A new study reveals that Greenland's ice sheet has experienced a significant increase in crevasses over the past five years, equivalent to adding a crack the size of the Great Pyramid of Giza every few days. The findings suggest a potential feedback loop that accelerates ice loss from the glacier, ultimately raising sea levels.
Researchers developed a neural network model to accelerate detection of brain rhythms, reducing feedback signal delay from 500ms to 10ms. The approach shows promise for treating attention deficit disorder and epilepsy.
A recent study by IIASA and Fudan University warns that relying too much on biomass-based carbon removal technologies could exacerbate global warming and reduce crop yields, leading to food shortages. The simulation results show that delayed mitigation and BECCS deployment could increase global warming from 1.7°C to 3.7°C by 2200.
A new study using tree-ring data found that inner East Asia experienced a unique and unprecedented rise in heatwave-drought events over the last two decades. The findings suggest a positive feedback loop between declining soil moisture and increasing surface warming, potentially leading to more frequent and severe events.
Research from the University of Chicago reveals that loneliness increases self-centeredness, which in turn contributes to further loneliness. This creates a negative feedback loop that can worsen social isolation. The study suggests targeting self-centeredness as part of an intervention to reduce loneliness may help break this cycle.
Researchers found that some trees promote fires to limit competition from better tree species, stabilizing savanna ecosystems. Savanna trees like longleaf pine shed needles, providing fuel for frequent low-intensity fires.
