Only one-quarter of Colombia's protected areas effectively protect freshwater fishes, researchers find

Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays are interpreted across fields of physics, chemistry, biology and materials science, new research reveals. Researchers say the discovery can help scientists measure X-rays more precisely and reliably, and improve our understanding of common materials, from battery materials to biological proteins.

In most bumblebee species, the queens spend their winters buried underground in a tiny cavity the size of a grape. For six to nine months, they enter a deep sleep-like state called diapause, waiting for spring.

The way a key cellular motor works at an atomic level has been uncovered by simulations conducted by RIKEN biophysicists. This finding, published in the journal Proceedings of the National Academy of Sciences, provides important insights into how mechanical force is generated in cells.

Emissions of two major pollutants have steadily decreased on Salt Lake City roads over the past two decades, while levels of carbon dioxide emissions, a related gas blamed for climate change, remained steady, according to a new study by University of Utah atmospheric scientists conducted in partnership with the federal National Oceanic and Atmospheric Administration. The research is published in the journal Atmospheric Environment.
