Ahh, Autumn
It’s officially Autumn. The weather traditionally would be cooling down on its way to greet Winter. But this has been a strange season, weatherwise.
Fewer jackets are being worn than expected and it’s not unusual to see kids still in shorts. Temperatures have been way warmer than average. Greenhouse gases such as carbon dioxide and methane trap the sun’s heat and have been warming Earth’s atmosphere.
It seems like a warmer Fall would alter the timing of when leaves change their color but trees seem to know better. The leaves are glowing with brilliant reds and yellows and starting to fall in huge numbers.
I used to like to crunch them when I walked down the street. I still do.
Ahh, Autumn. It remains its beautiful self. Now it’s time to get out the rake and gather the fallen leaves.
Crunch, crunch, crunch.

Science of Fall Colors
For years, scientists have worked to understand the changes that occur in trees and shrubs during autumn. Although we don't know all the details, we do know enough to explain the basics to help you enjoy nature's multicolored display. Three factors influence autumn leaf color:
- leaf pigments
- length of night
- weather
The timing of color changes and the onset of falling leaves is primarily regulated by the calendar as nights become longer. None of the other environmental influences – such as temperature, rainfall, food supply – are as unvarying as the steadily increasing length of night during autumn. As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature's autumn palette.
“By bringing the experiences of American women to the fore, ‘Brilliant Exiles’ provides a counternarrative to conventional histories of Americans in Paris that focus on the interwar period and the ‘Lost Generation’ of men such as Ernest Hemingway and F. Scott Fitzgerald,” said curator Robyn Asleson. “The exhibition will highlight alternative approaches to modernism developed by women, as well as the enterprises through which they catalyzed creativity and forged interconnected communities.” "The exhibition reveals the dynamic role of portraiture in articulating the new identities that American women were at liberty to develop in Paris, with works by artists including Berenice Abbott, Alice Pike Barney, Romaine Brooks, Anne Goldthwaite, Loïs Mailou Jones, Henri Matisse, Isamu Noguchi, Pablo Picasso, Man Ray, Anne Estelle Rice, Augusta Savage, Edward Steichen, Alfred Stieglitz, Laura Wheeler Waring and Marguerite Zorach." more »
Jo Freeman Writes: This book is about Raines’ effort to put together a jigsaw puzzle about Union sentiment in Alabama, beginning with his family. Raised in Birmingham, Raines’ ancestral roots are in Winston County in NW Alabama, famous for the legend of the Free State of Winston. According to the legend, a mass meeting was held at Looney’s Tavern in Winston County to decide how to respond to Alabama’s vote to secede from the Union. (pp.121-2) Those present passed a resolution that no state can legally get out of the Union, but if it could, then a county could cease to be a part of the state. Winston County didn’t set up its own independent government; it just asked to be left alone because its citizens didn’t want “to shoot at their neighbors ... or the flag of Washington, Jefferson and Jackson.” more »
"Today’s discussions and dedication of the Faces of Gun Violence Exhibit this afternoon reflect a deep and abiding commitment by the women and men of the ATF to victims and survivors of gun violence. I’m grateful to the ATF and to all of you for being here — especially those who have lost loved ones to gun violence. Your presence honors their memory and fuels our fight for a better, safer future. The community gathered today shares a powerful bond. You are survivors. You are advocates. You are members of law enforcement. You call different places home and you come from different walks of life. But together, you’re bound by extraordinary courage. Your lives have been transformed by gun violence – but you are not defined by it.
You share a commitment — to turn your pain into purposeful action — doing everything you can to prevent another family from enduring the same loss."

"FDA is alerting health care professionals and consumers that unsafe counterfeit versions of Botox (botulinum toxin) have been found in multiple states and administered to consumers for cosmetic purposes. FDA is aware of adverse events, including hospitalizations, linked to the counterfeit Botox. Symptoms included blurred or double vision, difficulty swallowing, dry mouth, constipation, incontinence, shortness of breath, weakness and difficulty lifting one’s head following injection of these products. These symptoms are similar to those seen when botulinum toxin spreads to other parts of the body.FDA takes reports of counterfeit products seriously and is working closely with the Centers for Disease Control and Prevention (CDC), state health departments and manufacturers to help protect the nation’s drug supply." more »
