A gene associated with courtship behavior in fruit flies does not operate the same way in two different fruit fly species, a new study finds. The work demonstrates that conserved genes—the same genes found across species—do not necessarily have the same f

Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. In a paper published today, March 21, in the Zoological Journal of the Linnean

What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does divers

Blood vessels engineered from stem cells could help solve several research and clinical problems, from potentially providing a more comprehensive platform to screen if drug candidates can cross from the blood stream into the brain to developing lab-grown

A researcher from The University of Queensland has discovered a remarkable new genus of fluffy longhorn beetle while camping within a rainforest in the Gold Coast hinterland.

When you are reading this article, there are multiple hormones working diligently inside your body to stabilize your health status. Just as in human beings, it is impossible for plants to grow and reproduce without being regulated by phytohormones. One of

Tropical Heliconius butterflies are well known for the bright color patterns on their wings. These striking color patterns not only scare off predators—the butterflies are poisonous and are distasteful to birds—but are also important signals during mate s

Many important medicines, such as antibiotics and anticancer drugs, are derived from natural products of bacteria. The enzyme complexes that produce these active ingredients have a modular design that makes them ideal tools for synthetic biology. By explo

Researchers from the University of Southampton have developed technology to help scientists observe proteins in motion. Understanding how proteins move will allow novel drugs to be designed.

A Purdue University-led research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells.

A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United

Touchscreens have long been integral to our everyday life—humans use them to work, play, talk with loved ones and snag Lightning Deals on Prime Day. In recent years, they've shown potential for the animal kingdom as well, leading to a growing body of aca
