...with the environment inside the womb and its long-lasting impact on the growing fetus - a process known as "fetal programming." Maternal influences such as alcohol or drug use, poor nutrition and stress are known to affect the level of hormones in the mother's body. It is thought that biochemical changes in the uterus have an impact on the baby's development, affecting its birth weight and even its future risk of disease, among other things...
Glaciers are thought to change at, well, a glacial pace. Certainly that has been true throughout the planet's history. The current ice age - known as the Pilocene-Quatenary glaciation, which began 2.6 million years ago - has witnessed some 20 cycles of glacial (freezing) and interglacial (thawing) periods, with ice sheets advancing and retreating completely on roughly 100,000-year time scales. But scientists are unsure exactly what prompts the shifts in cycles...
...study published in the Feb. 12 issue of Science indicates that the balance of the world's ice may be shifting faster than scientists thought, which may have consequences in a warming world. A team of scientists traveled to the Spanish island of Mallorca, where they visited a coastal cave that has been submerged off and on by the Mediterranean Sea for hundreds of thousand of years, as glacial periods have waxed and waned. They dated the layers of the mineral calcite, which were deposited by the seawater in rings on the cave walls, as on a bathtub...
...impacts of global warming - has refrained from estimating how fast those ice sheets could melt and contribute to sea level rise. Dorale's paper suggests the possibility that ice sheets may respond much more dynamically to changes in temperature, forming and melting at rates that are quicker than previously thought. "There might be a feedback with regards to ice melting," says Dorale. "This is speculation, but it might point at some sort of catastrophic ice sheet dynamic...
...Last year the International Swimming Federation banned the use of non-textile swimsuits that were thought to cause many new world records. Do you think these suits gave you a clear benefit...
