Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours—sometimes more than a day—in a reversible intermediate state, ...

Researchers have uncovered how a structure in bodily carbohydrates (sugar chains or "glycans") that regulates how they attach themselves to other molecules interacts with key enzymes, and in so doing can contribute to a range ...

A question left unanswered in a biologist's lab notebook for 40 years has finally been explained, thanks to a little fish that couldn't wriggle its tail.

Colossal undersea mountains, towering up to thousands of meters high, stir up deep sea currents: impacting how our ocean stores heat and carbon.

An international team of researchers led by the University of Adelaide has projected future marine heat waves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen.

Rural livelihoods are quite intertwined with urban centers, with mid-sized cities playing an extraordinary role in providing required services, including for food security, agricultural livelihoods and viable rural development, ...

More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of ...

Atmospheric aerosol particles act as a key modulator of Earth's climate. New particle formation (NPF) from condensable gas molecules is the fundamental source of most atmospheric particles.

Lichen, which people may think of as a single organism, is in fact a community of several species that depend on each other for survival. Lichen symbiosis includes at least one fungus and one alga, along with other fungi ...

Transferring mitochondria from a patient's healthy skeletal muscle to damaged, ischemic heart tissue has been shown to restore heart muscle, increase energy production, and improve ventricular function.

Researchers have gained new knowledge of how drugs bind to connexin molecules. These molecules form channels that allow neighboring cells to send direct messages to one another. Dysfunctions of these channels are involved ...

With the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability, research conducted in the laboratory of Keith Slotkin, Ph.D., and his colleagues in ...
