appears to be of Caradoc age. The major episode may have begun in Caradoc time and lasted much of Ashgill time, when a major ice-sheet covered at least North-Central and West Africa which was then centered near the South Pole. However, independent palaeontological and sea-level evidence ...
The supposed ramifications of the Little Ice Age, a period of cooling temperatures straddling several centuries in northwestern Europe, reach far beyond meteorology into economic, political, and cultural history. The available annual temperature series from the late Middle Ages to the end of the ninet...
Methionine restriction (MetR) extends lifespan in various organisms, but its mechanistic understanding remains incomplete. Whether MetR during a specific period of adulthood increases lifespan is not known. InDrosophila, MetR is reported to extend lifespan only when amino acid levels are low. Here, ...
However, two smaller glaciers in the Robson area and the main tongue of Small River Glacier have outermost 'Little Ice Age' moraines that date from the first decades of the AD 1700s. All glaciers examined in the Mount Robson area have several well-developed moraines dating from the period ...
The Little Ice Age (LIA; ca. 1450–1850 C.E.) is the best documented cold period of the past millennium, characterized by high-frequency volcanism, low solar activity, and high variability of Arctic sea-ice cover. Past studies of LIA Atlantic circulation changes have referenced the North Atl...
The most vulnerable gestational period for disruptions within the maternofetoplacental unit to influence autism risk has yet to be determined, though some studies found an association between increased mid-gestation maternal stress and autism risk [18, 19]. The fetal HPA axis matures during this ...
Given dating errors associated with the varve chronologies and the Greenland ice-core timescales, the cold interval can be considered to reflect a regional (possibly global) climatic cooling, which is often referred to as the '8.2 kyr BP cooling event'. However, the younger age of the cold ...
From birth to age 2 is perhaps the greatest period of discovery for your child. Like a little scientist, he'll begin to solve the mysteries of his strange new world by observing and experimenting, and your home is his laboratory. Birth to 6 months Having toys scattered around your home ...
We place most confidence on this cluster of ages to constrain the timing of ice sheet retreat as we suspect the 3 oldest ages have some inheritance from a previous ice free period. Three additional ages from the adjacent island Karmøy provided an average age of 20.9 ± 0.7 ka, further ...
The margin of the Greenland Ice Sheet retreated rapidly during the first few thousand years of the Holocene. During this period of relative warmth, known as the Holocene thermal maximum, ice core records identify a significant short-lived cooling event at approximately 8.4–8.0 ka cal. yr BP ...
