ETH researchers have used computer simulations to show that tissue structure in different types of cancer is decisive in determining how a tumour develops. This information could make it possible to treat patients in a more targeted manner in future. The fact that every tumour is different makes cancer treatment one of the most complex...

Scientists found genes, which could be linked to longevity in humans
There’s never going to be some kind of a magical potion that makes you live longer. However, scientists are looking at all the ways that could increase the lifespan and maybe solve aging. Every little piece of that puzzle matters. For example, there are genes that have been previously found to make fruit flies live...

First-in-human implant of a “closed-loop” bioelectronic research system
Researchers at Oxford University have implanted a novel closed-loop research platform for investigating the role of the pedunculopontine nucleus (PPN) – a brainstem nucleus – in Parkinson’s-like Multiple Systems Atrophy (MSA). The MINDS feasibility trial involves a 5-subject first-in-man clinical trial with the novel closed-loop brain pacemaker to target the pedunculopontine nucleus (PPN) stimulation in patients with...
