Male bats with high testosterone levels have large forearm crusts when females are fertile

Males may put a lot of effort into attracting females. Male peacocks flaunt eye-catching trains, but male bats, because they are active at night, may rely on females' sense of smell to draw them in. Three years ago, Victoria Flores, a predoctoral fellow at the Smithsonian Tropical Research Institute (STRI) in Panama, discovered that male fringed-lipped bats often have a sweet-smelling, crusty substance on their forearms. Because only males had crusts and primarily exhibited these crusts during the putative reproductive season, Flores speculated that crusts might play a role in mating. Now Mariana Muñoz-Romo, postdoctoral fellow at STRI and National Geographic Explorer, and her colleagues have evidence to prove it.

Tepary beans—a versatile and sustainable native crop

Agriculture accounts for more than a third of water use in the United States. In drier parts of the country, like the southwestern U.S., that fraction can be much higher. For example, more than 75% of New Mexico's water use is for agriculture.

Microbes in dental plaque look more like relatives in soil than those on the tongue

From the perspective of A. Murat Eren, Ph.D., the mouth is the perfect place to study microbial communities. "Not only is it the beginning of the GI tract, but it's also a very special and small environment that's microbially diverse enough that we can really start to answer interesting questions about microbiomes and their evolution," said Eren, an assistant professor in the Department of Medicine at the University of Chicago.
