Cooperative breeders, where we count on the help of others to raise offspring,is not unique to humans. It may only appear that way.

A new paper amassed data from 90 human populations comprising 80,223 individuals from many parts of the world — both historical and contemporary. They compared the records for men and women to lifetime data for 45 different nonhuman, free-ranging mammals. The argue that humans are a non-exceptional species of mammal. Says first author Cody Ross, PhD, anthropologist at the Max Planck Institute; “we can quite successfully model reproductive inequality in humans and nonhumans using the same predictors.”

A new demography paper argues that there is a reason more black women have voted for Democrats than men have since 1980 - more black men are in jail.

CRISPR/Cas9 technology has led to a “homing gene drive system” based on a specific Drosophila suzukii gene called doublesex that can suppress populations of D. suzukii vinegar flies – the “spotted-wing Drosophila” that devastate soft-skinned fruit in North America, Europe and parts of South America.

A new study suggests alcoholism coupled with genetic susceptibility is associated with changes to gene expression indicative of disease progression in the brains of mice that are genetically predisposed to Alzheimer’s. When repeatedly exposed to intoxicating amounts of alcohol, these mice showed signs of cognitive decline approximately two months sooner than they usually would.

If you have been to a zoo and been around our primate evolutionary cousins with kids, you may have had an awkward moment or two. They are going to masturbate, and don't care who's watching.

A new study says more is better. The Postcopulatory Selection Hypothesis believes it helps shed low-quality semen while the The Pathogen Avoidance Hypothesis believes it may reduce the risk of contracting sexually-transmitted infections. Primates have been doing it for at least 40 million years so something keeps it going.

A traditional endoscopy, while valuable for detecting high-risk lesions, is an expensive, invasive procedure. There are ingestible cameras but are not controlled by physicians, they are just swallowed and the body does the rest.
