The UK just switched on an ambitious fusion reactor - and it works

The UK's newest fusion reactor, ST40, was switched on last week, and has already managed to achieve 'first plasma' - successfully generating a scorching blob of electrically-charged gas (or plasma) within its core.


Turns out the powerhouse of our cells could be running at a scorching 50°C

A surprising new study suggests that mitochondria, the 'powerhouse of the cell', actually run at a temperature that's far warmer than the human body.



Scientists have discovered they're running at a sizzling 50°C (122°F), surprisingly much hotter than our bodily average of 37°C ( 98.6°F), and it could force a rethink on how our energy generators actually work.


Scientists might have just discovered a whole new role for the thalamus

The thalamus is a small region that sits in the centre of our brain, and is thought to relay signals from our ears, eyes, mouth and skin to other parts of the brain for processing.



But a new study suggests that it's not just passing on information - it also plays a role in cognitive behaviours, such as making decisions and staying focussed. 


Nerve Cells in the GI Tract are Capable of Regeneration

Scientists at Johns Hopkins have reported interesting new evidence that upends common knowledge about gut nerve cells. Their work suggests that neurons in the mouse digestive tract regenerate, incredibly, about five percent every single day. This study, published in the Proceedings of the National Academy of Sciences could have major implications for how we treat and understand the digestive system. 


The brain sets a unique learning rate for everything we do, by self

Each time we get feedback, the brain is hard at work updating its knowledge and behavior in response to changes in the environment; yet, if there's uncertainty or volatility in the environment, the entire process must be adjusted. A Dartmouth-led study published in Neuron reveals that there's not a single rate of learning for everything we do, as the brain can self-adjust its learning rates using a synaptic mechanism called metaplasticity.


Calculations suggest we could one day Build a Rocket That travels 99.999% the Speed of Light

Theoretical physics often lifts the sanctions we set on our own imaginations.



Whether it's exploring the possibility of warp drives or understanding the rate of the Universe's expansion, we are quick to explore the unknown on our chalkboards until our tech is ready for our ideas.
