"That screen narrowed the list significantly, from 30,000 to about 10,000," Huang said. She then used what Zuker calls "a stroke of ingenuity" to reduce the list further.

"Using MIMS, we can image and quantify the fate of these molecules when they go into cells, where they go, and how quickly they are replaced," says Lechene. The method does not need staining or use of radioactive labelling. Instead, it is...Images develop clinical applications for new DESI technology

In our experiments, we will add guppies in sections of the stream that had none before to see if ecological interactions are independent of evolution and if these interactions impact all aspects of the ecosystem.

Because coral reefs are dying from rising ocean temperatures, increasing ocean acidity, and direct human damage, Oppenheimer said the findings offer yet another reason to protect these fragile offshore ecosystems. ...Fires fuel mercury emissions, University of Michigan study finds
