For The First Time, Scans Link Childhood Stress With Changes to Key Adult Brain Regions

Posted by in category: neuroscience

Traumatic and stressful events in childhood can affect the brain into adulthood, scientists have shown, identifying for the first time specific alterations to key brain structures in the amygdala and the hippocampus.

New Technique Used to Spot Possible Super-Earth in Alpha Centauri’s Habitable Zone

Posted by in category: space

Astronomers using a new technique may have not only found a super-Earth at a neighbouring star, but they may also have directly imaged it. And it could be nice and cozy in the habitable zone around Alpha Centauri.

Social media must not be allowed to destroy democracy, says the EU President

Posted by in categories: government, information science, law

All governments across the globe are the same they don’t want a free flow of information that would challenge their authority and decisions that they think are good for us, maybe because they want to maintain law and order in society.

I am against the control of social media by the government and I am also against the algorithms which are designed to make people addicted to social media by showing the thing that appeals most to them for profit.

What are your opinions on this topic, how we can achieve the balance between these challenging aspects of social media use?

Chronic unpredictable stress induces depression-related behaviors

Posted by in categories: genetics, neuroscience

Previous studies have shown that AgRP neurons in the arcuate nucleus (ARC) respond to energy deficits and play a key role in the control of feeding behavior and metabolism. Here, we demonstrate that chronic unpredictable stress, an animal model of depression, decreases spontaneous firing rates, increases firing irregularity and alters the firing properties of AgRP neurons in both male and female mice. These changes are associated with enhanced inhibitory synaptic transmission and reduced intrinsic neuronal excitability. Chemogenetic inhibition of AgRP neurons increases susceptibility to subthreshold unpredictable stress. Conversely, chemogenetic activation of AgRP neurons completely reverses anhedonic and despair behaviors induced by chronic unpredictable stress.

OEC promoting AI in Africa.

Ranjan KC


Artificial intelligence (AI) is learning more about how to work with (and on) humans. A recent study has shown how AI can learn to identify vulnerabilities in human habits and behaviours and use them to influence human decision-making.

AEgIS on track to test freefall of antimatter

Posted by in category: physics

It’s a fundamental law of physics that even the most ardent science-phobe can define: matter falls down under gravity. But what about antimatter, which has the same mass but opposite electrical charge and spin? According to Einstein’s general theory of relativity, gravity should treat matter and antimatter identically. Finding even the slightest difference in their free-fall rate would therefore lead to a revolution in our understanding. While the free fall of matter has been measured with an accuracy of around one part in 100 trillion, no direct measurement for antimatter has yet been performed due to the difficulty in producing and containing large quantities of it.
