Using synchrotron rapid scanning X-ray fluorescence to map the distribution of trace metals in avian fossils over 120 million-year-old, researchers reconstruct the pigment patterns of their feathers—revealing some of the extinct birds' long-lost colo
These small membrane vesicles do much more than clean up a cell’s trash—they also carry signals to distant parts of the body, where they can impact multiple dimensions of cellular life.
A new study finds that more than two thirds of Americans approve of the use of stem cells in research aiming to cure serious diseases.
The optogenetic toolset is composed of genetically encoded molecules that, when targeted to specific neurons in the brain, enable the electrical activity of those neurons to be driven or silenced by light. When these opsins are expressed in the lipid
I the dark Arctic shallows one research finds heterotrophic marine bacteria doing a surprising amount of carbon fixing.
Exosomes are small membrane vesicles secreted by most cell types. Internal vesicles form by the inward budding of cellular compartments known as multivesicular endosomes (MVE). When MVE fuse with the plasma membrane, these internal vesicles are relea
