Cell biologists discover crucial ‘traffic regulator’ in neurons
Cell biologists led by Utrecht University’s Professor Casper Hoogenraad have discovered the protein that may be the crucial traffic regulator for the transport of vital molecules inside nerve cells. When this traffic regulator is removed, the flow of traffic comes to a halt.

The resulting ‘traffic jams’ are reported to play a key role in neurodegenerative diseases such as Alzheimer and Parkinson’s disease. The discovery of this traffic regulator may therefore be crucial for a better understanding of the development of neural disorders. The results of their research were published in the scientific journal Neuron on Wednesday 19 April.

Freezing Bubble

A soap bubble exposed to very cold temperatures (-25°C/-13°F) will quickly freeze as ice crystals form and coalesce into an icy sphere. The intricate detail of the expanding crystals can easily be seen as the liquid water transitions to its solid state.

Probiotic in Yogurt Reverses Depression
Researchers at the University of Virginia School of Medicine have reversed depression symptoms in mice by feeding them Lactobacillus , a probiotic bacteria found in live-cultures yogurt. Further, they have discovered a specific mechanism for how the bacteria affect mood, providing a direct link between the health of the gut microbiome and mental health.

Based on their findings, the researchers are optimistic that their discovery will hold true in people and are planning to confirm their findings in patients with depression.

“The big hope for this kind of research is that we won’t need to bother with complex drugs and side effects when we can just play with the microbiome,” explained lead researcher Alban Gaultier, PhD. “It would be magical just to change your diet, to change the bacteria you take, and fix your health and your mood.

The ultimate roadmap of metabolic pathways to produce ATP
The source of energy, for every cell in your body, that keeps everything going is called ATP.
Adenosine triphosphate (ATP) is the biochemical way to store and use energy.
