Using a volcano's eruption 'memory' to forecast dangerous follow-on explosions
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as 'Strombolian paroxysms'. During such events several of Stromboli's craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano. (2020-10-28)

How do basal ganglia neurons convey information for the control of voluntary movements?
Researchers revealed how neurons in the basal ganglia, which are a brain region crucial for the control of voluntary movements and whose damage induces motor impairment, such as Parkinson's disease, convey information for the movement control by recording activity of multiple neurons simultaneously in Japanese monkeys.

How a greenhouse catastrophe killed nearly all life
252 million years ago at the boundary between the Permian and Triassic epochs, Earth witnessed a mass extinction event that extinguished about three-quarters of all species on land and some 95 percent of all species in the ocean. Volcanic activity in today's Siberia has long been debated as a likely trigger of this event. Now, an international team of researchers provides for the first time a conclusive reconstruction of the key events that led to the mega-catastrophe. (2020-10-19)

Deep learning artificial intelligence keeps an eye on volcano movements
RADAR satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, Penn State researchers have used artificial intelligence (AI) to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest.

Reading in company boosts creativity
Language has evolved as a consequence of social interaction; however, most research is conducted with participants in isolation. What happens in our brain when we read in the company of others? Is it the same as reading alone? Researchers at the Complutense University of Madrid and the Carlos III Health Institute have found that company is conducive to a more creative and integrated understanding of language, whereas isolation favours more systematic and automatic language processing.

Living in an anoxic world: Microbes using arsenic are a link to early life
Much of life on planet Earth today relies on oxygen to exist, but before oxygen was present on our blue planet, lifeforms likely used arsenic instead. These findings are detailed in research published today in Communications Earth and Environment. (2020-09-22)

Indian monsoon can be predicted better after volcanic eruptions
Large volcanic eruptions can help to forecast the monsoon over India - the seasonal rainfall that is key for the country's agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El Niño phenomenon after an eruption. (2020-09-18)

Sea ice triggered the Little Ice Age, finds a new study
A new study finds a trigger for the Little Ice Age that cooled Europe from the 1300s through mid-1800s, and supports surprising model results suggesting that under the right conditions sudden climate changes can occur spontaneously, without external forcing. (2020-09-17)

Venus' ancient layered, folded rocks point to volcanic origin

Discovery of a new mass extinction
It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode. (2020-09-16)

Phosphine on Venus
An international team of astronomers detected phosphine (PH3) in the atmosphere of Venus. They studied the origin of phosphine, but no inorganic processes, including supply from volcanos and atmospheric photochemistry can explain the detected amount of phosphine. The phosphine is believed to originate from unknown photochemistry or geochemistry, but the team does not completely reject the possibility of biological origin. This discovery is crucial to examine the validity of phosphine as a biomarker. (2020-09-15)

When methane-eating microbes eat ammonia instead
As a side effect of their metabolism, microorganisms living on methane can also convert ammonia. In the process, they produce nitric oxide (NO), a central molecule in the global nitrogen cycle. Scientists from the Max Planck Institute for Marine Microbiology, Bremen (DE), and Radboud University, Nijmegen (NL), now discovered the enzyme that produces NO, closing an important gap in our understanding of how methanotrophs deal with rising environmental ammonia concentrations. (2020-09-13)
