"If you’ve ever been in a Santa Fe home with Saltillo tile floors (a type of terracotta tile that originates in Saltillo, Coahuila, Mexico), you may have noticed a tile here or there that has paw prints. You probably wondered: What’s the story?
In the Saltillo tile manufacturing process, wet clay tiles are laid in wide open spaces where they semi-dry in the sun. Once the tiles are dry enough to move to a kiln, they are removed from the ground and kiln-fired in order to fully harden. While laid about on the ground, animals who are common to the area roam and wander and leave their marks on the tiles.
The most common animals to roam the grounds where Saltillo tiles are drying in the sun can include (but are not limited to): coyotes, dogs, cats, pigs, chickens, birds, and even wolves in rare circumstances. Dog and coyote paw prints are the most common to find.
There is actually a superstition in the Southwest United States and Northern Mexico that every house with a floor laid with Saltillo tile must have a “protector” tile set within its boundaries for good luck. That protector tile will bear the imprint of an animal’s foot print and is often laid in a very visible area. If you have such a tile in your Santa Fe home, lucky you! But if you are not the superstitious type, then at least you have a good conversation piece to share with guests!"

"Scientists found prolonged sleep loss makes the brain's immune cells go into overdrive, leading to long-term damage.
Astrocytes, which normally eliminate unnecessary synapses, begin breaking down more brain connections and debris in sleep-deprived animals.
While this may initially serve as a protective mechanism, clearing potentially harmful debris and rebuilding worn circuitry, it could be detrimental in the long run. Microglial cells, which remove damaged cells and debris, also show increased activity after chronic sleep deprivation.
This is particularly concerning, as excessive microglial activity has been linked to various brain disorders, including Alzheimer's disease and other forms of neurodegeneration.
The research suggests that sleep loss triggers astrocytes to start breaking down more of the brain's connections and their debris, with portions of synapses literally being eaten by astrocytes due to sleep loss. Most of this remodeling appears to target larger, more mature synapses that are used more intensively. It’s still unclear whether getting more sleep could reverse the effects of sleep deprivation. The findings may explain why lack of sleep increases vulnerability to dementia and other neurological disorders.
Notably, Alzheimer's deaths have increased by 50% since 1999, highlighting the potential link between sleep deprivation and neurodegenerative diseases. Sleep plays a crucial role in maintaining brain health and function, serving as a vital period for neural restoration and cognitive processing. During sleep, the brain undergoes essential maintenance tasks, clearing away toxic byproducts accumulated during wakefulness and consolidating memories.
Research has shown that sleep deprivation can lead to impaired cognitive function, decreased attention span, and reduced problem-solving abilities. Chronic sleep loss may contribute to the development of neurological disorders such as Alzheimer's disease. Sleep allows for the strengthening of neural connections important for learning and memory formation, while pruning unnecessary synapses to optimize brain function. The glymphatic system, which removes waste products from the brain, is particularly active during sleep, highlighting its importance in maintaining neural health. Adequate sleep also supports emotional regulation, with sleep-deprived individuals often experiencing mood swings, irritability, and increased stress levels.
The brain's plasticity, or its ability to adapt and change, is enhanced during sleep, facilitating learning and skill acquisition. Different sleep stages serve unique purposes, with the REM sleep being particularly important for creativity and emotional processing, while slow-wave sleep contributes to physical restoration and memory consolidation. Sleep also plays a role in hormone regulation, including those that affect appetite, stress response, and growth. Insufficient sleep has been linked to increased risk of obesity, diabetes, and cardiovascular diseases, emphasizing its importance beyond just cognitive function.
Furthermore, sleep supports the immune system, with sleep-deprived individuals being more susceptible to infections and illnesses.
The brain's energy consumption is carefully regulated during sleep, allowing for the replenishment of energy stores depleted during wakefulness. This process is crucial for maintaining optimal cognitive performance and overall brain health. In essence, sleep is not merely a period of inactivity but a dynamic state that is fundamental to our brain's ability to function effectively, adapt to new experiences, and maintain long-term health.

"This is an extremely rare yellow cardinal seen in Alabaster, Alabama. Auburn University biology professor Geoffrey Hill says — it is in the same species as the common red cardinal, but carries a genetic mutation that causes what would normally be brilliant red feathers to be bright yellow instead."
