The evolution of axial patterning
Body axes are molecular coordinate systems along which regulatory genes are activated. These genes then activate the development of anatomical structures in correct locations in the embryo. Thus, the body ensures that we do not develop arms on our he.....»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Researcher finds that wood frogs evolved rapidly in response to road salts
When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research published in Ecology and Evolution a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin Senior Endowed.....»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
International study produces a comprehensive "tree of life" for flowering plants
With their own botanical collection material and their research knowledge on the evolution of cruciferous plants (plants of the cabbage family), bioscientists at Heidelberg University have contributed to a large-scale international study that has pro.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
Advances in understanding the evolution of stomach loss in agastric fishes
Living beings can evolve to lose biological structures due to potential survival benefits from such losses. For example, certain groups of ray-finned fishes show such regressive evolution—medakas, minnows, puffera, and wrasses do not have a stomach.....»»
Same species, different sizes: Rare evolution in action spotted in island bats
A University of Melbourne researcher has spotted a rare evolutionary phenomenon happening rapidly in real time in bats living in the Solomon Islands......»»
RNA"s hidden potential: New study unveils its role in early life and future bioengineering
The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose nucleic acid (DNA) template to a ribose nucleic ac.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Researchers identify genetic variant that helped shape human skull base evolution
Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution o.....»»
First evidence of human occupation in lava tube cave in Saudi Arabia
Recent strides in interdisciplinary archaeological research in Arabia have unveiled new insights into the evolution and historical development of regional human populations, as well as the dynamic patterns of cultural change, migration, and adaptatio.....»»
Amazon butterflies show how new species can evolve from hybridization
If evolution was originally depicted as a tree, with different species branching off as new blooms, then new research shows how the branches may actually be more entangled. In "Hybrid speciation driven by multilocus introgression of ecological traits.....»»
Evolution"s recipe book: How "copy paste" errors led to insect flight, octopus camouflage and human cognition
Seven hundred million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today's standards, the animal had a front and a back, a top and a bottom. This was a groundbreaking adaptation at the ti.....»»
ShadowDragon Horizon enhancements help users conduct investigations from any device
ShadowDragon announced significant enhancements to its Open-Source Intelligence Investigative platform Horizon. These updates represent a milestone in the evolution of investigative technology, offering capabilities to streamline investigative proces.....»»
Ivanti empowers IT and security teams with new solutions and enhancements
Ivanti released Ivanti Neurons for External Attack Surface management (EASM), which helps combat attack surface expansion with full visibility of external-facing assets and actionable intelligence on exposures. With the evolution of Everywhere Work c.....»»
The evolving attitudes of Gen X toward evolution
As the centennial of the Scopes Monkey Trial of 1925 approaches, a new study illustrates that the attitudes of Americans in Generation X toward evolution shifted as they aged......»»
Study shedding new light on Earth"s global carbon cycle could help assess liveability of other planets
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth—and it could help assess which other planets can develop life, ranging from plants to animals and humans......»»
Study explores changing design of birdfeeders as influenced by unwanted guests
The first birdfeeders were made in the 19th century, and their design rapidly evolved during the 20th century. Researchers at the University of Helsinki and Aalto University consider the evolution of the birdfeeder to be an example of multispecies de.....»»
Bias distribution and regulation in photoelectrochemical overall water-splitting cells
The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in new catalysts, characterization methods and reaction mechanisms. Compared with the hydrogen evolution reaction (HER), the.....»»
