Archaeologists have long known how to extract millennia-old stories from a single tooth buried in an ancient ruin—and now geneticists have the tools to join them. Advances made in the last several years have enabled researchers to sequence tiny amounts of DNA preserved in very old specimens, such as the material inside a tooth from…

The fastest-evolving genes in eukaryotes commonly encode reproductive proteins—and the rate at which genes for male reproductive proteins change, in particular, often vastly outstrips the rate of change across the genome as a whole. A recent paper in G3: Genes|Genomes|Genetics describes an unusual exception: the amino acid sequences of the most abundant sperm proteins in…

Whether it’s a battle over territory or a brawl over a sports game, aggressive behavior is a hallmark of the animal kingdom. The influence genetics has on aggression is undeniable—but the process of determining the genes involved has been frustratingly slow. To better understand genetic factors involved in aggression, some researchers have turned to male…

Corn feeds millions of people, and its low cost makes it particularly important in developing countries. However, it can’t be relied on as the sole source of protein for either humans or livestock because—like most cereals—corn is low in certain essential amino acids. In the 1960s, a type of corn was discovered with boosted levels of…

When a noni fruit ripens, it stinks like old cheese—or even vomit. Familiar to many in the form of expensive juices sold as health supplements, this pungent fruit is engaged in a slow-motion arms race with would-be insect pests. Fruit flies are unable to feast on noni—scientific name Morinda citrifolia—because the fruit is dosed with…

Every scientist is familiar with the p-value: it’s one of the most commonly used metrics in statistics to evaluate the likeliness that an observed relationship is due to chance. Typically, a cutoff is set at p=0.05, such that any p-value of greater than 0.05 means the result is deemed “not statistically significant”—a heartbreaking outcome for…

Mutations that disrupt the gene BRCA2 dramatically increase the odds of developing breast and ovarian cancer—but such mutations aren’t enough to cause cancer on their own. To turn normal cells cancerous, some of BRCA2’s genetic interactors must also mutate. In an article recently published in GENETICS, Ding et al. sought to identify some of these genes.…
