Summary: All-trans retinoic acid, a vitamin A derivative, induces synaptic plasticity in human cortical neurons.

The brain has an enormous capacity to adapt to its environment. This ability to continuously learn and form new memories thanks to its malleability, is known as brain plasticity.
Despite finding no specific examples, researchers have proved the existence of a pervasive kind of prime number so delicate that changing any of its infinite digits renders it composite.

“Because contrast suppression is orientation-specific and relies on cortical processing, our results suggest that people experiencing a major depressive episode have normal retinal processing but altered cortical contrast normalization,” write the researchers in their paper.
We know that depression is linked to variations in the way our brains are wired, but new research suggests that people who are going through a depressive episode actually see the world around them differently.
And the team behind the study hopes that a better understanding of how visual information is processed in the brains of people with depression could help to inform our treatment approaches in the future.
Japan is becoming the latest country to issue digital vaccine passports, according to a report, allowing citizens to use proof of inoculation to travel internationally once again.
The digital passport will be available through a mobile app and will be linked to the government’s vaccination program, Japanese news outlet Nikkei Asia reported. Vaccinated citizens currently receive a certificate in paper format.
The passport is in talks to be added to an app that is expected to debut next month as a means to show negative test results.
“Our study has revealed 64 percent of the world’s arable land is at risk of pesticide pollution. This is important because the wider scientific literature has found that pesticide pollution can have adverse impacts on human health and the environment,” said Dr. Tang.
There is concern that overuse of pesticides will tip the balance, destabilize ecosystems and degrade the quality of water sources that humans and animals rely on to survive.
The future outlook
Following on from the video last week all about mTOR, this week I have got one on AMPK. This is yet another protein that has an enzymatic role in the cellular energy systems that keeps us all alive and well, and it performs a natural balancing act with mTOR. As with all the systems in our body, a natural balance is essential for harmony, do we feast or fast, do we exercise hard or relax and meditate, do we sleep as many hours as possible or as few as we can get by on, should our body concentrate on growth or repair? It can all seem like a mine field, so it is often good to start with the essentials to make sure you have a good grasp of what they are, before you venture out of your depth. Hopefully this video will help shed some light these areas so you can find the right routine to help you strike a balance.
