A multi-institutional team led by North Carolina State University researchers has found that using recently released criteria for the diagnosis of canine glioma resulted in strong diagnostic consensus among pathologists.
Research has established that there are traces of Neandertal DNA in the genome of modern humans.
Scientists at the University of Bristol have uncovered the deadly workings of a carnivorous plant.
They are always there, dwelling in the water, where they play a key role in food webs, in cycling of nutrients, matter and energy, and water purification. However, as happens with organisms that tend to be inconspicuous and often invisible to the naked eye, society mostly neglects them, and forgets their huge importance in providing support and stability of aquatic ecosystems. What is even more problematic, we also forget that they are exposed to a wide range of threats from human activities. Without proper conservation measures, their populations can decline and go extinct just like all of the other, more conspicuous aquatic organisms, with unforeseen consequences for marine and freshwater ecosystems. This was the object of a study by an international team led by researchers from the Biology Centre of the Czech Academy of Sciences, as well as from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in Germany, and the University of Coimbra in Portugal.
The peptide is used by legumes to control nitrogen-fixing bacteria; it may also offer leads for treating patients with too much heme in their blood.
Prokaryotes can detect hallmark viral proteins and trigger cell death through a process seen across all domains of life.
Bird species whose males perform aerial displaying inhabit open rather than closed (forest) environments and are more likely to have multiple mates. They usually have more elongated wings, which is related to the fact that they migrate longer distances, and breed at higher latitudes, i.e. further from the equator. In addition, the aerial displaying seems to be relatively common in generally small passerine species with brightly coloured plumage. All of this suggests that the evolution of aerial displays in passerine is the result of both sexual and natural selection, as scientists from the Institute of Vertebrate Biology of the Czech Academy of Sciences and the Faculty of Science of Charles University have found in a recent comprehensive analysis.
Mathematical modeling speeds up the process of programming bacterial systems to self-assemble into desired 2D shapes.
Today we commonly encounter contactless RFID chips in a number of products, but can similar technology be implemented at the molecular level? The answer is yes. The principle of molecular encoding conceived by Miloslav Polášek and his team at IOCB Prague represents a novel method on the frontier of chemistry and modern technologies.
Scientists at the University of Bristol have discovered that the vast anatomical variety of fungi stems from evolutionary increases in multicellular complexity.
An international team of researchers have discovered that a mysterious microscopic creature from which humans were thought to descend is part of a different family tree.
Sexual enjoyment in the years following childbirth is unaffected by the way in which the baby is delivered, according to new research.
Male bottlenose dolphins form the largest known multi-level alliance network outside humans, an international team led by researchers at the University of Bristol have shown.
Researchers discover a novel mutualism between fungi and insects
Cornell University research has found that a commonly used chemotherapy drug called, etoposide, stops enzymes that lead to cancer cells growing.
A team of researchers has found that arginine, an amino acid produced naturally by our bodies, is a key nutrient for cancer cells, and depriving those cells of the food they crave could make tumors more susceptible to the body’s natural immune response.
Researchers from the Cornell Lab of Ornithology and the University of Massachusetts, Amherst have developed a new computer model that uses machine learning to predict the migratory patterns of birds.
A study by researchers at Cornell University has found that white-tailed deer are carrying variants of SARS-CoV-2 that, at one time, circulated among humans but are currently extinct.
