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.
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.
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.
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.
A built-in camera and artificial intelligence can improve the speed and grasping ability of a prosthetic hand, as shown in tests with people missing a hand. Test results and a description of the technology developed by engineers at Newcastle University in the U.K. appear in yesterday's issue of the Journal of Neural Engineering.
