There is a crazy thrill in finding a vintage recipe. It's a window into a simpler lifestyle, one free of fast food, nuked frozen meals, instant this or suddenly that. Equally, there is self-therapy in adding a few pantry items into a large mixing bowl and watching a transformation while stirring.

Vintage soda biscuits, an 81-year-old recipe, calls for "sour milk." In our day, this equates to buttermilk. In our great-grandmother's world, it meant taking one tablespoon of vinegar or lemon juice, then adding in fresh milk to complete a full cup measurement. It's a bit magical in the blink of an eye, the milk begins to curdle or "sour."

While tempting, don't skimp in following each basic step in preparation. Sifting is important. Using a pastry blender quickly unifies the dry ingredients with the small amount of butter listed. When preparing these for the first time, note that altitude can vary cooking times and may require adding or subtracting flour. This recipe is adapted from a 1936 edition of "Western Cook Book," compiled by Kay Morrow.

VINTAGE SODA BISCUITS

Servings: 8

1 cups flour

teaspoon salt

teaspoon sugar

teaspoon baking soda

1 tablespoons butter, shortening or margarine (I recommend butter), room temperature

1 cup sour milk or buttermilk

Sift together all dry ingredients into a large bowl: flour, salt, sugar and baking soda.

Using a pastry blender, cut in butter to the dry ingredients, making sure all have been well-mixed.

Slowly add in buttermilk, stirring with a large spoon or spatula. A soft ball of dough should form. If mixture is too wet, add in more sifted flour in small amounts.

Prepare cookie sheet or baking pan with cooking spray. Spoon drop (as you would cookies) 8 rounds of dough, separating them evenly on the pan.

In 475 degree oven, bake 12-14 minutes until the edges are a light golden brown, then serve with your favorite jam, jelly, honey butter, soft cheese or, even better, gravy.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
