Memory fail controlled by dopamine circuit, study finds

by  The Scripps Research Institute Scripps Research, Florida Neuroscience Professor Ron Davis, PhD, has discovered a mechanism underlying transient forgetting. Credit: Scripps Research In a landmark neurobiology study, scientists from Scripps Research have discovered a memory gating system that employs the neurotransmitter dopamine to direct transient forgetting, a temporary lapse of memory which spontaneously returns. The study adds a new pin to...

Cancer can be precisely diagnosed using a urine test with artificial intelligence

NATIONAL RESEARCH COUNCIL OF SCIENCE & TECHNOLOGY IMAGE: The set of sensing signals collected for each patient were then analyzed using ML to screen the patient for PCa. Seventy-six urine samples were measured three times, thereby generating 912 biomarker signals or 228 sets of sensing signals. We used RF and NN algorithms to analyze the multimarker signals....

Spontaneous cell fusions amplify genetic diversity within tumors

by  H. Lee Moffitt Cancer Center & Research Institute Credit: CC0 Public Domain Evolution within groups of tumor cells follows the principles of natural selection, as evolution in pathogenic microbes. That is, the diversity of cellular characteristics within a group leads to differences in the ability of cells to survive and divide, which leads to selection for cells...
