Credit: William Barichivich, USGS A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the U.S. Geological Survey. Frogs and salamanders are currently among the most threatened groups

Pictured is Diploscapter pachys (D. pachys), a newly sequenced roundworm that is approximately one-third of a millimeter long and one of a very few known animals that have only a single chromosome.

A side-by-side comparison shows better heat and drought tolerance in thale cress plants whose level of a specific RNA was increased.

The discovery could

Researchers have assembled the California Academy of Sciences’ first-ever animal genome after sequencing the

The Hill Dweller Rubber Frog, Pristimantis bounides, is known from two sites at elevations of 10,991 feet and 11,362 feet. The species name “bounides” is derived from the Greek noun “bounos,” which means “dweller of the hills” and refers to the habitat of the mountain forests where this frog was found. It is an area

University of British Columbia researchers conducted playback experiments by hanging wireless speakers in the trees and broadcasting songs from related subspecies. Credit: University of British Columbia Two birds that look the same, but have songs so different they can’t recognize each other, should be considered distinct species, suggests new University of British Columbia (UBC) research.

This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal lineage, researchers from the University of Vienna have now come to

Researchers from the University of Tsukuba, the National Agriculture and Food Research Organization (NARO) and Yokohama City University, Japan, altered the flower

Scientists have discovered a new way to convert human skin cells directly into motor neurons (above). The technique, developed at Washington University School of Medicine in St. Louis, could help researchers better understand diseases of motor neurons, such as amyotrophic lateral sclerosis. Human motor neurons are difficult to study since they can’t be taken from

University of Rochester researchers Jessica Cantlon and Stephen Ferrigno determined that non-human primates exhibited metacognitive illusions after they observed primates completing these series of steps on a computer.
