Challenging the paradigms established by S. Dey et al. – Community of European Solar Radio Astronomers

Polarization measurements of solar radio emissions are key diagnostics of coronal plasma, magnetic fields, and propagation effects, and can provide additional constraints on emission mechanisms. At meter wavelengths, circular polarization (CP) has long been exploited in solar radio studies, while linear polarization (LP) was assumed to be absent. This view arose from the expectation that…

One of the most complete human ancestors ever found is not who we thought he was

In 1998, researchers discovered one of the most complete human ancestral fossils known in South Africa’s Sterkfontein Caves. Nearly two decades later, Ronald Clarke, the paleoanthropologist who led the excavation and analysis, identified the remains as a Australopithecus prometheuswhile others argued that it was a African Australopithecus. New research suggests it’s neither. In investigation Published…

Will melting glaciers cause increased seismic activity in mountainous regions? – State of the Planet

A recent study of Letters on Earth and Planetary Sciences is the first to directly link earthquakes to climate change-induced glacier melt. Scientists analyzed 15 years of seismic activity on the Grandes Jorasses, a peak that is part of the Mont Blanc massif between Italy and France, to better understand this association. This massif is…
