Breast milk linked to significant early brain growth in preemies

Feeding premature babies mostly breast milk during the first month of life appears to spur more robust brain growth, compared with babies given little or no breast milk.

Studying preterm infants in the Neonatal Intensive Care Unit (NICU) at St. Louis Children’s Hospital, the researchers found that preemies whose daily diets were at least 50 percent breast milk had more brain tissue and cortical-surface area by their due dates than premature babies who consumed significantly less breast milk.

The researchers, at Washington University School of Medicine in St. Louis, presented their findings May 3 at the annual meeting of the Pediatric Academic Societies, in Baltimore.

“The brains of babies born before their due dates usually are not fully developed,” said senior investigator Cynthia Rogers, MD, an assistant professor of child psychiatry who treats patients at St. Louis Children’s Hospital. “But breast milk has been shown to be helpful in other areas of development, so we looked to see what effect it might have on the brain. With MRI scans, we found that babies fed more breast milk had larger brain volumes. This is important because several other studies have shown a correlation between brain volume and cognitive development.”

The study included 77 preterm infants. The researchers retrospectively looked to see how much breast milk those babies had received while being cared for in the NICU. Then, the researchers conducted brain scans on those infants at about the time each would have been born had the babies not arrived early. All of the babies were born at least 10 weeks early, with an average gestation of 26 weeks, or about 14 weeks premature. Because they are still developing, preemies typically have smaller brains than full-term infants.

First author Erin Reynolds, a research technician in Rogers’ laboratory, said in gauging the effects of breast milk on the babies’ brains, the researchers didn’t distinguish between milk that came from the babies’ own mothers and breast milk donated by other women. Rather, they focused on the influence of breast milk in general.

“As the amount of breast milk increased, so did a baby’s chances of having a larger cortical surface area,” Reynolds said. “The cortex is the part of the brain associated with cognition, so we assume that more cortex will help improve cognition as the babies grow and develop.”

Preterm birth is a leading cause of neurologic problems in children and has been linked to psychiatric disorders later in childhood. Rogers and her team plan to follow the babies in the study through their first several years of life to see how they grow, focusing on their motor, cognitive and social development. As the babies get older, the researchers believe they will be able to determine the effects of early exposure to breast milk on later developmental outcomes.

“We want to see whether this difference in brain size has an effect on any of those developmental milestones,” Rogers said. “Neonatologists already believe breast milk is the best nutrition for preterm infants. We wanted to see whether it was possible to detect the impact of breast milk on the brain this early in life and whether the benefits appeared quickly or developed over time.”

Rogers said further investigation is needed to determine specifically how breast milk affects the brain and what is present in the milk that seems to promote brain development. She explained that because all of the babies in the study were born early it isn’t clear whether breast milk would provide similar benefits for babies born at full term.

A team of scientists has developed “robot flies” about the size of a quarter that can perch on almost any surface.

The perching works using static electricity. Each drone carries a tiny copper electrode on its head. When the electrode is energized, it creates a static charge that sticks the robot to a surface. Turning off the electrode sends the little drone back into the air.

Perching is important because it makes the robots more energy efficient. Perching is up to a thousand times more energy-efficient than hovering in place, the researchers say.

What is it Like to Visit Jupiter?

Jupiter is the largest planet in our solar system. For some perspective, if it were hollow, more than 1,300 Earths could fit inside of it! The giant planet contains two-thirds of all the planetary mass in the solar system and holds more than dozens of moons in its gravitational grip. But what about a visit to this giant planet?

Let’s be honest…Jupiter is not a nice place to visit. It’s a giant ball of gas and there’s nowhere to land. Any spacecraft – or person – passing through the colorful clouds gets crushed and melted. On Jupiter, the pressure is so strong it squishes gas into liquid. Its atmosphere can crush a metal spaceship like a paper cup.

Jupiter’s stripes and swirls are cold, windy clouds of ammonia and water. Jupiter’s Great Red Spot is a giant storm BIGGER THAN EARTH! This storm has lasted hundreds of years.

Since Jupiter’s atmosphere is made up of mostly hydrogen and helium, it’s poisonous. There’s also dangerous radiation, more than 1,000 times the lethal level for a human.  

Scientists think that Jupiter’s core may be a thick, super hot soup…up to 50,000 degrees! Woah!

The Moons

Did you know that Jupiter has its own “mini solar system” of 50 moons? Scientists are most interested in the Galilean satellites – which are the four largest moons discovered by Galileo Galilei in 1610. 

Today, Galileo would be astounded to know some of the facts about these moons. The moon Io has active volcanos. Ganymede has its own magnetic field while Europa has a frozen crust with liquid-water underneath making it a tempting place to explore for future missions.

When Juno arrives to Jupiter on July 4, it will bring with it a slew of instruments such as infrared imager/spectrometer and vector magnetometer among the half a dozen other scientific tools in its payload.

Juno will avoid Jupiter’s highest radiation regions by approaching over the north, dropping to an altitude below the planet’s radiation belts – which are analogous to Earth’s Van Allen belts, but far more deadly – and then exiting over the south. To protect sensitive spacecraft electronics, Juno will carry the first radiation shielded electronics vault, a critical feature for enabling sustained exploration in such a heavy radiation environment.

Curving and bending a ball using the magnus effect is common in every sport. The effect can be reversed though - kick the ball the same way, and it will bend in the opposite direction!  

Thanks to Nicole from @fuckyeahfluiddynamics for explaining the reverse magnus effect in this video!
