Formation of a huge underwater volcano offshore the Comoros
A new submarine volcano was formed off the island of Mayotte in the Indian Ocean in 2018. This was shown by an oceanographic campaign...
Laser pulse creates frequency doubling in amorphous dielectric material
Researchers have demonstrated a new all-optical technique for creating robust second-order nonlinear effects in materials that don't normally support them. Using a laser pulse...
Biodiverse forests better at storing carbon for long periods, says study
As the effects of climate change are increasingly felt around the world, possible solutions—from reducing fossil fuel emissions to capturing carbon—have come to dominate...
The turbulent life of two supermassive black holes caught in a galaxy crash
An international team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to create the most detailed image yet of the gas surrounding two...
New evidence shows that the key assumption made in the discovery of dark energy...
The most direct and strongest evidence for the accelerating universe with dark energy is provided by the distance measurements using type Ia supernovae (SN...
Clusters of gold atoms form peculiar pyramidal shape
Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered. This is in contrast with most elements, which organize...
Over-hunting walruses contributed to the collapse of Norse Greenland, study suggests
The mysterious disappearance of Greenland's Norse colonies sometime in the 15th century may have been down to the overexploitation of walrus populations for their...
Astronomers find wandering massive black holes in dwarf galaxies
Astronomers seeking to learn about the mechanisms that formed massive black holes in the early history of the Universe have gained important new clues...
Superconductor or not? Exploring the identity crisis of this weird quantum material
Northeastern researchers have used a powerful computer model to probe a puzzling class of copper-based materials that can be turned into superconductors. Their findings...
Sustainable supply of minerals and metals key to a low-carbon energy future
The global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply...
Scientists pin down timing of lunar dynamo’s demise
A conventional compass would be of little use on the moon, which today lacks a global magnetic field.
But the moon did produce a magnetic...
