“A Flash in the Pan”

The phrase “A flash in the pan” has been in use since the late 1600s.

This phrase derives from a real flash in a real pan. Flintlock muskets used to have small pans to hold charges of gunpowder. An attempt to fire the musket in which the gunpowder flared up without a bullet being fired was a”flash in the pan.”

This is why the phrase’s meaning is “Something which disappoints by failing to deliver anything of value, despite a showy beginning.”

Wisdom to ponder…

Alexis de Tocqueville

1805 ~ 1859

French historian, political thinker, and writer who traveled extensively throughout America.

“The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.”

“The American Republic will endure until the day Congress discovers that it can bribe the public with the public’s money.”

“In politics, shared hatreds are almost always the basis of friendships.”

“There are many men of principle in both parties in America, but there is no party of principle.”

“There are two things which a democratic people will always find very difficult – to begin a war and to end it.”

“Nothing conceivable is so petty, so insipid, so crowded with paltry interests, in one word, so anti-poetic, as the life of a man in the United States.”

“History, it is easily perceived, is a picture-gallery containing a host of copies and very few originals.”

Which smells worse…
cotton or synthetic?

The Science of Stinky Shirts

Everyone knows not to leave gym clothes in a bag or locker too long – do this and you’ll risk clothes so stinky you’d rather just throw them out than waste time washing away the stench.

However, you may have noticed that some clothes stink less than others, such as clothing made from cotton. On the other hand, synthetic materials like polyester tend to harbor odors, even  after repeated washing. So what makes the difference?

Researchers at Ghent University in Belgium set out to determine both the cause of malodor and why it persists on synthetic fibers more than cotton.

In a study published inApplied and Environmental Microbiologyin August, twenty-six subjects wearing naturalor synthetic fibers participated in an hour-long spin class, after which they deposited their workout gear in plastic bags and stored them in the dark-conditions analogous to tossing the workout clothes in a gym locker. Twenty-eight hours later, the shirts were sniffed by a trained team of odor connoisseurs and rated for their stench.

It turns out, synthetic shirts stank more than shirts made of natural fibers. On a scale from -4 (very unpleasant) to +4 (very pleasant), the cotton shirts achieved a score of -0.61±1.08 while the polyester shirts achieved a score of -2.04±0.90 – that’s a serious (and significant) difference in stink.

To find out what was causing the increased smell on synthetic shirts, scientists swabbed the armpit regions of subjects and found abundant populations ofMicrococcusspp. Interestingly, these organisms are not found in abundance on armpit skin, but conditions on synthetic shirts appear to promote their growth.

Micrococcus luteuscolonies on a blood agar plate.

So what causes the smelly odors that stick to these synthetic fibers?

Human axillary cells secrete non-volatile
,long-chain fatty acids that have no natural odor. However, the Micrococci found more abundantly in the looser, more airy weave of synthetic fibers than in the tighter weave of cotton are capable of breaking down these molecules into shorter, more volatile compounds that make us wrinkle our noses.

To explore this idea further, the team took a few pungent species of bacteria and tried growing them in Petri dishes coated with seven different fabrics: polyester, acryl, nylon, fleece, viscose, cotton, and wool.

The results were mixed. Cotton grew very few smelly germs, akin to earlier findings, while the microbes continued to swarm over polyester.

These findings may help clothing manufacturers produce clothing that is both breathable and cool, but limits microbial growth by strategically placing different weaves of fibers in different areas of the garment.

“Believe half of what you see

“Science and everyday life cannot and should not
be separated.”

Rosalind Franklin

Credit for the discovery of the structure of the DNA molecule often goes exclusively to James Watson and Francis Crick in 1953. However, these two scientists borrowed heavily from the work of Rosalind Franklin before constructing their model of the DNA double helix.
Rosalind, an English chemist, performed X-ray diffraction studies on DNA in 1953. Her studies were crucial in eventually revealing the illusive double helix structure. She never received a Nobel prize as Watson and Crick did in 1962. She tragically died of ovarian cancer in 1958 at the young age of 37 in the midst of studying the structures of the polio and tobacco mosaic viruses.
The famous “photo 51” showing the x-ray diffusion pattern of DNA taken by Franklin in 1953. It was shown to Watson and Crick without her knowledge. Only after seeing this photo, Watson and Crick realized that DNA could only have a double helical structure.

However, after her death, Watson and Crick made it abundantly clear in public lectures that they could not have discovered the structure of DNA without her work. However, because the Nobel Prize is not awarded posthumously, Rosalind Franklin could not be cited for her essential role in the discovery of the physical basis of genetic heredity.
