Both VEGF-C and VEGF-D can be activated by KLK3/PSA and Cathepsin D, producing two novel VEGF-C forms and the known VEGFR-2-specific form of VEGF-D.

After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

Seminal fluid harbours the as yet unknown mechanism that facilitates rapid adjustment of sperm velocity in response to changing sperm competition risk.

A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.

A functional genetics approach reveals a novel role for odorant binding proteins in post-mating processes, with complex mechanisms of evolutionary change across closely related insect species.

CLR01 is a small molecule that could be an effective topical microbicide to eliminate HIV (and other enveloped viruses), and to antagonize host-encoded amyloid fibrils that promote HIV infection.

The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

Ex vivo characterization of the interaction of human sperm with semen factors reveals that semen amyloids, previously discovered due to their ability to enhance HIV infection, serve a physiological function by promoting disposal of the defective sperm.

A novel paternal effect based on nicotine exposure reveals that offspring exhibit an adaptive, yet nonspecific, resistance to multiple toxins.

A change in social status can quickly lead to a change in the quality of the seminal fluid produced by a male Chinook salmon as he responds to increased reproductive competition from higher-status males.
