Researchers create method to detect cases of anemia in archaeological remains

Original micro-CT resolution(a) versus adjusted resolution for comparison to CT images(b) for the same individual. Sagittal micro-CT (a) and CT (b) reconstructions. Credit: Journal of Archaeological Science (2024). DOI: 10.1016/j.jas.2024.105942 Diagnosing anemia in living people is typically a matter of a routine blood test. Retrospectively diagnosing anemia in people who died decades or even centuries … Read more

How archaeologists use hazelnuts to reconstruct ancient woodlands

How archaeologists use hazelnuts to reconstruct ancient woodlands

An archaeologist takes samples of pollen found in soil to understand the changing vegetation of a site: a companion technique to the authors’ analysis of hazelnut shells. Credit: Nils Forshed. If we could stand in a landscape that our Mesolithic ancestors called home, what would we see around us? Scientists have devised a method of … Read more

New study highlights overwhelming increase in dry springs

New study highlights overwhelming increase in dry springs

Credit: Unsplash/CC0 Public Domain New research from The Meadows Center for Water and the Environment at Texas State University uncovers a concerning decline in the state’s groundwater resources, finding that the number of dry springs has nearly tripled since the early 1980s. Co-authored by Robert E. Mace, Ph.D., Meadows Center Executive Director, and Nohemi Galaviz, … Read more

Building bionic jellyfish for ocean exploration

This time-lapse composite image shows a biohybrid robot jellyfish descending through the three-story tank designed for testing the swimming abilities of the modified creatures. Credit: Caltech Jellyfish can’t do much besides swim, sting, eat, and breed. They don’t even have brains. Yet, these simple creatures can easily journey to the depths of the oceans in … Read more

How climate change risks increase at a national scale as the level of global warming increases

How climate change risks increase at a national scale as the level of global warming increases

Credit: Unsplash/CC0 Public Domain A major research program led by the University of East Anglia (UEA) has quantified how climate change risks to human and natural systems increase at a national scale as the level of global warming increases. A collection of eight studies—all focusing on Brazil, China, Egypt, Ethiopia, Ghana and India—shows that the … Read more

AI technique ‘decodes’ microscope images, overcoming fundamental limit

AI technique ‘decodes’ microscope images, overcoming fundamental limit

Credit: Nano Letters (2024). DOI: 10.1021/acs.nanolett.3c04712 Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope’s probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe’s … Read more

Overcrowding increases tree mortality, perhaps explaining higher biodiversity in tropical forests

Overcrowding increases tree mortality, perhaps explaining higher biodiversity in tropical forests

Credit: CC0 Public Domain When a tree is surrounded by many similar individuals, its mortality increases, which is probably caused by specialized pathogens or herbivores. This effect occurs in forests all over the world, but is more pronounced in rare tropical tree species, which could contribute to the astonishing tree species diversity of tropical forests. … Read more

Researchers develop a more precise carbon footprint measurement method

Researchers develop a more precise carbon footprint measurement method

Credit: CC0 Public Domain Bayreuth researchers want to calculate the carbon footprint of companies more accurately in the future. The term “carbon footprint” refers to the recording of climate-impacting greenhouse gases and the compilation of these in a greenhouse gas balance. For more precise calculations, Nora Kuhn compared 8,500 products in her bachelor’s thesis at … Read more
