An organic molecule detected in the material from which a star forms could shed light on how life emerged on Earth, according to new research led by Queen Mary University of London.
New research from Case Western Reserve University in how dragonflies may adapt their wing color to temperature differences might explain color variation in other animals, from lions to birds. Further, the findings could also provide evolutionary biologists clues about whether rising global temperatures might adversely affect some species.
Humpback whales overwintering in feeding areas may sing complex, progressive songs which closely resemble those associated with breeding grounds, according to a study published Jan. 23, 2019, in the open-access journal PLOS ONE by Edda E. Magnúsdóttir and Rangyn Lim from the University of Iceland.
Research shows that rapid urbanization in São Paulo City, Brazil, is influencing wing morphology in the mosquitoes that transmit dengue and malaria.
A study, led by the University of Bristol, has shed some new light on how the beaks of birds have adapted over time.
Researchers from Aarhus University, Denmark, and Copenhagen Zoo have discovered that the human mutation rate is significantly slower than for our closest primate relatives. The new knowledge may be important for estimates of when the common ancestor for humans and chimpanzees lived -- and for conservation of large primates in the wild.
Professor Rony Paz of the Weizmann Institute of Science suggests that our brains are like modern washing machines -- evolved to have the latest sophisticated programming, but more vulnerable to breakdown and prone to develop costly disorders. He and a group of researchers recently conducted experiments comparing the efficiency of the neural code in non-human and human primates, and found that as the neural code gets more efficient, the robustness that prevents errors is reduced.
Having ancestors who were frequently exposed to stressors can improve one's own immune response to stressors, according to Penn State researchers. The results suggest that family history should be considered to predict or understand the health implications of stress.
A small change in the genetic makeup of the South African Cape bee turns the socially organised animal into a fighting parasite. This change ensures that infertile worker bees begin to lay their own eggs and fight other colonies. In the current issue of the journal 'Molecular Biology and Evolution', an international research team led by Martin Luther University Halle-Wittenberg (MLU) outlines for the first time the genetic basis for this rare phenomenon.
What happens to sex pheromones as new species emerge? New research publishing Jan. 22 in the open-access journal PLOS Biology studies sex pheromones in the fission yeast Schizosaccharomyces pombe, revealing an 'asymmetric' pheromone recognition system in which one pheromone operates extremely stringently whereas the other pheromone is free to undergo a certain degree of diversification, perhaps leading to a first step towards speciation.
