We were wrong - the testes are connected to the immune system

Last year scientists made the amazing discovery that a set of previously unseen channels connected the brain to our immune system; now, it appears we might also need to rethink the immune system's relationship with the testes, potentially explaining why some men are infertile and how some cancer vaccines fail to provide immunity.


Cannabis reverses aging processes in the brain

Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia. The results are now presented in the journal Nature Medicine.


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. 


Neuroscientists have accidentally discovered a whole new role for the cerebellum

One of the best-known regions of the brain, the cerebellum accounts for just 10 percent of the organ's total volume, but contains more than 50 percent of its neurons.


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.
