Shaping Future Children, Sex Selection, and “Normal” Human Capacities

Bioethics, EarlyView.
ABSTRACT If we think that parents have an obligation to have a healthy child then we need to know what counts as healthy, when male and female children are born with very different capacities. If we give up on the idea that our obligations to use technologies of genetic selection are discharged once we try to secure the birth of a healthy child, as ...

Computational Modelling of Sperm Behaviour in a 3D Virtual Oviduct [PDF]

, 2011
The processes by which individual sperm cells navigate the length and complexity of the female reproductive tract and then reach and fertilise the oocyte are fascinating. Numerous complex processes potentially influence the movement of spermatozoa within

A Fly in the Ointment? Non‐Target Fly Pest Benefits From Reduction in Ivermectin During Targeted Selective Treatment

Entomologia Experimentalis et Applicata, EarlyView.
Targeted Selective Treatment (TST) can reduce the rate of resistance development in livestock gastrointestinal nematodes but can also reduce the effects of anthelmintics on non‐target organisms. Most studies of non‐target anthelmintic effects focus on beneficial species.

A High‐Resolution Method Using Individual Females to Assess the Competitiveness of Sterile Drosophila suzukii Males Under Semi‐Controlled Conditions

Entomologia Experimentalis et Applicata, EarlyView.
A high‐resolution, novel method to assess the sexual competitiveness of sterile mass‐reared Drosophila suzukii males is calibrated and illustrated using different laboratory and wild type strains. Isolation of individual females after semi‐controlled cage competition tests and subsequent observation of their progeny showed that sterile males from two ...
