  • Urbanization changes shape of mosquitoes' wings January 22, 2019
    Research shows that rapid urbanization in São Paulo City, Brazil, is influencing wing morphology in the mosquitoes that transmit dengue and malaria.
  • How sex pheromones diversify: Lessons from yeast January 22, 2019
    What happens to sex pheromones as new species emerge? New research 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.
  • How much rainforest do birds need? January 22, 2019
    Researchers have carried out research in Southwest Cameroon to assess which proportion of forest would be necessary in order to provide sufficient habitat for rainforest bird species.
  • Bifacial stem cells produce wood and bast January 22, 2019
    So-called bifacial stem cells are responsible for one of the most critical growth processes on Earth -- the formation of wood. By alternately developing into wood and bast cells, these stem cells are thus starting points for forming wood as well as generating plant bast fibers. A team of researchers were recently able to demonstrate […]
  • Effective strategies for safeguarding CRISPR gene-drive experiments January 22, 2019
    Researchers have demonstrated for the first time how two molecular strategies can safeguard CRISPR gene-drive experiments in the lab, according to a new study.
  • New skin test detects prion infection before symptoms appear January 22, 2019
    Prions can infect both humans and animals, causing Creutzfeldt-Jakob disease (CJD) in humans, mad cow disease in cattle, and chronic wasting disease in elk and deer. The infectious, misfolded protein particles often go undetected as they destroy brain tissue, causing memory loss, mobility issues, and ultimately death. Preclinical detection of prions has proven difficult, but […]
