New discovery may allow scientists to make fuel from CO2 in the atmosphere
(Phys.org) —Excess carbon dioxide in the Earth's atmosphere created by the widespread burning of fossil fuels is the major driving force of global climate change, and researchers the world over are looking ...
Jekyll and Hyde corals tell different warming story
(Phys.org) —Like the rings of a tree trunk, Strontium-to-calcium ratios (Sr/Ca) in coral skeletons have been widely used to determine past ocean temperatures from yearly banded corals. However, scientists ...
Glass-blowers at nano scale: Researchers use STM to change size of glass capillary tubes
Have you ever thrown into the fire - even if you shouldn't have - an empty packet of crisps? The outcome is striking: the plastic shrivels and bends into itself, until it turns into a small crumpled and blackened ...
Laser empties atoms from the inside out
An international team of plasma physicists has used one of the world's most powerful lasers to create highly unusual plasma composed of hollow atoms.
Experiments demonstrate unusual melting and recrystallization behavior in one-dimensional electron crystals
(Phys.org) —The melting of ice is a familiar process: the ice gradually loses its crystalline structure and becomes a featureless puddle of liquid. Normally, no amount of further heating will bring back ...
Another link between CO2 and mass extinctions of species
(Phys.org) —It's has been know that massive increases in emission of CO2 from volcanoes, associated with the opening of the Atlantic Ocean in the end-Triassic Period, set off a shift in state of the climate ...
Four-wavelength integrated silicon laser for inter-processor data transmission
Fujitsu Laboratories announced the development of a four-wavelength integrated silicon laser for optical transceivers that use silicon photonics, a step toward faster data communications between processors.
Planck's most detailed map ever reveals an almost perfect Universe
(Phys.org) —Acquired by ESA's Planck space telescope, the most detailed map ever created of the cosmic microwave background – the relic radiation from the Big Bang – was released today revealing the ...
Materials scientists make solar energy chip 100 times more efficient
(Phys.org) —Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) have improved an innovative solar-energy device to be about 100 times more efficient than its previous ...
Global warming could cause goat populations to rocket
Practice makes perfect with Webb telescope mirror placement
(Phys.org) —NASA engineers and scientists have been making practice runs to ensure the placement of primary mirror segments on the James Webb Space Telescope go perfectly when the flight equipment is ready. ...
Alloy has potential for electronics in wells
An alloy that may improve high-temperature electronics in oil and geothermal wells was really a solution in search of a problem.
