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.....»»
Study reveals uniqueness of naturally occurring monodominant forests in the Republic of Congo
A recent study published in the journal Plant Ecology and Evolution gives valuable insights into forest stands of Gilbertiodendron dewevrei (G. dewevrei) in the Sangha Trinational region......»»
Adaptation of photosynthetic mechanism in air plants occurs through gene duplication, study finds
Researchers at the University of Vienna, along with collaborators from France, Germany, Switzerland and the U.S., have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Till.....»»
Aggressive wall lizard provides clues to understanding evolution
Body shape, color and behavior often evolve together as species adapt to their environment. Researchers from Lund University in Sweden have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
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.....»»
