When Moms Drink Milk During Pregnancy, Their Children Grow Up Taller
Milk does increase weight and length at birth, and there's a possibility that this actually tracks into adult life.
What's the Latest Development?
A Danish study that followed 685 mother-child pairs in a prospective study over 20 years, tracking milk consumption during pregnancy and the height of the offspring at birth and age 20, suggests that the amount of milk a woman drinks during pregnancy may affect the adult height of her offspring. "After adjusting for the mother’s height, age, body mass index and many other factors, they found that mothers who drank more than five ounces of milk a day — almost all drank low-fat milk — had bigger babies, on average, than those who drank less. This, the authors write, confirms the results of previous studies."
What's the Big Idea?
By the age of 20, children of mothers who drank milk during their pregnancy had an average of 8 percent higher blood levels of IGF-1, or insulin-like growth factor, which promotes bone growth. They were also an average of one half-inch taller. "There aren’t many prenatal dietary or environmental factors identified that explain growth in children," said Thorhallur Halldorsson, a researcher at Center for Fetal Programming at the State Serum Institute in Copenhagen. "Milk drinking may be one. It does increase weight and length at birth, and there’s a possibility that this actually tracks into adult life."

How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
