Study finds investors prefer good-looking male backed entrepreneurial ventures
Flies with brothers make gentler lovers
Flies living with their brothers cause less harm to females during courting than those living with unrelated flies, say Oxford University scientists.
Study suggests why, in some species, mere presence of males shortens females' lifespan
Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.
Two Y genes can replace the entire Y chromosome for assisted reproduction in mice
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from ...
Peacock's train is not such a drag
The magnificent plumage of the peacock may not be quite the sacrifice to love that it appears to be, University of Leeds researchers have discovered.
Researchers identify a pheromone in the urine of male tilapia fish that stimulates spawning in females
The exchange of chemical signals between organisms is considered the oldest form of communication. Acting as messenger molecules, pheromones regulate social interactions between conspecifics, for example, ...
Fish study links brain size to parental duties
Male stickleback fish that protect their young have bigger brains than counterparts that don't care for offspring, finds a new University of British Columbia study.
Population density and testes size: More than meets the eye
A team of researchers has discovered that changes in population density can affect the size of animals' testes and therefore impact on reproduction.
Genetically engineered fruit flies could save crops
Releasing genetically engineered fruit flies into the wild could prove to be a cheap, effective and environmentally friendly way of pest control according to scientists at the University of East Anglia and ...
How plants may be evolving to the lack of bees
Plants which used to have two types of male reproductive organs – to increase their chances for fertilisation – are reverting back to one type. And in some cases, they are becoming self-fertilising.
Flower's bellows organ blasts pollen at bird pollinators
A small tree or shrub found in mountainous Central and South American rainforests has a most unusual relationship with the birds that pollinate its flowers, according to a study reported in the journal Current Bi ...
Researchers find bundled team swimming in ant spermatozoa increases speed
Cricket fertility found to improve with age
UWA scientists researching the seminal fluid of field crickets (teleogryllus oceanicus) are a step closer to knowing why the insect's competitive fertilisation success increases with age.
Scientists wipe out malaria-carrying mosquitoes in the lab by creating male-only offspring
Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria.
