Natural diamonds can form through low pressure and temperature geological processes on Earth, as stated in an article published in the journal Geochemical Perspectives Letters.
An international simulation study by scientists from the US, Australia, and Germany, shows that alternative explanatory models such as asteroid impacts do not generate sufficiently large magnetic fields.
In drought prone Australia, it's largest river, the Murray is known to suffer acidification in its estuary in South Australia. For the first time a study has married geomorphology and environmental chemistry to gain a better understanding of how the lakes formed - and how they should be managed.
Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
Scientists at The University of Tokyo used computer simulations and a two-state mathematical model to analyze previous data on water and predicted the location of a liquid-liquid critical point in supercooled water. This work may help better understand the unusual properties of water that allow life to exist in its current form on Earth.
Using radio telescopes observing distant stars, scientists have connected optical atomic clocks on different continents. The results were published in the scientific journal Nature Physics by an international collaboration between 33 astronomers and clock experts at the National Institute of Information and Communications Technology (NICT, Japan), the Istituto Nazionale di Ricerca Metrologica (INRIM, Italy), the Istituto Nazionale di Astrofisica (INAF, Italy), and the Bureau International des Poids et Mesures (BIPM, France).
The current climate crisis underlines that carbon cycle perturbations can cause significant climate change. New research reveals how carbon cycle and global climate have been interacting throughout the last 35 million years of geologic history, under natural circumstances. The study, led by David De Vleeschouwer from MARUM - Center for Marine Environmental Sciences at the University of Bremen, was now published in Nature Communications.
Fourteen laboratories participated in this interlaboratory comparison exercise (ILC). The results indicated good analytical performance by the participating laboratories, but the results of the 210Pb dating did not reach the desired level of satisfaction.
Allowing for quantum corrections, the Einstein-Lovelock theory describes black holes with an equation that contains an infinite number of terms. However, according to a RUDN University physicist, the geometry of a black hole in this theory can be presented in a compact form, and a limited number of terms can suffice to describe the observed values. This could help scientists study black holes in theories with quantum corrections to Einstein's equations.
Naturally formed balancing boulders could be used to help scientists to forecast large earthquakes more precisely.
