How big can a gene be? Ten years ago in the early days of genome sequencing, researchers scoured the genomes of 580 bacterial and archaeal species for large genes. They found that 0.2% of all genes identified are longer than 5,000 bases and 80 of them are “giant genes,” those larger than 15,000 bases. To…
Though the heat of the chili pepper has taken our culinary adventures to great heights, the spiciness of chili peppers was not designed to attract hungry diners.

Have you ever wondered what microbes are brewing in your showerhead? The Showerhead Microbiome Project is finding out! This project, run by a multi-institution group of researchers, is identifying what microbes live in showerheads and how the physical properties of the water and showerhead type may influence the microbial communities. But why should we even…
While most of us worry about the ripeness of our bananas, Marcos Voutsinos has been preoccupied with something else: the banana freckle. Despite its innocuous name, banana freckle is actually a fungal disease caused by the fungus Phyllosticta cavendishii and characterized by “freckles” of fungus on the banana fruit, leaves, and stems. The fruiting bodies…
