A team of American Museum of Natural History researchers has created a computational model capable of predicting whether or not organisms have the ability to 'eat' other cells through a process known as phagocytosis. The model may be a useful tool for large-scale microbe surveys and provides valuable insight into the evolution of complex life on Earth, challenging ideas put forward in recent studies.
Millions of plastic pellets are leaking out into the environment from a manufacturing site in Stenungsund. This has been shown by a new study conducted by researchers at the University of Gothenburg. Despite several international and national sets of regulatory frameworks, the leaking continues.
Postnatal depression (PND) can impact the quality of relationships between mother and child into adult life, and have a negative influence on the quality of relationships between grandmothers and grandchildren, new research at the University of Kent has discovered.
An analytical article based on the study of morphologic and chemical composition of particulate matter in motorcycle engine exhaust was published in the respected scientific journal Toxicology Reports. The group of authors was supervised by Aristidis Tsatsakis, a foreign member of the Russian Academy of Sciences and Doctor Honoris Causa of the Far Eastern Federal University, and Kirill Golokhvast, doctor of biology and Provost for Research at FEFU. The study was supported with a grant of the Russian Science Foundation.
All extreme-altitude birds have evolved especially efficient systems for delivering scarce oxygen to their tissues. But a new study led by the University of Nebraska-Lincoln has found that these birds often evolved different blueprints for assembling the proteins -- hemoglobins -- that actually capture oxygen in the Himalayas and Andes.
Bacteria play a major role in cleaning up oil spills and mitigating its environmental impacts. In a review published in Science of the Total Environment, researchers from Aarhus University, Denmark, examine the major limiting factors for microbial degradation in Arctic environments.
Dumbo octopuses live at a depth of thousands of meters in the oceans. A rare spectacle now provides further insight: a scientist filmed a dumbo octopus hatching from its egg. Based on these video and MRI scans of the internal organs, researchers from the Delaware Museum of Natural History, the University of Bonn, the University Hospital Münster, and the Woods Hole Oceanographic Institution document a surprising similarity of the hatchling with adult animals.
Problem-solving powers may help to explain why grey squirrels have taken over from native red squirrels in the UK, new research says.
Clonal ants appear to be diverse in responding to sweetened water, suggesting epigenetic regulation in behavioral variation and colony survival.
Overfishing and environmental change have pushed abalone species on the US west coast to the edge of extinction. Now a fatal disease threatens their recovery. But new research shows that some abalone species may be less susceptible to the disease than others, providing initial data that could help map where abalone could survive and thrive despite the disease.
