A team of researchers working on a Carnegie expedition in Australia’s Great Barrier Reef has documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown. 

Proteins are the machinery that accomplishes almost every task in every cell in every living organism. The instructions for how to build each protein are written into a cell’s DNA. But once the proteins are constructed, they must be shipped off to the proper place to perform their jobs. New work describes a potentially new pathway for targeting newly manufactured proteins to the correct location. 

Hydrogen responds to pressure and temperature extremes differently. Under ambient conditions hydrogen is a gaseous two-atom molecule. As confinement pressure increases, the molecules adopt different states of matter—like when water ice melts to liquid. Scientists, including Carnegie’s Alexander Goncharov, combined hydrogen with its heavier sibling deuterium and created a novel, disordered, “Phase IV”-material. The molecules interact differently than have been observed before, which could be valuable for controlling superconducting and thermoelectric properties of new hydrogen-bearing materials.

When it comes to cellular architecture, function follows form. Plant cells contain a dynamic cytoskeleton which is responsible for directing cell growth, development, movement, and division. So over time, changes in the cytoskeleton form the shape and behavior of cells and, ultimately, the structure and function of the organism as a whole. New work hones in on how one particular organizational protein influences cytoskeletal and cellular structure in plants, findings that may also have implications for cytoskeletal organization in animals.
