Published Global cooling caused diversity of species in orchids, confirms study
(via sciencedaily.com)
Original source 
Research shows global cooling of the climate 10 million years ago led to an explosion of diversity in terrestrial orchids.
Published Number cruncher calculates whether whales are acting weirdly
(via sciencedaily.com)
Original source 
We humans can be a scary acquaintance for whales in the wild. This includes marine biologists tagging them with measuring devices to understand them better. These experiences can make whales behave erratically for a while. Such behaviour can affect research quality and highlights an animal ethics dilemma. Now, researchers have figured out how to solve the problems with math.
Published Why the day is 24 hours long: Astrophysicists reveal why Earth's day was a constant 19.5 hours for over a billion years
(via sciencedaily.com)
Original source 
Astrophysicists have revealed how the slow and steady lengthening of Earth's day caused by the tidal pull of the moon was halted for over a billion years. They show that from approximately two billion years ago until 600 million years ago, an atmospheric tide driven by the sun countered the effect of the moon, keeping Earth's rotational rate steady and the length of day at a constant 19.5 hours. Without this billion-year pause in the slowing of our planet's rotation, our current 24-hour day would stretch to over 60 hours. The paper offers a new perspective on how global warming will affect the length of our day and validates global circulation models as a climate modelling tool.
Published Earth's Inner Core: Earth's solid metal sphere is 'textured'
(via sciencedaily.com)
Original source 
Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 years by a network of seismometers set up to enforce the nuclear test ban treaty.
Published Water storage capacity in oceanic crust slabs increases with age, researchers find
(via sciencedaily.com)
Original source 
An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction zone, the bigger the water storage capacity.
Published Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes
(via sciencedaily.com)
Original source 
Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.
Published Climate change will increase impacts of volcanic eruptions
(via sciencedaily.com)
Original source 
Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.
Published Geologists are using artificial intelligence to predict landslides
(via sciencedaily.com)
Original source 
Many factors influence where a landslide will occur, including the shape of the terrain, its slope and drainage areas, the material properties of soil and bedrock, and environmental conditions like climate, rainfall, hydrology and ground motion resulting from earthquakes. Geologists have developed a new technique that uses artificial intelligence to better predict where and why landslides may occur could bolster efforts to protect lives and property in some of the world's most disaster-prone areas. The new method improves the accuracy and interpretability of AI-based machine-learning techniques, requires far less computing power and is more broadly applicable than traditional predictive models.
Published Researchers unearth the mysteries of how Turkey's East Anatolian fault formed
(via sciencedaily.com)
Original source 
An international team has, for the first time, accurately determined the age of the East Anatolian fault, allowing geologists to learn more about its seismic history and tendency to produce earthquakes.
Published What are the characteristics of foreshocks for large earthquakes?
(via sciencedaily.com)
Original source 
Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks?
Published Research in a place where geological processes happen before your eyes
(via sciencedaily.com)
Original source 
Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.
Published Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide
(via sciencedaily.com)
Original source 
Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
Published Generative AI models are encoding biases and negative stereotypes in their users
(via sciencedaily.com)
Original source 
In the space of a few months generative AI models, such as ChatGPT, Google's Bard and Midjourney, have been adopted by more and more people in a variety of professional and personal ways. But growing research is underlining that they are encoding biases and negative stereotypes in their users, as well as mass generating and spreading seemingly accurate but nonsensical information. Worryingly, marginalized groups are disproportionately affected by the fabrication of this nonsensical information.
Published Sinking seamount offers clues to slow motion earthquakes
(via sciencedaily.com)
Original source 
The first ever 3D seismic imaging of a subducting seamount shows a previously unknown sediment trail in Earth's crust off the coast of New Zealand. Scientists think the sediment patches help release tectonic pressure gradually in slow slip earthquakes instead of violent tremors. The findings will help researchers search for similar patterns at other subduction zones like Cascadia in the U.S. Pacific Northwest.
Published Vastly more sustainable, cost-effective method to desalinate industrial wastewater
(via sciencedaily.com)
Original source 
Engineers are developing a cutting-edge process that can reduce energy consumption and cost of water desalination.
Published Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate
(via sciencedaily.com)
Original source 
A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and persisting today.
Published A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com)
Original source 
New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
Published Bridging traditional economics and econophysics
(via sciencedaily.com)
Original source 
How do asset markets work? Which stocks behave similarly? Economists, physicists, and mathematicians work intensively to draw a picture but need to learn what is happening outside their discipline. A new paper now builds a bridge.
Published We've pumped so much groundwater that we've nudged Earth's spin
(via sciencedaily.com)
Original source 
By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study.
Published Massive underwater plateau near Solomon Islands is younger and its eruption was more protracted than previously thought
(via sciencedaily.com)
Original source 
The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, new research suggests.
