Scientist Crack the Brain's Memory Code
Given that the brain's synaptic components last but a short time, it has been a mystery to scientists how the brain stores memories, which can last nearly an entire lifetime.
What's the Latest Development?
Scientists believe they have cracked the code used by the brain to store memories. A team of Canadian and American researchers have found a plausible way of encoding synaptic memory in the brain using microtubules, which are major components of the structural system which supports the integrity of the brain's neurons. "Microtubules define neuronal architecture, regulate synapses, and are suggested to process information via interactive bit-like states of tubulin." It is the first time scientists have found a code connecting microtubules to synapses.
What's the Big Idea?
The popular analogy of the brain to a computer is effective in much of what the brain does, such as processing raw data into recognizable patterns. When it comes to memory, however, the analogy falls apart. There is no central hard drive on which the brain appears to store memory. In fact, the synaptic components that are believed to process and store memory are relatively short-lived, though memories can last a lifetime. By using microtubules to better understand memory, scientists hope to combat memory-related disease like Alzheimer's.

What makes a life worth living as you grow older?
- Dr. Ezekiel Emanuel revisits his essay on wanting to die at 75 years old.
- The doctor believes that an old life filled with disability and lessened activity isn't worth living.
- Activists believe his argument stinks of ageism, while advances in biohacking could render his point moot.
The Amazon Rainforest is often called "The Planet's Lungs."
- For weeks, fires have been burning in the Amazon rainforest in Brazil, likely started by farmers and ranchers.
- Brazil's president, Jair Bolsonaro, has blamed NGOs for starting the flames, offering no evidence to support the claim.
- There are small steps you can take to help curb deforestation in the Amazon rainforest, which produces about 20 percent of the world's oxygen.
Emojis might contain more emotional information than meets the eye.
- A new study shows that people who frequently used emojis in text messages with potential dates engaged in more sexual activity and had more contact with those dates.
- However, the study only shows an association; it didn't establish causality.
- The authors suggest that emojis might help to convey nuanced emotional information that's lacking in strictly text-based messaging.
