"Identifying Chromosome End Targets for Degenerative Disease Prevention"

Originally Published 1 year ago — by Phys.org

A new study published in Science reveals that telomere lengths vary across different chromosome ends, challenging the previous understanding of a singular telomere-length range. The research, led by UC Santa Cruz professor Carol Greider, utilized nanopore sequencing to make precise measurements and found that specific chromosome ends may be the first to trigger stem-cell failure. The study suggests that the regions adjacent to telomeres could serve as potential targets for new drugs to prevent degenerative diseases, and the nanopore sequencing technique has widespread potential for use in research, diagnostics, and drug development.

The Role of Dendrites in Brain Computation

Originally Published 2 years ago — by Neuroscience News

A new study challenges the long-standing hypothesis in neuroscience that the soma (cell body) of neurons is the primary computational element in the brain, suggesting that dendrites also play a crucial role. Researchers conducted experiments under non-physiological conditions and found that dendrites control neuron features such as firing frequency and stimulation threshold. This discovery could reshape our understanding of brain states, learning processes, and degenerative diseases. The results call for a re-examination of the origin of degenerative diseases and question the traditional attribution of awake and sleep states to the soma.
