Baby Pacifiers Not Good For Boys – The Daily Orbit

Is the pacifier putting a lid on boy’s emotional growth?

Scientists make memory predictions with a new model.

And whole lot of space time!

Get ready for story time on today’s Daily Orbit!

Hello Orbiters, I’m Emerald Robinson….welcome to the Daily Orbit!

The Messenger is sending us new messages about the origin of Mercury. Turns out the planet closest to the sun contains high levels of magnesium and sulfur on its surface, making its composition quite different from the other planets.  Concentrations of sulfur are about 10 times that found on Earth.  Data from Messenger’s spectrometer show that the planet’s volcanic regions formed from upwellings of rocks that are also unique to Mercury.  The Planetary Data System have made Messenger’s images and measurements of the planet available to the public.

How many times have you heard: “he’s just so emotionally unconnected!” Well, maybe it’s because he used his pacifier a little too long.  New research discovered that pacifiers might affect the emotional state of young boys by limiting the number of facial expressions that can be practiced in infancy.  Researchers explain that by mimicking what another person is doing facially, a child creates some part of the feeling for itself.  Infants don’t initially understand the words we say, so facial expressions help us communicate with them.  The study saw no effect on pacifier use in the development of baby girls.  Researchers say this is because girls advance earlier in their emotional development.  I know a few men who definitely sucked on their “passies” longer than they should have!

Wish you knew the best way to get your memory to work?  Well, scientists are looking at just that!  New research shows that it is possible to predict how well people will remember information.  Using EEG sensors, scientists monitored brain activity to see when a person seemed to understand the material or when they needed to study again.  Researchers hope their work will lead to improvements in how students learn, particularly what training works best for different  types of people.

And boy there’s a lot going on in space today! The Curiosity Rover has just witnessed its first eclipse on Mars.   The space probe snapped images of the moon Phobos coming between the Red Planet and the Sun.   Scientists say it’s important to understand Phobos’ orbit as it is slowly spiraling into Mars.  Curiosity has been exploring Mars since early August, and is continuing on its mission. It is now 950 ft from its landing spot and nearing a rock that NASA plans to study before moving to its next destination.  Good luck Curiosity and keep up the good work.

(Reading a book) Once upon a time in a galaxy far, far away there was a light and that light travel many, many light years, 13.2 billion to be exact, where it finally was picked up by NASA’s telescopes.  The Spitzer and Hubble space telescopes have identified the furthest galaxy yet   This light captured by the telescopes was from when the universe was a wee little 500 million years old.  Astronomers say that this galaxy contains only about one percent of the Milky Way’s mass, which confirms the theory that earlier galaxies were very tiny.  The End.  I just love a good galaxy story :)

That does it for today’s Daily Orbit.  See you tomorrow boys and girls!
