The ever-changing brain: Shining a light on synaptic plasticity
November 2019  |  Science News
Researchers have found that AMPA receptors form and disintegrate continually, within a fraction of a second, rather than existing as stable entities. The scientists' findings may help clarify early stages of synaptic plasticity: neural activity that is key for learning and memory.

Researchers develop method to isolate T cells primed for certain allergies or infections
November 2019  |  Science News
Researchers have now devised a way to identify T cells that share a particular target, as part of a process called high-throughput single-cell RNA sequencing. This kind of profiling can reveal the unique functions of those T cells by determining which genes they turn on at a given time. In a new study, the researchers used this technique to identify T cells that produce the inflammation seen in patients with peanut allergies.

Novel Fluorescence Lifetime Imaging Tool May Advance Cancer Care
November 2019  |  Science News
Scientists described and demonstrated a new technique for fluorescence lifetime imaging of tissue and cells in a fast and comprehensive manner, thus laying the groundwork for use in a clinical setting. They believe that FLI-Net is well suited to accurately quantify complex fluorescence lifetimes in cells and, in real time, in intact animals without any parameter settings.
