Feedback loop that is melting ice shelves in West Antarctica revealed      (via sciencedaily.com)     Original source 

New research has uncovered a feedback loop that may be accelerating the melting of the floating portions of the West Antarctic Ice Sheet, pushing up global sea levels. The study sheds new light on the mechanisms driving the melting of ice shelves beneath the surface of the ocean, which have been unclear until now.

Predicting cardiac arrhythmia 30 minutes before it happens      (via sciencedaily.com)     Original source 

Atrial fibrillation is the most common cardiac arrhythmia worldwide with around 59 million people concerned in 2019. This irregular heartbeat is associated with increased risks of heart failure, dementia and stroke. It constitutes a significant burden to healthcare systems, making its early detection and treatment a major goal. Researchers have recently developed a deep-learning model capable of predicting the transition from a normal cardiac rhythm to atrial fibrillation. It gives early warnings on average 30 minutes before onset, with an accuracy of around 80%. These results pave the way for integration into wearable technologies, allowing early interventions and better patient outcomes.

Surf clams off the coast of Virginia reappear -- and rebound      (via sciencedaily.com)     Original source 

The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a comprehensive study of surfclams collected from an area about 45 miles due east from the mouth of the Chesapeake Bay, scientists found the population to be thriving and growing.

The Italian central Apennines as a source of CO2      (via sciencedaily.com)     Original source 

Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of rock. At depth, the heating and melting of carbonate rock leads to the outgassing of CO2 at the surface. In the central Italian Apennine Mountains, researchers have now investigated and balanced all of these processes in one region for the first time -- using, among others, analyses of the CO2 content in mountain rivers and springs.

Weather prediction models can also forecast satellite displacements      (via sciencedaily.com)     Original source 

Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds.

When thoughts flow in one direction      (via sciencedaily.com)     Original source 

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks.

East coast mussel shells are becoming more porous in warming waters      (via sciencedaily.com)     Original source 

Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.

Florida Wildlife Corridor eases worst impacts of climate change      (via sciencedaily.com)     Original source 

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.

Hidden threat: Global underground infrastructure vulnerable to sea-level rise      (via sciencedaily.com)     Original source 

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.
