Answer to opal mystery shows Red Centre's links to Red Planet
(Phys.org) —The dramatic geological events that created opal, Australia's national gemstone, have been described for the first time by a University of Sydney researcher.
Seeding oceans with iron may not confer promised climate benefits
Adding iron to the Southern Ocean may not have the climate benefits that advocates of geoengineering have hoped for, a new study suggests.
Unique chemistry in hydrogen catalysts
Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University ...
Nanoparticles infiltrate, kill cancer cells from within
Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect (and potentially harm) nearby normal cells.
Iron in the sun: A greenhouse gas for X-ray radiation
(Phys.org) —Scientists from the Heidelberg Max Planck Institute for Nuclear Physics (MPIK) in cooperation with DESY (Hamburg) at the synchrotron PETRA III have investigated for the first time X-ray absorption ...
Iron in the Earth's core weakens before melting
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to ...
Nanoscale details of electrochemical reactions in electric vehicle battery materials
Using a new method to track the electrochemical reactions in a common electric vehicle battery material under operating conditions, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have revealed ...
Probing hydrogen catalyst assembly
Biochemical reactions sometimes have to handle dangerous things in a safe way. New work from researchers at UC Davis and Stanford University shows how cyanide and carbon monoxide are safely bound to an iron atom to construct ...
Findings may advance iron-rich, cadmium-free crops
With news reports of toxic cadmium-tainted rice in China, a new study describes a protein that transports metals in Arabidopsis plants and holds promise for developing iron-rich but cadmium-free crops.
Optimizing electronic correlations for superconductivity
(Phys.org) —The decadeslong effort to create practical superconductors moved a step forward with the discovery at Rice University that two distinctly different iron-based compounds share common mechanisms for moving electrons.
Newly discovered ocean plume could be major source of iron
(Phys.org) —Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding, soon to be published ...
Collecting light with artificial moth eyes
All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a ...
Graphene nanoscrolls are formed by decoration of magnetic nanoparticles
Researchers at Umea University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls ...
Ancient Egyptians accessorized with meteorites
Researchers at The Open University (OU) and The University of Manchester have found conclusive proof that Ancient Egyptians used meteorites to make symbolic accessories.
