The Wood Siding Could Age Badly Unless It's Well-treated, But Otherwise Cool.

Oops

When humans “domesticated” fire 400,000 years ago they made the right combination of conditions – longer periods with close human contact, plus smoke-damaged lungs – for tuberculosis to mutate from a harmless soil bacterium into our number one bacterial killer, according to new research.

"The sun is a mass of incandescent gas, a giant nuclear furnace. Where HYDROGEN is built into HELIUM..." Main reason I remember that, thank you They Might Be Giants

I started stoichiometry today and began with the difference between nuclear and chemical reactions. I drew this equation on the board and asked where this reaction takes place and why it’s important to life and the universe. Blank stares and crickets…the entire class of 45 first-year college students had no clue WTF I was talking about.

Do they even teach earth space science in high school anymore?

Let History Never Forget the Name Enterprise

Just as the captains of the fictional 24th century Starfleet blazed a trail among the stars, the space shuttle Enterprise helped pave the way for future space exploration. 

Fifty years ago, Star Trek debuted with the USS Enterprise as the main space-faring vessel used in much of the Star Trek universe. As such, the vessel holds a treasured place in the hearts of Star Trek fans and is as much of a character in the show as Kirk and Spock. Over three different series and a total of 14 seasons on TV and 13 feature films, the iterations of Enterprise have captured the imaginations and provided inspiration for its fans across the globe. 

This brief history of the shuttle tells the tale of humanity’s first reusable spacecraft. Space shuttles were first built in the late 1970s and were flown in space from 1981 to 2011. Their missions ranged from helping to build the International Space Station to repairing the Hubble Space Telescope.   

It’s All In The Name

The first shuttle was originally to be named Constitution, celebrating the country’s bicentennial and was to be unveiled to the public on Constitution Day, Sept. 17, 1976. However, a massive letter-writing campaign by Star Trek fans prompted President Gerald Ford to suggest the change. In the above photo, we see the shuttle Enterprise rolled out in Palmdale, California, with cast members of Star Trek on Sept. 17, 1976. 

To Boldly Go …

This circular red, white and blue emblem was  the official insignia for the Space Shuttle Approach and Landing Test flights and became a model for future space shuttle mission patch designs, including placing the names of the crew on the patch . The four astronauts listed on the patch are: 

Fred Haise., commander of the first crew 

Charles Fullerton, pilot of the first crew 

Joe Engle, commander of the second crew 

Dick Truly, pilot of the second crew 

First Impressions

In this image, Enterprise makes its first appearance mated to its boosters as it is slowly rolled to the huge Vehicle Assembly Building (VAB) at Kennedy Space Center. Although she never flew in space, shuttle Enterprise underwent a series of fit and function checks on the pad in preparation for the first launch of its sister craft, Columbia.

Not Meant To Be

Enterprise sits on Launch Complex 39 at Kennedy Space Center undergoing tests after completing its 3.5 mile journey from the VAB. Have you ever wondered why Enterprise never went into space? Converting Enterprise from a training vehicle to space-worthy one was too cost prohibitive, our engineers felt.

Engage

Commander Fred Haise and pilot Charles Fullerton are seen in the cockpit of Enterprise prior to the fifth and final Approach and Landing Test at Dryden Flight Research Center (Armstrong Flight Research Center). The tests were performed to learn about the landing characteristics of the shuttle.

Fair Winds And Following Seas

Alarming disparities in health outcomes could be prevented by breastfeeding

A new study published in the Journal of Pediatrics showed that black infants had more than twice the deaths of whites attributable to lack of optimal breastfeeding. Black infants also had more than three times the rate of necrotizing enterocolitis, a devastating disease of preterm infants, attributable to suboptimal rates of feeding with their mother’s own milk.

White women initiate breastfeeding at much higher rates than black women and slightly higher rates than Hispanic women; moreover, white women breastfeed longer and have higher rates of exclusive breastfeeding. Current rates for black, white, and Hispanic women were defined as “suboptimal breastfeeding.” This is the first study to show how these disparities translate into differences in health outcomes.

“If mom can’t go to work, she’s not getting paid. This may spell the difference between making rent that month, or keeping the lights on, or paying for basic needs,” said Dr. Melissa Bartick, assistant professor of medicine at Cambridge Health Alliance and Harvard Medical School, and lead author of the study. “When I first saw our results, I cried.”

It is recommended that women breastfeed each child exclusively for the first six months of life, followed by continued breastfeeding while complementary foods are introduced for at least the first year of life.        Credit: © gamelover / Fotolia

I learned something… disturbing… today:

In 1860-something this guy named Charles Lutwidge Dodgson wrote a book about determinants. According to my professor, for years it was the book on determinants. Now here’s my problem: Dodgson was his real name. But the name you probably know him by? Lewis Carroll.

The dude that wrote Alice in Wonderland also wrote a book about determinants. 

Maybe that’s why they’re so freaking weird.
