Neural networks in the brain form by an axon extending from one neuron to interact with another. Chemical cues in the neuron microenvironment are responsible for activating the extending axon, but which molecular factors are responsible for interpreting this chemical information into a mechanical force for the axon to reach its destination has been unclear. […]

Key aspects of the aging of human cells can be reversed by new compounds. In a laboratory study of endothelial cells, researchers tested compounds designed to target mitochondria. The number of senescent cells (older cells that have deteriorated and stopped dividing) was reduced by up to 50 percent. Source: Key aspects of human cell aging […]

In countries which already permit embryo research, there are no ‘compelling moral arguments’ why the time limit for experimentation should not be doubled, say ethics experts. This could enable synthetic embryos in the lab which can grow into humans, improved IVF treatment, the creation of ‘organoid’ models of human organs for replacement and research to […]

Effective therapeutics to counteract the formation of amyloid plaques in Alzheimer’s disease and type 2 diabetes are not yet available. Scientists have now come a little bit closer to a solution: They have described a new class of designed macrocyclic peptides that are highly potent inhibitors of amyloid formation.
