Same-Sex Mating Discovered in a Toxic Fungus
...e unisexual fruiting occurred strictly through the asexual
division of cells into identical clones, Heitman s..., the researchers found that, rather than being an asexual
process, the hallmarks of mating occur during fruiting of alpha isolates. Unisexual fruiting involve...
Mosquitoes are more attracted to individuals infected with malaria
...e malaria, one infected with the non-transmissible asexual
stage of the disease, and one with no infection. A device called an olfactometer wafted the odours of each participant towards the mosquitoes. Researchers measured which child most attracted the hungry bugs. Koella et al. found that individuals attra...

Malaria vaccine prompts victims' immune system to eliminate parasite from mosquitoes
...ction, these cells, for the most part, exist in an asexual
form. Some of the Plasmodium cells, however, transform into gametocytes—the sexual forms of the parasite that are equivalent to sperm and eggs. Fertilization takes place in the mosquito gut, after which the parasite imbeds itself in the gut lini...
Study of planarians offers insight into germ cell development
...itself by means of fission. In looking at nanos in asexual
individuals of this species, the researchers made the surprising discovery that these asexual
individuals also express nanos and produce germ cells. Some other mechanism, as yet unknown, prevent...

Asexual worm quickly adapts to soil contamination
...l The rapid adaptation to the environment in an asexual
species is an interesting finding. It contradicts the general opinion that asexual
species have low adaptive potential and that they adapt to stress less easily than sexual species. A...
