RESEARCH ARTICLES

  • Open Access
    Testing a key assumption in animal communication: between-individual variation in female visual systems alters perception of male signals
    Kelly L. Ronald, Amanda L. Ensminger, Matthew D. Shawkey, Jeffrey R. Lucas, Esteban Fernández-Juricic
    Biology Open 2017 6: 1771-1783; doi: 10.1242/bio.028282

    Summary: Animal communication studies often assume receiver perception is equal across individuals; we found females vary in their visual physiology and perception of male signals which could influence their mating decisions.

  • Open Access
    A computational study on the influence of insect wing geometry on bee flight mechanics
    Jeffrey Feaster, Francine Battaglia, Javid Bayandor
    Biology Open 2017 6: 1784-1795; doi: 10.1242/bio.024612

    Summary: A morphologically accurate insect wing cross-section is compared with common cross-sections reported in the literature. It was found that misrepresenting the insect wing cross-section can result in different aerodynamics. This article has an associated First Person interview with the first author of the paper as part of the supplementary information.

  • Open Access
    The addition of a developmental factor, unc-62, to already long-lived worms increases lifespan and healthspan
    Dror Sagi
    Biology Open 2017 6: 1796-1801; doi: 10.1242/bio.027433

    Summary: This work uses a modular approach to combine five genes together to build worms that are long lived and much healthier than control animals, without a significant reduction in fertility. This article has an associated First Person interview with the first author of the paper as part of the supplementary information.

  • Open Access
    Cohesin mediates Esco2-dependent transcriptional regulation in a zebrafish regenerating fin model of Roberts Syndrome

Biology Open and COVID-19

We are aware that the COVID-19 pandemic is having an unprecedented impact on researchers worldwide. The Editors of all The Company of Biologists’ journals have been considering ways in which we can alleviate concerns that members of our community may have around publishing activities during this time. Read about the actions we are taking at this time.

Please don’t hesitate to contact the Editorial Office if you have any questions or concerns.


2020 at The Company of Biologists

Despite 2020’s challenges, we achieved a lot at The Company of Biologists. In the midst of the pandemic, we have seen long-term projects and new ventures come to fruition. Read our full lowdown of 2020.


Interview- Sebastian Markert

Sebastian Markert is first author of a paper in BiO using C. elegans to model amyotrophic lateral sclerosis. In an interview, he talks about the potential implications of his work and his future plans.


Three communities to support biologists to everywhere

Online communities have never been more important. If you’re looking for somewhere to meet fellow scientists, take part in topical discussions and find virtual events in your field, take a look at each of our community sites:

  • The Node: the community site for and by developmental biologists
  • preLights: the preprint highlights service run by the biological community
  • FocalPlane: the community site for microscopists and biologists alike
