach toxic chemicals into the local environments where it's kept. New research shows that the toxicity of various ash stockpiles relies heavily on its nanoscale structures, which vary widely between sources. The results will help researchers predict which coal ash is most environmentally dangerous.
