Study identifies proteins that modulate life span in worms

Researchers at the Stanford University School of Medicine have identified a new group of proteins involved in determining the life span of laboratory roundworms. Blocking the expression of one member of the group can extend ...

Is sex primarily a strategy against transmissible cancer?

One of the greatest enigmas of evolutionary biology is that while sex is the dominant mode of reproduction among multicellular organisms, asexual reproduction appears much more efficient and less costly. However, in a study ...

(Phys.org)—A team of researchers working at Monash University in Australia has found an example of a rodent that has a human-like menstrual cycle. As the team notes in their paper uploaded to the preprint server bioRxiv, ...

Fungal sex can generate new drug resistant, virulent strains

Though some might disagree, most biologists think the purpose of sex is to create diversity among offspring. Such diversity underpins evolution, enabling organisms to acquire new combinations of traits to adapt to their environment.

New study reveals responses of genes in females to sex

Sex can trigger remarkable female responses including altered fertility, immunity, libido, eating and sleep patterns—by the activation of diverse sets of genes, according to research from the University of East Anglia.

Malaria parasite goes bananas before sex: new study

(PhysOrg.com) -- New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine ...
