Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study from scientists with the Smithsonian's National Museum of Natural History.
The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham University, UK, has used the James Webb Space Telescope (JWST) to find evidence of bar formation when the universe was only a few billion years old.
The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become "consorts" that fight for mating opportunities. Those that hatch later become "sneakers," which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life.
Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one.
A new study finds that "sunny day flooding," which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding.
Locations around the globe are experiencing climate disasters on a regular basis. But some of the most marginalized populations experience disasters so often it has come to be normalized.
In a comparison of differently sized poultry farms, researchers at North Carolina State University found that rates of Salmonella in fecal and environmental samples were more prevalent on larger commercial farms than on smaller backyard farms.
To properly protect forests and evaluate the state of natural resources, conservation practices and environmental policies, it is important to have accurate information on an area's forest extent.
