Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually ...
When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by ...
With every new particle accelerator built for research, scientists have an opportunity to push the limits of discovery. But this is only true if new particle accelerators deliver the desired performance—no small feat in ...
Trains carrying loads of coal bring with them higher rates of asthma, heart disease, hospitalization and death for residents living nearest the rail lines, according to a new study from the University of California, Davis.
Many of us would love the superpower to fly, and for good reason: Flight offers a crucial evolutionary advantage. Flying enables an animal to travel large distances quickly, in search of food and new habitats, while expending ...
