Image 1 shows the U-net algorithm correctly identifying the iceberg, which is highlighted in red. In comparison, the k-means algorithm has incorrectly identified a cluster of smaller icebergs and ice fragments, shown in blue, as one large iceberg. That is revealed in image 2.

Scientists have trained an artificial intelligence (AI) system to accurately map—in one-hundredth of a second—the surface area and outline of giant icebergs captured on satellite images. The paper, titled “Mapping the extent of giant Antarctic icebergs with Deep Learning,” is published in The Cryosphere. It is a…

Researchers with the Translational Research in Neuroimaging and Data Science (TReNDs) Center at Georgia State have identified important new methods for accurately identifying possible biomarkers in adolescent brains that can reliably predict cognitive developments and psychiatric issues. A new study, published in Nature Mental Health, represents the first large-scale analysis of its kind in which researchers analyzed functional network connectivity (FNC) across scans and identified associations with a diverse range of health measures in children. Researchers believe that inferences about early cognitive and psychiatric behaviors in children may be made using these intra-subject variabilities as a useful biomarker. Researchers studied…

Microfossils from Western Australia may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth’s atmosphere and oceans, according to an international team of scientists. The findings, published in the journal Geobiology, provide a rare window into the Great Oxidation Event, a time roughly 2.4 billion years ago when the oxygen concentration increased on Earth, fundamentally changing the planet’s surface. The event is thought to have triggered a mass extinction and opened the door for the development of more complex life, but little direct evidence had existed in the fossil record before the…

Biochar, a charcoal made from heating discarded organic materials such as crop residues, offers a path to lowering atmospheric carbon dioxide (CO2). New maps, made from a first-of-its-kind high-resolution global dataset of crop residues, reveal areas where the residues may be sustainably used to produce biochar. The research finds that 12 countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%. The study, “Potential for…
