Dates in a Cave

TL Dates for the Neanderthal Site of the Amud Cave, Israel

Age-estimates ranging from 50 to 70 ky were obtained for the Mousterian deposits of Amud Cave in Israel from thermoluminescence measurements performed on 19 burnt flints. The late dates obtained for the stratigraphic layers bearing hominid remains confirm the evidence for the late presence of Neanderthals in the Levant. The dates enable a more effective comparison of the lithic assemblages from...

PTRF Triggers a Cave In

Caveolae are small membrane invaginations important for cell signaling that are characterized by the presence of caveolin proteins. Hill et al. (2008) have now identified PTRF as a new constituent of the caveolar coat. In the absence of PTRF, caveolae flatten and caveolin-1 is released into the cell membrane, where it is rapidly internalized and degraded.

Title : Inferring node dates from tip dates in fossil

Tip-dating methods are becoming popular alternatives to traditional node calibration approaches for building time-scaled phylogenetic trees, but questions remain about their application to empirical datasets. We compared the performance of the most popular methods against a dated tree of fossil Canidae derived from . CC-BY-NC-ND 4.0 International license peer-reviewed) is the author/funder. It ...

Birth Dates and Admission Dates in Schizophrenia and Bipolar Disorder

The well established phenomenon 0/ seasonality 0/ birth dates (winter excess) and admission dates (summer excess) o/patients with schizophrenia and bipolar disorder was re-examined in a Southern A/rican study 0/ ill-patients.
